The purpose of this study is to evaluate the effect of a preintervention physical activity preparatory course on physical activity, and social, cognitive, and transtheoretical constructs. The sample included 82 low-income, multiethnic women (75% Latina) who completed an 8-week course designed to prepare them to become more active prior to randomization into a 10-month physical activity intervention. Participants completed precourse and postcourse measures. Paired-comparison t tests showed increases in knowledge, perceived social support for exercise, minutes of walking per week, and total cognitive and behavioral processes following the preparatory course. Perceived barriers and self-efficacy for exercise did not change from precourse to postcourse. Preintervention preparatory courses may be an effective way to increase social and cognitive constructs associated with physical activity behavior, potentially yielding a greater effect from subsequent interventions.
本研究的目的是评估干预前体育活动预备课程对体育活动以及社会、认知和跨理论结构的影响。样本包括82名低收入、多民族女性（75%为拉丁裔），她们完成了一个为期8周的课程，该课程旨在让她们在被随机分配到为期10个月的体育活动干预之前变得更加活跃。参与者完成了课程前和课程后的测量。配对比较t检验显示，预备课程后，知识、对运动的感知社会支持、每周步行分钟数以及总的认知和行为过程均有所增加。运动的感知障碍和自我效能从课程前到课程后没有变化。干预前预备课程可能是增加与体育活动行为相关的社会和认知结构的有效方式，可能会使后续干预产生更大的效果。
