Psychometric properties of the Swedish cardiac anxiety questionnaire: a Rasch analysis.

ABSTRACT: Cardiac anxiety (CA) is a commonly occurring condition in populations with both cardiac and mental health conditions. It is assessed using the CA questionnaire (CAQ), which has been translated to several languages and its validity and reliability has been investigated using classical test theory. The factor structure of the CAQ remains uncertain, and no study has investigated the psychometric properties of the CAQ using modern test theory approaches. The aim of this study was to use Rasch analysis to test the validity and reliability of the original 18-item CAQ in a Swedish sample of patients with myocardial infarction, as well as other scales, based on previous findings. Participants were 754 patients after myocardial infarction with preserved cardiac function. Data were fitted to the Ras
