OBJECTIVE - The aim of this study was to evaluate the relationship between poor metabolic control and maladaptive personality traits (according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised) in an adult-onset insulin-dependent diabetes mellitus sample group (n = 77). RESEARCH DESIGN AND METHODS - Metabolic control was evaluated through glycosylated hemoglobin (HbA(1c)). Personality traits were assessed with the Personality Diagnostic Questionnaire-Revised, a self-administered questionnaire. Residual pancreatic secretion (fasting serum C-peptide) was also evaluated. RESULTS - Principal components analysis revealed three personality profile: 'withdrawn-suspicious' (P1), 'dramatic-dependent' (P2), and 'aggressive-irresponsible' (P3). Multiple linear regression analysis showed that C-peptide levels and P2 personality profiles were significant and independent predictors of HbA(1c) plasma levels: P2 predicted high HbA(1c) values and C-peptide predicted low HbA(1c) levels. CONCLUSIONS . These data suggest that a P2 personality profile is a significant predictor of poor metabolic control.
