The Relationship between Type D Personality and Multidimensional Health Locus of Control among University Students Population

Type D personality is predictive of adverse clinical outcome and psychological distress in cardiac patients. The mechanisms by which type D personality influences health are largely unknown. The aim of this study is to investigate the relationship between type D personality and the health locus of control. A sample of 588 students (370 females and 218 males) were selected, according to the cluster random sampling method, from the students of Tabriz University and were asked to complete a questionnaire about type D personality and Multidimensional Health Locus of Control. Research data were analyzed by statistical methods of Pearson correlation and stepwise regression analyses. The results showed that, through dimensions of Health Locus of Control, only the relationship between negative affect and social inhibition with health locus of control of powerful others were positive and statistically significant. Also, regression analysis showed that components, such as negative affect and social inhibition were good predictors for health locus of control of powerful others. Based on these findings, we conclude that people with type D personality have high health locus of control of powerful others; and both dimensions, i.e., negative affect and social inhibition, are correlated with high powerful others’ health locus of control.
