Objectives: The purpose of this study was to test the construct validity of the Type D personality scale (DS14).
Methods: The DS14 and other personality scales, which have good construct validity (MMPI-2), TCI-RS, MBTI, NEO-PI-R) were administered to 151 college students. Correlation and regression analyses were performed to evaluate the validity of the DS14.
Results: There were significant positive correlations between the DS14 total score and scores on the F, D, Pa, Pt, Sc, Si and ’negative emotionality’ scales (MMPI-2), the ’harm avoidance’ scale (TCI), the ’neuroticism’ scale (NEO-PI-R), and the ’introversion’ scale (MBIT). Additionally, there were significant negative correlations between the DS14 total score and extroversion, agreeableness, openness to experience, cooperativeness, and reward dependence scales. Stepwise regression analysis also showed coherent RESULTS: negative emotionality, introversion, RCd and RC2 (MMPI-2), harm avoidance (TCI), neuroticism (NEO-PI-R), introversion, thinking (MBIT) scales were selected as significant explanatory variables.
Conclusion: Individuals with a Type-D personality, as assessed by the DS14, seem to have a tendency to experience negative emotions such as depression and anxiety. As a construct, Type-D personality also seems to be closely related to neuroticism and introversion. These results indicate that the DS14 has sound construct validity as a screening tool for measuring stress-vulnerability traits, that is to say, type-D personality.
