The objective of this study was to investigate the validity and reliability of the Farsi version of the perceived benefits/barriers scale of physical activity in Iranian elderly.
Overall, 388 elderly subjects (60 yr and over) completed the demographic characteristics questionnaire, the Exercise Benefits/Barriers Scale (EBBS) and the Yale physical activity scale. Data were analyzed through of exploratory factor analysis, using Varimax rotation, Cronbach's alpha and Pearson correlation.
The matrix table of rotated elements of Farsi version of EBBS showed ten components, and 41 items predicted 61.83% of variance. 28 items in 5 components for benefits of, and 13 items in 5 components for barriers to physical activity were identified. Cronbach's alpha for internal consistency in the whole scale and its subscales was 0.83, 0.94 and 0.68. In addition, positive and significant correlation was found between overall benefits and their sub-scales as well as between overall barriers and their subscales. Moreover, there was significant and positive correlation between physical activity and the benefits (r=0.209, P=0.005) and significant negative correlation between physical activity and the barriers (r=-0.231, P=0.001).
The results showed acceptable reliability and validity of the Farsi version of Exercise Benefits/Barriers Scale among Iranian elderly.
本研究的目的是调查伊朗老年人身体活动感知益处/障碍量表波斯语版本的有效性和可靠性。
总共388名老年受试者（60岁及以上）完成了人口统计学特征问卷、运动益处/障碍量表（EBBS）和耶鲁身体活动量表。通过探索性因素分析，使用方差最大化旋转、克朗巴赫α系数和皮尔逊相关性对数据进行分析。
EBBS波斯语版本旋转元素的矩阵表显示有十个成分，41个项目解释了61.83%的方差。确定了身体活动益处的5个成分中的28个项目以及身体活动障碍的5个成分中的13个项目。整个量表及其子量表内部一致性的克朗巴赫α系数分别为0.83、0.94和0.68。此外，总体益处与其子量表之间以及总体障碍与其子量表之间存在显著正相关。而且，身体活动与益处之间存在显著正相关（r = 0.209，P = 0.005），身体活动与障碍之间存在显著负相关（r = -0.231，P = 0.001）。
结果表明运动益处/障碍量表波斯语版本在伊朗老年人中具有可接受的可靠性和有效性。
