Enjoyment is an important construct for understanding physical activity participation, and it has not been examined in adults with functional limitations. This secondary analysis reported the reliability and validity of the Physical Activity Enjoyment Scale (PACES) in a convenience sample of 40 adults with functional limitations. The participants completed the PACES, Center for Epidemiological Studies Depression Scale (CES-D), and the Late Life Function and Disability Instrument (LLFDI) prior to beginning a 12-week feasibility dance intervention study. Results indicated reliability as Cronbach's alpha was .95 and mean inter-item correlation was .52. To further support reliability, homogeneity of the instrument was evaluated using item-to-total scale correlations. Homogeneity was supported as all items had corrected item-to-total correlations greater than .30. For validity, the PACES was significantly related to only the Physical Function component of the LLFDI (r = .38, p = .02), but not the CES-D. Exploratory factor analysis revealed a 3-factor structure that accounted for 73.76% of the variance. This feasibility intervention dance study represented the first attempt to examine the psychometric properties of the PACES in adults with functional limitations. The findings demonstrate support for the scale's reliability and validity among adults with functional limitations. Results are informative as further psychometric testing of the PACES is recommended using randomized clinical trials with larger sample sizes. Enjoyment for physical activity is an important construct for understanding physical activity participation in adults with functional limitations.
享受是理解身体活动参与情况的一个重要概念，而在有功能限制的成年人中尚未对此进行研究。这项二次分析报告了身体活动享受量表（PACES）在40名有功能限制的成年人便利样本中的信度和效度。参与者在开始一项为期12周的可行性舞蹈干预研究之前，完成了PACES、流行病学研究中心抑郁量表（CES-D）和晚年功能与残疾量表（LLFDI）。结果表明其信度，克朗巴哈系数α为0.95，平均项目间相关性为0.52。为进一步支持信度，使用项目与总量表相关性评估了该量表的同质性。所有项目的校正项目与总量表相关性均大于0.30，支持了同质性。在效度方面，PACES仅与LLFDI的身体功能部分显著相关（r = 0.38，p = 0.02），但与CES-D无关。探索性因素分析揭示了一个占方差73.76%的三因素结构。这项可行性干预舞蹈研究是首次尝试在有功能限制的成年人中检验PACES的心理测量特性。研究结果表明该量表在有功能限制的成年人中具有信度和效度。由于建议使用更大样本量的随机临床试验对PACES进行进一步的心理测量测试，因此这些结果具有参考价值。身体活动的享受是理解有功能限制的成年人身体活动参与情况的一个重要概念。
