analyze and assess the psychometric properties of the subscales in the Spanish version of the Exercise Benefits/Barriers Scale in an elderly population in the Northeast of Mexico.
methodological study. The sample consisted of 329 elderly associated with one of the five public centers for senior citizens in the metropolitan area of Northeast Mexico. The psychometric properties included the assessment of the Cronbach's alpha coefficient, the Kaiser Meyer Olkin coefficient, the inter-item correlation, exploratory and confirmatory factor analysis.
in the principal components analysis, two components were identified based on the 43 items in the scale. The item-total correlation coefficient of the exercise benefits subscale was good. Nevertheless, the coefficient for the exercise barriers subscale revealed inconsistencies. The reliability and validity were acceptable. The confirmatory factor analysis revealed that the elimination of items improved the goodness of fit of the baseline scale, without affecting its validity or reliability.
the Exercise Benefits/Barriers subscale presented satisfactory psychometric properties for the Mexican context. A 15-item short version is presented with factorial structure, validity and reliability similar to the complete scale.
分析并评估墨西哥东北部老年人群中西班牙语版《运动益处/障碍量表》各分量表的心理测量特性。
方法学研究。样本包括与墨西哥东北部大都市地区五个公共老年中心之一相关联的329名老年人。心理测量特性包括对克朗巴赫α系数、凯泽-迈耶-奥尔金系数、项目间相关性、探索性和验证性因素分析的评估。
在主成分分析中，根据量表中的43个项目确定了两个成分。运动益处分量表的项目-总分相关系数良好。然而，运动障碍分量表的系数显示出不一致性。信度和效度是可接受的。验证性因素分析表明，项目的剔除提高了基线量表的拟合优度，而不影响其效度或信度。
《运动益处/障碍量表》分量表在墨西哥背景下呈现出令人满意的心理测量特性。给出了一个15项的简短版本，其因子结构、效度和信度与完整量表相似。
