Social Psychiatry and Psychiatric Epidemiology

BackgroundUp to one-third of medical inpatients experience clinically relevant mental distress, yet many remain untreated. Stepped and collaborative care (SCC) models may improve access to mental health care, but predictors of service uptake are unclear. We examined patient- and ward-level predictors of psychosomatic-psychiatric consultation (PPC). MethodsWe analyzed data from SomPsyNet, a stepped-wedge cluster randomized trial targeting SOMatic inpatients across three Swiss tertiary hospitals, to prevent PSYchosocial distress by a care NETwork. Analyses focused on inpatients screening positive for mental distress. Multiple-imputed logistic regressions assessed predictors of four sequential service-use stages: PPC considered, offered, accepted, and received. ResultsAmong 589 distressed patients, 93.9% were offered PPC, 63.1% accepted, and 83.9% of acceptors received PPC, yielding a 50% overall receipt rate. Patients without Swiss citizenship showed higher odds of acceptance (odds ratio [OR]=1.82 [1.10, 3.00]) and eventual receipt (OR=1.62 [1.01, 2.62]). Being in a Geriatric ward facilitated PCC uptake, while patients from gynecology showed reduced progression through the care pathway. Age, gender, income, education, marital status, and living arrangement showed no statistically robust associations. ConclusionsAlmost two-thirds of mentally distressed medical hospital inpatients accepted an offered PPC, indicating high acceptability. About half ultimately received a consultation, highlighting substantial attrition along the SCC pathway. Ward specialty and nationality were key determinants of PPC uptake. These findings suggest that proactive, ward-oriented consultation-liaison models embedded in routine inpatient care may improve timely and equitable access to mental healthcare, including for migrant and minority patients who are otherwise less likely to access such care.

ObjectiveThis study aimed to identify characteristics that define population need groups with similar mental health service needs within prisons and describe the mix of services required to meet those needs. MethodsMixed methods were used, including three iterative, semi-structured focus groups, followed by an online survey, seeking information on the characteristics that define service needs, how these can identify groups of people who require mental health care in prisons and the services required by each group. Participation was sought from prison health services, prison mental health services, non-government service partners and people with a lived experience. Focus group transcripts and free text survey responses were thematically analysed. Descriptive statistics were generated for online survey responses to Likert Scales to determine the levels of agreement with survey content. ResultsThe characteristics and service needs of four distinct population groups who require mental health care in prisons were defined: indicated prevention, mild, moderate, severe and complex. These groups were delineated using characteristics including presence of a diagnosed mental illness, level of functional impairment, presence of added complexity and service response required. The required service mix varied across need groups, however service types common across all groups included assessments, psychological therapies, peer support, lifestyle interventions and carer support. ConclusionsThe identified need groups and service descriptions will contribute to the evidence required for needs-based planning of mental health care in Australian prisons. This information can be used for planning a responsive, equitable, and needs-based mental health service system within custodial environments.

BackgroundThe COVID-19 pandemic, coupled with concurrent social instabilities, has raised concerns about the long-term impact on the population mental health. While existing studies have primarily focused on the acute phase, less is known about how anxiety and depression symptoms have evolved throughout prolonged societal disruption. This study aimed to identify distinct anxiety and depression symptom trajectories and to determine the individual, relational, and societal protective and risk factors that influence anxiety and depression scores among Belgian adults from 2020 to 2024. MethodsWe used longitudinal data from five waves of the COVID-19 Health Surveys and the BELHEALTH study (n = 10,063) among Belgian adults, collected between April 2020 and June 2024. Anxiety and depression were assessed using the Generalized Anxiety Disorder-7 and the Patient Health Questionnaire-9, respectively. Covariates were selected based on the social-ecological framework and included both time-invariant and time-dependent variables. Latent class linear mixed models identified subgroups with distinct trajectories. Multilevel linear mixed effects models examined associations between symptom severity and predictors across individual, relationship, and societal levels. The final model, selected based on the lowest AIC (Akaike Information Criterion), included the full set of covariates. ResultsFour depression and five anxiety trajectories were identified. While most participants maintained stable mild symptoms, 11.3% experienced increasing depression and 8.4% showed increasing anxiety over time. Financial difficulty, female gender, and younger age were overrepresented in moderate and severe symptom trajectories. Protective factors such as social support, satisfying social contact, and life satisfaction were associated with lower symptom severity. Over time, life satisfaction demonstrated an increasing protective effect, while the influence of social contact on reducing symptoms weakened progressively. Risk factors included financial and job-loss worry, loneliness, psychotropic medication use, and high mental health stigma. ConclusionsOur results demonstrate persistent heterogeneity in mental health responses, with a substantial share of the population experiencing worsening symptoms years after the pandemic began. Public mental health strategies must therefore go beyond short-term crisis response, address long-term risks such as financial insecurity, social isolation, and stigma, while fostering individual and collective resilience.

Depression is a common and clinically significant mental health condition among university students, particularly those experiencing academic failure and course repetition, and is associated with adverse effects on cognitive functioning, emotional regulation, and academic performance. This study evaluated the efficacy of an internet-based cognitive behavioural therapy (iCBT) intervention, MoodGYM, in reducing depressive symptoms among repeating undergraduate students at the University of Zambia Ridgeway Campus. A quasi-experimental quantitative study design was employed. Seventy-five repeating undergraduate students with depressive symptoms were enrolled, with 33 assigned to the MoodGYM intervention group and 42 to a control group. Depressive symptom severity was assessed using the Beck Depression Inventory (BDI) at baseline and after an eight-week intervention period. Statistical analyses included within-group and between-group comparisons, difference-in-differences estimation, and fixed-effects regression modelling. At baseline, participants exhibited predominantly moderate to severe depressive symptoms, with no statistically significant differences between the intervention and control groups. Following the eight-week intervention, the MoodGYM group demonstrated a statistically and clinically significant reduction in depressive symptoms, with median BDI scores decreasing from 22 to 16 (p < 0.001), representing a large effect size (Cohens d = 1.02). In contrast, the control group showed persistence or worsening of depressive symptoms over the same period. Difference-in-differences analysis confirmed a robust intervention effect, with an approximately 10-point greater reduction in depression scores among MoodGYM participants compared with controls (p < 0.001). These findings indicate that MoodGYM is an effective internet-based intervention for reducing depressive symptoms among repeating undergraduate students and offers a feasible and scalable approach to addressing student mental health needs in low-resource university settings.

BackgroundMental well-being encompasses positive psychological functioning, life satisfaction, and engagement with daily activities. It is influenced by multiple interrelated factors, including symptoms of stress, anxiety, depression, and psychological inflexibility. Network analysis provides a data-driven framework for examining the complex interconnections between these components and for identifying elements that may play a central role in the mental well-being system. The present study aimed to identify key elements related to stress, anxiety, depression, and psychological inflexibility associated with mental well-being in individuals seeking online psychological support. MethodsThis cross-sectional study analyzed data drawn from the Online Well-being intervention. A total of 967 Mexican participants were included. A psychological network comprising seventy-four items was estimated, and centrality indices (strength, closeness, and betweenness) were computed to determine the relative importance of individual elements within the network. Network comparisons by gender were conducted to evaluate global and local differences. ResultsThe network revealed multiple inter-domain associations, particularly negative relationships between mental well-being and symptoms of depression, anxiety, negative stress, and psychological inflexibility. Items reflecting self-evaluation and emotional well-being consistently emerged as the most central elements in the network across centrality metrics. Gender-based comparisons indicated overall structural similarity between networks, although differences were observed in the strength of specific connections. ConclusionsNetwork analysis identified central elements linking mental well-being with psychological distress and inflexibility in a population seeking online psychological support. These findings contribute to a systems-level understanding of mental well-being and highlight potential targets for psychological interventions to enhance well-being and reduce distress.

Structured AbstractO_ST_ABSObjectiveC_ST_ABSThis mixed-methods study investigated the lived-experience perspectives of receiving a novel, brief digital mental health intervention after psychological trauma. The online gamified imagery-competing task intervention (ICTI) involves one researcher-guided session followed by self-use. Tested in two randomised controlled trials (GAINS-01; GAINS-02), ICTI led to fewer intrusive memories at week-4, with the reduction sustained over 24 weeks, alongside reductions in post-traumatic stress. Here, we contrasted user experiences of ICTI with an Active Control (AC; music-listening task), and explored longer-term impact in qualitative interviews to contextualise GAINS-02 findings. Methods and AnalysisThe GAINS-02 trial randomised healthcare staff experiencing intrusive memories after work-related trauma to ICTI (N=40), AC (N=39), or treatment-as-usual (TAU; N=20). Expectancy was assessed before the researcher-guided session (Day 0), acceptability at week-4, and usage tracked for 24-weeks. Semi-structured interviews (N=27) were conducted in ICTI and AC arms only (15 at week-4; 12 during 12-24-weeks). Interviews were analysed using reflexive thematic analysis. ResultsPrior to use, many trial participants did not think the intervention would work, favouring AC over ICTI. However, after completing the tasks, participants found ICTI more acceptable and relevant to intrusive memories than AC. After the one guided session, median ICTI usage the next four weeks was 4.00 times with little additional use (once more) over the next 20 weeks because of lack of need. Potential implementation facilitators included ease of use, and advantages over existing interventions due to not needing to talk about the trauma, brevity, and lesser resource commitment. Perceived barriers included a lack of staff and manager education about the nature and consequences of intrusive memories, with a need for workplace buy-in and demonstration of organisational benefits. ConclusionHealthcare staff experiencing workplace-related trauma found ICTI to be acceptable and effective for reducing intrusive memories with low effort and emotional burden, even among participants who initially expressed scepticism. Participants highlighted implementation considerations including offering ICTI both within and outside the workplace, and providing a self-guided version of ICTI with optional support. Future work should assess cost-effectiveness, impacts on presenteeism and retention, and real-world implementation including the feasibility and effectiveness of a self-guided ICTI. Summary BoxO_ST_ABSWhat is already known on this topicC_ST_ABSIn a previous randomised controlled trial (GAINS-01) with Intensive Care Unit (ICU) staff exposed to work-related trauma, a brief online gamified imagery-competing task intervention (ICTI) reduced intrusive memories compared to usual care at four-weeks. What this study addsThe GAINS-02 randomised controlled trial replicated GAINS-01 and extended results by comparing ICTI to an active control (AC; music listening) task, enrolling hospital staff from outside ICU, and a follow-up period of 24-weeks. Qualitative interviews found that, despite initial scepticism from healthcare staff prior to using the intervention, ICTI was more acceptable than an AC due to specific effects on swiftly reducing intrusive memories and requiring minimal support or usage after an initial researcher-guided session. After one guided session, ICTI was used 4 more times in the first four weeks, with little additional usage (once) thereafter because of lack of need (i.e., no longer experiencing intrusive memories). How this study might affect research, practice or policyICTI is an efficacious scalable intervention to relieve staff of intrusive memories with effects sustained for at least 6-months. It was found to be more acceptable to participants than alternatives, requiring less time commitment than standard psychological treatments.

BackgroundDespite widespread recognition of the value of lived experience (LE) involvement in healthcare research and increased LE involvement activity, we lack established implementation methods and instruments for reporting and evaluating impact. We present a protocol for an innovative LE-led Impact Log tool and co-production framework, which may help to address some fundamental barriers to co-production. The Impact Log will be implemented within a five-year multidisciplinary transdiagnostic research project on severe mental illness, the Brain and Genomics Hub of the UKRI Mental Health Platform, and is also designed for wider adaptation and use. Part I presents a short narrative review of literature pertaining to defining, evaluating, and enhancing the impact of co-production, to provide in-depth background and aid future development. Part II presents the Impact Log protocol. MethodsThe Impact Log framework is designed to integrate inclusive and impactful co-production throughout all research stages, and to record and evaluate its impact across three domains using an accessible short form. The three research domains are: design and delivery; interpersonal and environmental aspects; systems and processes. Impact Log design and implementation is led by LE study leads and a specialist advisory panel, who are integrated fully within the wider research team, and all have combined research experience and LE of bipolar or psychotic disorders. All Hub research participants will be offered accessible opportunities for remunerated lived experience input, and there will be outreach to ensure diverse representation, aided by the Hubs charity partners. Data collection and analysis will be LE led and will include iterative analysis to inform continuing development. Diverse formal and informal dissemination throughout the project will maximise wider stakeholder engagement. DiscussionThe potential value of this research is to implement a novel tool and framework for facilitating, recording and evaluating co-production in complex mental health research, which can be adapted for wider use. Strengths in design are LE leadership and cross-cutting LE research integration, incorporation of multiple domains, and a focus on facilitating diversity and inclusion within co-production. Potential limitations for this project and wider adaptation may include limited resources, risk of bias and health challenges. Lay SummaryWe have provided a brief lay summary to help people without a research background understand our project. This article explains our plan to develop and test a new way of understanding how research changes when people with personal experience of a mental health condition are part of the research team. We are a team of mental health researchers and many of us have direct experience of bipolar and psychosis. We work alongside other researchers, including people who might also have worked in mental health services or in charities that provide support. Our research project aims to better understand what is happening in the brain, body, lives and experiences of people who have bipolar and psychosis. Many people believe that research is better when it includes the views of people who have direct experience of the health condition being studied. This is called "lived experience". We have developed a structured approach to make sure that people with lived experience are meaningfully involved in our research team. We have also created a simple tool, called the Impact Log, to record when lived experience members contribute and to help us understand how their involvement influences the research. Finally, we wanted to better understand what other researchers have said about lived experience involvement. We reviewed many published academic studies and reports and brought their findings together in what is called a "narrative review". This review summarises what is already known about the difference lived experience involvement can make in research.

PurposeTo address high levels of depression and anxiety among college students, innovative, feasible, and effective treatment approaches with high potential for dissemination in university counseling centers are needed. This pilot study aimed to develop a toolkit and training intervention to support implementation of nature-based physical activity into group therapy in a university counseling center, and to evaluate the feasibility, acceptability, and preliminary effectiveness of the intervention from the perspective of both therapists and participating clients. MethodsPhysical activity researchers and staff therapists collaborated to develop an 8-week therapy group, with each 90-minute weekly session incorporating discussions of cognitive behavioral strategies for managing anxiety and 30 minutes of moderate-intensity outdoor physical activity. Measures included staff surveys completed pre/post training, standard client assessments (Group Session Rating Scale and Counseling Center Assessment of Psychological Symptoms), and a group facilitator interview. ResultsIn Spring 2025, six students enrolled in the inaugural group. All students completed the group, demonstrated high satisfaction (M=8.78/10 across all sessions), and reductions in depression (d=0.96) and social anxiety (d=0.82). Staff confidence to discuss and recommend nature-based physical activity increased from 7.05 (pre-training) to 8.48 (follow-up). Group therapy facilitators reported high enjoyment and desire to continue offering the group. ConclusionThis study highlights an innovative intervention with promise for translation across university counseling center contexts. The toolkit and training intervention developed for this study could provide a blueprint for other university counseling centers to offer similar therapy groups and expand the integration of nature-based physical activity into mental health services.

Objective: Posttraumatic stress disorder (PTSD) after a traumatic birth is a serious but overlooked maternal morbidity, affecting ~20% of women following medically complicated deliveries. PTSD can undermine maternal caregiving. Rapid screening tools suited to busy obstetric settings are lacking. We developed and evaluated a brief screener, derived from the 20-item PTSD Checklist for DSM-5 (PCL-5), to identify PTSD related to childbirth. Study Design: We enrolled 107 women with traumatic childbirth. Participants completed the PCL-5 and the gold-standard clinician diagnostic interview for PTSD (CAPS-5); depression was measured with the Edinburgh Postnatal Depression Scale (EPDS). Bootstrap resampling with LASSO regression identified PCL-5 items most associated with PTSD. Firth logistic regression models estimated diagnostic accuracy. Sensitivity, specificity, area under the ROC curve (AUC), and Youden's J statistic determined performance and optimal cut-off. Results: A six-item version of the PCL-5 (PCL-5 R6), statistically derived from the full scale, showed excellent discrimination for PTSD compared with clinician evaluation (AUC = 0.95; 95% CI, 0.89-1.00). A cut-off score of 7 yielded high sensitivity (0.96) and good specificity (0.83), with an overall diagnostic efficiency of 0.86, detecting most PTSD cases while minimizing false positives. The PCL-5 R6 correlated moderately with the EPDS (rho = 0.53), showing that a depression screen alone cannot reliably detect PTSD. Conclusions: A short, 6-item PCL-5 provides a valid, efficient tool for detecting childbirth PTSD. Its brevity and accuracy make it practical for integration into routine postpartum care, enabling timely mental health screening.

ObjectiveAlthough mental health and healthy lifestyle interventions are associated with functional outcomes in adolescence, the extent to which particular lifestyle factors explain relationships between mental health and outcome are unclear. Here we examined mediating effects of lifestyle factors on relationships between mental health and two functional outcomes measured 2-3 years later as well as the moderating effect of environmental risk factors on mediation strength in early adolescence. MethodsThis study analyzed data from 3 waves of the Adolescent Brain Cognitive Development Study (ages 10-11, 11-12, and 12-13). Mediating effects of sleep quality, screen time, physical activity and Mediterranean diet on the relationships between depression, anxiety, psychotic-like experience (PLE) distress, and total problems with two subsequent functional outcomes (academic functioning and social problems) were examined. Secondary analyses included environmental factors as moderators. ResultsSleep quality mediated 18.5%, 36.3%, 8.3%, and 3.4% of the relationships between depression, anxiety, PLE distress and total problems with academic functioning, respectively. Screen time was the second strongest mediating factor. For social problems, only sleep quality showed > 3% mediation (19.6% - 23.3%). Mediating effects of sleep and screen time on academic functioning decreased as financial adversity increased. Conversely, mediating effects of sleep quality on social problems increased with worsening family conflict, financial adversity, and school environment. ConclusionsThese results suggest that healthy lifestyle factors (in particular sleep quality) may partially explain the associations between mental health and functioning in adolescents and suggest that these effects are modulated by environmental factors. These results may have important implications for future intervention studies.

Burnout, a state of chronic exhaustion often characterized by feelings of emotional exhaustion, cognitive and emotional dysregulation, and psychological distancing, is an increasingly recognized issue within most professions. This syndrome results in diminished job satisfaction, strained interpersonal relationships, and decreased well-being. Socio-demographic factors have been shown to play a role in burnout risk, while trait mindfulness has been identified as an effective method to mitigate it. This study aimed to identify the prevalence of burnout risk and its relationship with mindfulness and socio-demographics among medical researchers. An anonymous, online, cross-sectional survey was administered to corresponding authors published in MEDLINE. The survey consisted of screening and socio-demographic questions, as well as validated assessment tools (i.e., shortened work-related Burnout Assessment Tool [BAT-12] and shortened Freiburg Mindfulness Inventory [FMI-14]). Responses were analysed according to the BAT and FMI guidelines, alongside regression analyses. A total of 1,732 participants completed the survey, yielding a response rate of 1.88%. Overall, 38.8% of participants were at risk or at very high risk of burnout, and the mean mindfulness score was 37.51. Multiple linear regression analysis indicated that sex, age, and employment status were significant predictors of burnout risk, while age and region significantly predicted mindfulness. Hierarchical regression analysis showed that, after controlling for socio-demographic variables, mindfulness was a strong and independent negative predictor of burnout risk. These findings on burnout risk and the influence of mindfulness and socio-demographics could guide future research in developing tailored interventions and policies that improve the well-being of medical researchers.

Armed conflict in Sub-Saharan Africa has exposed millions of civilians to repeated and severe traumatic events, yet the prevalence of posttraumatic stress disorder (PTSD) and its associated determinants across the region have not been comprehensively synthesised. This study aimed to estimate the prevalence of PTSD and examine its associated factors among conflict-affected adult populations in Sub-Saharan Africa. Methodological quality was assessed using the Joanna Briggs Institute (JBI) criteria for cross-sectional and epidemiological studies A systematic search of PubMed, MEDLINE, Embase, Scopus, CINAHL, APA PsycINFO, the Cochrane Library, and the WHO Global Index Medicus (including African Index Medicus) was conducted for studies published between January 1, 2000, and May 31, 2025. Observational studies reporting PTSD prevalence among adults aged 18 years or older exposed to armed conflict were included. Study selection followed PRISMA 2020 guidelines, with independent screening by two reviewers. Random-effects meta-analyses with logit transformation were used to pool prevalence estimates, and determinants were synthesised narratively with emphasis on adjusted effect estimates. Heterogeneity was assessed using the I{superscript 2} statistic. Sixty-eight studies comprising 82,021 participants from 13 countries met inclusion criteria. The pooled prevalence of PTSD was 43% (95% CI, 35.9%-50.0%), with substantial heterogeneity (I{superscript 2} = 99.9%). Prevalence was highest among refugees (79%), followed by internally displaced persons (48%) and residents of conflict-affected communities (34%). Female sex was consistently associated with increased odds of PTSD (pooled adjusted odds ratio approximately 2.0), as were comorbid depression or depressive symptoms (AOR range 4.2-9.5). Additional correlates included cumulative trauma exposure, displacement, poor social support, and substance use. Overall, PTSD is highly prevalent among conflict-affected adults in Sub-Saharan Africa, underscoring the need for integrated, context-sensitive mental health strategies to address the enduring psychological consequences of armed conflict in the region.

The COVID-19 pandemic had substantial impact on healthcare systems across the globe, including psychiatric services. Use of electroconvulsive therapy (ECT), a lifesaving intervention for severe mental illness, was reported to have declined during the pandemic in several countries, but nationwide data remain scarce. Using nationwide data from the Danish National Patient Register, we examined all ECT treatments administered in Denmark from September 2019 to May 2025. Weekly treatment numbers were visualized across the three national COVID-19 lockdowns to descriptively assess changes in ECT use. A notable reduction in ECT treatments was observed in the weeks preceding and during the first lockdown (March 11 to May 18, 2020). A post-hoc estimation indicated approximately 1,366 "missed" treatments during the initial pandemic phase in 2020. When these were added to the 27,033 treatments delivered in 2020, the adjusted total approximated annual treatment volumes in 2019 and 2022, suggesting a temporary disruption rather than sustained decline. In contrast, ECT activity during the second and third lockdowns appeared largely unaffected. These findings suggest that ECT provision in Denmark was temporarily reduced during the initial phase of the pandemic but remained resilient thereafter. In the case of a future pandemic, safeguarding timely access to ECT--particularly in early phases-- should be prioritized given its critical role in the treatment of severe mental illness.

Digital therapeutics for mental health often face low patient engagement, which limits their clinical impact. Interventions that deliver treatment using a video game medium may improve engagement and therapeutic efficacy, but the putative emergence of gaming-related problems remains a concern among clinical stakeholders. We examined whether long-term engagement with Meliora, a video game therapeutic for adult major depressive disorder, was associated with changes in gaming-related problems in a three-arm randomized controlled trial. The intention-to-treat cohort (n = 1,001) had a mean age of 33.4 years (SD 9.3) and 64% were female. The Gaming Addiction Scale (GAS-7) scores decreased from baseline (week 0) to post-intervention (week 12) in the Meliora arm (p = 8.1x10-4) and in the treatment-as-usual arm (p = 6.0x10-6), with no significant change observed in the Sham arm (p = 0.39). Changes in GAS-7 scores were not associated with intervention use hours (Meliora: p = 0.17; Sham: p = 0.28) or with experienced immersion (Meliora: p = 0.93; Sham: p = 0.19). Deterioration analysis found worsening rates from baseline to post-intervention low and comparable across study arms. Analyses in the per-protocol completer cohort ([&ge;]24 h use) corroborated these findings, indicating that even higher use did not lead to increases in gaming-related problems. These results provide evidence that long-term use of a video game therapeutic does not increase gaming-related problems when risks are properly mitigated, suggesting that video games may provide a safe medium for digital therapeutics. Author summaryMany patients use digital therapeutics insufficiently or drop out early, which limits their effectiveness and applicability in healthcare. Video game therapeutics deliver the treatment using an interactive video game as a medium to improve both engagement and therapeutic efficacy. However, extended use of video game therapeutics could inadvertently increase gaming-related problems. We examined whether long-term use of Meliora, a video game therapeutic for adults living with depression, was associated with increased gaming-related problems. We found that using Meliora or a highly similar Sham device did not increase gaming-related problems. Changes in gaming-related problems were not associated with the amount of time participants used the interventions, suggesting that typical use patterns are safe. We also found no relationship between experienced immersion and changes in gaming-related problems, suggesting that subjective immersion is distinct from problematic gaming. This study provides the first clinical evidence that extended engagement with a video game therapeutic does not increase gaming-related problems. These findings suggest that video games can be a safe medium for digital therapeutics in healthcare.

BackgroundAs digital communication becomes central to daily life, psychotherapy increasingly has access to patients electronic media data. While digital phenotyping has been widely studied, less is known about whether incorporating personal communication data, such as text messages, improves clinical outcomes in psychotherapy. ObjectiveTo determine whether integrating personalized text message data into psychotherapy improves depression, anxiety, health related quality of life, and therapeutic alliance, and to examine whether increased access to collateral information influences clinical decision making. MethodsThe Electronic Media and its Impact on Psychotherapy EMAP study was a randomized controlled trial conducted in adult and geriatric outpatient and partial hospitalization settings at an academic psychiatric hospital. Participants receiving psychotherapy for primary depression or anxiety N = 101 were randomized to Electronic Media Enhanced Therapy EME n = 52 or Treatment as Usual TAU n = 49. In EME, research staff reviewed participants text messages prior to sessions using personalized mood related key terms and presented aggregated findings on a HIPAA compliant clinician dashboard. TAU participants received standard care without message review. Outcomes included change scores for PHQ 9, GAD 7, SF 36, and Working Alliance Inventory Short Revised WAI SR. Linear regression and nonparametric tests compared groups. Moderation analyses assessed whether frequency of information access influenced treatment changes. ResultsNo significant between group differences were observed in anxiety or working alliance. Among participants with SF 36 follow up data n = 65 EME participants demonstrated greater improvement in the pain subscale. Greater frequency of information access was associated with increased treatment related changes in the EME group. Access to additional collateral information was associated with more clinical actions but not improved distal outcomes. ConclusionsIntegrating personalized text message data into short term psychotherapy did not significantly improve depression or anxiety, and neither improved nor worsened therapeutic alliance. However, access to greater amounts of collateral information including electronic media influenced clinical decision making, suggesting nuanced and context dependent effects.

BackgroundParental genetics matters for childrens behavioural difficulties, but the extent to which this is due to direct genetic transmission versus environmentally mediated indirect genetic effects remains unclear. MethodsWe studied eight European birth cohorts with over 33,000 family-based trio samples. We analysed polygenic scores (PGSs) for 13 mental health and neurodevelopmental conditions and their composite indices (PC1 and mean) representing general neuropsychiatric liabilities, as well as educational attainment (EA) and alcohol and cigarette use, from children (PGSc), mothers (PGSm), and fathers. Child internalising, externalising, and total difficulties reported by mothers and/or fathers were examined at preschool and school ages. We then conducted multivariate meta-analyses to combine cohort-level results. FindingsWe observed several direct genetic effects on externalising difficulties, while indirect genetic influences were mainly identified for internalising difficulties. Specifically, child PGSs for attention-deficit/hyperactivity disorder (ADHD) and EA predicted higher and lower levels, respectively, of child externalising and total difficulties (all pFDR<0{middle dot}001; for school-aged externalising difficulties, PGSc-ADHD: {beta}=0{middle dot}121 [95% CI 0{middle dot}091 to 0{middle dot}151], pFDR<0{middle dot}0001; PGSc-EA: {beta}=-0{middle dot}095 [95% CI -0{middle dot}127 to -0{middle dot}063], pFDR<0{middle dot}0001), whereas maternal PGSs for major depressive disorder (MDD) and general neuropsychiatric liabilities were associated with internalising and total difficulties across parental raters and child ages (all pFDR<0{middle dot}05; for school-aged internalising difficulties, PGSm-MDD: {beta}=0{middle dot}049 [95% CI 0{middle dot}017 to 0{middle dot}081], pFDR=0{middle dot}016; PGSm-PC1: {beta}=0{middle dot}056 [95% CI 0{middle dot}022 to 0{middle dot}091], pFDR=0{middle dot}011). No statistically significant effects from paternal PGSs were identified. InterpretationIn this multi-cohort study, findings across multiple traits, raters, and ages supported several direct genetic effects of ADHD and EA on child externalising difficulties and indirect genetic effects on internalising difficulties, especially maternal depression and general neuropsychiatric liabilities. These suggest that child internalising difficulties are not solely driven by direct genetic transmission. More comprehensive research is needed to better understand the mechanisms involved, and ultimately how to ameliorate child behavioural difficulties. FundingEU, ERC, RCN, RCF, UKRI, SERI, DFG Research in contextO_ST_ABSEvidence before this studyC_ST_ABSIndirect genetic effects (IGEs) refer to the influence of parental genotypes on offspring outcomes beyond direct genetic effects (DGEs), for example via environmental pathways. While IGEs on offspring cognitive traits are well-established for educational attainment, evidence for IGEs of parental liabilities to mental health and neurodevelopmental conditions remains limited. To assess the current state of evidence, we conducted a systematic search of published studies applying trio-based polygenic score (PGS) designs to child and adolescent mental health outcomes. We identified 141 primary studies in MEDLINE, Embase, PsycInfo, and Web of Science, by 6 March 2025, after removing duplicates; following screening, 12 studies met inclusion criteria (see supplement for a full description including results). Ten out of the 12 studies focused on externalising outcomes, with little or inconsistent support for IGEs. When observed, IGEs were mainly driven by maternal liabilities to autism, educational attainment, and cognitive performance on child outcomes. The current evidence was too limited and heterogeneous to synthesize findings quantitatively, therefore a qualitative synthesis was conducted. Many studies were statistically underpowered, and the observed IGEs were in all cases sample-specific. There were no published multi-cohort studies. Added value of this studyWe integrated information across over 33,000 mother-father-child trios from eight European cohorts, investigating 18 PGSs from parents and children, using maternal and paternal ratings of offsprings internalising, externalising, and total difficulties as outcomes at both preschool and school age. We mainly observed DGEs on externalising difficulties, consistent with previous studies. Some evidence of IGEs was found for internalising and total difficulties. IGEs were often found to be maternally driven, with the most robust evidence across ages and raters emerging for maternal depression and general neuropsychiatric liabilities. Implications of all the available evidenceThe current evidence suggests that childrens behavioural difficulties, especially internalising difficulties, may be partly driven by the environment shaped by maternal neuropsychiatric liabilities. Ours and previous findings highlight a pressing need for more comprehensive studies across different cohorts, raters, outcomes, and time points to understand the true extent of IGEs in the intergenerational transmission of mental health.

BackgroundCommunity safety is a key determinant of mental well-being, yet racially and ethnically minoritised communities in the UK often face higher exposure to violence alongside barriers to formal protection and support. In these contexts, informal support networks may play a critical role in shaping how safety is experienced and how distress is managed. Although such networks are widely recognised as protective for mental well-being, there is limited qualitative research examining how they operate in relation to community safety in settings shaped by structural inequality. This study explores how informal support networks influence experiences of community safety and mental well-being among racially and ethnically minoritised groups in South East London. MethodsThis qualitative study draws on semi-structured interviews (n = 31) with racially and ethnically minoritised participants aged 16+ living or working in Lambeth and Southwark [South East London]. Using a co-produced qualitative design, community consultations informed the development of interview topics. Interviews explored informal support networks, experiences of community safety and their intersections with mental well-being. Audio-recorded interviews were transcribed verbatim and analysed using inductive thematic analysis. ResultsFour themes were identified: (1) experiences of community safety and their mental health impacts; (2) gendered experiences of safety and responsibility; (3) formal support and its barriers; and (4) community and peer-led initiatives as a response to institutional distrust. ConclusionInformal support networks are central to everyday safety and emotional well-being, yet they cannot substitute for adequately resourced, culturally informed public provisions. Strengthening public infrastructure must involve meaningful collaboration with trusted community networks and address the intersectional needs of racially and ethnically minoritised groups.

BackgroundSuicidal ideation (SI) fluctuates over time, yet traditional static risk factors poorly align with its dynamics over time. Understanding dynamic symptom patterns may advance knowledge of the temporal interplay between SI and co-occurring symptoms in adults with depressive and anxiety disorders. Materials and methodsWe analyzed six waves (at baseline, and after 2, 4, 6, 9, and 13 years of follow-up) of the Netherlands Study of Depression and Anxiety (NESDA; n = 305, mean age 40.8 years, 62% female) in participants with any SI fluctuation over time. Variables included depressive, anxiety, mastery, and worry symptoms. Dynamic Time Warping (DTW) quantified within-person temporal alignment between SI and other symptoms, and an undirected network and forestplot visualized co-fluctuations. Analyses were stratified by age-groups and sex. ResultsOver the years, SI co-fluctuated most strongly with affective and anhedonic depressive symptoms, including sad mood, low capacity for pleasure, low general interest, pessimism, quality of mood, and decreased appetite. Select anxiety (terrified/afraid) and worry (overwhelming worries) items also aligned with SI, whereas mastery items did not. Patterns were broadly consistent across age and gender subgroups. Networks indicated that SI is part of a cluster of depressogenic symptoms but bridges to acute fear and persistent worry. ConclusionsSI is a dynamic phenomenon closely linked to specific depressive, anxiety, and worry symptoms. Interventions targeting mood instability, anhedonia, and uncontrollable worry, combined with real-time monitoring, may improve personalized suicide prevention. DTW provides a framework to identify long-term temporally proximal symptom patterns.

BackgroundWhile growing evidence implicates sleep-wake and circadian rhythm disturbances (SCRDs) in the onset and course of mood and psychotic disorders, longitudinal studies using objective measures are limited. This clinical cohort study examined whether actigraphy-derived SCRDs (sleep duration, timing, and efficiency) predicted transition to (i) any full-threshold mental disorders; and then specifically: (ii) full-threshold bipolar or psychotic disorders or (iii) other full-threshold (i.e. depressive or anxiety) disorders, in youth accessing mental health care. MethodsActigraphy monitoring was completed for 5-23 days in 250 participants (aged 12-30) presenting to youth-focused early intervention services in Sydney, Australia. Participants were followed longitudinally as part of the Optymise cohort for 6+ months (up to 8 years; median 2.5 years). Logistic regression and Cox proportional hazard models estimated associations between SCRDs and illness progression, after controlling for relevant baseline clinical and demographic covariates (e.g., age, sex, social and occupational functioning, mania-like and psychotic-like experiences, medication use). ResultsLonger sleep duration at baseline predicted higher odds of transition (OR = 2.23 [95%CI = 1.38-3.74]), and shorter time-to-transition (HR = 2.05 [95%CI = 1.23-3.40]) to full-threshold bipolar or psychotic disorders. This effect remained significant after controlling for clinical covariates. Later sleep midpoint predicted transition to any full-threshold mental disorder (OR = 1.46 [95%CI = 1.02-2.17]) at the uncorrected significance level. ConclusionsExcessive sleep duration may represent an early marker of vulnerability for progression to severe mental illness. Findings support the prognostic utility of objective measures of SCRDs to guide indicated prevention and early intervention.

BackgroundIn 2020, Oregon became the first U.S. state to establish a regulated framework for adults to access psilocybin services using naturally-derived mushroom products. No studies have examined mental health outcomes among individuals receiving psilocybin in this context. AimsTo evaluate changes in self-reported symptoms of depression, anxiety, and well-being 30-days post-psilocybin session under the Oregon state-regulated model , and document session-related adverse events and doses consumed. MethodsThis was a naturalistic study (March 2024-April 2025) among adults [&ge;]21 years participating in a legal psilocybin services program. Online surveys were completed pre-session, 1-day, and 30-days post-session. Primary outcomes were change in depression, anxiety, and well-being symptoms pre-session to 30-days post-session evaluated using linear mixed-effects models (random effect: timepoint; fixed effects: sex, concurrent psychiatric medication use, age, session dose [total psilocybin equivalents, TPE, mg: psilocybin mg + 1.39 * psilocin mg]). Adverse events (e.g., hallucinogen persisting perception disorder [HPPD]) were assessed at 1-day and 30-days post-session. ResultsParticipants (n=88; median age 43 years; 52% male) were predominantly Oregon residents (53.4%), psychedelic-experienced (64.8%), and concurrently using psychiatric medication (46.6%). All outcomes improved significantly at 30-days post-session (p<0.001), including in sensitivity analyses stratified by concurrent psychiatric medication usage (p<0.001 all outcomes, both groups). Two participants (2.3%) reported symptoms consistent with HPPD at 1-day post-session, but none at 30-days. Mean dose was 27.8 mg (SD 8.2) TPE. ConclusionsPsilocybin sessions delivered under the Oregon regulatory model were associated with clinically meaningful improvements in depression, anxiety, and well-being 30-days post-session, supporting therapeutic effectiveness of legal psilocybin services.
