Purpose: The purpose of this study was to verify the validity and reliability of the Type D Scale-14 (DS14).
Methods: The participants were 288 patients who were diagnosed with angina pectoris, myocardial infarction, and hypertension. DS14 was developed by Denollet(2005) and consists of two domains, 7 items on negative affectivity (NA) and 7 items on social inhibition (SI). The Korean version of DS14 was developed through translation-reversed translation and a preliminary test. Data were collected using a self-report questionnaire. Cronbach and Guttman split-half were used to test reliability and item analysis and factor analysis for validity. The SPSS program was used.
Results: 35.8% of the participants were classified as Type D. Mean score for NA was 16.80 and for SI, 14.10 in Type D participants. For reliability of NA, Cronbach =0.771, and for SI, 0.707. Factor analysis on 12 items(numbers 1 & 3 were excluded as the corrected item-total correlations were below r=0.3) yielded two factors for NA (6 items) and SI (6 items). Number 7 in the NA domain was sorted into the SI domain.
Conclusion: The results indicate, the cultural differences were between Europeans and Koreans. Repetition of the research is needed for generalization of DS14.
