Enjoyment has been implicated as a determinant of physical activity among youth, but advances in understanding its importance have been limited by the use of measures that were not adequately validated. The present study examined: (1) the factorial validity of the Physical Activity Enjoyment Scale (PACES), and (2) the construct validity of PACES scores.
Adolescent girls (N=1797), who were randomly assigned to calibration (n=899) and cross-validation (n=898) samples, completed the PACES and measures of factors influencing enjoyment of physical education, physical activity, and sport involvement. The factorial validity of the PACES and the measure of factors influencing enjoyment of physical education was tested using exploratory and confirmatory factor analysis. The hypothesized relationships among the measures were tested using structural equation modeling.
Unidimensional models fit the PACES and the measure of factors influencing enjoyment of physical education in the calibration and cross-validation samples. The hypothesized relationships between the PACES and the measures of factors influencing enjoyment of physical education, physical activity, and sport involvement were supported in the entire sample, were similar in African-American and Caucasian girls, and were independent of physical fitness.
Evidence of factorial validity and convergent evidence for construct validity indicate that the PACES is a valid measure of physical activity enjoyment among adolescent girls, suitable for use as a mediator variable in interventions designed to increase physical activity.
愉悦感被认为是青少年身体活动的一个决定因素,但对其重要性的理解进展一直受到使用未充分验证的测量方法的限制。本研究考察了:(1)身体活动愉悦感量表(PACES)的因子效度,以及(2)PACES得分的结构效度。
将青少年女孩(N = 1797)随机分配到校准样本(n = 899)和交叉验证样本(n = 898)中,她们完成了PACES以及影响体育教育、身体活动和运动参与愉悦感的因素的测量。使用探索性和验证性因子分析来检验PACES的因子效度以及影响体育教育愉悦感的因素的测量。使用结构方程模型来检验测量之间的假设关系。
单维模型适用于校准样本和交叉验证样本中的PACES以及影响体育教育愉悦感的因素的测量。PACES与影响体育教育、身体活动和运动参与愉悦感的因素的测量之间的假设关系在整个样本中得到支持,在非裔美国女孩和白人女孩中相似,并且与身体素质无关。
因子效度的证据和结构效度的收敛证据表明,PACES是青少年女孩身体活动愉悦感的有效测量方法,适用于作为旨在增加身体活动的干预措施中的中介变量。
