Abstract

Introduction: The investigation of psychometric properties of the short-form of selfmanagement ability scale in older people, including reliability, validity, confirmatory and exploratory factor analysis was the purpose of this study. Method: In this descriptivesurvey study, 283 older people (135 males and 148 females), were selected through available sampling in Tehran. The construct validity of management ability scale was investigated through exploratory factor analysis and main components method by using varimax orthogonal rotation. Reliability of the scale was calculated by test-retest method and ordinal alpha coefficient. Results: The exploratory factor analysis showed six factors (taking initiative, investing, self-efficacy, variety, multifunctionality and positive frame of mind). Test-retest reliability and internal consistency the ordinal alpha coefficients assumed good. Conclusion: According to the results of current research, the short-form of selfmanagement ability scale is a reliable instrument with appropriate psychometric properties to measure the rate of self-management ability in Iranian older people.

调查老年人自我管理能力简易量表的因素结构、信度和效度
前言:本研究的目的是调查老年人自我管理能力简易量表的心理测量特性,包括信度、效度、验证性和探索性因素分析。方法:在这项描述性调查研究中,在德黑兰通过现有抽样选择了283名老年人(男性135名,女性148名)。采用变量正交旋转法,通过探索性因子分析和主成分法对管理能力量表的编制效度进行了研究。采用重测法和序数α系数计算量表的信度。结果:探索性因子分析显示主动性、投资性、自我效能、多样性、多功能性和积极心态6个因子。重测信度和内部一致性的序数α系数假设良好。结论:根据目前的研究结果,简易自我管理能力量表是一种可靠的工具,具有适当的心理测量特性,可用于测量伊朗老年人的自我管理能力。
