对于维持干预引起的健康结果改善的动机性访谈的有效剂量知之甚少。本研究的目的是比较在对非裔美国人进行的社区参与生活方式干预中，两种剂量的动机访谈对维持血压改善的效果。在针对身体活动和饮食进行为期 6 个月的干预后，对参与者进行了为期 12 个月的维持阶段的跟踪。在维持阶段，参与者被随机接受由训练有素的研究人员通过电话进行的低剂量 (4) 或高剂量 (10) 动机访谈。使用广义线性模型来测试血压的组间差异。维持阶段血压显着升高。随机组之间没有明显差异。结果表明，12 个月内 10 次或更少的动机性访谈电话可能不足以维持干预后血压的改善。需要进一步的研究来确定维持变化的最佳策略。
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.
