Posttraumatic stress disorder symptom clusters and acquired capability for suicide: A reexamination using DSM-5 criteria
Elizabeth G Spitzer, Kelly L Zuromski, Margaret T Davis, Tracy K Witte, Frank Weathers.
This study used the interpersonal–psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS. JEUNE-ADULTE ÉTUDIANT-UNIVERSITAIRE TROUBLE-STRESS-POST-TRAUMATIQUE
