Since this tool has been standardized in other countries, adapting it to the culture and context of Iran is necessary. This study aimed to determine the psychometric properties of the Persian version of the PROQOL questionnaire for nurses. The study population included nurses working in the educational and medical centers of Torbat Heydariyeh University of Medical Sciences. Three hundred nurses were selected using convenience sampling according to the inclusion criteria. Data were collected using a demographic questionnaire and the 30-item PROQOL questionnaire. Confirmatory factor analysis was performed using Lisrel version 8.8 to examine the factor structure, and internal reliability was assessed with SPSS version 20. Face and content validity were first confirmed using qualitative methods. Due to incomplete questionnaires, data from 267 participants were analyzed. Confirmatory factor analysis showed that after removing three items (2, 15, and 29), the model fit indices improved. Internal reliability was confirmed as Cronbach&rsquo;s alpha for all dimensions was greater than 0.7. The Persian version of the questionnaire, with 27 items, has acceptable construct validity and good internal reliability in the first and third dimensions.</span></p> Validity, Reliability, Professional Quality of Life Questionnaire 67 74 http://jrhms.thums.ac.ir/browse.php?a_code=A-10-200-1&slc_lang=en&sid=1 Maryam Tatari 10031947532846001652 10031947532846001652 Yes Department of Epidemiology and Biostatistics, School of Health, Torbat Heydariyeh University of Medical Sciences, Torbat Heydariyeh, Iran Somaye Barzanouni 10031947532846001653 10031947532846001653 No Vice Chancellery of Education and Research, Torbat Heydariyeh University of Medical Sciences, Torbat Heydariyeh, Iran.
