Abstract

Guilt is associated with posttraumatic stress disorder (PTSD), depression, and suicidality, all of which are prevalent problems among active-duty and veteran United States military personnel. Most research studying these associations utilize trauma-related guilt conceptualizations. However, researchers have developed and begun testing the Interpersonal Guilt Rating Scale-15 Item Self-Report Version (IGRS-15s), which has shown strong psychometric properties in samples of Italian and English-speaking civilians. The present study evaluated the IGRS-15s in a sample of 229 American Post 9/11 combat veterans to understand its utility in this community. We hypothesized and found a four-factor structure in congruence with prior studies of English-speaking samples. As hypothesized, the IGRS-15s was strongly correlated to other measures of guilt and PTSD and was moderately correlated to a measure of depression. Overall, the measure showed good internal consistency and displayed convergent associations with other measures of guilt. As such, the IGRS-15s may be a useful, brief, self-report tool for assessing guilt in military-affiliated communities.
