ARE PERSONALITY ASSESSMENTS VALID IN ACUTE MAJOR DEPRESSION

A number of recent studies indicate that identification of Axis II comorbidity in depressed patients may influence both the initial treatment plan and subsequent prognosis. Nevertheless, the validity of personality disorder diagnoses may be compromised by the effects of the patients' depression on historical recall, which distort presentation of their premorbid strengths and liabilities. These problems are illustrated in this study of 53 acutely depressed unipolar outpatients, with (N = 14) or without (N = 39) personality disorder diagnoses as defined by the Personality Disorder Examination (PDE). We found that: 1) pretreatment PDE diagnoses had no significant associations with any measure of demography, symptomatic status, illness course, or treatment response; and 2) pretreatment PDE diagnoses typically were not confirmed when patients were reassessed following effective treatment with cognitive behavior therapy. These findings provide strong empirical support for the wisdom of deferring definitive assessment of Axis II until an acute depressive disorder has been optimally treated.
