We aimed at verifying the psychometric properties of the Life Satisfaction Index-A (LSIA), used to evaluate life satisfaction and well-being, among older Iranians.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n The forward\u2013backward procedure was used for translating the English version of the LSIA into Persian. Thereafter, face and content validity were done by 15 specialists. Confirmatory factor analysis (CFA) was done for construct validity. Reliability was evaluated by using the Cronbach\u2019s alpha method. Statistical analysis was performed using Mplus 7.4. p<0.05 was considered statistically significant.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n In the face validity, more than 90% of all questions had an impact score above 1.5, content validity ratio (CVR) >0.6, and content validity index (CVI) >0.8. CFA showed that the first-level factors \u2018resolution and fortitude\u2019, \u2018Zest\u2019 and \u2018congruence between desired and achieved goals in life\u2019 explain the first factor of the second level which is \u2018the perception of reality\u2019, and the first level factors \u2018positive self-concept\u2019 and \u2018mood tone\u2019 explain the second factor of the second level which is \u2018mental perception\u2019. The proposed structural model showed acceptable to the data and Cronbach\u2019s alpha for the LSIA\u2019s dimensions ranged between 0.89 and 0.95.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The findings suggest that the LSIA appears to be an appropriate instrument for older adults in Iran, but it needs further validation to explore different sub-cultural aspects in the older Iranian population.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/nmji_988_2022","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T07:20:28Z","timestamp":1763968828000},"page":"326-331","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Psychometric properties of the Life Satisfaction Index version A (LSIA) among older adults in Iran"],"prefix":"10.25259","volume":"38","author":[{"given":"MARYAM","family":"CHEHREHGOSHA","sequence":"first","affiliation":[{"name":"Department of Surgical Technology, Golestan University of Medical Sciences, Golestan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"NASER","family":"ESKANDARI","sequence":"additional","affiliation":[{"name":"Department of Psychology, Azad Islamic University, Golestan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BAGHER","family":"PAHLAVANZADEH","sequence":"additional","affiliation":[{"name":"School of Health, Research Center for Environmental Contaminants (RCEC), Abadan University of Medical Sciences, Abadan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MOHAMMAD TAGHI","family":"BADELEH SHAMUSHAKI","sequence":"additional","affiliation":[{"name":"Golestan University of Medical Sciences, Golestan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2025,11,24]]},"reference":[{"key":"10.25259\/NMJI_988_2022\/ref-1","doi-asserted-by":"publisher","first-page":"102","DOI":"10.3897\/popecon.3.e47192","article-title":"Analysis of life satisfaction of the elderly population on the example of Sweden, Austria and Germany","volume":"3","author":"Kutubaeva","year":"2019","journal-title":"Popul Econ"},{"key":"10.25259\/NMJI_988_2022\/ref-2","doi-asserted-by":"publisher","first-page":"121","DOI":"10.1007\/s10823-017-9340-6","article-title":"The Persian Version of the \u201cLife Satisfaction Scale\u201d: Construct Validity and Test-Re-Test Reliability among Iranian Older Adults","volume":"33","author":"Moghadam","year":"2018","journal-title":"J Cross Cult Gerontol"},{"key":"10.25259\/NMJI_988_2022\/ref-3","doi-asserted-by":"publisher","first-page":"475","DOI":"10.2147\/JPR.S234565","article-title":"Factors associated with life satisfaction in older adults with chronic pain (PainS65+)","volume":"13","author":"Dong","year":"2020","journal-title":"J Pain Res"},{"key":"10.25259\/NMJI_988_2022\/ref-4","doi-asserted-by":"publisher","first-page":"215824402097982","DOI":"10.1177\/2158244020979823","article-title":"The psychometric properties of the Turkish version of the Riverside Life Satisfaction Scale-Adult Form","volume":"10","author":"Al\u00fdc\u00fd","year":"2020","journal-title":"SAGE Open"},{"key":"10.25259\/NMJI_988_2022\/ref-5","doi-asserted-by":"publisher","first-page":"7","DOI":"10.1080\/14330237.2019.1569301","article-title":"Predictors of life satisfaction among multicultural African families in South Korea","volume":"29","author":"Choi","year":"2019","journal-title":"J Psychol Afr"},{"key":"10.25259\/NMJI_988_2022\/ref-6","doi-asserted-by":"publisher","first-page":"1027","DOI":"10.1080\/1369183X.2018.1438252","article-title":"Immigrant life satisfaction in Europe: The role of social and symbolic boundaries","volume":"45","author":"Heizmann","year":"2019","journal-title":"J Ethn Migr Stud"},{"key":"10.25259\/NMJI_988_2022\/ref-7","doi-asserted-by":"publisher","first-page":"191","DOI":"10.1080\/13607860802342227","article-title":"What matters, and what matters most, for change in life satisfaction in the oldest-old?
