Family Interventions in the Spirit of Motivational Interviewing (FITSMI)

The Primary Objectives are to (1) Using a stroke risk score developed for research in American Indian (AI) populations, estimate the effectiveness of the Family Intervention in the Spirit of Motivational Interviewing (FITSMI) in adults ages 45 and older by comparing the change in stroke risk scores from baseline to 1-year follow-up in households randomized to the intervention and control conditions. (2) Quantify the impact of the FITSMI among AI adolescents and adults ages 11 to 44 by comparing changes in blood pressure and smoking behavior from baseline to 1-year follow-up in intervention and control households. While the Secondary Objectives are (1) Evaluate the impact of the FITSMI on individual components of the stroke risk score, including blood pressure, blood lipids, smoking, microalbuminuria, and prevention of diabetes and cardiovascular disease, and (2) If the FITSMI is effective, quantify the population impact in terms of preventable strokes over 10 years.
