This study examined whether the Outcome Questionnaire—45 (OQ) and its subscales assessed unique interpersonal distress. The Inventory of Interpersonal Problems (IIP) was used to assess discriminant validity for unique interpersonal distress. Participants (N = 121) were recruited from a southwestern university counselor training center. Significant correlations emerged between OQ and IIP scores supporting the OQ as a measure of general interpersonal distress. However, the OQ subscales do not significantly assess unique types of interpersonal distress.
