title: A randomized trial using motivational interviewing for maintenance of blood pressure improvements in a community-engaged lifestyle intervention: HUB city steps.
abstract: Little is known about the effective dose of motivational interviewing for maintaining intervention-induced health outcome improvements. The purpose of this study was to compare effects of two doses of motivational interviewing for maintaining blood pressure improvements in a community-engaged lifestyle intervention conducted with African-Americans. Participants were tracked through a 12-month maintenance phase following a 6-month intervention targeting physical activity and diet. For the maintenance phase, participants were randomized to receive a low (4) or high (10) dose of motivational interviewing delivered via telephone by trained research staff. Generalized linear models were used to test for group differences in blood pressure. Blood pressure significantly increased during the maintenance phase. No differences were apparent between randomized groups. Results suggest that 10 or fewer motivational interviewing calls over a 12-month period may be insufficient to maintain post-intervention improvements in blood pressure. Further research is needed to determine optimal strategies for maintaining changes.
