通过测量期望，对运动心理反应中安慰剂和反安慰剂效应的理解得到改善。尽管有几种有效的期望测量方法，但我们主张使用将运动引起的变化的积极和消极期望都考虑在内的量表。横断面调查。一份调查问卷用于收集关于运动如何影响14种与心理健康相关的不同结果的积极和消极预期的信息（n = 966）。大多数样本（50%）报告了对运动引起的变化的积极期望的结果包括：心理健康（75.3%）、抑郁（74.3%）、放松（74.2%）、睡眠质量（73.3%）、压力（72.2%）、焦虑（69.8%）、精力（67.1%）和注意力（60.2%）。大多数样本（bbb50 %）报告运动引起的变化的负面预期结果是肌肉疼痛（66.3%），疲劳（57.3%）和关节疼痛（50.7%）。在所有14个结果中，对运动引起的变化持负面预期的参与者比例从5.9%到66.3%不等。阐明安慰剂和反安慰剂效应的潜在存在可以提高对运动对心理健康影响的方向和程度的变异性的理解。虽然只有3种结果大多数参与者报告了负面预期，但我们发现，在所有14种结果中，负面预期都不同程度地存在。因此，对于希望在运动心理反应研究中描述安慰剂和反安慰剂效应潜在存在的研究人员，我们建议使用同等考虑积极和消极预期的测量方法。
The understanding of placebo and nocebo effects in psychological responses to exercise is improved by measuring expectations. Despite availability of several validated expectancy measures, we argue for using scales that take both positive and negative expectations for exercise-induced changes into account. Cross-sectional survey. A questionnaire was used to collect information on positive and negative expectations pertaining to how exercise would affect 14 different outcomes related to psychological health (n = 966). Outcomes for which a majority of the sample (>50%) reported positive expectations for exercise-induced changes included: psychological well-being (75.3%), depression (74.3%), relaxation (74.2%), sleep quality (73.3%), stress (72.2%), anxiety (69.8%), energy (67.1%), and attention (60.2%). Outcomes for which a majority of the sample (>50%) reported a negative expectation for exercise-induced changes were muscle pain (66.3%), fatigue (57.3%), and joint pain (50.7%). Across all 14 outcomes, the percentage of participants with negative expectations for exercise-induced changes ranged from 5.9 to 66.3%. Elucidating the potential presence of placebo and nocebo effects can improve the understanding of variability in the direction and magnitude of exercise-related effects on psychological health. Although there were only 3 outcomes for which the majority of participants reported negative expectations, we found that negative expectations were present to some degree for all 14 outcomes. Thus, for researchers who wish to characterize the potential presence of placebo and nocebo effects in studies of psychological responses to exercise, we recommend using measures that give equal consideration to positive and negative expectations.
