Development and validation of the Trauma-Related Guilt Inventory (TRGI).

The article describes the development and psychometric evaluation of the Trauma-Related Guilt Inventory (TRGI). An initial questionnaire was constructed from multiple sources of information. Three factor analytic studies were conducted to refine the TRGI and determine its factor structure, which consists of a Distress factor and three cognitive factors, Hindsight-Bias/Responsibility, Wrongdoing, and Lack of Justification. The TRGI has high internal consistency and adequate temporal stability. In validity studies with Vietnam veterans and battered women, TRGI scales and subscales were significantly correlated with other measures of guilt and with measures of posttraumatic stress disorder, depression, and other indexes ofadjustment. Findings support the conceptualization of trauma-related guilt as a multidimensional construct and highlight the role of cognitions in the experience of guilt and posttrauma psychopathology.
