AI Article Synopsis
- This study looked at how past traumatic events affect PTSD and depression in Asian patients with mood disorders.
- It found that feeling supported by others can help reduce PTSD symptoms that come from these traumatic events.
- The results can help improve treatments for PTSD but may not apply to people outside of Singapore because of different cultures.
Article Abstract
Background: Social support is a robust predictor of post-traumatic stress disorder (PTSD). Although the inverse relationship between perceived social support and PTSD (social causation model) is supported, less is understood about the antecedents of the social causation model. Further, there is limited research in non-Western psychiatric populations that experience elevated rates of trauma and PTSD (e.g., mood disorders). The present study evaluated whether cumulative traumatic life events influenced current PTSD symptoms through maladaptive personality traits and perceptions of social support among Asian patients with mood disorders.
Methods: A total of 200 Asian patients (77.5 % Chinese) with mood disorders were assessed for maladaptive personality traits, perceptions of social support, cumulative traumatic life events, PTSD, and depressive symptoms. Structural equation modelling was conducted to evaluate the extended social causation model.
Results: The extended social causation model demonstrated acceptable fit to the data (Comparative Fit Index [CFI] = 0.90; absolute Root Mean Square Error of Approximation [RMSEA] = 0.08). There were significant indirect effects of cumulative traumatic life events on current PTSD symptoms (β = 0.29, p < .001; 85 % variance explained) and depressive symptoms (β = 0.28, p < .001; 69 % variance explained).
Limitations: Results may not be generalizable beyond the Singapore population due to the socio-cultural and environmental context.
Conclusions: The present findings provide conceptual support for a maladaptive personality-informed model of social support and PTSD, which could better inform trauma-focused interventions in preventing and treating the debilitating effects of PTSD in psychiatric populations.

Background/purpose: Immunotherapies, such as CAR-T, have revolutionized cancer treatment for some cancers. However, these treatments often require active participation of a family member or friend to act as a caregiver at home for several weeks after infusion. Given the novelty of CAR-T, there is a need to better understand the experience of patients receiving these treatments and their caregivers.

This study aimed to assess measurement invariance for the Five-Factor Inventory for (Oltmanns & Widiger, 2020) across nine national samples from four continents ( = 6,342), and to validate a French translation in seven French-speaking national samples. All were convenience samples of adults. Exploratory factor analyses supported a four-factor structure in the French-speaking Western samples (Belgium, Canada, France, and Switzerland) while a three-factor structure was preferred in the French-speaking African samples (Burkina Faso and Togo), and no adequate structure was found in the Indian sample.

Support for people living with HIV (PLHIV) as they disclose their HIV status can impact continuity of HIV treatment and adherence to antiretrovirals. In the presence of multi-level adversities, resilience among PLHIV can promote health-seeking behaviors and better health outcomes. However, few studies have examined how disclosure experience and resilience work together to impact HIV treatment outcomes among PLHIV.

A growing body of literature has confirmed the within-person process from interpersonal conflict to adolescent mood on a day-to-day timescale. However, research on how, when and for whom adolescent interpersonal conflict relates to their daily mood is underdeveloped. This study examined whether interpersonal conflict is related to mood through threat appraisal and self-blaming attribution and whether these relationships would be moderated by daily social support and psychological capital.
