This umbrella review synthesizes data on the prevalence of mental disorder symptoms among university students worldwide. A systematic search of seven databases (inception-July 23, 2023) followed PRISMA guidelines. We included meta-analyses assessing the prevalence of mental disorder symptoms, evaluating methodological quality with AMSTAR-2. A random-effects meta-analysis was conducted, along with meta-regression and subgroup analyses for moderators (percentage of females, publication date, healthcare-related degrees, COVID-19 pandemic). We included 1,655 primary studies from 62 meta-analyses, encompassing 8,706,185 participants. AMSTAR-2 ratings classified 35 % of meta-analyses as low quality and 65 % as critically low. Pooled prevalence estimates were: depression-mild (35.41 %, CI=33.9-36.93) and severe (13.42 %, CI=8.03-19.92; k=952; n=2,108,813); anxiety-mild (40.21 %, CI=37.39-43.07) and severe (16.79 %, CI=7.21-29.29; k=433; n=1,579,780); sleep disorders (41.09 %, CI=35.7-46.58); eating disorders (17.94 %, CI=15.79-20.20); gambling disorder (6.59 %, CI=5.52-7.75); post-traumatic stress disorder (25.13 %, CI=20.55-30.02); stress (36.34 %, CI=29.36-43.62); and suicide-related outcomes (ideation past 12 months: 10.76 %, CI=9.53-12.06; lifetime ideation: 20.33 %, CI=16.15-24.86; suicide attempt past 12 months: 1.37 %, CI=0.67-2.29; lifetime attempt: 3.44 %, CI=2.48-4.54). Meta-regression analyses identified statistically significant moderators of prevalence such as healthcare academic degrees and the pandemic in the case of depression and studies with more females in the case of sleep disorders. This is the most comprehensive synthesis on the prevalence of mental disorder symptoms in university students, providing crucial insights for clinicians, policymakers, and stakeholders.

BACKGROUND:) that underlies the vulnerability to both physical and mental conditions could have important implications for our approach to health assessment and treatment. OBJECTIVE:in children and adolescents. METHODS:This Swedish registry-based cross-sectional study included children and adolescents born between 1996 and 2003 with follow-up until 2013. We extracted data on 25 mental and physical health conditions according to the ICD-10 system. To determine the optimal dimensional structure of these conditions, several competing measurement models were tested, including correlated factors, one factor, various bifactor specifications and bifactor exploratory structural equation modelling (ESEM). FINDINGS/RESULTS:=0.423; ECV=0.130) factors also indicated additional significant unique contributions. CONCLUSIONS:underlying both mental and physical conditions, alongside distinct domain-specific factors. These findings have important implications for clinical practice, providing evidence that suggests the need for more integrated approaches to health assessment and treatment that consider the interconnectedness of mental and physical health.

Children and adolescents with autism spectrum disorder and/or an intellectual disability (ASD/ID) are psychiatrically hospitalized at disproportionately higher rates than youth without ASD/ID. Despite this, few studies have compared the clinical courses of youth with and without ASD/ID in inpatient (IP) child and adolescent psychiatry (CAP) settings. This study used a cross-sectional design of all youth (M = 14.0 years, SD = 2.6 years) admitted to an urban IP unit between 2018 and 2021 to examine differences between ASD/ID and non-ASD/ID youth across dimensions of sociodemographic and psychiatric history and clinical course. 1101 Patients were included in the study and 170 (15.4%) had a history of ASD/ID. ASD/ID youth were more likely to be younger, be male, have histories of violence, and on average have more prior hospitalizations and existing psychotropic prescriptions than their non-ASD/ID counterparts. ASD/ID youth were less likely than their non-ASD/ID peers to be admitted for suicidality and more likely to be admitted for aggression; they had longer average lengths of stay, received more IP emergency medications for agitation, and experienced greater polypharmacy at discharge. The IP psychiatric clinical course of ASD/ID youth differs from that of non-ASD/ID youth, suggesting that ASD/ID youth often present to IP settings with externalizing symptoms. Findings highlight the importance of clinical strategies tailored to the unique needs of ASD/ID youth to improve their care in general IP CAP settings.

AIM/UNASSIGNED:(prolonged social isolation), and how they formulate and treat such cases. METHODS/UNASSIGNED:case vignette was sent to psychiatrists of 34 countries around the world. Participants rated for the vignette: frequency of similar cases in one's practicing country; and aspects of formulation, diagnosis, suicide risk, and treatment plan. RESULTS/UNASSIGNED:In total, 344 complete responses from 34 countries were returned. Eight countries/areas had 10 or more respondents: Japan (61), South Korea (54), Nepal (48), Iran (40), Thailand (32), India (23), Hong Kong (12), and UK (10); the remainder were placed in the "others" group (64). Respondents from all countries except Thailand felt that similar cases were seen. Diverse patterns of response were obtained regarding formulation and treatment. Japan, South Korea, and "others" favored psychosocial aspects in the formulation, while Iran, Nepal, and India favored biological factors. Most respondents felt the case could be treated by an outpatient visit, while others preferred hospitalization. Psychotherapy was rated highly as an intervention; Iran, South Korea, and "others" also rated pharmacotherapy highly. CONCLUSION/UNASSIGNED:patients.

Parental support and acceptance are strong protective factors for better mental health outcomes among transgender and gender diverse youth. Psychological inflexibility, specifically in the role of parenting, or "parenting inflexibility", refers to an over-reliance on avoidance strategies at the expense of parenting values. Parenting inflexibility may be related to parental support, making it a useful target of intervention for parents of transgender youth. The aim of the present study was to develop a brief clinically useful measure of parenting inflexibility based on a synthesis of existing measures and to evaluate the psychometric properties across two study populations. Study 1 used exploratory factor analysis to examine this measure among parents in the general population recruited using MTurk. Study 2 used confirmatory factor analysis to examine the measure among parents of transgender youth recruited from a clinic. The final measure, the Impact of Parenting Avoidance (IPA) scale, is a one-factor 7-item measure of parenting inflexibility that is easy to administer and interpret in a pediatric health setting. The resulting measure demonstrated acceptable reliability, and it was significantly correlated with important outcome variables, such as negative parenting practices and lower perceived parental support among transgender and gender diverse youth.

Parental reflective functioning (PRF) refers to a parent's ability to understand their own and their child's mental states and connect them to behaviors. This longitudinal study evaluated (1) associations among prenatal PRF, using the Pregnancy Interview, demographics, prenatal maternal depressive symptoms, and maternal-fetal attachment and (2) whether prenatal PRF predicted parenting quality assessed during unstructured and challenging mother-child interaction tasks beyond infancy, after controlling for cumulative risk. Data were collected in an urban community sample of women in the midwestern US. Prenatal PRF was positively associated with maternal educational attainment and negatively associated with cumulative demographic risk, but not with depressive symptoms or maternal-fetal attachment. Controlling for cumulative risk, hierarchical regressions showed that prenatal PRF was the sole significant predictor of positive parenting at 36 months, observed during a challenging teaching task but not during free play. Prenatal PRF did not predict negative parenting. These patterns persisted when analyses were repeated within a subsample of Black mothers, with PRF again being the sole significant predictor of positive parenting. Further attention to cultural variations in PRF and parenting in future research is warranted.

INTRODUCTION/BACKGROUND: High-functioning depression (HFD) is described as experiencing depressive symptoms such as fatigue, anhedonia, poor concentration, guilt, restlessness, sleep disturbances, and appetite changes without experiencing a lack of functioning or significant distress. The purpose of this study is to characterize the clinical correlates of HFD. METHODS:This study entailed a descriptive, cross-sectional design based on interviews administered to120 English-speaking participants with HFD (aged 18-75). The interview involved administering a semi-structured HFD Analysis Questionnaire, the Joseph HFD Inventory, the HFD Trauma Inventory, and the Joseph HFD Anhedonia Scale in a single, 30-minute session for each participant. Big traumas, defined as extremely traumatic events, were analyzed by the trauma inventory. RESULTS:Out of the 120 participants, 72 (60%) demonstrated HFD, and 17 (14%) demonstrated very HFD. A correlation was observed between symptoms of HFD, such as anhedonia and marital status, as post hoc tests showed that the average Anhedonia Scale score was higher for married or partnered participants than those who were single (p=0.038). As anticipated, the participants with higher Anhedonia Scale scores had higher HFD scores (p=0.003). These participants also experienced higher trauma inventory scores and big traumas. Furthermore, as participant education level increased, the number of big traumas reported decreased (p<0.001). Participants who were parents/caregivers of children also had the highest Anhedonia Scale and HFD scores (p=0.0126 and p=0.0210, respectively). CONCLUSION/CONCLUSIONS:The results supported the hypothesis that individuals with HFD have increased levels of anhedonia and trauma. However, trauma scores were inversely associated with education level in HFD.

OBJECTIVE:This individual participant data meta-analysis aimed to investigate the effectiveness of cognitive behavioral therapy with a trauma focus (CBT-TF) for posttraumatic stress disorder (PTSD). Furthermore, we examined the effect of moderators on PTSD symptom severity. METHOD/METHODS:This study included randomized controlled trials comparing CBT-TF to an inactive or active comparison group for adults with PTSD. The primary and secondary outcomes were PTSD symptom severity and remission, respectively. Moderators included sociodemographic and clinical variables. RESULTS:Twelve studies compared CBT-TF with inactive (n = 625) and 11 with active comparison conditions (n = 706). The one-stage individual participant data meta-analysis found that CBT-TF was more effective than inactive comparison conditions (β = -0.78; OR = 2.34) and not significantly different from active comparison conditions (β = 0.02; OR = 0.53) in reducing PTSD symptom severity and achieving PTSD remission, respectively. When comparing CBT-TF with inactive treatments, moderator analysis found that divorced participants had greater PTSD symptoms postintervention following CBT-TF than participants who were single, cohabitating, or married receiving CBT-TF, both in the completer (β = 0.93) and full-sample (β = 0.59) analyses. For the active treatment comparison, moderator analysis found that participants taking psychotropic medication had lower PTSD symptoms following CBT-TF than those not taking psychotropic medication in the completer analysis (β = -0.39). CONCLUSION/CONCLUSIONS:Based on our moderator analyses, further research is needed to understand the effect of psychotropic medication on the CBT-TF intervention process. Moreover, divorced participants with PTSD receiving CBT-TF might benefit from enhanced support. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

BACKGROUND:Hyperexcitability in Alzheimer's disease (AD) is proposed to emerge early and contribute to disease progression. The dentate gyrus (DG) and its primary cell type, granule cells (GCs) are implicated in hyperexcitability in AD. Hence, we hypothesized that mossy cells (MCs), important regulators of GC excitability, contribute to early hyperexcitability in AD. Indeed, MCs and GCs are linked to hyperexcitability in epilepsy. METHODS:Using the Tg2576 model of AD and WT mice (~ 1 month-old), we compared MCs and GCs electrophysiologically and morphologically, assessed the activity marker c-Fos, Aβ expression and a hippocampal- and MC-dependent memory task that is impaired at 3-4 months of age in Tg2576 mice. RESULTS:Tg2576 MCs had increased spontaneous excitatory events (sEPSP/Cs) and decreased spontaneous inhibitory currents (sIPSCs), increasing the excitation/inhibition ratio. Additionally, Tg2576 MC intrinsic excitability was enhanced. Consistent with in vitro results, Tg2576 MCs showed enhanced c-Fos protein expression. Tg2576 MCs had increased intracellular Aβ expression, suggesting a reason for increased excitability. GCs showed increased excitatory and inhibitory input without changes in intrinsic properties, consistent with effects of increased MC activity. In support, increased GC activity was normalized by an antagonist of MC input to GCs. Also in support, Tg2576 MC axons showed sprouting to the area of GC dendrites. These effects occurred before an impairment in the memory task, suggesting they are extremely early alterations. CONCLUSIONS:Alterations in Tg2576 MCs and GCs early in life suggest an early role for MCs in increased GC excitability. MCs may be a novel target to intervene in AD pathophysiology at early stages.

INTRODUCTION/UNASSIGNED:Serotonergic psychedelics, serotonin 2A receptor agonists such as psilocybin that can result in substantially altered states of consciousness, are used in recreational and research settings. The safety of psychedelic experiences in research settings is supported by controlled physical environments, presence of clinical and medical staff to address emergent issues, screening for personal and family history of potential contraindications, and psychoeducational preparation with psychological support. Research settings typically provide psychoeducation to participants verbally and in writing (e.g., informed consent), and such documents and conversations can provide safety-related information-but may also introduce a wide range of expectancies. Such expectancies might involve the specific character of the acute subjective effects of psychedelics, possible side effects, and anticipated outcomes. METHODS/UNASSIGNED:To better understand the content of this psychoeducation, we gathered study materials from many psilocybin studies conducted in the past two decades in healthy and therapeutic populations. We conducted a reflexive thematic analysis to better understand these documents. RESULTS/UNASSIGNED:While these documents varied substantially between studies, we identified themes intended to lower levels of risk and optimize therapeutic effects from psychedelic treatments. The most frequently coded themes related to (1) biological and physical safety, (2) psychological safety and well-being, (3) aspects of setting, and (4) potential for expectancies. Prioritizing biological and psychological safety was evident in the materials from all sites. Furthermore, we identify potential contributors to expectancy unrelated to safety and suggest that these extrapharmacological elements be studied systematically in future research. CONCLUSIONS/UNASSIGNED:Ideally, future research should strive to maximize safety while attempting to minimize extraneous expectancies.
