This study assessed the effects of frequency of prompting (phone calls once a week versus once every 3 weeks) and structure of prompting (high versus low structure) in 135 participants (132 women and 3 men) in a walking program designed to meet the American College of Sports Medicine's cardiovascular exercise goals. Survival analysis using 6 months of data points and using the criteria of walking at least 20 min a day for at least 3 times per week indicated an effect for more frequent versus less frequent prompting (46% and 13%) but not for high- versus low-structure prompting (30% and 31%). The results suggested the efficacy of frequent prompting delivered in inexpensive ways as a means to increase exercise adherence and the further parametric study of other basic behavior change strategies.
本研究评估了提示频率（每周一次电话与每三周一次电话）和提示结构（高结构与低结构）对135名参与者（132名女性和3名男性）的影响，这些参与者参加了一个旨在实现美国运动医学学会心血管运动目标的步行计划。使用6个月的数据点进行生存分析，并以每天至少步行20分钟、每周至少3次为标准，结果表明提示频率较高与较低相比有效果（分别为46%和13%），但高结构与低结构提示相比没有效果（分别为30%和31%）。结果表明，以低成本方式进行频繁提示作为提高运动依从性的一种手段是有效的，并且还需对其他基本行为改变策略进行进一步的参数研究。
