Intrusion was operationalized as Post traumatic Stress Disorder symptom severity, depressive symptom severity, social conflict, and financial strain. We measured Posttraumatic Stress Disorder symptom severity using the total score on the 17-item Davidson Trauma Scale . Scores greater than 40 are consistent with a clinical diagnosis of PTSD. Depressive symptom severity was measured with The Center for Epidemiologic Studies-Depression (CES-D) 20-item scale . Total scores greater than 16 are consistent with symptoms of clinical depression. Social conflict, perceived discord within relationships, was measured using the 13-item subscale from the Interpersonal Relationship Inventory . The total score of the Financial Strain Index was used to measure level of financial strain. Internal consistency was greater than . 80 on all measures at baseline, 6 months, and 12 months, except for the Mastery Scale, for which Cronbach alpha was .78, .69, and .77 respectively.
