BackgroundWhile commonly accepted depressive subtypes reflect phenotypic differences, there has been minimal progress in identifying discrete pathophysiological pathways, biomarkers or differential therapeutic approaches which effectively guide clinical management. AimsTo test the biological validity and clinical utility of a circadian subtype of depression on the basis of clinical course, differential medication response (self-reported) and genetic risk profile. MethodsCross-sectional data we...

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 fact...

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,...

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 req...

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...

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 r...

Depression is a heterogeneous disorder, often diagnosed based on symptom co-occurrence. However, individuals may present with markedly different symptom profiles, potentially reflecting distinct underlying mechanisms. Identifying common patterns of symptoms using data-driven approaches could help clarify the heterogeneity of depression. Furthermore, examining the sociodemographic and lifestyle characteristics, health status, and polygenic scores of individuals with specific symptom profiles may ...

Background At present, there are no approved pharmacological treatments for people at clinical high risk for psychosis (CHR-P). We sought to assess the acceptability of cannabidiol (CBD): a promising candidate treatment for this population. Methods CHR-P individuals completed a survey which assessed their views on the acceptability of CBD, its expected effectiveness and side effects, and on formulation preferences. Results The sample comprised 55 CHR-P individuals (24.3 years and 69% female). Mo...

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 ...

ObjectivesElectroconvulsive Therapy (ECT) is an effective treatment for bipolar disorder, particularly in severe acute cases or for illness resistant to pharmacotherapy. However, the risk of relapse following ECT is high, necessitating intervention to reduce this risk. Based on findings from ECT studies in unipolar depression and its well-known mood-stabilizing properties, it is likely that lithium treatment may reduce the risk of relapse of bipolar disorder following ECT. Therefore, we conduct...

BackgroundEarly detection of individuals at risk for clinical deterioration in first-episode psychosis (FEP) remains a vital challenge in psychiatric care. Emerging evidence indicates that immune dysregulation might play a crucial role in the pathophysiology and progression of psychotic disorders. AimsThis study examined the predictive potential of a plasma cytokine and chemokine panel in anticipating clinical stage transition of FEP patients. MethodUsing multiplex immunoassays, plasma samples...

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 consum...

IntroductionSepsis is a life-threatening ailment caused by an exaggerated immune response to infection that poses a major health problem, with increasing prevalence, high costs, and poor outcomes. Improved outcomes are seen in patients when providers follow the Surviving Sepsis Campaign recommended clinical practice guidelines for identifying and treating sepsis using a 3-hour and 6-hour bundle after sepsis is suspected. Previous research has shown patients with mental health issues receive wors...

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 childbir...

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 ...

IntroductionDepression is highly prevalent among young adults worldwide. While research links health behaviours, such as dietary intake, to depression, few studies have examined these associations among young adults in low- and middle-income countries, including South Africa. This study investigated whether dietary intake was associated with an increased risk of depression in a cohort of young South African adults, aged 20-30 years, as part of the Global burden of disease Lifestyle And mental Di...

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. de...

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 ...

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 re...

ImportanceLarge language models (LLMs) have demonstrated diagnostic potential in several medical specialties, but their application to psychiatry - where diagnosis relies heavily on clinical judgment, narrative interpretation, and reasoning under uncertainty - remains insufficiently evaluated. ObjectiveTo evaluate diagnostic accuracy and clinician-judged reasoning quality of multiple large language models using psychiatric case vignettes. DesignMixed-methods evaluation study of diagnostic accu...
