To test the efficacy in promoting brisk walking of two theory-based interventions that incorporate implementation intentions and text message (Short Message Service; SMS) reminders directed at one's walking-related plans or goals.
Participants (N = 149) were randomized to one of three conditions (implementation intention + SMS plan reminder, implementation intention + SMS goal reminder, control) before completing measures at baseline and follow-up 4 weeks later. At follow-up, the experimental groups were given a surprise recall task concerning their plans. All participants completed an equivalent goal recall task.
Validated self-report measures of physical activity and measures of implementation intention and goal recall, weight, and waist-to-hip ratio.
Both intervention groups increased their brisk walking relative to the control group, without reducing other physical activity. The goal reminder group lost the most weight. The SMS plan reminder group recalled more of their plans than the SMS goal reminder group, but the latter were more successful in goal recall.
Both interventions can promote brisk walking in sedentary populations. Text messages aid the recall of, and could enhance interventions that target, implementation intentions and goals.
测试两种基于理论的干预措施在促进轻快步行方面的效果，这两种干预措施结合了实施意向和针对个人步行相关计划或目标的短信（短消息服务；SMS）提醒。
参与者（N=149）在基线和 4 周后的随访中完成测量之前，被随机分配到三种条件之一（实施意向+SMS 计划提醒、实施意向+SMS 目标提醒、对照组）。在随访时，实验组接受了一项关于他们计划的惊喜回忆任务。所有参与者都完成了等效的目标回忆任务。
经过验证的体力活动自我报告测量指标，以及实施意向和目标回忆、体重和腰臀比的测量指标。
与对照组相比，两个干预组都增加了轻快步行的量，而没有减少其他体力活动。目标提醒组体重减轻最多。短信计划提醒组比短信目标提醒组回忆起更多的计划，但后者在目标回忆方面更成功。
两种干预措施都可以促进久坐人群的轻快步行。短信有助于回忆，并可以增强针对实施意向和目标的干预措施。
