Construct validity of the Diagnostic Inventory of Personality and Symptoms: external correlates.

This study extended knowledge of the construct validity of Vincent's Diagnostic Inventory of Personality and Symptoms (DIPS) by examining the relationships between the DIPS and the MMPI, the Millon Clinical Multiaxial Inventory, the Profile of Mood States, the Symptom Check List-90, and the California Psychological Inventory. Subjects were 300 predominantly male psychiatric inpatients. Correlational analyses revealed that the DIPS clinical scales were related most strongly to MMPI and MCMI clinical scales. Eleven of 14 DIPS clinical scales showed clinically significant correlations with similar scales of the external measures. The validities of the Stress-Adjustment Disorders and Psychological Factors Affecting Physical Condition scales were not ascertained directly.
