This study sought to examine the psychometric properties of a revised version of the SIP (SIP-R) as a measure of adverse consequences for alcohol and drug users in both English and Spanish-speaking populations. The English version was evaluated within a large population of alcohol and drug abuse treatment seekers (N=886) pooled from two national, multisite randomized trials (protocols CTN-0004 and -0005). It was also translated into Spanish and evaluated in a large population of Spanish-speaking substance abuse treatment seekers (N=405) participating in a separate multisite randomized trial (CTN-0021). All trials utilized a common assessment battery that included the ASI, the URICA, and a substance use calendar. Reliability and validity analyses included internal consistency, confirmatory factor analysis, and correlations. Differences in reported consequences were explored using ANOVA. For the English version, results supported the internal consistency and theoretical five-factor structure. Convergent validity was evident through strong correlations with the URICA and the drug composite score from the ASI, whereas weak correlations with other composite scores provided evidence of discriminant validity. Results for the Spanish version were highly similar, with strong internal consistency, factor structure, and a similar pattern of correlations with the ASI and URICA. In both the English and Spanish-speaking samples, baseline SIP-R total scores were higher for those not legally mandated to treatment and were associated with days retained in treatment.
Conclusions: This is the first study to evaluate the SIP-R within such a large, diverse sample of treatment seekers, including evaluation of a Spanish version. Both the English and Spanish versions of the SIP-R demonstrated strong psychometric properties and should be considered a valuable measure of adverse consequences associated with drug and alcohol use.
