This study addressed the influence of pedometers and a pretest on walking intentions and behaviour. Using a Solomon four-group design, 63 female university students were randomly assigned to one of four conditions: pedometer and pretest (n = 16), pedometer and no pretest (n = 16), no pedometer and pretest (n = 15), no pedometer and no pretest (n = 16). The pretest conditions included questions on walking, intentions to walk 12,500 steps per day, and self-efficacy for walking 12,500 steps per day. In the pedometer conditions a Yamax Digi-Walker SW-650 pedometer was worn for one week. All participants completed posttest questions. While significant pretest x pedometer interactions would have indicated the presence of pretest sensitisation, no such interactions were observed for either intention or self-reported walking. Wearing pedometers reduced intentions for future walking and coping self-efficacy. However, after controlling for pretest self-reported walking, pedometer use resulted in more self-reported walking. We conclude that wearing a pedometer increased self-reported walking behaviour but that a pretest did not differentially influence walking intentions, behaviour, or self-efficacy.
本研究探讨了计步器和预测试对步行意愿和行为的影响。采用所罗门四组设计，将 63 名女性大学生随机分配到以下四个条件之一：计步器和预测试（n=16）、计步器和无预测试（n=16）、无计步器和预测试（n=15）、无计步器和无预测试（n=16）。预测试条件包括有关步行、每天走 12500 步的意愿和每天走 12500 步的自我效能感的问题。在计步器条件下，佩戴 Yamax Digi-Walker SW-650 计步器一周。所有参与者都完成了后测问题。虽然预测试 x 计步器的显著相互作用表明存在预测试敏感化，但在意图或自我报告的步行方面没有观察到这种相互作用。佩戴计步器会降低未来步行的意愿和应对自我效能感。然而，在控制预测试自我报告的步行后，计步器的使用导致更多的自我报告的步行。我们得出结论，佩戴计步器增加了自我报告的步行行为，但预测试并没有对步行意愿、行为或自我效能感产生不同的影响。
