Personality disorders improve in patients treated for major depression
ABSTRACT To examine the stability of personality disorders and their change in response to the treatment of major depression.
149 depressed out-patients taking part in a treatment study were systematically assessed for personality disorders at baseline and after 18 months of treatment using the SCID-II.
Personality disorder diagnoses and symptoms demonstrated low-to-moderate stability (overall kappa = 0.41). In general, personality disorder diagnoses and symptoms significantly reduced over the 18 months of treatment. There was a trend for the patients who had a better response to treatment to lose more personality disorder symptoms, but even those who never recovered from their depression over the 18 months of treatment lost, on average, nearly three personality disorder symptoms.
Personality disorders are neither particularly stable nor treatment resistant. In depressed out-patients, personality disorder symptoms in general improve significantly even in patients whose response to their treatment for depressive symptoms is modest or poor.

ABSTRACT: The Minor Melancholia Mood Checklist (MMCL-32) was developed to identify sub-threshold states of major depression. The MMCL-32 can be considered as the counterpole to the Hypomanic Check List (HCL-32). Principal component analysis (PCA) without rotation was used to identify a bidirectorial principal component. To evaluate the clinical validity of the bidirectorial factors, with reference to brief recurrent depression, the Bech-Rafaelsen Melancholia Scale was used. We included 59 patients with bipolar I disorder (SCID criteria) and 57 patients with unipolar depression (more than one major depressive episode without hypomanic or manic episodes). They were all outpatients, but had recently been discharged from inpatient treatment. The PCA identified two contrasting factors: 17 items with negative loadings (psychasthenic depression factor) and 15 items with positive loadings (cognitive depression factor). When PCA was applied exclusively to the bipolar patients, 5 items within the cognitive factor were identified. When applied exclusively to the unipolar patients, 5 items within the psychasthenic factor were identified. The non-remitted bipolar patients scored higher on the cognitive factor (P=0.01) than the remitted. On the psychasthenic factor (P=0.06), the non-remitted unipolar patients scored higher than the remitted patients. The MMCL-32 was found psychometrically valid in measuring sub-threshold states of major depression with rather specific factors for bipolar and unipolar depression. Focusing on these factors could be a clinical aid to distinguish patients at risk of developing a bipolar course.Journal of Affective Disorders 03/2012; 137(1-3):79-86.

ABSTRACT: Assessment of personality disorders during the acute phase of major depression may be invalidated by the potential distortion of personality traits in depressed mood states. However, few studies have tested this assumption. We examined the stability of personality disorder diagnoses during and then after a major depressive episode (MDE). Subjects with major depression (N = 82) completed the 17-item Hamilton Depression Scale (HAM-17) and the Structured Clinical Interview for Axis II both at baseline during an MDE and at 3-month follow-up. We compared subjects who continued to meet DSM-IV criteria for the same Axis II diagnoses with patients whose diagnosis changed and patients with no DSM-IV personality disorder to determine the relationship to major depression and its severity. Sixty-six percent of subjects met DSM-IV criteria for at least one Axis II diagnosis at baseline and 80% had the same personality disorder diagnoses at follow-up. Thirty-four percent had a full remission of MDE at 3-month follow-up. Instability of Axis II diagnosis was associated with number of Axis II diagnoses at baseline (p = .036) and Hispanic ethnicity (p = .013). HAM-17 score change was unrelated to differences in the number of symptoms of personality disorders from baseline to follow-up, nor was remission from MDE on follow-up. Axis II diagnoses in acutely depressed patients reassessed after 3 months are often stable and not associated with remission of or improvement in major depression.The Journal of nervous and mental disease 06/2012; 200(6):526-30.
