Type D personality is associated with increased comorbidity burden and health care utilization among 3080 cancer survivors.

OBJECTIVE: Cancer survivors often report comorbid diseases, but there are individual differences in risk. Type D personality is a general propensity to psychological distress that is related to poor cardiovascular outcomes. In this study, we examined whether type D was also related to comorbidity burden and health care utilization among cancer survivors.
METHODS: Individuals diagnosed with endometrial cancer or colorectal cancer between 1998 and 2007, or with lymphoma or multiple myeloma between 1999 and 2008 as registered in the Eindhoven Cancer Registry, received the Self-Administered Comorbidity Questionnaire, questions on health care utilization and the Type D personality scale; 69% (n=3080) responded.
RESULTS: Nineteen percent of survivors had a type D personality. Over a 12-month period, type D survivors significantly more often reported osteoarthritis, back pain, and depression than non-type D survivors. Also, type D survivors more often reported to feel bothered by high blood pressure, osteoarthritis, heart disease, depression, diabetes and lung disease during daily activities. Type D survivors more often visited their general practitioner than non-type D survivors (P<.001), also in relation to cancer (0 visits: 54% vs. 60%; 1-5: 28% vs. 22%; >5: 9% vs. 5%; P<.001), as well as their specialist (0 visits: 6% vs. 7%; 1-5 visits: 59% vs. 64%; >5 visits: 30% vs. 23%; P<.01).
CONCLUSION: Type D personality is a vulnerability factor that may help to identify subgroups of cancer survivors who are at an increased risk for comorbidity burden and increased health care utilization.
