Type D personality

a “distressed” personality pattern, characterized by a high degree of negative affectivity (i.e., a tendency to experience negative emotions) in combination with a conscious tendency to suppress self-expression in social interaction (see social inhibition). Accumulating evidence suggests that Type D individuals are at increased risk of developing coronary heart disease and other chronic medical conditions. [elaborated by Belgian medical psychologist Johan K. L. Denollet (1957–  )]
