The purpose of this study was to evaluate the reliability and validity of the Cardiac Event Threat Questionnaire (CTQ). The CTQ is a 31-item instrument specific for cardiac events that was developed from a literature review and self-reports of persons who had experienced a recent cardiac event. A convenience sample (N = 270) of persons hospitalized for angina, myocardial infarction, or cardiac surgery completed the CTQ. Satisfactory internal consistency and test-retest reliabilities were found. Results of confirmatory factor analysis and correlation with the Profile of Mood States provide initial support for construct validity of the CTQ.
