RESUMO
BACKGROUND: Young people are most vulnerable to suicidal behaviours but least likely to seek help. A more elaborate study of the intrinsic and extrinsic correlates of suicidal ideation and behaviours particularly amid ongoing population-level stressors and the identification of less stigmatising markers in representative youth populations is essential. METHODS: Participants (n = 2540, aged 15-25) were consecutively recruited from an ongoing large-scale household-based epidemiological youth mental health study in Hong Kong between September 2019 and 2021. Lifetime and 12-month prevalence of suicidal ideation, plan, and attempt were assessed, alongside suicide-related rumination, hopelessness and neuroticism, personal and population-level stressors, family functioning, cognitive ability, lifetime non-suicidal self-harm, 12-month major depressive disorder (MDD), and alcohol use. RESULTS: The 12-month prevalence of suicidal ideation, ideation-only (no plan or attempt), plan, and attempt was 20.0, 15.4, 4.6, and 1.3%, respectively. Importantly, multivariable logistic regression findings revealed that suicide-related rumination was the only factor associated with all four suicidal outcomes (all p < 0.01). Among those with suicidal ideation (two-stage approach), intrinsic factors, including suicide-related rumination, poorer cognitive ability, and 12-month MDE, were specifically associated with suicide plan, while extrinsic factors, including coronavirus disease 2019 (COVID-19) stressors, poorer family functioning, and personal life stressors, as well as non-suicidal self-harm, were specifically associated with suicide attempt. CONCLUSIONS: Suicide-related rumination, population-level COVID-19 stressors, and poorer family functioning may be important less-stigmatising markers for youth suicidal risks. The respective roles played by not only intrinsic but also extrinsic factors in suicide plan and attempt using a two-stage approach should be considered in future preventative intervention work.

Restrictive COVID-19 measures can have significant mental health impacts, particularly on young people. How such measures may influence day-to-day momentary affect, nonetheless, remains to be explored. Experience sampling data were collected from 165 young people (aged 15-24) as part of a larger epidemiological youth mental health study in Hong Kong. We examined the impact of one of the most stringent COVID-19 measures - dine-in restrictions - on momentary positive and negative affect and current contexts and activities of these young people. The effects of a milder form of COVID-19 measure - school suspension - were separately examined. Multilevel analysis revealed that those in the dine-in ban group, compared to dining-as-usual, showed significantly reduced momentary positive affect (ß = -0.17, SE = 0.06, p = 0.003). Its effect remained significant even when accounting for baseline depressive and anxiety symptoms and socioeconomic status (ß = -0.15, SE = 0.05, p = 0.008). The effect of dine-in ban on reduced momentary positive affect was found specifically when participants were in indoor locations (e.g., home, office), alone, and engaged in passive leisure activities. This pattern was not observed when participants were at school or at other outdoor locations, with friends, or engaged in active leisure activities. No significant effect of school suspension on momentary affect was observed. More severe COVID-19 measures, such as dine-in ban, can have significant impacts on the momentary positive affect of young people. Certain contexts and activities may offer protection against the consequences of COVID-19 measures. The current findings may help to inform future designs of mental health interventions and public health policies.

RESUMO
OBJECTIVES: The co-occurrence of different classes of population-level stressors, such as social unrest and public health crises, is common in contemporary societies. Yet, few studies explored their combined mental health impact. The aim of this study was to examine the impact of repeated exposure to social unrest-related traumatic events (TEs), coronavirus disease 2019 (COVID-19) pandemic-related events (PEs), and stressful life events (SLEs) on post-traumatic stress disorder (PTSD) and depressive symptoms, and the potential mediating role of event-based rumination (rumination of TEs-related anger, injustice, guilt, and insecurity) between TEs and PTSD symptoms. METHODS: Community members in Hong Kong who had utilized a screening tool for PTSD and depressive symptoms were invited to complete a survey on exposure to stressful events and event-based rumination. RESULTS: A total of 10,110 individuals completed the survey. Hierarchical regression analysis showed that rumination, TEs, and SLEs were among the significant predictors for PTSD symptoms (all P < 0.001), accounting for 32% of the variance. For depression, rumination, SLEs, and PEs were among the significant predictors (all P < 0.001), explaining 24.9% of the variance. Two-way analysis of variance of different recent and prior TEs showed significant dose-effect relationships. The effect of recent TEs on PTSD symptoms was potentiated by prior TEs (P = 0.005). COVID-19 PEs and prior TEs additively contributed to PTSD symptoms, with no significant interaction (P = 0.94). Meanwhile, recent TEs were also potentiated by SLEs (P = 0.002). The effects of TEs on PTSD symptoms were mediated by rumination (ß = 0.38, standard error = 0.01, 95% confidence interval: 0.36 to 0.41), with 40.4% of the total effect explained. All 4 rumination subtypes were significant mediators. CONCLUSIONS: Prior and ongoing TEs, PEs, and SLEs cumulatively exacerbated PTSD and depressive symptoms. The role of event-based rumination and their interventions should be prioritized for future research.

This study examined the epidemiology of trauma exposure (TE) and posttraumatic stress disorder (PTSD) among community-dwelling Chinese adults in Hong Kong. Multistage stratification sampling design was used, and 5,377 participants were included. In Phase 1, TE, probable PTSD (p-PTSD), and psychiatric comorbid conditions were examined. In Phase 2, the Structured Clinical Interview for the DSM-IV (SCID-I) was used to determine the weighted diagnostic prevalence of lifetime full PTSD. Disability level and health service utilization were studied. The findings showed that the weighted prevalence of TE was 64.8%, and increased to 88.7% when indirect TE types were included, with transportation accidents (50.8%) reported as the most common TE. The prevalence of current p-PTSD among participants with TE was 2.9%. Results of logistic regression suggested that nine specific trauma types were significantly associated with p-PTSD; among this group, severe human suffering, sexual assault, unwanted or uncomfortable sexual experience, captivity, and sudden and violent death carried the greatest risks for developing PTSD, odds ratio (OR) = 2.32-2.69. The occurrence of p-PTSD was associated with more mental health burdens, including (a) sixfold higher rates for any past-week common mental disorder, OR = 28.4, (b) more mental health service utilization, p < .001, (c) poorer mental health indexes in level of symptomatology, suicide ideation and functioning, p < .001, and (d) more disability, ps < .001-p = .014. The associations found among TE, PTSD, and health service utilization suggest that both TE and PTSD should be considered public health concerns.
Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) La Encuesta Hong Kong sobre la Epidemiología de las Experiencias Traumáticas y el Trastorno de Estrés Postraumático ENCUESTA HONG KONG SOBRE EXPERIENCIA TRAUMÁTICA Y TEPT Este estudio examinó la epidemiología de la experiencia traumática (ET) y el trastorno por estrés postraumático (TEPT) entre adultos chinos que viven en comunidades en Hong Kong. Se utilizó un diseño de muestreo de estratificación multietapa y se incluyeron 5,377 participantes. En la Fase 1, ET, probable TEPT (p-TEPT) y enfermedades psiquiátricas comórbidas fueron examinadas. En la Fase 2, se utilizó la Entrevista Clínica Estructurada para el DSM-IV (SCID-I) para determinar la prevalencia de diagnóstico ponderado de TEPT completo a lo largo de la vida. Se estudiaron el nivel de discapacidad y la utilización de los servicios de salud. Los resultados mostraron que la prevalencia ponderada de ET fue del 64.8% y aumentó al 88.7% cuando se incluyeron tipos indirectos de ET, tales como accidentes de transporte (50.8%), los que fueron reportados como el ET más común. La prevalencia actual de p-TEPT entre los participantes con ET fue del 2.9%. Los resultados de la regresión logística sugirieron que nueve tipos específicos de trauma fueron significativamente asociados con p-PTSD; entre este grupo encontramos: sufrimiento humano severo, agresión sexual, experiencia sexual no deseada o incómoda, cautiverio y la muerte inesperada y violenta acarrearon el mayor riesgo para desarrollar TEPT, odds ratio (OR) = 2.32-2.69. La aparición de p-PTSD fue asociado con más riesgo de problemas de salud mental, que incluyen (a) tasas 6 veces más altas para cualquier trastorno mental común experimentado la última semana, OR = 28.4 (b) más utilización de servicios de salud mental, p <.001, (c) índices de salud mental más pobres a nivel de sintomatología, ideación y funcionamiento suicida, p <.001, y (d) más discapacidad, p <.001 - p = .014. Las asociaciones encontradas entre ET, TEPT, y la utilización de los servicios de salud sugieren que tanto el ET como el TEPT deben considerarse una preocupación de salud pública.

Elevated aggression in individuals with psychiatric disorders is frequently reported yet aggressive acts among people with mental illness are often intertwined with proneness to aggression and other risk factors. Evidence has suggested that both general psychopathology and proneness to aggression may share common psychological characteristics. This study aims to investigate the complex relationship between general psychopathology, proneness to aggression, and their contributing factors in community youth. Here, we first examined the association between proneness to aggression and the level of general psychopathology in 2184 community youths (male: 41.2%). To identify common characteristics, we trained machine learning models using LASSO based on 230 features covering sociodemographic, cognitive functions, lifestyle, well-being, and psychological characteristics to predict levels of general psychopathology and proneness to aggression. A subsequent Gaussian Graph Model (GGM) was fitted to understand the relationships between the general psychopathology, proneness to aggression, and selected features. We showed that proneness to aggression was associated with a higher level of general psychopathology (discovery: r = 0.56, 95% CI: [0.52-0.59]; holdout: r = 0.60, 95% CI: [0.54-0.65]). The LASSO model trained on the discovery dataset for general psychopathology was able to predict proneness to aggression in the holdout dataset with a moderate correlation coefficient of 0.606. Similarly, the model trained on the proneness to aggression in the discovery dataset was able to predict general psychopathology in the holdout dataset with a correlation coefficient of 0.717. These results suggest that there is substantial shared information between the two outcomes. The GGM model revealed that isolation and impulsivity factors were directly associated with both general psychopathology and proneness to aggression. These results revealed shared psychological characteristics of general psychopathology and proneness to aggression in a community sample of youths.

Background: Hong Kong is among the many populations that has experienced the combined impacts of social unrest and the COVID-19 pandemic. Despite concerns about further deteriorations in youth mental health globally, few epidemiological studies have been conducted to examine the prevalence and correlates of major depressive episode (MDE) and other major psychiatric disorders across periods of population-level changes using diagnostic interviews. Methods: We conducted a territory-wide household-based epidemiological study from 2019 to 2022 targeting young people aged 15-24 years. MDE, generalised anxiety disorder (GAD), panic disorder (PD), and bipolar disorder (BD) were assessed using the Composite International Diagnostic Interview-Screening Scales in 3340 young people. Psychotic disorders were assessed by experienced psychiatrists according to the DSM. Help-seeking patterns were also explored. Findings: 16.6% had any mental disorder (13.7% 12-month MDE, 2.3% BD, 2.1% GAD, 1.0% PD, 0.6% psychotic disorder). The prevalence of MDE increased from 13.2% during period 1 (May 2019-June 2020) to 18.1% during period 2 (July-December 2020), followed by 14.0% during period 3 (January-June 2021) and 13.2% during period 4 (July 2021-June 2022). Different stressors uniquely contributed to MDE across periods: social unrest-related stressors during period 1, COVID-19 stressors during period 2, and personal stressors during periods 3-4. Lower resilience, loneliness, frequent nightmares, and childhood adversity were consistently associated with MDE. Compared to other conditions, those with MDE showed the lowest service utilisation rate (16.7%). Perceiving services to "cost too much" and "talked to friends or relatives instead" were among the major reasons for not seeking help. MDE was also significantly associated with poorer functioning and health-related quality of life. Interpretation: MDE can be sensitive to population-level changes, although its persistently elevated prevalence across the study period is of concern. Efforts to mitigate their impacts on youth mental health alongside personal risk factors are needed. Further work is required to increase the availability and acceptability of youth-targeted mental health services. Funding: Food and Health Bureau (HKSAR Government).
RESUMO
AIM: Hong Kong's existing mental health services are inadequate in addressing young people's needs. The LevelMind@JC project established an early intervention platform of community-based youth-specific mental health centres involving youth workers, cross-disciplinary professionals, and young people. The project intends to (1) pilot a community platform that incorporates a youth-friendly early screening tool with preventative intervention capabilities, (2) set up a state-of-the-art training system for youth mental health workers, (3) establish a community clinical support team and (4) develop a timely evaluation system to monitor the service and evaluate its outcome and cost-effectiveness against generic youth services. METHODS: Six hundred LevelMind@JC service users will be assessed alongside 600 young people visiting generic youth centres and 100 young people in the community. Participants will be matched according to age, gender, years of education, socioeconomic status, and level of distress. Assessments, administered at baseline and at 3, 6 and 12 months, will cover demographic characteristics, psychological distress, quality of life, depressive and anxiety symptoms, functioning, physical health and lifestyle, personality and social measures, cognitive measures and health economics. Mixed-model ANOVAs will be used to indicate interactions between services and between time points. CONCLUSION: Built upon a community-based support model, LevelMind@JC aims to promote positive mental health in young people through the collaboration of cross-disciplinary mental health professionals. If efficacy and cost-effectiveness are established, the project could be scaled up, implicating a wider reach of care. We anticipate its success to be critical in combatting mental health issues stemming from both personal and population-level stressors.

Ideas of reference (IOR) are often implicated in predicting psychosis onset. They have been conceptualized to present on a continuum, from oversensitive psychological reactions to delusional thoughts. It is however unknown to what extent IOR may be triggered by collective environmental stress. We obtained timely data from 9873 individuals to assess IOR in relation to trauma exposure in the 2019-2020 social unrest in Hong Kong. Two levels of IOR are distinguished: attenuated IOR (IOR-A), being the experience of feeling particularly referred to within a group; and exclusive IOR (IOR-E), the experience of feeling exclusively referred to while others are not. Logistic regressions showed that event-based rumination was a shared predictor for IOR-A (OR = 1.07, CI = 1.03-1.10) and IOR-E (OR = 1.09, CI = 1.02-1.17). For IOR-A, three categories of social unrest-related traumatic events (TEs) were significant predictors, including being attacked or having experienced sexual violence (OR = 4.14, CI = 1.93-8.85), being arrested (OR = 4.48, CI = 1.99-10.10), and being verbally abused (OR = 2.66, CI = 1.28-5.53). Being arrested was significant for IOR-E (OR = 3.87, CI = 1.03-14.52), though not when rumination was included. Education level also significantly predicted IOR-E (OR = 0.72, CI = 0.52-0.99). Further analysis revealed that rumination significantly mediated between TEs and IOR severity (ß = 0.26, SE = 0.01, CI = 0.24-0.28). The findings are consistent with the hypothesis that IOR-A and IOR-E occur as levels on a continuum, but each has some distinctive correlates. Extrinsic events may play a more prominent role in IOR-A, while intrinsic factors, such as cognitive capacity, may play a more prominent role in IOR-E. The involvement of rumination across the IOR spectrum suggests an opportunity for intervention.
