Introduction: The investigation of psychometric properties of the short-form of self-management ability scale in older people, including reliability, validity, confirmatory and exploratory factor analysis was the purpose of this study.
Method: In this descriptive- survey 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 self-management ability scale is a reliable instrument with appropriate psychometric properties to measure the rate of self-management ability in Iranian older people.
