The Swedish version of the Outcome Questionnaire (OQ‐45): Reliability and factor structure in a substance abuse sample

This study described the psychometric properties of the Swedish version of the Outcome Questionnaire (OQ-45.2) in a substance abuse sample (N=227). The test properties were satisfactory except for somewhat low internal consistency in the social role subscale. The results were similar to those obtained in other countries but systematic international comparisons are still lacking.
