This study aimed to investigate the factor structure, validity, and reliability of the Locus-of-Hope Scale in Iranian students. The research method was descriptive-correlational. The statistical population of this study included all students of Islamic Azad University, Roodehen, Iran. The sample size was 307 people who were selected through cluster random sampling. The Locus-of-Hope Scale (LHS) was used to collect data. Cronbach&rsquo;s alpha was used to assess the reliability of the questionnaire. Also, the reliability coefficients for the subscales of the questionnaire were obtained between 0.71 and 0.87. Confirmatory factor analysis (CFA) was used to evaluate the validity of the questionnaire. CFA revealed a four-factor structure, and four subscales (i.e., internal, external-family, external-peers, and external-spiritual) were confirmed. Also, all indicators of model fitness were obtained at an appropriate level. As a result, based on the present study&rsquo;s findings, the LHS can be used for research and treatment purposes related to hope among Iranian students.</span></span></span></span></span></div> Life expectancy questionnaire, Exploratory factor analysis, Confirmatory factor analysis 204 212 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-320-1&slc_lang=en&sid=1 Mehdi Kelantari مهدی کلانتری 10031947532846006009 10031947532846006009 Yes Department of Educational Management, Rodehen Branch, Islamic Azad University, Rodehen, Iran استادیار گروه مدیریت آموزش عالی، واحد رودهن، دانشگاه آزاد اسلامی واحد رودهن، رودهن، ایران Hoda Haddadi هدی حدادی haddadi_hoda@yahoo.com 10031947532846006010 10031947532846006010 No Islamic Azad University, Roodehen Branch, Roodehen, Iran دانشگاه ازاد اسلامی واحد رودهن، رودهن، ایران
