This study investigated the role of Type D personality in health behaviors and perceived social support in individuals with coronary heart disease. Different from other related studies, this study assessed a broader range of health behaviors in an eastern population while controlling for anxiety and depression. In all, 386 Indonesian individuals with coronary heart disease completed the measures assessing Type D, perceived social support, depression, anxiety, and health behaviors. Compared with non-Type D, Type D individuals reported more unhealthy behaviors, less healthy behaviors, and perceived less social support. For those identified as Type D, tailored interventions might be considered.
