Applying and Extending the Conservation of Resources (COR) Model to Trauma in U.S. Veterans

Abstract

This was a novel pilot study about the relationship between PTSD severity and resource gain and loss using the conservation of resources (COR) model with U.S. Veterans. Higher PTSD severity was predicted to be associated with greater resource loss scores, and lower PTSD scores were predicted to be associated with greater resource gain scores. The sample size was limited (N = 19) due to the COVID-19 outbreak. Veterans completed a demographic questionnaire, the Montreal Cognitive Assessment (MoCA), the Combat Exposure Scale (CES), the PTSD Symptom Scale–Interview (PSS-I), the Conservation of Resources–Evaluation (COR-E), and two additional open-ended questions. A statistically significant negative medium effect size was found between PTSD diagnosis and resource gain (r(17) = −0.42, p = 0.039, one-tailed). A large effect size in resource gain scores between PTSD and non-PTSD groups was also found (t(17) = 1.880, p = 0.077, d = 0.87), with the non-PTSD group reporting more gain of resources than the PTSD group. Post hoc tests revealed that the resource gain score of the mild PTSD group was significantly higher than that of the severe + very severe PTSD group (p = 0.034). Results suggest that resource gain, when compared to resource loss, was the strongest predictor for a non-PTSD diagnosis.
