Autistic psychiatrists occupy a paradoxical position: trained to recognise and assess autism in others, yet navigating a professional culture in which their own autistic identity remains largely concealed. Despite growing visibility of autistic clinicians, the barriers autistic psychiatrists face to formal diagnosis and professional disclosure remain unexplored. This study used interpretive phenomenological analysis to examine the experiences of seven autistic psychiatrists in relation to diagnosis and disclosure. Data were generated through in-depth interviews and Retzinger's framework for identifying shame in discourse was applied as an analytical tool within the interpretive process. Shame emerged as the overarching theme across the dataset, operating through four group experiential themes. Its origins lay in childhood experiences of difference and perceived defectiveness, transmitted through family, peers, and the broader social environment. In professional life, shame was sustained and amplified by colleagues' misconceptions about autism, anticipated loss of credibility, and the deficit-based diagnostic criteria - which rendered self-recognition difficult and made formal diagnosis a perceived professional liability. Critically, shame did not only create barriers: it functioned as an override mechanism, rendering the known benefits of disclosure - to participants themselves, to colleagues, and to patients - insufficient to translate into action. This override function was not explained by fear of discrimination or rational career protection alone; it reflected shame's operation as an internal prohibition, dissociated from its original social source and persisting even where stigma had been intellectually processed and rejected. These findings reposition shame not as one barrier among many but as the organising force through which all barriers operate. Interventions aimed at increasing disclosure by raising awareness of its benefits misread the operative mechanism. Creating conditions in which autistic psychiatrists can make decisions about their identities freely requires naming and addressing shame - in research, in clinical training, and in the culture of psychiatry.

Purpose: Involuntary psychiatric hospitalization under court orders requires careful balancing of legal obligations and clinical needs. Identifying factors that influence the length of these hospital stays helps clarify the relationship between legal frameworks and psychiatric treatment. This study aims to describe the socio-demographic, clinical, and legal profiles of individuals hospitalized under court warrants and to identify factors independently associated with the duration of forensic hospitalization. Methods: A retrospective study was conducted on 119 patients discharged between 2018 and 2023. Data were collected from medical and legal records, including socio-demographic details, psychiatric diagnoses, offense types, hospital stay lengths, and legal proceedings. Results: Most patients were men (91.6%) diagnosed with schizophrenia or schizoaffective disorder (97.5%), with high rates of comorbid substance use disorder (79.0%) and unemployment (85.7%). The median hospital stay was 19.0 months, representing 40% of the maximum statutory sentence. Patients with low-severity offenses served a larger share of their maximum sentence (47%) than those with high-severity offenses (24%). Time to first discretionary leave was the strongest predictor of total stay duration in univariable analysis. Conclusion: The finding that patients with minor offenses have longer hospital stays than those with serious offenses confirms that clinical factors, rather than offense severity, primarily influence discharge decisions. These findings support moving toward personalized, clinically focused, and family-inclusive forensic discharge planning while maintaining public safety.

Introduction: In 2020, Oregon became the first US state to legalize state-regulated psilocybin services. This study aims to examine: 1) the clinical and demographic characteristics, 2) psilocybin use motivations, and 3) differences in preparedness among patients seeking care in a Oregon- based pilot consult service specializing in psilocybin risk reduction. Methods: This retrospective chart review abstracted sociodemographics, trauma history, and medical and psychiatric risks of patients (November 2023 - September 2025). The Psychedelic Preparedness Scale (PPS), a validated self-report questionnaire, measured preparedness. Two sample t-tests examined associations of PPS scores by insurance, consult motivations, and prior psychedelic use. Results: Patients (N=29) had a mean age of 47.14 years (SD=15.9), were majority female (55.2%); White (82.8%); and privately insured (62.1%). Patients mostly sought psilocybin to address only a psychiatric concern (75.9%); 27.6% anticipated naturalistic (non-state regulated) use. Most patients were deemed low risk for adverse events. Prevalence of prior challenging psychedelic experiences (CPE) was 17.2%; 58.6% reported lifetime psilocybin use. 86.2% endorsed >1 form of lifetime trauma. Of PPS completers (N=23, 79%), mean score was 91.3 (SD = 23.99). Scores did not significantly differ by insurance; consultation motivation; CPE; prior psilocybin or psychedelic use. Conclusion: Patients utilizing a novel consultation service demonstrate a high prevalence of trauma, prior psilocybin use, and baseline preparedness. While preliminary, this is among the first descriptions of patients seeking medical and psychiatric consultation when considering psilocybin and highlight the potential role of healthcare systems in providing evidence-based patient education and risk reduction as interest in psychedelics grows.

Objectives To explore caregiver and clinicians perspectives on implementing mental health conversations and supports for caregivers of children with chronic conditions in paediatric outpatient clinics. Specifically, views were sought on (a) screening approaches and measures (phase 1) and (b) how feedback and support could be provided to caregivers experiencing mental health difficulties (phase 2). Methods Caregivers and clinicians from two outpatient clinics (neuromuscular and diabetes) at a tertiary paediatric hospital in Melbourne, Australia participated in online focus groups in July and August 2024. Caregivers were recruited from outpatient clinics and clinicians were recruited via email. Both groups were combined for phase 1 before separating into breakout rooms for phase 2. Two authors conducted reflexive thematic analysis of transcripts using NVivo. Results Sixteen participants (caregivers n = 8; and clinicians n = 8) took part in in two semi-structured focus groups. Analysis generated two overarching domains, each comprising multiple themes. Domain 1, Addressing caregiver mental health, captured themes of overwhelm and invisibility, diverse caregiving roles, and the need for time and resources to support wellbeing conversations. Domain 2, Housing the mental health conversation, encompassed themes of screening preferences, caregiver agency in confidentiality, delivery of feedback, and access to tailored supports. Conclusions Caregivers and clinicians support routine caregiver mental health discussions in paediatric outpatient settings. Caregivers favour screening at diagnosis and key transitions, with clear, and actionable feedback delivered away from the child. Questions about record-keeping warrant further exploration, as do the perspectives of fathers.

Abstract Background To estimate the frequency of likely, often undiagnosed autism and attention deficit hyperactivity disorder (ADHD) in UK adults of working age (18-66 years) who are not in education, employment, or training (NEET), and to examine whether neurodivergent traits are associated with NEET status directly and indirectly via health burden and educational attainment. Design Frequency-matched online case-control study. Setting UK general population, recruited via online research platform Prolific. Participants Six hundred adults of working age (18-66 years); 300 NEET, 300 in education, employment, or training (EET) matched at the marginal level on age, sex assigned at birth, and ethnicity. Primary and secondary outcome measures Autistic traits (Ritvo Autism and Asperger Diagnostic Scale-14, RAADS 14) and ADHD traits (Adult ADHD Self Report Scale, ASRS 5) indexed likely autism and ADHD (cut off [≥]14 on each). Physical and mental health conditions were self reported and aggregated into composite indices of health burden. NEET status was the primary outcome; educational attainment and health burden were tested as parallel mediators of the association between neurodivergent traits and NEET status. Results NEET participants screened positive more frequently for likely autism (66.3% vs 49.0%; OR 2.05, 95% CI 1.48 to 2.85) and likely ADHD (34.3% vs 26.0%; OR 1.46, 95% CI 1.03 to 2.08) than EET participants, despite identical existing formal diagnosis rates. Physical (OR 2.00, 95% CI 1.38 to 2.90) and mental (OR 2.57, 95% CI 1.80 to 3.68) health conditions were also associated with higher odds of NEET status. In mediation analyses, neurodivergent traits predicted NEET status both directly (OR 1.33, 95% CI 1.13 to 1.68) and indirectly via greater health burden (indirect OR 1.13, 95% CI 1.02 to 1.35) and lower educational attainment (indirect OR 1.08, 95% CI 1.03 to 1.15). Conclusion NEET adults showed a marked excess of autism and ADHD traits, alongside elevated physical and mental health burden and lower educational attainment. Earlier recognition of neurodivergent traits, proactive provision of equitable requirements in education and employment, and integrated physical and mental health support may reduce NEET risk in this population. This has considerable implications for policy and practice in health, education, and wider society.

Autistic individuals may be at an increased risk of hazardous drinking compared to non-autistic counterparts: potential motivations include facilitated social interactions and self-medication of co-occurring difficulties, and possible risk factors include being older and female. However, research remains limited and centred around clinical samples. Given the diversity of the autistic community, it is important to understand the intricacies of alcohol use to inform appropriate support. Eighteen autistic adults took part in semi-structured interviews about their drinking experiences. Data were analysed using reflexive thematic analysis. Three main themes were created (Autistic experiences, Managing expectations and coping by drinking and Recommendations for support). Autistic experiences was used to denote the ways in which participants described their own autistic features influenced their relationship with alcohol. Managing expectations and coping by drinking was chosen to reflect the pressures felt by participants to show up in social relationships and the co-occurring difficulties many of them managed using alcohol. Therapeutic preferences for alcohol services were captured under Recommendations for support. As expected, participants used alcohol to facilitate social interactions and self-medicate. However, additional nuances uncovered may provide clinical utility and highlight the need for further research in other demographics within the community.

People experiencing mental health problems often encounter fragmented systems of care in which physical and mental health needs are addressed separately. Physical activity is an evidence-based approach for improving both physical and mental health and integrating evidence-based psychosocial support with physical activity in community settings may offer a holistic and accessible approach. This study explored interest-holder perspectives on integrating the World Health Organization Doing What Matters in Times of Stress intervention within a trauma-informed, community-based physical activity service. A qualitative study was conducted within a free, community-based, university-run physical activity service in Sydney, Australia. Semi-structured interviews were undertaken with people with lived expertise of mental health challenges, Clinical Exercise Professionals, and mental health service providers. Data were analysed using thematic analysis guided by the Consolidated Framework for Implementation Research. Nineteen participants (11 people with lived expertise, four Clinical Exercise Professionals, and four service providers) took part. Participants generally viewed the future delivery of Doing What Matters in Times of Stress by exercise professionals as acceptable and potentially beneficial for supporting both mental and physical health. Existing rapport with exercise professionals, the disarming nature of physical activity, and practical stress-management strategies were identified as strengths of the model of future delivery. Participants viewed Clinical Exercise Professionals as potentially well-placed to facilitate Doing What Matters in Times of Stress alongside supervised physical activity, as long as it was supported by appropriate training, supervision, referral pathways, and clear professional boundaries. Trauma-informed, inclusive environments, tailoring the intervention, prioritizing service user choice and organisational support were also considered important factors for successful future implementation. Conclusions: Integrating Doing What Matters in Times of Stress within a trusted, community-based physical activity service was perceived as acceptable and potentially meaningful for people experiencing mental health challenges. Findings warrant further piloting and evaluation of integrated physical activity and psychosocial intervention models.

Background: Trauma-informed approaches (TIAs) are increasingly implemented across public-sector settings to improve support for young people affected by adverse childhood experiences (ACEs). However, practitioners often report difficulties translating broad trauma-informed principles into everyday practice, and young people are rarely involved in developing resources intended to support implementation. Aim: To co-design, implement and undertake a preliminary evaluation of a youth-led trauma-informed resource for professionals working with young people in public-sector settings in England. Methods: The study formed part of the UKRI-funded Attune programme and employed Accelerated Experience-Based Co-Design (AEBCD). Eighteen adolescents with lived experience of ACEs and 16 professionals from nine public-sector settings participated in three regional co-design workshops. Findings from a prior arts-based lived experience study informed the workshops. Participants collaboratively developed Validating Voices, a low-cost resource designed to increase validating interactions between professionals and young people. The resource was subsequently introduced into nine organisations and evaluated using staff surveys and semi-structured interviews. Results: Co-design participants identified professional invalidation of young peoples experiences, identities, needs and emotions as an under-recognised contributor to mental health. The resulting resource combined discussion cards, creative activities, role-play and organisational reflection exercises to promote validating practices. Five organisations implemented the resource and reported it to be feasible. Flexible local adaptation was common, while more participatory role-play elements proved harder to implement consistently. Staff observed increased opportunities for disclosure, reflection, peer connection and professional curiosity about young peoples experiences. Staff reported listening differently to young people and, in some settings, implementing changes in response to young people's recommendations. Conclusions: Youth-led co-design identified validation as a practical and meaningful mechanism for operationalising trauma-informed principles in everyday professional practice. With refinements, Validating Voices shows promise as a resource to support more relational, collaborative and trauma-informed responses to young people in public sector settings.

Objectives To identify research priorities for improving the mental health of neurodivergent higher education (HE) students by exploring the perspectives of individuals with lived experience. Design Qualitative study using an online survey. Data was analysed using a deductive-inductive, hybrid semantic thematic analysis. Setting UK higher education institutions. Participants 104 current and former neurodivergent HE students with diverse neurodivergent profiles and intersecting identities. Main outcome measures Participant recommendations regarding priorities for future research on neurodivergent student mental health. Results Six themes were identified and were grouped into (1) general recommendations for research and (2) recommendations specific to neurodivergence within a HE context. Participants prioritised a shift away from medical model approaches towards research informed by social and strengths-based perspectives. Key priorities included improving understanding of diagnostic barriers and misdiagnosis, reducing stigma, investigating institutional barriers within HE, evaluating the effectiveness of support and accommodations and examining the experiences of underrepresented and intersectional groups. Participants emphasised the need for research on more flexible teaching practices, sensory-friendly learning environments, integrated mental health and educational support and alternatives to diagnosis-dependent access to services. Conclusions Future research should move beyond descriptive accounts towards evaluating interventions and current support provision to understand if they improve the mental health of neurodivergent students. Adopting intersectional approaches, moving beyond binary deficit- or strengths-based frameworks and focusing on inclusive, needs-based support rather than diagnosis-led systems are likely to produce more equitable and effective outcomes for neurodivergent students in higher education.

Post-traumatic stress disorder (PTSD) is associated with high rates of comorbid personality disorders, which may contribute to PTSD severity. Among veterans with PTSD, obsessive compulsive personality disorder (OCPD) is common, with reported prevalence estimates ranging from 7-44%. Despite this, the relationship between OCPD traits and PTSD severity remains poorly understood. This retrospective, cross-sectional study examined associations between PTSD severity and OCPD traits in a naturalistic sample of 99 Veterans evaluated by a single clinician in a PTSD/Trauma Recovery Services clinic. PTSD symptoms were measured with the PTSD Checklist for DSM-V (PCL-5), and OCPD traits were measured with the Pathological Obsessive-Compulsive Personality Scale (POPS). Relationships between these two constructs were examined using Pearson correlations. Overall PTSD severity was significantly and positively correlated with total OCPD traits (r = 0.46, p < 0.001). Among OCPD domains, maladaptive perfectionism showed the strongest association with PTSD severity (r = 0.44, p <.001), followed by emotional overcontrol and reluctance to delegate (both r = .38, p < .01), rigidity (r = .35, p < .01), and difficulty with change (r = .28, p < .05). These findings suggest OCPD traits impact PTSD symptom burden in veterans, warranting further research and clinical attention.

Background Children of parents with schizophrenia (SZ) or bipolar disorder (BP) show elevated rates of mental disorders. Longitudinal studies comparing offspring at familial risk with the background population are lacking. Method This study is an eight-year follow-up of the Danish High Risk and Resilience study. We examined four-year prevalence from age 11 to age15 (n=416), cumulative incidence by age 15 (n=516), persistency of mental disorders from age 11to age 15 (n=396) and global functioning in 15-year-old adolescents with familial high risk of SZ (FHR-SZ) or BP (FHR-BP) compared to population-based controls (PBC). We assessed mental disorders and global functioning with the Kiddie Schedule for Affective Disorders and Schizophrenia - Present and Lifetime Version (K-SADS-PL) and the Childrens Global Assessment Scale (CGAS). Results Four-year prevalence of any mental disorder was higher in FHR-SZ (51.3%, OR=2.39, 95% CI 1.49-3.83) and FHR-BP (45.9%, OR=1.98, 95% CI 1.16-3.37) compared with PBC (30.5%). Cumulative incidence of mental disorders by age 15 was higher in FHR-SZ (67.2%, OR=3.19, 95% CI 2.11-4.82) and FHR-BP (64.4%, OR=2.82, 95% CI 1.75-4.54) than in PBC (39.1%). Adolescents with FHR-SZ showed the highest rate of persistent mental disorders (33.3%), followed by FHR-BP (24.5%), and PBC the lowest (12.9%). Global functioning at age 15 was lower in FHR-SZ than in both FHR-BP and PBC, and FHR-BP showed lower scores compared with PBC. Between-group differences in cumulative incidences of mental disorders and in global functioning scores remained stable across ages 7,11 and 15. Conclusion Adolescents at FHR-SZ or FHR-BP show elevated risks of a range of mental disorders, psychiatric comorbidity, and lower global functioning from childhood to mid-adolescence, not confined to the disorders for which they carry familial risk. This vulnerability underscores the need for early detection and support for FHR offspring and their families.

Introduction: Auditory verbal hallucinations (AVH) affect 60-80% of people with schizophrenia, yet existing assessment tools inadequately capture their phenomenological complexity. Aim: To determine whether individuals with schizophrenia spectrum disorders could accurately match auditory verbal hallucination loudness to an external audio track, and to explore participant perspectives on this approach. Methods: Eight participants with schizophrenia spectrum disorders and active AVHs rated loudness via a Likert scale and by adjusting a headphone audio track to match their experience. Structured interviews and thematic analysis captured participant viewpoints. Results: No significant correlation was found between audio tool and Likert scale scores. Seven of eight participants reported the audio tool provided greater precision in quantifying AVH loudness and better enabled them to convey their internal experience to others. Discussion: Audio-matching tools may offer meaningful advantages over traditional scales for quantifying AVH loudness, even where statistical convergence with existing measures is absent. Limitations: Small sample size; loudness alone cannot fully capture the qualitative experience of hearing voices. Implications: This tool shows promise for longitudinal tracking of AVH loudness. Recommendations: Further investigation of digital approaches to AVH assessment is warranted.

Background Psychiatric comorbidities commonly have a negative impact on epilepsy outcomes. However, they are continuously ignored in routine epilepsy care, with focus directed more towards seizure control. There is paucity of data on the burden of psychiatric morbidity among those living with epilepsy in Kenya. This study sought to determine the prevalence and associated factors of psychiatric morbidity among patients living with epilepsy at a tertiary referral hospital in Western Kenya. Methods This was a descriptive cross-sectional study. Consecutive sampling was used to recruit participants, with a sample size of 278. Data were collected using a structured pretested sociodemographic and clinical characteristics questionnaire, and the Mini International Neuropsychiatric Interview (MINI), and analyzed using STATA version 16. Pearson Chi-square test/Fishers Exact test and logistic regression were used to assess relationships at bivariate and multivariate levels respectively. Results The prevalence of psychiatric morbidity was 52.2%. Major depressive disorder was the most prevalent (36%), followed by anxiety disorders (26.2%), psychotic disorders (16.9%), and suicidality (15.1%). Casual/self-employment (aOR=2.590, p=0.020), seizure-related physical trauma (aOR=4.032, p=0.004), antiepileptic polytherapy (aOR=4.280, p=0.001), frequent seizures (aOR=3.801, p<0.001), and comorbid medical conditions (aOR=5.478, p=0.047) were independent predictors of psychiatric morbidity. Having attained a tertiary level of education was protective against psychiatric morbidity (aOR=0.221, p=0.036). Conclusion More than half of the patients living with epilepsy had at least one psychiatric comorbidity. Routine psychiatric screening and integration of mental health services in epilepsy care is essential to improve clinical outcomes.

Predicting real-world functional outcomes in schizophrenia (SCZ) remains a clinical priority, but existing models are limited by methodological constraints and a lack of established clinical utility. Cognition is a commonly used predictor, and the Normative Latent Cognitive Structure (N-LCS) approach provides a structure-informed representation that may address limitations of conventional domain-level scores. Data from two merged COBRE cohorts (163 SCZ, 180 healthy controls) were used to develop ridge regression models for economic (EF), occupational (OF), and social (SF) functioning, using N-LCS deviation metrics alongside a priori selected demographic and clinical predictors. Score-based models using MCCB domain T-scores were developed for comparison. Performance was evaluated using bootstrap-corrected AUC, balanced accuracy, and calibration for binary outcomes, and weighted kappa and log-loss for SF. Decision curve analysis (DCA) was used to assess clinical utility for the binary outcomes. The EF model achieved a corrected AUC of 0.76 and balanced accuracy of 0.73. The OF model achieved 0.72 and 0.71, respectively. The SF model showed modest performance (weighted kappa = 0.33). DCA indicated net benefit across the full threshold range for EF and above 0.37 for OF. N-LCS models demonstrated comparable or modestly superior performance to score-based models while using fewer predictors and showing better calibration for EF. These findings support the predictive utility of N-LCS for functional outcomes in SCZ and underscore the need for external validation in independent cohorts as a next step toward clinical application.

Background: In the UK, over 36 million contacts are made annually by people living with dementia (PLWD) to either primary or secondary community mental health services. As dementia progresses, PLWD may experience increased distress and resort to 999 calls for an ambulance, which may in turn result in conveyance to Accident & Emergency (A&E). Nearly 1 million A&E attendances are made by PLWD. This trend is set to rise sharply as the prevalence rates of dementia increase over time and as the condition progresses, with associated healthcare costs impacting overall care delivery. This may lead to reduced resource allocation for dementia emergency services, negatively affecting the experiences of both providers and service users. Aim(s): To explore ways to improve access and quality of care to emergency crisis care for PLWD from the perspective of healthcare staff providing this type of support. Methods: This qualitative study explored (1) the experiences, resources, and needs of healthcare professionals in emergency and community settings to support access for PLWD, and (2) the mechanisms influencing dementia crisis response. The COREQ Checklist was used to improve transparency, credibility, and reproducibility. Inter-rater reliability was calculated. PPIE contributors co-developed recommendations for healthcare professionals, and study findings informed a comic-based dissemination resource shared with third-sector organisations to support community awareness and engagement. Results: Fifteen interviews were held with emergency services staff. Inter-rater reliability was substantial between two raters (k = 0.62). Four overarching themes, with associated subthemes, were identified relating to crisis care delivery, barriers to effective response, and strategies employed to address these challenges. Additional themes captured decision-making processes at key points in the care pathway, including initial crisis response, during intervention, and at discharge from emergency and community services. Decision-making was characterised by the need to balance patient safety with autonomy in determining care in the best interests of PLWD and their informal carers. Discussion: This exploratory study reveals frontline staff perspectives on challenges and actionable strategies for dementia crisis care. Findings support targeted service improvements, cross-sector collaboration, and co-produced resources to enhance outcomes for PLWD and their informal carers.

Background Evidence on factors associated with cannabis for medical purposes (CMP) authorizations among Veterans Affairs Canada (VAC) clients remains limited and inconsistent, particularly concerning mental health and posttraumatic stress disorder (PTSD), a leading indication for use. We investigated demographic, clinical and service characteristics associated with VAC authorizations for CMP reimbursement. Method We linked VAC administrative CMP program data with responses from the 2019 Life After Services Studies cross-sectional survey of Regular Force veterans released between 1998 and 2018. Multivariable logistic regressions examined associations between CMP reimbursement (yes/no) and demographic, clinical and well-being factors, with analyses stratified by PTSD status. Results Among 1,289 respondents (weighted n=33,131), 18.4% were authorized for CMP reimbursement. Younger age (<40 vs. [&ge;]60 years: OR 4.78, 95% CI: 2.24-10.21), unemployment with inability to work vs. employed (OR 3.10, 95% CI: 1.78-5.40), land service vs. air (OR 2.07, 95% CI: 1.22-3.50), PTSD (OR 2.81, 95% CI: 1.69-4.66), anxiety (OR 2.32, 95% CI: 1.45-3.70), and severe pain vs. no pain (OR 3.61, 95% CI: 1.97-6.60) were independently associated with authorization. Unemployment and severe pain were consistent correlates across PTSD strata. Among those without PTSD, younger age, multiple physical conditions, and frequent mental health visits were significant; among those with PTSD, shorter service, witnessing destruction, and suicidal ideation were additional factors. Conclusions CMP authorization patterns among Canadian veterans reflect the intersection of mental health, pain, and functional impairment, with variation by PTSD status. These findings underscore the need for longitudinal research on CMP mechanisms, effectiveness and safety.

Lithium has been the gold standard for the treatment and prevention of relapse in bipolar disorder for over 60 years. Guidance from the National Institute for Health and Clinical Excellence states explicitly to 'offer lithium as a first-line, long-term pharmacological treatment for bipolar disorder'. Yet, in the last two decades its use has been in decline with clinicians favouring anticonvulsants or antipsychotics when treating this condition. In this study, we have used three openly available datasets containing prescribing data from primary and secondary care to explore trends in the use of lithium in England, showing both regional and temporal variance between 2015-2024. We have shown that lithium use declined in primary care by 20.9% in the last ten years (2015-2024) and 10.9% overall in the last five years (2019 to 2025). We have also shown how there is some regional variation in the source of lithium for patients, although the vast majority is prescribed in primary care. Further research into clinical behaviour is needed to understand what is driving the decrease in lithium usage, and what barriers and enablers may influence its use across the country.

Oregon (OR) and Colorado (CO) were the first states to enact regulations for provision of psilocybin with support of licensed "facilitators." As more states and countries adopt similar policies, informed public policy decisions require that client characteristics and rationale for using psilocybin, psilocybin dosing practices, mental health outcomes, and adverse events are understood. We performed a retrospective observational study of responses for 2363 individuals receiving psilocybin at OR and CO regulated service centers. Clients and facilitators entered data before and after receiving psilocybin, including the Mystical Experience Questionnaire-30 (MEQ-30), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and World Health Organization Well-Being Index-5 (WHO-5). Preexisting mental health issues were common (66%) in participants. Psilocybin doses ranged from 1-95 mg, with a mean total of 28*8 mg. We observed improvements of 49% in PHQ-9 scores, 51% in GAD-7 scores, and 22% in WHO-5 scores at two-weeks after dosing. MEQ-30 scores were dose-dependent. Changes in PHQ-9 and GAD-7 scores were not different for psilocybin doses [&le;]30 mg and >30 mg, and only weakly correlated with MEQ-30 scores. There were 94 mild adverse events during and after dosing, five more serious events not clearly related to treatment, and evidence of possible risk of increased suicidality. Study limitations include open label administration, self-reporting, loss of participants for follow-up, and a short 2-week post-dosing end-point. We conclude that psilocybin services, delivered within these regulated frameworks, is associated with improvements in mental health in real world populations, however, more robust monitoring is needed to ensure safety.

One-to-one peer support is widely used in mental health services, but the components associated with better outcomes remain unclear. We systematically reviewed randomised controlled trials and conducted additive component network meta-analyses to identify which components of one-to-one peer support worker interventions were associated with outcomes for adults using mental health services. CINAHL Ultimate, Embase, MEDLINE, PsycINFO, CENTRAL, ClinicalTrials.gov and ISRCTN were searched, supplemented by citation tracking, previous reviews and expert consultation. Interventions were coded for seven components: Training and development, Maintaining peer support worker wellbeing, Relationship-building, Social support, Emotional support, Practical support and Cultural adaptation. The review followed PRISMA-NMA reporting guidance and was registered with PROSPERO (CRD42022355291). Thirty-six trials randomised 6,645 participants across nine countries. Only quality of life and recovery yielded estimable component effects at one or more follow-up points. For quality of life, Practical support had a positive incremental estimate at 3 months (standardised mean difference 0.52, 95% confidence interval 0.17 to 0.87); no component showed clear evidence of benefit at 6 months; and at 12 months Social support had a positive estimate (1.57, 0.12 to 3.01), whereas Maintaining peer support worker wellbeing had a negative estimate (-1.66, -3.05 to -0.28). These estimates were not consistent across follow-up points. For recovery, Relationship-building had positive estimates at 6 months (0.90, 0.03 to 1.78) and 12 months (0.50, 0.29 to 0.72). Networks were sparse and often disconnected, and additivity could not be tested in disconnected networks. Current trials do not permit definitive prioritisation of peer-support components. Relationship-building was the most consistent candidate component, but all findings remain provisional. Future trials should prospectively specify, manipulate and measure component delivery.

Population-based studies of common mental health conditions (anxiety, depression, post-traumatic stress disorder) require measures that are valid in the study context. We set out to validate the Generalised Anxiety Disorder-7 scale (GAD-7), Patient Health Questionnaire-9 (PHQ-9); and Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) in the most widely spoken languages in Malawi (Chichewa and Chitumbuka). We undertook translation, adaptation, and piloting to produce final versions in both languages. We conducted criterion validation of the GAD-7, PHQ-9 and PC-PTSD-5 against reference diagnoses of DSM-5 generalised anxiety disorder, major/minor depressive episode, and PTSD respectively, using the Structured Clinical Interview for DSM-5 (SCID-5). A weighted sample of screened participants had SCID interview and this was adjusted for in the analysis. We recruited convenience samples of women and men from two sites: a rural Chitumbuka-speaking site where 342 were screened and 219 had SCID; and an urban Chichewa-speaking site where 458 were screened and 251 had SCID. In both languages, the measures had acceptable internal consistency (Cronbachs alpha [&ge;] 0.75). Regarding convergent validity, PHQ-9 and GAD-7 were highly correlated but PC-PTSD-5 was only weakly/moderately correlated with the other measures. In Confirmatory Factor Analysis, best fit for GAD-7 and PC-PTSD-5 was a 1-factor structure, and for PHQ-9 was a 2-factor structure; there was only partial measurement invariance between the 2 language versions of each measure. Area under the ROC curve (AUC) for GAD-7 detection of generalised anxiety disorder was: Chitumbuka 0.759 (95%CI: 0.634, 0.871); Chichewa 0.868 (95%CI: 0.812, 0.915). AUC for PHQ-9 detection of major depression was: Chitumbuka 0.634 (95%CI: 0.441, 0.869); Chichewa 0.843 (95%CI: 0.721, 0.927). AUC for PHQ-9 detection of minor-or-major depression was: Chitumbuka 0.751 (95%CI: 0.619, 0.865); Chichewa 0.801 (95%CI: 0.714, 0.879). AUC for PC-PTSD-5 detection of PTSD was: Chitumbuka 0.682 (95%CI: 0.519, 0.853); Chichewa 0.741 (95%CI: 0.604, 0.859). In conclusion, GAD-7 and PHQ-9 showed good/acceptable validity, although criterion validity of PHQ-9 for major depression in Chitumbuka was poor. PC-PTSD-5 showed limitations to its validity, indicating need for further development of PTSD measures in Malawi.
