Studies have shown that expectations about exercise outcomes are associated with exercise behavior. Outcome expectations can be assessed by self-report questionnaires, but a new method-the expectancy accessibility task-may convey unique information about outcome expectations that is less subject to respondent biases. This method involves measuring the reaction time to endorse or reject an outcome We examined the relationship of self-reported outcome expectations and expectancy accessibility tasks in a pilot study of sedentary endometrial cancer survivors (N = 20). After measuring outcome expectations and expectancy accessibility, participants were given an exercise program and asked to monitor exercise for 7 days using diaries and accelerometers. Analyses revealed no relationship between outcome expectation scores and exercise, but shorter response times to endorse positive exercise outcomes was related to more exercise in the next week (p = .02).
研究表明，对运动结果的期望与运动行为有关。可以通过自我报告问卷来评估结果期望，但一种新的方法——期望可及性任务——可能会提供关于结果期望的独特信息，这些信息较少受到被试偏见的影响。这种方法涉及到衡量对结果的赞成或反对的反应时间。我们在一项久坐的子宫内膜癌幸存者的初步研究中考察了自我报告的结果期望和期望可及性任务之间的关系（N = 20）。在测量了结果期望和期望可及性之后，参与者接受了一个锻炼计划，并被要求使用日记和加速度计来监测 7 天的锻炼情况。分析显示，结果期望得分与运动之间没有关系，但对积极运动结果的反应时间越短，下一周的运动就越多（p =.02）。
