The Traumatic Stress Institute Belief Scale as a Measure of Vicarious Trauma in a National Sample of Clinical Social Workers

Abstract

This article reports on a study of convergent and discriminant validity of the Traumatic Stress Institute Belief Scale (TSI)–Revision L (Traumatic Stress Institute, 1994) as a measure of vicarious trauma in a random sample of master's level clinical social workers. Forty-nine items from six subscales of the TSI were used. The scale purports to measure disturbed beliefs that may be caused by direct traumatic experience or repeated exposure to details of clients' traumatic stories. Results of correlational analyses of the TSI score with study variables and exploratory multiple regression analysis on the TSI score indicate its association with younger age, more reported somatic symptoms, lower annual salaries, lower scores on the Perceived Social Support (PSS)–Friends subscale (Procidano & Heller, 1983) and greater burnout as measured by the Maslach Burnout Inventory (Maslach & Jackson, 1986). TSI scores were not associated with social workers' personal trauma history, their reported weekly amount of face-to-face client contact, or a self-report of the level of intrusiveness of client material into the social workers' lives. TSI scores appear to be measuring perceptions about self and work that, like burnout, may relate to social workers' general outlook, not necessarily to the effects of traumatic stress, vicarious or otherwise. Significant overlap of the TSI with burnout scores in this social work sample suggests a lack of clear distinction between burnout and vicarious trauma.
