Insights
The Cardiac Event Threat Questionnaire (CTQ) reliably measures patient concerns after a cardiac event. This study confirms its validity for assessing psychological responses to heart conditions.
Area of Science:
- Cardiology
- Psychological Medicine
- Health Psychology
Background:
- Cardiac events like myocardial infarction significantly impact patient well-being.
- Assessing patient threat perception is crucial for recovery and management.
- Existing instruments may not fully capture the nuances of cardiac event-related anxiety.
Purpose of the Study:
- To evaluate the reliability and validity of the Cardiac Event Threat Questionnaire (CTQ).
- To establish the CTQ as a dependable tool for measuring patient threat perception following cardiac events.
Main Methods:
- The study involved 270 participants hospitalized for angina, myocardial infarction, or cardiac surgery.
- Participants completed the 31-item Cardiac Event Threat Questionnaire (CTQ).
- Internal consistency, test-retest reliability, confirmatory factor analysis, and correlation with the Profile of Mood States were assessed.
Main Results:
- The Cardiac Event Threat Questionnaire (CTQ) demonstrated satisfactory internal consistency.
- Test-retest reliability for the CTQ was found to be reliable.
- Confirmatory factor analysis and correlation analyses provided initial support for the construct validity of the CTQ.
Conclusions:
- The Cardiac Event Threat Questionnaire (CTQ) is a reliable and valid instrument for assessing threat perception in cardiac patients.
- The CTQ can be utilized effectively in clinical and research settings for patients experiencing cardiac events.
- Further research can explore the CTQ's utility across diverse cardiac populations and its predictive value for outcomes.
Abstract:
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.
