Posttraumatic stress symptoms, posttraumatic growth, and personality factors: A network analysis.

BACKGROUND: After experiencing a traumatic event, two possible outcomes are experiencing positive changes, such as posttraumatic growth (PTG), and/or experiencing distress in the form of posttraumatic stress symptoms (PTSS). These constructs are not mutually exclusive; those who experience PTSS may concurrently or at a later date likewise undergo PTG. Pretrauma factors, such as personality as measured by the Big Five Inventory (BFI), can interact with both PTSS and PTG. METHODS: The present study utilized Network theory to examine the interactions between PTSS, PTG, and personality in 1310 participants. Three networks were computed (PTSS, PTSS/BFI, PTSS/PTG/BFI). RESULTS: Within the PTSS network, strong negative emotions emerged as the strongest influence on the network. Again, in the PTSS and BFI network, strong negative emotions exerted the strongest overall influence in addition to bridging the PTSS and personality domains. In the network with all variables of interest, the PTG domain of new possibilities was the strongest overall influence on the network. Specific relationships between constructs were identified. LIMITATIONS: Limitations of this study include the cross-sectional design and utilization of a sub-threshold PTSD, non-treatment seeking sample. CONCLUSIONS: Overall, nuanced relationships between variables of interest were identified, informing personalized treatment and furthers our understanding of both positive and negative responses to trauma. As the primary influence across two networks, the experience of strong negative emotions appears to be central to the subjective experience of PTSD. This may indicate a need to modify present treatments for PTSD, which conceptualize PTSD as a primarily fear-based disorder.

Predictors of Attrition and Response in Cognitive Processing Therapy for Interpersonal Trauma Survivors with PTSD.

With the establishment of empirically validated treatments for posttraumatic stress disorder (PTSD), concerns remain regarding the effectiveness of such treatments in real-world clinical settings. Specifically, premature termination and treatment response limit the effectiveness of these interventions. The current study investigated factors potentially related to premature termination and treatment response in Cognitive Processing Therapy with Account (CPT-A). Participants in this study included 42 women (Mage = 30.70 SDage = 9.40) with PTSD from exposure to interpersonal trauma. Demographic characteristics, pre-treatment symptoms of PTSD and depression, and transdiagnostic factors were examined as predictors of attrition and treatment response. Hierarchical regression and logistic regression models were analyzed to test the variance explained and predictive value of these factors. The present study revealed that age was a significant factor related to dropout from CPT-A whereas baseline PTSD symptom severity was significantly related to treatment response. Results of this study suggest the importance of the interrelationships among pre-treatment predictors as well as the consideration of attrition and treatment response as distinct metrics of treatment outcome. Further, these results inform the application of CPT-A for PTSD in survivors of interpersonal trauma, as consideration of the identified predictors of dropout and non-response at intake may contribute to treatment retention and response.

The differential relation of trauma types with negative and positive emotion dysregulation.

Background and Objectives: Research provides robust support for an association between traumatic exposure and emotion dysregulation. Less understood is the relation of emotion dysregulation stemming from positive emotions to traumatic exposure, or the extent to which negative and positive emotion dysregulation may be uniquely related to specific trauma types.Design and Methods: The present study explored the associations between negative and positive emotion dysregulation and specific trauma types in a community sample of 433 adults (M age = 43.81, 68.4% women).Results: Results highlighted three main findings: (1) negative and positive emotion dysregulation were significantly higher among individuals with vs. without exposure to six and nine specific trauma types, respectively; (2) negative and positive emotion dysregulation were significantly and positively related to total number of specific traumatic events; and (3) negative emotion dysregulation was significantly higher among individuals with Victimization Traumas in the overall sample as well as the no-PTSD and no-MDD subsamples, and positive emotion dysregulation was significantly lower among individuals with Accidental/Injury Traumas and Victimization Traumas in the PTSD subsample.Conclusions: Results underscore the relative and unique roles of negative and positive emotion dysregulation in trauma types; these findings may inform future research.
