Validation of the Persian Version of the Adherence to a Healthy Lifestyle Questionnaire in Patients with Cardiac Syndrome X

Aims and objectives: The objective of the present study is to assess the reliability and validity of the Persian version of the Adherence to a Healthy Lifestyle Questionnaire (AHLQ) between Iranian patients with Cardiac Syndrome X (CSX).

Background: The burden of cardiac heart disease and related conditions remains high, with rates of hospitalization disability and cost on the rise. In addition, angina without coronary artery disease (CAD) has substantial morbidity and is present in 20% to 30% of patients undergoing angiography Adherence to a combination of healthy lifestyle factors has been shown to be related to a considerable reduction of cardiovascular risk.

Design: A Cross -sectional survey was used.

Methods: 100 Iranian patients, who referred to the Tehran Heart Center hospital, were recruited by randomized sampling. All the patients fulfilled the AHL questionnaire. Responses were analysed via exploratory factor analysis using primary elements analysis with varimax orthogonal rotation. The internal conformity reliabilities of the overall scale and its subscales were estimated via Cronbach's alpha coefficient. The reliability of the AHLQ was assessed for internal consistency and testretest reliability.

Result: The AHLQ variables are classified into six domains. Cronbach's alpha coefficient for each subscale was used to check the reliability of each scope. The reliability of each subscale was confirmed by Cronbach’s alpha. The level of significance was evaluated at P < 0.05. The tool has shown satisfactory validity.

Conclusions: The Persian version of the AHL questionnaire is suitable to be used for Iranian patients with CSX disease or atherosclerosis. In addition, the AHLQ is a reliable and valid tool and could be used for evaluation of adherence to a healthy lifestyle in clinical research for Iranian patients with cardiovascular diseases.
