Changes in mood following exercise are well documented; however, one particular limitation of research examining mood changes associated with exercise is that studies have not controlled for a possible expectancy effect. Given the difficulty associated with utilising a placebo control group in exercise settings and that no current questionnaires are available to measure beliefs concerning mood improvements during and after exercise, the present studies aimed to develop a suitable instrument for assessing these beliefs. In the first of these studies, 220 regular runners were respondents in developing the new scale. A logical approach to test construction, as proposed by Hase and Goldberg in 1967, produced two scales of acceptable reliability: a five-item subscale to measure beliefs concerning mood improvements during running (Cronbach alpha=.77) and a two-item subscale to measure beliefs about mood improvements following running (Cronbach alpha=.86). A second study, which involved the administration of these scales to 50 regular runners after a 60-min. treadmill run, indicated there were moderate associations between scores on these measures and mood changes during and after the run.
运动后情绪的变化已有充分记录；然而，研究运动相关情绪变化的一个特别局限在于，研究并未控制可能存在的期望效应。鉴于在运动环境中使用安慰剂对照组存在困难，且目前没有可用的问卷来测量关于运动期间及之后情绪改善的信念，本研究旨在开发一种合适的工具来评估这些信念。在这些研究的第一项中，220名经常跑步者参与了新量表的编制。正如哈泽和戈德堡在1967年所提议的，一种合理的量表构建方法产生了两个可靠性可接受的量表：一个包含五个条目的子量表，用于测量跑步期间情绪改善的信念（克朗巴哈系数α = 0.77），以及一个包含两个条目的子量表，用于测量跑步后情绪改善的信念（克朗巴哈系数α = 0.86）。第二项研究让50名经常跑步者在进行60分钟跑步机跑步后使用这些量表，结果表明这些测量得分与跑步期间及之后的情绪变化之间存在中度关联。
