Evaluating a maladaptive personality-informed model of social support and post-traumatic stress disorder.

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 (ß = 0.29, p < .001; 85 % variance explained) and depressive symptoms (ß = 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.

Selection of New Psychiatry Residents Within a National Program: a Qualitative Study of Faculty Perspectives on Competencies and Attributes.

OBJECTIVE: Admission committees use multiple sources of information to select residents. However, the way in which faculty members use each data source remains unclear and highly context-specific. The present study seeks to understand how faculty members use various sources of information about candidates to make admission decisions to a National Psychiatry Residency Program. METHODS: The theory of core competencies was used as a foundation for this qualitative study. Framework analysis was used to structure the project and data presentation. Twenty key informants from the faculty were purposefully sampled in accordance with the initial theory. Open-ended semi-structured interviews were conducted to obtain their views about the essential competencies of psychiatrists and the ways in which these competencies could be reliably gauged. RESULTS: Participants described numerous competencies that they believed were essential to becoming competent psychiatrists. These competencies fell within the six core competencies of the Accreditation Council for Graduate Medical Education framework. However, several non-competency attributes (such as perseverance, empathy, and compassion) were also relevant in the selection process. To reduce the impact of self-presentation bias, to which these attributes were vulnerable, the faculty relied heavily on sources of information obtained from third parties, such as feedback from co-workers with first-hand experience of the candidate during their clinical placements. CONCLUSION: Faculty members place importance on informal informant-derived information about a candidate's non-competency attributes in addition to core competencies when deciding whether or not to select a candidate for admission into a residency training program.
