The measurement of physical activity habits is especially important in the evaluation of the consequences of chronic diseases. The study tries was to validate to the context Spanish the scale Self-Report Habit Index (SRHI) of 12 items for to measure the habit strength.
The psychometric properties of SRHI were analyzed realizing a analysis statistical of the items, an factorial analysis and an estimation of the reliability coefficient via Cronbach alpha. A sample of 222 university students of first year was used. The majority of they has practiced some type of sport during his school stage. To assess the adequacy of sampling and possible sphericity of data obtained, both Kaiser-Meyer-Olkin (KMO) tests were performed (which resulted in 0.953) and Bartlett (which resulted in p=.000).
The Cronbach alpha coefficient is 0.96. The results of a factor mining analysis (unrotated, orthogonal) point to a grouping of the 12 items into a single factor with eigenvalue of 8.342 and a percentage of total variance of 69.52%.
Results show that the scale is valid and reliable to measure physical activity habits A clear similarity of the psychometric properties of the Spanish version of the original version SRHI is shown.
身体活动习惯的测量在慢性病后果评估中尤为重要。本研究旨在将用于测量习惯强度的12项自陈习惯指数(SRHI)量表在西班牙语环境中进行验证。
通过对项目进行统计分析、因子分析以及使用克朗巴哈α系数估计信度系数,来分析SRHI的心理测量特性。使用了222名大学一年级学生作为样本。他们中的大多数人在中学阶段都进行过某种类型的体育运动。为评估抽样的充分性和所获数据的可能球形度,进行了凯泽-迈耶-奥尔金(KMO)检验(结果为0.953)和巴特利特检验(结果为p = 0.000)。
克朗巴哈α系数为0.96。因子提取分析(未旋转、正交)结果表明,12个项目可归为一个单一因子,特征值为8.342,总方差百分比为69.52%。
结果表明该量表在测量身体活动习惯方面有效且可靠。西班牙语版SRHI与原版在心理测量特性上显示出明显相似性。
