Overview

Summary Health-related behaviours contribute to the global burden of cardiovascular disease (CVD). Cardiovascular imaging can be used to screen asymptomatic individuals for increased risk of CVD to enable earlier interventions to promote health-related behaviours to prevent or reduce CVD risk. Some theories of behaviour and behaviour change assume that engagement in a given behaviour is a function of individual threat appraisals, beliefs regarding the performance of behaviour, self-efficacy for performing the desired behaviour and/or dispositions to act (e.g. behavioural intentions). To date, little is known about the impact of cardiovascular imaging interventions on these constructs. This article summarises evidence related to perceived threat, efficacy beliefs, and behavioural intentions after CVD screening. We identified 10 studies (2 RCTs and 8 non-randomised studies, n = 2498) through a combination of screening citations from published systematic reviews and meta-analyses and searching electronic databases. Of these, 7 measured behavioural intentions and perceived susceptibility and 3 measured efficacy beliefs. Findings showed largely encouraging effects of screening interventions on bolstering self-efficacy beliefs and strengthening behavioural intentions. Imaging results that suggest the presence of coronary or carotid artery disease also increased perceived susceptibility to CVD. However, the review also identified some gaps in the literature, such as a lack of guiding theoretical frameworks and assessments of critical determinants of health-related behaviours. By carefully considering the key issues highlighted in this review, we can make significant strides towards reducing CVD risks and improving population health. Lay Summary This systematic narrative review sought to comprehensively report evidence related to individual responses to cardiovascular screening interventions. Theoretically, the study builds upon theories based on the cognitive perspective (e.g. Health Belief Model, Protection Motivation Theory), which supports the examination of individual perceptions of negative health-related outcomes or health risk, beliefs regarding the performance of a behaviour or outcome expectancies (e.g. perceived benefits of behavioural performance), personal control or capacity to perform a behaviour and/or willingness to invest the effort to engage in behaviour after behavioural intervention delivery. These concepts are considered key predictors of health-related behaviours and have been examined in several public health interventions. Using a variety of search strategies, studies that reported outcomes of interest were identified. Some studies showed that cardiovascular screening interventions may help people form the desired intention to engage in health-related behaviours. We also observed (largely) encouraging effects of cardiovascular screening interventions on individual confidence to engage in health-related behaviours and understanding of personal health risks. However, we identified some limitations in the design, delivery and outcomes assessed in the studies included. For future research, key recommendations to inform the design and delivery of health behaviour interventions are provided.
