The present study aimed to investigate the relationship between type D personality and sensitivity to reinforcement and latent anxiety in students with type D personality.
Materials and Methods: For this purpose, 600 students (240 boys and 360 girls) from various faculties of Persian Gulf University who were studying in 2013-2014 academic year, were selected randomly using cluster sampling stage, completed type D personality scale, Jackson sensitivity to reinforcement (2009) and Spielberger Anxiety Inventories (1970). After screening, 111 patients were identified as type D personality, and finally, statistical data were analyzed through regression analysis.
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 correlation 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 the 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.
