We implemented an Appreciative Inquiry (AI) intervention to assist people with hypertension improve diet, physical activity, and blood pressure. In a two-group randomized controlled trial conducted over 12 weeks, 50 participants were recruited at an urban outpatient health care clinic. The intervention used participants' high peak positive experiences to promote behavior change, during two face-to-face individual sessions and three coaching telephone calls. Data were analyzed using test of differences between groups and analysis of covariance controlling for confounding variables. The intervention group had significantly higher levels of ideal self, positive emotions, and self-efficacy for chronic disease management than the control group. No significant group differences in physical activity, diet, or blood pressure. Findings provide empirical evidence about the underlying processes by which AI may promote health behavior change. Future research should examine the effectiveness of this AI intervention in a larger sample of patients and over a longer intervention period.
