THEORETICAL FRAMEWORK
The Motivational Interviewing [18] (MINT) intervention is informed by Motivational Enhancement Theory [18], which incorporates principles drawn from Self-Determination Theory [19,20], and Self-Efficacy Theory [21]. Figure 1 provides a conceptual model showing the links between the theoretical components, behavior change, and BP reduction. The model depicted shows that the effect of MINT on BP reduction is mediated through enhancement of patients’ self-efficacy and increased intrinsic motivation. Thus, patients who undergo MINT will benefit from increased self-efficacy and be more intrinsically motivated to adopt the recommended TLC. The adherence to therapeutic lifestyle behaviors will in turn lead to BP reduction.
