Abstract:
Objective: Type D personality, tendency trait to experience increased NA
(Negative Affect) and SI (Social Inhibition) has been associated with negative
psychological conditions linked to heart disease. This study aimed to examine the
psychometric properties of the Malay version of Type D personality scale (DS14)
among Malaysian patients with coronary artery disease (CAD). Methods: In this
cross-sectional study 195 patients diagnosed with CAD were selected from
National Heart Institute, Kuala Lumpur. They completed the questionnaire
including demographic information and the Malay version of DS14 and Hospital
Anxiety and Depression Scale (HADS). Results: The structural validity, as
demonstrated by exploratory factor analysis of the DS14 was acceptable. The
Cronbach's α coefficient for the NA and SI subscales were 0.876 and 0.732,
respectively. With the standardized cut-off of NA ≥ 10 and SI ≥ 10, 28.2% of the
patients with CAD were defined as having a Type D personality. Anxiety was
significantly higher among patients with Type D personality. Conclusion: The
results indicate that the Type D personality (DS14) questionnaire is a valid and
reliable tool in the Malaysian population. The prevalence of Type D personality
in Malaysia falls close to what has been found in Western countries, at least for
CAD patients. This study indicates also that it is possible to use the DS14 among
the Malaysian population in future cross-cultural studies.
