Study published: Evaluation of instrument to assess cardiac anxiety
In a study recently published in BMC Medical Research Methodology, the researchers evaluate the Cardiac Anxiety Questionnaire (CAQ) - a questionnaire used to assess cardiac anxiety, and whether the questionnaire is suitable to apply to a Swedish population.

Cardiac anxiety (CA) is the aspects of anxiety related to fear of heart malfunctioning, for example, exaggerated attention to the heart rate or avoidance of activities that would lead to a higher heart rate. It is common that people who have experienced a myocardial infarction (MI) also experience CA, which, in its turn, is associated with an increased risk for a recurrent cardiac event. The most common way to measure CA is through CAQ.
This study aims to test and evaluate different divisions of sub-categories of the questionnaire that have been proposed through previous research. The researchers also sought to test the reliability and validity of a Swedish translation of the questionnaire. 930 patients who have experienced an MI were asked to fill in the CAQ. The data were analysed using factor analysis.
The researchers found that the Swedish translation of the questionnaire maintains similar qualities as the original and that the questionnaire, with a few modifications, is a suitable instrument to assess cardiac anxiety among Swedish patients.
