Psychometric Properties of the Modified Posttraumatic Stress Disorder Symptom Scale among Women with Posttraumatic Stress Disorder and Substance Use Disorders Receiving Outpatient Group Treatments.

ABSTRACT: The use of psychometrically sound measures to assess and monitor PTSD treatment response over time is critical for better understanding the relationship between PTSD symptoms and Substance Use Disorder (SUD) symptoms throughout treatment. We examined the psychometric properties of the Modified Posttraumatic Stress Disorder (PTSD) Symptom Scale, Self-Report (MPSS-SR). Three hundred fifty three women diagnosed with co-occurring PTSD (full or sub-threshold) and SUD who participated in a multisite treatment trial completed the MPSS-SR at pre-treatment, weekly during treatment, and posttreatment. Reliability and validity analyses were applied to the data. Internal consistency was excellent throughout the course of the trial demonstrating the MPSS-SR's high reliability. Strong correlations betwe
