This correlational study attempted to determine if the Outcome Questionnaire can be used to collect the same information as the Revised Dyadic Adjustment scale in marital assessment. Both measures are common pretreatment assessments and have relational components. The study used secondary data from the Utah State University Marriage and Family Therapy Clinic. Reliability and correlational tests were performed and the results indicate that the assessments measure different constructs. There also were no statistically significant correlations when comparing the measures by gender, marital distress, and marital satisfaction. Implications are discussed including the formulation of new clinical cut-off scores and the importance of using both measures to perform better assessments.
