This study assessed the factor structure, internal consistency, test-retest reliability, and construct validity of the Problems Assessment for Substance Using Psychiatric Patients (PASUPP; Carey, Roberts, Kivlahan, Carey, & Neal, 2004) with a sample of 278 men and women seeking outpatient dual-diagnosis treatment. All participants were diagnosed with a current AUD and schizophrenia and/or bipolar disorder. Initial confirmatory factor analysis did not support the 1-factor model for the 50-item measure found by Carey and colleagues. Instead, exploratory factor analysis yielded a shorter (27-item) scale with four distinct, yet related factors (Physical Problems, Aggression, Social and Financial Consequences, and Psychological Problems). The factor-based scales had good internal consistency (α = .77-.81) and 1-week test-retest reliability (r= .67-.73). The revised PASUPP (PASUPP-R) was associated with measures of psychiatric symptoms/adjustment, substance use/dependence, and another measure of substance use problems, providing evidence for convergent validity. Subgroup comparisons suggested few demographic differences on the PASUPP-R, but differential patterns of problems endorsement emerged as a function of mental health and substance use diagnosis. Overall, this study provides preliminary evidence for the psychometric soundness of the PASUPP-R as a measure of problems experienced by persons with co-occurring psychiatric and substance use disorders.
