Abstract

Purpose: Type D personality has been identified as an independent risk factor for survival in cardiovascular disease (CVD) patients. As CVD is present in about 50% of dialysis patients, it is of clinical interest to assess the prevalence of type D personality, the association with depressive and anxiety symptoms, and stability of type D personality in dialysis patients. Methods: Data was used from two consecutive measurements of the DIVERS study, a prospective cohort study among chronic dialysis patients in the Netherlands. Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and the Type D Scale-14 (DS14) were used to assess depressive and anxiety symptoms and type D personality, respectively. The association of type D personality was assessed with analysis of variance F test. Stability of type D personality, depressive, and anxiety symptoms were determined by calculating Cohen’s κ, and by determining the positive agreement. Results: In total, 349 patients were included of which 249 patients had two measurement points. The prevalence of type D personality was 21% and type D personality was associated with depressive and anxiety symptoms (P < 0.01). Over a 6-month period, Cohen’s κ was 0.52, 0.56, and 0.61 for type D personality, depressive, and anxiety symptoms, respectively. Sixty-one, 73, and 73% had a stable type-D personality, depressive, and anxiety symptoms, respectively. Conclusion: The presence of type D personality varies over time in dialysis patients. Therefore, type D personality is possibly more a state instead of a trait phenomenon.
