Reliability and Validity of the Outcome Questionnaire–45.2

Abstract

A random sample of 220 counseling center client records at a large Midwestern university, was used to assess reliability and validity of the Outcome Questionnaire–45.2 (OQ–45.2). The center uses the OQ–5.2 at intake. Internal consistency coefficients for the three subscales and the total score were acceptable, with high coefficients for the total score and Symptom Distress subscale and moderate coefficients for the Interpersonal Relations and Social Role subscales. Correlations among clients' presenting concerns and OQ–5.2 scores were computed and lend strong support for the validity of the OQ–45.2 total score and the Symptom Distress subscale. Weaker support was found for the Interpersonal Relations and Social Role subscales.
