The ABCD Risk Questionnaire: Further Evidence of Validity and Reliability Using a Facebook Sample (Preprint)
BACKGROUND Cardiovascular disease (CVD) is the leading cause of death globally with more than 17 million deaths reported worldwide in 2015. Recently, the ABCD Risk Questionnaire was developed as a concise, validated and easy to use questionnaire, using participants attending the National Health Service (NHS) Health Check program in the United Kingdom. Since its development, it is yet to be used in the general population online or offline to provide further evidence of its validity and reliability. OBJECTIVE This study investigated the construct validity and reliability of the ABCD Risk Questionnaire and compared cardiovascular disease knowledge, perception of risk, perceived benefits of behaviour change and healthy eating intention between urban and rural dwellers. METHODS A cross-sectional survey that recruited Tasmanian residents aged 18 years or older. RESULTS With the exception of the cardiovascular disease knowledge subscale, all other subscales demonstrated acceptable values for both construct validity and reliability analyses. Rural dwellers had a higher perceived risk of heart attack and stroke (19.45 versus 18.42; p<0.001) compared to urban dwellers. No significant differences were observed for cardiovascular disease knowledge, perceived benefits of behaviour change, and healthy eating intention. CONCLUSIONS This study provides evidence supporting the validity and reliability of the subscales of the ABCD Risk Questionnaire. This suggest that the questionnaire can be used in the general population in an online environment, and in the development of educational materials. The study also provided preliminary evidence that the perceived personal risk of heart attack and stroke is higher in rural compared to urban dwellers in Tasmania. Further studies using a random sample from the population is required. Further testing of the ABCD Risk Questionnaire against the Pooled Cohort Risk Equation for estimating atherosclerotic CVD risk (2013 PCE‐ASCVD) or the 1991 Framingham model is also recommended. This may be useful in planning and developing online health initiatives for cardiovascular disease.
