Multimethod Validity Assessment of the SWAP-200 Dysphoric Q-Factor.

The aim of this study was to investigate the convergent validity of the Shedler-Westen Assessment Procedure Q-Sort Dysphoric Q-Factor with scales from the therapist, the patient, and independent observers. Therapists used the Shedler-Westen Assessment Procedure Q-Sort to describe their patients after the therapeutic assessment and the first two therapy sessions (when available). Independent observers completed a number of symptom distress, global functioning, and Axis II psychopathology measures after watching videotapes of the therapeutic assessment. They also completed a measure of social cognition and object relations after watching videotape of the therapeutic assessment and the first two therapy sessions (when available). Patients completed measures of symptomatology and personality assessment. Results indicated several significant correlations between the Dysphoric Q-Factor and a number of the clinician ratings of depressive symptomatology. In addition, three clinician ratings (Personality Disorder Index, Global Assessment of Functioning scale, and the experience and management of aggressive impulses variable of the Social Cognition and Object Relations Scale) demonstrated unique and nonredundant predictive ability in accounting for the variance of the Dysphoric Q-Factor. The patient self-report measures, however, did not correlate significantly with the Dysphoric Q-Factor, although several correlations demonstrated trends toward statistical significance.
