Active Choice Regarding Cardiovascular Disease Risk

Cardiovascular Diseases Clinical Trial

Official title: Actively Choosing How to Cope With an Increased Risk of Cardiovascular Disease: A Randomised Web-Based Experiment

Status Completed

Clinical Trial Summary

In this web-based RCT, the investigators will investigate whether promoting an active choice regarding coping with an increased CVD risk results in better psychological outcomes (e.g., degree of active choice; commitment toward the chosen option) compared to usual care (i.e., a GP's advice to change one's lifestyle and take medication). By 'active choice' the investigators mean a conscious and autonomous choice in which an individual (a) becomes aware of a discrepancy between the current and desired situation; (b) understands what his/her CVD risk means, and what its causes and consequences are; (c) evaluates the pros and cons of the different options to cope with the risk; and (d) is clear about his/her values regarding the choice. The different options to cope with an increased CVD risk include: changing one's lifestyle; taking medication; doing both; or changing nothing.

Clinical Trial Description

Cardiovascular disease (CVD) continues to be a leading cause of mortality among adults. Adults at increased risk of cardiovascular disease are usually advised by their general practitioner (GP) to change their lifestyle (i.e., quit smoking; eat healthier; become more physically active). In addition, GP's regularly advice their patients to take antihypertensive and/or lipid lowering medication to decrease the CVD risk. Previous research has shown that many patients at increased risk of CVD have difficulty maintaining lifestyle changes and adhering to their medication regimen - either intentionally or unintentionally. Intentional non-adherence could occur when patients experience side-effects of the medication, whereas unintentional non-adherence usually occurs when patients forget to take their medication.

In the current study, the investigators will investigate whether promoting an active choice regarding coping with an increased CVD risk results in better psychological outcomes (e.g., degree of active choice; commitment toward the chosen option) compared to usual care (i.e. a GP's advice to change one's lifestyle and take medication). By 'active choice' the investigators mean a conscious and autonomous choice in which an individual (a) becomes aware of a discrepancy between the current and desired situation; (b) understands what his/her CVD risk means, and what its causes and consequences are; (c) evaluates the pros and cons of the different options to cope with the risk; and (d) is clear about his/her values regarding the choice. The different options to cope with an increased CVD risk include: changing one's lifestyle; taking medication; doing both; or changing nothing.

The investigators will investigate this in a web-based RCT among adults aged 45-65 years. The intervention group (i.e. active choice group) and control group (i.e. usual care group) will both receive a hypothetical CVD risk. The investigators expect an active choice regarding coping with an increased CVD risk to result in better psychological outcomes compared to a GP's advice. Ultimately, a more active choice is expected to results in greater behavioural persistence regarding the chosen option; i.e. lifestyle change and/or medication adherence. ;
