目的。本研究比较了针对个人采取运动的动机准备阶段量身定制的自助干预与标准自助运动促进干预的效果。干预措施在基线和1个月时实施；在基线和3个月时进行评估。11个工作场所参与工作健康研究试验。受试者。参与者（n = 1559）是参与工作场所的员工的子样本，单独随机分配到两种治疗条件中的一种。印刷的自助运动推广材料，要么(1)与个人采用运动的动机准备阶段相匹配（动机量身定制），要么(2)标准材料（标准）。运动动机准备阶段和7天体力活动回忆的测量。结果。在干预完成者（n = 903）中，卡方分析显示，与标准干预相比，接受动机量身定制干预的人在动机准备阶段明显更有可能表现出增加（37%对27%），而不太可能表现出没有变化（52%对58%）或回归（11%对15%）。多变量方差分析表明，动机准备阶段的变化与自我报告运动时间的变化显著相关。这是第一个前瞻性、随机、对照试验，证明了与标准的自助干预相比，短期动机量身定制的干预对锻炼的效果。这些发现似乎支持治疗方法，使干预措施适合个人的动机准备阶段的运动采用。
Purpose. This study compares the efficacy of a self-help intervention tailored to the individual's stage of motivational readiness for exercise adoption with a standard self-help exercise promotion intervention.Design. Interventions were delivered at baseline and 1 month; assessments were collected at baseline and 3 months.Setting, Eleven worksites participating in the Working Healthy Research Trial.Subjects. Participants (n = 1559) were a subsample of employees at participating worksites, individually randomized to one of two treatment conditions.Intervention. Printed self-help exercise promotion materials either (1) matched to the individual's stage of motivational readiness for exercise adoption (motivationally tailored), or (2) standard materials (standard).Measures. Measures of stage stage of motivational readiness for exercise and 7-Day Physical Activity Recall.Results. Among intervention completers (n = 903), chi-square analyses showed that, compared to the standard intervention, those receiving the motivationally tailored intervention were significantly more likely to show increases (37% vs. 27%) and less likely to show either no change (52% vs. 58%) or regression (11% vs. 15%) in stage of motivational readiness. Multivariate analyses of variance showed that changes in stage of motivational readiness were significantly associated with changes it self-reported time spent in exercise.Conclusions. This is the first prospective, randomized, controlled trial demonstrating the efficacy of a brief motivationally tailored intervention compared to a standard self-help intervention for exercise adoption. These findings appear to support treatment approaches that tailor interventions to the individual's stage of motivational readiness for exercise adoption.
