ObjectivesThis study aimed at developing and determining psychometric properties of Active Aging Measurement Instrument (AAIM) as per the Iranian aging society. Methods & Materials This study was performed in two phases by applying the steps identified by Ingersoll-Dayton in 2015-2016. In the first phase, according to prior studies, a preliminary AAMI was developed through three steps. In the second phase through two steps, the psychometric properties of the AAMI were examined. A total of 350 older adults belonging to health-related educational centers in Tehran municipality were included in the psychometrics study using the three-phase cluster sampling method. Statistical tests such as item analysis, exploratory factor analysis, Cronbach's α coefficient, and Pearson correlation coefficient were performed by using SPSS 16. Results The finding of the first phase was a preliminary 6-item measurement instrument with 5 point responses (none to very much). In the second phase, the result of examining the face and content validity was elimination of 6 items, which led to a 55-item AAMI. The result of psychometric tests after item analysis and factor analysis was the final 40-item AAMI consisting of six factors: 1. social-institutional participation; 2. active mind maintenance; 3. social contacts; 4. agent attitude; 5. productive engagement; and 6. physical-functional activity which explained 56% of the total variance. Reliability of AAMI based on examining Cronbach's α coefficient was 0.88, and also its test-retest reliability was 0.95 (P<0.01). Conclusion The 40-item AAMI consisting of six factors in the present study not only was shown to be reliable, valid and appropriate for Iranian older adults but was also confirmed to have both subjective and objective dimensions.

Objectivesollowing the paradigm shift in the conception of aging experience, i.e. from the concept of "being alive" in the twentieth century to "ensuring the qual-F ity of life of elderly people" in the twenty-first century, active aging as a positive approach to aging has drawn the attention of policymakers and gerontologists [1].Understanding of active aging, which is influenced by the culture and conditions of each community, has been largely based on Western studies, not applicable to the culturally-diverse communities in Asian coun- tries [3]. Therefore, due to inappropriate measures of active aging in Iran, the present study aimed to design and determine the psychometric characteristics of active aging measures according to the cultural criteria of the Iranian aging society.
Methods & MaterialsThe present study was a methodological research and is a part of a larger study entitled "Understanding active aging and constructing its measure" carried out by a combined research method in two stages using the steps proposed by Ingramsal-Dayton [4]. In the first step of the first stage, the study was based on the grounded theory of qualitative research aimed at achieving the native theoretical model of active aging [5]. The data were sa...
