Patients with a congenital heart defect and type D personality feel functionally more impaired, report a poorer health status and quality of life, but use less healthcare.

Background: Type D personality, characterized by high levels of negative affectivity and social inhibition, is related to mortality, morbidity, poor health status, quality of life (QoL) and less healthcare utilization in various cardiovascular patient groups. To date, studies in patients with congenital heart disease (CHD) are lacking.

Aims: (1) To examine the prevalence of type D personality in CHD patients; (2) to compare type D to non-type D patients with regard to disease severity, functional status, health status and QoL; and (3) to examine the extent to which type D personality is independently related to healthcare utilization.
