RESULTS: Nineteen percent of patients (n=572) had a Type D personality. The perceived receipt of disease-specific (mean 46 vs. 51), medical test (56 vs. 63) and treatment information (37 vs. 42) was significantly lower for Type D patients compared with non-Type Ds as assessed with the EORTC QLQ-INFO25 (scales 0-100; all ps<0.01). Cancer patients with a Type D personality were less satisfied with the received information (49 vs. 58; p<0.01) and found the received information less useful (55 vs. 61; p<0.01) compared with non-Type Ds. Multivariate linear regression analyses showed that Type D personality was independently associated with information about the disease (Beta=-0.09), medical tests (Beta=-0.12) and treatment (Beta=-0.08), and with satisfaction with information received (OR=0.54; 95%CI=0.44-0.66;all ps<0.01). CONCLUSIONS: This study showed that patients with a Type D personality perceived that they received less information and reported less satisfaction with the amount of received information as compared with non-Type D patients.
