The mediating role of emotion dysregulation in the association between trait mindfulness and PTSD symptoms among trauma-exposed adults.

ABSTRACT:

Objectives

Growing evidence of the effectiveness of mindfulness-based interventions for posttraumatic stress disorder (PTSD) warrants greater understanding of factors relevant to the relation between trait mindfulness and PTSD, such as emotion dysregulation (ED). The goal of this study was to examine associations between trait mindfulness, ED, and PTSD symptoms across two samples of trauma-exposed adults.

Methods

Participants for Sample 1 (n = 39, 90% women, 100% Black) and Sample 2 (n = 60, 100% women, 87% Black) were recruited from an urban hospital in the South. Trait mindfulness, ED, and PTSD were assessed.

Results

Across both samples, mindfulness and ED were significantly associated with overall PTSD severity (r = -.49 and r = -.42, ps = .001; r = .53 and r = .51, ps < .001, respectively) in the expected direction. In Sample 1, mindful nonjudgment and difficulty with emotion regulation strategies showed the strongest associations with overall PTSD severity as well as symptom clusters. In Sample 2, mindful acceptance and all ED dimensions (except non-awareness) showed strong associations with overall PTSD severity and particularly with negative cognitions and mood symptoms. In both samples, ED mediated the association between mindfulness and overall PTSD severity (Sample 1: ab = -.15, 95%CI [-.35, -.02]; Sample 2: ab = -.11, 95%CI [-.22, -.04]).

Conclusions

These findings demonstrate the important role of ED in the relation between trait mindfulness and PTSD symptoms among trauma-exposed adults. They highlight the value of examining ED as a mechanism of change in mindfulness-based interventions for PTSD.

Project description:BackgroundPost-traumatic stress disorder (PTSD) is an established comorbidity in Bipolar Disorder (BD), but little is known about the characteristics of psychological trauma beyond a PTSD diagnosis and differences in trauma symptoms between BD-I and BD-II.Objective(1) To present characteristics of a trauma-exposed BD sample; (2) to investigate prevalence and trauma symptom profile across BD-I and BD-II; (3) to assess the impact of a lifetime PTSD diagnosis vs. a history of trauma on BD course; and (4) to research the impacts of sexual and physical abuse.MethodsThis multi-center study comprised 79 adult participants with BD with a history of psychological trauma and reports baseline data from a trial registered in Clinical Trials (https://clinicaltrials.gov; ref: NCT02634372). Clinical variables were gathered through clinical interview, validated scales and a review of case notes.ResultsThe majority (80.8%) of our sample had experienced a relevant stressful life event prior to onset of BD, over half of our sample 51.9% had a lifetime diagnosis of PTSD according to the Clinician Administered PTSD scale. The mean Impact of Event Scale-Revised scores indicated high levels of trauma-related distress across the sample, including clinical symptoms in the PTSD group and subsyndromal symptoms in the non-PTSD group. Levels of dissociation were not higher than normative values for BD. A PTSD diagnosis (vs. a history of trauma) was associated with psychotic symptoms [2(1) = 5.404, p = 0.02] but not with other indicators of BD clinical severity. There was no significant difference between BD-I and BD-II in terms of lifetime PTSD diagnosis or trauma symptom profile. Sexual abuse significantly predicted rapid cycling [2(1) = 4.15, p = 0.042], while physical abuse was not significantly associated with any clinical indicator of severity.ConclusionTrauma load in BD is marked with a lack of difference in trauma profile between BD-I and BD-II. Although PTSD and sexual abuse may have a negative impact on BD course, in many indicators of BD severity there is no significant difference between PTSD and subsyndromal trauma symptoms. Our results support further research to clarify the role of subsyndromic PTSD symptoms, and highlight the importance of screening for trauma in BD patients.
