After screening, 111 patients were identified as Type D personality, and finally, statistical data obtained from these questionnaires were analyzed.
Results: The results obtained from regression analysis showed that type D personality has positive and significant relationship with variables of behavioral inhibition system and fight-flight and freeze system, and had negative significant corelation with behavioral activation system. Also, regression analysis results showed that type D personality had a positive and significant associated with latent anxiety in students.
Conclusion: According to research findings, determining the exact position of type D personality in personality systems which are based on bio-behavioral model, increase our understanding of mechanisms underlying properties of type D personality, emotions and emotional response
