Background: Type D personality is a risk indicator in cardiac patients. While both the validity and reliability of the Type D scale (DS14) have been confirmed in Western Europe, less attention has been paid to the subject in other nations.
Purpose: The purpose of this study was to examine the validity of the Hebrew version of the DS14 among a sample of cardiac patients in Israel.
Method: Male patients (N = 94) hospitalized for a first acute coronary syndrome (ACS) completed the DS14 1 month after their ACS. The Brief Symptoms Inventory (BSI) scales for depression and anxiety and the Buss-Durkee Hostility Inventory-Dutch for measuring covert and overt aggressions were administered during the initial hospitalization (baseline). The BSI was administered again at the 6-month follow-up. At follow-up, patients were also asked about their participation in a formal cardiac rehabilitation program.
Results: The two-factor structure of the DS14 was confirmed and the DS14 subscales were internally consistent (Cronbach's α = 0.79/0.80). Type D cardiac patients had a significantly higher mean score on anxiety, depression, and covert aggression at baseline compared to non-Type D patients. At the 6-month follow-up, Type D was associated with more anxiety, more depression, and less attendance at a formal cardiac rehabilitation program. The prevalence of Type D in the current sample (5.3%) was found to be significantly lower than elsewhere in Europe.
Conclusion: Preliminary evidence suggests that it is possible to use the Hebrew version of the DS14 among Hebrew-speaking cardiac patients in future studies. However, the prevalence of the Type D personality in Israel should be further assessed.
