Family composition and symptom severity among Veterans with comorbid PTSD and substance use disorders

摘要

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) frequently co-occur and affect a substantial proportion of military Veterans. Although the impact of parental PTSD and SOD on child development is well-documented, little is known about the influence of family composition on PTSD/SUD symptom severity. The present study investigated children in the home as an independent risk factor for symptom severity in a sample of treatment-seeking Veterans (N = 94; 92% male) with comorbid PTSD/SUD. Twenty-seven percent of the sample had minor children (age 18 or younger) living in the home. Veterans with children in the home evidenced significantly higher PTSD symptomatology as measured by the Clinical Administered PTSD Scale (CAPS; M = 82.65 vs. M = 72.17; t = 2.18; p < .05), and reported using marijuana more frequently than Veterans without children in the home (34% vs. 13% of past 60 days; t = 2.35,p < .05). In a multivariate model, having children in the home accounted for unique variance (Delta R-2 = .07) in PTSD severity after accounting for a range of covariates; however, having children in the home did not account for unique variance in substance use. Directions for future research as well as potential clinical implications for parents seeking treatment for PTSD/SUD are discussed. (C) 2015 Elsevier Ltd. All rights reserved.
