Objective:The association between Type D personality and the higher prevalence of hypertensive disease has been proved by empirical research. But the psychopathological mechanisms linking the disease course and Type D personality are largely unknown with autonomic imbalance is one of the candidates. Therefore, the purpose of this study is to examine the association between Type D personality and autonomic nervous system (ANS) reactivity during anger recall task among patients with hypertension disease.Method: The database collected by the projects supported by the grants from Ministry of Science and Technology(NSC 102-2410-H-194-022) to Chia-Ying Weng. The author served as a part-time research assistant in the project, and participated in parts of drafting the projects proposals, and collecting through survey administraction.Under the supervision and assistance of Chia-Ying Weng. Seventy- one (mean age = 55, SD 8.33 years; female=49.29% ) patients with hypertension were recruited from a general hospital in Taiwan. Type D personality was assessed by Type D Scale-14-Taiwanese version which includes two subscales, Negative affectivity (NA) and Social inhibition (SI).Participants underwent the anger recall task and their heart rate variety (HRV) was recorded during the following stages: baseline (B), anger recall (AR), anger description (AD), and recovery (R). Result:In male, the systolic and diastolic blood pressure (SBP: F(1,17)= 6.571, p< .05; DBP: F(1,17)= 6.920, p< .05) of participants with Type D personality was higher than that of the non-TD counterpart.In male, Social Inhibition was positively correlated with LF/HF ("β" = .511, p<.05) during recovery stage. In female, Negative affectivity was positively correlated with ln(HF) ("β" = .838, p<.01) during anger recall stage.Conclusion: The results of this study demonstrated that male hypertension patients with Type D personality perform higher blood pressure.The male hypertension patients with higher Social Inhibition trait showed the pattern of the sympathetic dominance during a 5-min period after anger elicited state, which might link Type D personality to the higher risk of poor prognosis of hypertensive disease.
