Development and Evaluation of the Perpetration‐Induced Distress Scale for Measuring Shame and Guilt in Civilian Populations

摘要

Abstract Although the topic of moral injury (MI) has been garnering increasing attention in recent years within military populations, research has rarely applied the concept to civilian contexts. Extant literature on distinct acts of perpetration or transgressions suggests similar emotional, cognitive, and behavioral patterns of distress associated with appraisals of wrongdoing. However, the absence of a psychometrically sound measure to detect and quantify pathological levels of distress associated with perpetrating harm against others has hindered additional research from being conducted on the topic. The current research presents the Perpetration‐Induced Distress Scale (PIDS) as a valid and reliable measurement of distress associated with MI within civilian contexts. Factor analytic techniques revealed a two‐factor solution characterized by perpetration‐induced distress related to maladaptive reactions to shame (seven items) and guilt/self‐blame (seven items). The PIDS demonstrated favorable temporal stability over a 1‐week period as well as excellent internal reliability. Further, the PIDS evidenced convergent validity with functional impairment, posttraumatic stress disorder, and existing scales of shame and gui associations were large (rs = 0.62–0.87). The development of the PIDS represents one of the first studies to measure MI within a civilian population and indicates evidence that additional research on the topic is warranted.
