Abstract
Many individuals diagnosed with a substance use disorder are also diagnosed with another psychiatric disorder. Little is known regarding which treatments are efficacious for these dually diagnosed individuals (DDI). Characterizing the psychometric properties of assessments used with DDI samples is essential to efficacy studies with DDI. This study examined the internal consistency and test-retest reliability of self-report instruments among DDI. Most subscales demonstrated high test-retest reliability; one subscale demonstrated poor reliability. Internal consistency was similar to that of non-DDI samples. This exploratory study suggests that, while some instruments should be interpreted cautiously, DDI samples can be accurately assessed with self-report measures.
