Culturally appropriate storytelling to improve blood pressure: a randomized trial.

BACKGROUND: Storytelling is emerging as a powerful tool for health promotion in vulnerable populations. However, these interventions remain largely untested in rigorous studies. OBJECTIVE: To test an interactive storytelling intervention involving DVDs. DESIGN: Randomized, controlled trial in which comparison patients received an attention control DVD. Separate random assignments were performed for patients with controlled or uncontrolled hypertension. (ClinicalTrials.gov registration number: NCT00875225) SETTING: An inner-city safety-net clinic in the southern United States. PATIENTS: 230 African Americans with hypertension. INTERVENTION: 3 DVDs that contained patient stories. Storytellers were drawn from the patient population. MEASUREMENTS: The outcomes were differential change in blood pressure for patients in the intervention versus the comparison group at baseline, 3 months, and 6 to 9 months. RESULTS: 299 African American patients were randomly assigned between December 2007 and May 2008 and 76.9% were retained throughout the study. Most patients (71.4%) were women, and the mean age was 53.7 years. Baseline mean systolic and diastolic pressures were similar in both groups. Among patients with baseline uncontrolled hypertension, reduction favored the intervention group at 3 months for both systolic (11.21 mm Hg [95% CI, 2.51 to 19.9 mm Hg]; P = 0.012) and diastolic (6.43 mm Hg [CI, 1.49 to 11.45 mm Hg]; P = 0.012) blood pressures. Patients with baseline controlled hypertension did not significantly differ over time between study groups. Blood pressure subsequently increased for both groups, but between-group differences remained relatively constant. LIMITATION: This was a single-site study with 23% loss to follow-up and only 6 months of follow-up. CONCLUSION: The storytelling intervention produced substantial and significant improvements in blood pressure for patients with baseline uncontrolled hypertension.

A stories-based interactive DVD intended to help people with hypertension achieve blood pressure control through improved communication with their doctors.

OBJECTIVE: Our goal was to develop an interactive DVD to help African American and Caucasian American adults with hypertension learn how to become better communicators during medical interactions. Material was to be presented in several formats, including patients' narratives (stories). METHODS: To develop the narratives we recruited members of the target audience and elicited stories and story units in focus groups, interviews, and seminars. Story units were ranked-ordered based on conformance with the theory of planned behavior and narrative qualities and then melded into cohesive stories. The stories were recounted by actors on the DVD. RESULTS: 55 adults (84% women; 93% African American) participated in a focus group, interview, or seminar; transcripts yielded 120 story units. The most highly rated units were woven into 11 stories. The six highest rated stories/actor-storytellers were selected for presentation on the DVD. CONCLUSION: We achieved our goal of developing an easy-to-use, story-driven product that may teach adults how to talk effectively with their doctors about hypertension. The DVD's effectiveness should be tested in a randomized trial. PRACTICE IMPLICATIONS: Behavioral interventions aimed at improving patients' ability to communicate during doctor visits may be useful adjuncts in the achievement of BP goals.
