Examining the Moderating Effects of Anger between the Latent factors of Posttraumatic Stress Disorder and Depression

Abstract Details

2015, Master of Arts, University of Toledo, Psychology - Clinical.
The purpose of the present study was twofold. First, further investigation of the DSM-5 posttraumatic stress disorder (PTSD) model is needed given the recent publication of DSM-5 and minimal amount of empirical investigation as of yet (Elhai, Miller, et al., 2012; Friedman, Resick, Bryant, & Brewin, 2011; Koffel, Polusny, Arbisi, & Erbes, 2012; Miller et al., 2012). Second, I investigated the moderating effect of anger between specific latent factors of PTSD and somatic and non-somatic depression. Comorbidity rates between PTSD and major depression run as high as 48-55% (Elhai, Grubaugh, Kashdan, & Frueh, 2008; Kessler, Sonnega, Bromet, & Hughes, 1995); these striking rates give rise to the importance of the present study. No studies to date have investigated anger as a possible moderator despite the high prevalence of anger in individuals with PTSD and depression independently. The present study was conducted using University of Toledo undergraduate students. Following a prescreen questionnaire, subjects completed the following measures online within a secure web platform: demographics questionnaire, the Stressful Life Events Screening Questionnaire (SLESQ), the Posttraumatic Stress Disorder Checklist (PCL), the Patient Health Questionnaire (PHQ) and the Dimensions of Anger Reactions (Bremner, Southwick, Darnell, & Charney). For the analyses, two confirmatory factor analyses (CFA) were conducted to investigate model fit for the DSM-5 PTSD model and the PTSD dysphoria model. In addition, three moderation analyses were conducted to investigate (1) if anger moderates the relationship between PTSD’s dysphoria factor and somatic depression, (2) if anger moderates the relationship between PTSD’s dysphoria factor and non-somatic depression and (3) if anger moderates the relationship between PTSD’s hyperarousal factor and somatic depression. Results and implications are discussed.
