Aims: This study aims to explore the concept of future orientation, which encompasses individuals' thoughts about the future, goal-setting, planning, response to challenges and behavioural adjustments in evolving situations. Often viewed as a psychological resource, future orientation is believed to be developed from psychological resilience. The study investigates the curvilinear relationship between childhood maltreatment and future orientation while examining the moderating effects of genotype.

Methods: A total of 14,675 Chinese adults self-reported their experiences of childhood maltreatment and their future orientation. The influence of genetic polymorphism was evaluated through genome-wide interaction studies (GWIS; genome-wide association study [GWAS] using gene × environment interaction) and a candidate genes approach.

Results: Both GWAS and candidate genes analyses consistently indicated that rs4498771 and its linked single-nucleotide polymorphisms, located in the intergenic area surrounding CSF3R, significantly interacted with early trauma to influence future orientation. Nonlinear regression analyses identified a quadratic or cubic association between future orientation and childhood maltreatment across some genotypes. Specifically, as levels of childhood maltreatment increased, future orientation declined for all genotypes. However, upon reaching a certain threshold, future orientation exhibited a rebound in individuals with specific genotypes.

Conclusions: The findings suggest that individuals with certain genotypes exhibit greater resilience to childhood maltreatment. Based on these results, we propose a new threshold model of stress-related growth.

Aims: Despite high levels of psychological distress, mental health service use among Syrian refugees in urban settings is low. To address the mental healthcare gap, the World Health Organization developed group problem management plus (gPM+), a scalable psychological intervention delivered by non-specialist peer facilitators. The study aimed to evaluate the effectiveness of gPM+ in reducing symptoms of depression and anxiety among Syrian refugees in Istanbul, Türkiye.

Methods: A randomized controlled trial was conducted among 368 distressed (Kessler Psychological Distress Scale, K10 > 15) adult Syrian refugees with impaired functioning (World Health Organization Disability Assessment Schedule, WHODAS 2.0 > 16). Participants were recruited between August 2019 and September 2020 through a non-governmental organization providing services to refugees. Participants were randomly allocated to gPM+ and enhanced care as usual (gPM+/E-CAU) (184 participants) or E-CAU only (184 participants). Primary outcomes were symptoms of depression and anxiety (Hopkins Symptom Checklist (HSCL-25)) at 3-month follow-up. Secondary outcomes were post-traumatic stress disorder (PTSD) symptoms (PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-5; PCL-5), functional impairment (WHODAS 2.0), and self-identified problems (psychological outcome profiles).

Results: Intent-to-treat analyses showed no significant effect of gPM+ on symptoms of anxiety, depression, PTSD and self-identified problems. Yet, there was a significant reduction in functional impairment in gPM+/E-CAU compared to E-CAU at 3-month follow-up (adjusted mean difference 1.66, 95 % CI 0.04, 3.27, p = 0.045, d = 0.19). Post-hoc subgroup analyses among participants with probable baseline depression or anxiety showed that there was a small but significant reduction in depression (adjusted mean difference -0.17, 95 % CI -0.32, -0.02, p = 0.028, d = 0.27) and anxiety (adjusted mean difference -0.21, 95 % CI -0.37, -0.05, p = 0.009, d = 0.30) symptoms comparing gPM+/E-CAU to E-CAU only at 1-week post assessment, but not at 3-month follow-up. There was a significant difference between conditions on functional impairment at 3-month follow-up, favouring gPM+/E-CAU condition (adjusted mean difference -1.98, 95 % CI -3.93, -0.02, p = 0.048, d = 0.26).

Conclusion: In this study in an urban setting in Türkiye, gPM+ did not alleviate symptoms of depression and anxiety among Syrian refugees experiencing psychological distress and daily living difficulties. However, participants with higher distress at baseline seemed to benefit from gPM+, but treatment gains disappeared in the long term. Current findings highlight the potential benefit of tailored psychosocial interventions for highly distressed refugees in volatile low-resource settings.

Aims: The concept of recovery is featured in the strategic plans of the World Health Organization as well as in other national mental health plans; however, there have been differing interpretations of what it means. This article aims to achieve a consensus on the key aspects of recovery in mental health from the perspective of movements of users and survivors of psychiatry at an international level. Four specific objectives were proposed in this study: (1) to identify what recovery in mental health means, (2) to identify the indicators that a person is progressing in their recovery, (3) to determine the factors that facilitate the recovery process, and (4) to determine the factors that hinder the recovery process.

Methods: A three-round e-Delphi study was conducted with the participation of 101 users and survivors of psychiatry, adhering to the CREDES checklist to ensure methodological rigour.

Results: The results reveal 26 key aspects that define recovery, 31 indicating that a person is progressing in their recovery process, 8 that facilitate recovery and 12 that hinder recovery. The most agreed-upon statements for defining recovery highlight the importance of empowerment, leading a fulfilling life, ensuring safe-living conditions and acknowledging individuals as holders of rights. Similarly, empowerment and agency were highly agreed upon as relevant recovery indicators. Key findings underscore the significance of a supportive and respectful social environment in facilitating recovery, while coercion, discrimination and lack of support from significant others hinder recovery.

Conclusions: Despite cultural differences and recovery's subjective nature, our results demonstrate that an international consensus on critical recovery aspects is attainable. Highlighting a significant shift, we emphasize the 'Transition' process to signify moving away from the biomedical model approach and advocating for collective rights. Our findings advocate for empowerment, users' rights and the move towards person-centred care that integrates social, political and economic contexts. These consensus statements lay the groundwork for future research across diverse regions and cultures, offering insights into recovery's meaning and potential for innovative approaches in diagnosis, intervention and evaluation.

Aims: Research evidence has established an association of obsessive-compulsive disorder (OCD) with suicidal thoughts and suicide attempts. However, further investigation is required to determine whether individuals with OCD have higher risk of death by suicide compared with those without OCD.

Methods: Of the entire Taiwanese population, between 2003 and 2017, 56,977 individuals with OCD were identified; they were then matched at a 1:4 ratio with 227,908 non-OCD individuals on the basis of their birth year and sex. Suicide mortality was assessed between 2003 and 2017 for both groups. Time-dependent Cox regression models were used to investigate the difference in suicide risk between individuals with versus without OCD.

Results: After adjustment for major psychiatric comorbidities (i.e., schizophrenia, bipolar disorder and major depressive disorder), the OCD group had higher risk of suicide (hazard ratio: 1.97, 95% confidence interval: 1.57-2.48) during the follow-up compared with the comparison group. Furthermore, OCD severity, as indicated by psychiatric hospitalizations due to OCD, was positively correlated with suicide risk.

Conclusions: Regardless of the existence of major psychiatric comorbidities, OCD was found to be an independent risk factor for death by suicide. A suicide prevention program specific to individuals with OCD may be developed in clinical practice in the future.
