Type D personality, physical symptoms and subjective stress: the mediating effects of coping and social support.

Coping style and social support may represent mechanisms to explain the relationship between Type D personality and ill-health. This study investigated whether Type D is associated with physical symptoms and perceived stress in a non-cardiac population, and if these relationships are mediated by coping and social support. In a cross-sectional study, 304 participants (110 males, mean age 22.1 years) completed measures of Type D, physical symptoms, coping, perceived stress and social support. Results showed that Type D, the interaction of negative affectivity and social inhibition (NA × SI), was positively correlated with physical symptoms, perceived stress, and avoidant coping, and negatively correlated with social support, problem-focused coping and emotion-focused coping. A series of bootstrapped multiple mediator tests showed that social support and avoidant coping fully mediated the relationship between Type D and physical symptoms. Furthermore, social support and emotion-focused coping partially mediated the relationship between Type D and perceived stress. These findings demonstrate for the first time that Type D personality is associated with physical symptoms in a non-cardiac population. Social support and coping style represent mechanisms that can, in part, explain the relationship between Type D and physical symptoms, and Type D and perceived stress.
