Introduction: This study was conducted to examine the psychometric properties of the Persian short version of the Social and Emotional Loneliness Scale for Adults for its conformity in Iran.Method: In a cross-sectional study, 329 (187 female, 142 male) students from the University of Shiraz were assessed using the short form of the Social and Emotional Loneliness Scale (SELSA-S) and the Satisfaction With Life Scale (SWLS) and Multidimensional Scale of Perceived Social Support (MSPSS). Data were analyzed using correlation coefficients, factor analysis and t-tests.Results: After the translation of the SELSA-S scale and the cultural conformity of its agents, the factor analysis of the convergent coefficients to MSPSS and SWLS methods were used to determine its validity. The results of the factor analysis revealed three factors in the SELSA-S scale that were described as a loneliness feeling in romance, in society, and in family. The results of the other convergent scales showed confirmatory validity and pertinent exploration of the questionnaire. To determine the reliability, Kronbach’s alpha was used, and it was 0.92, 0.84, and 0.78 for romantic, social, and family aspects, respectively.Conclusion: The findings of this study show that the Persian version of the SELSA-S is reliable and valid for Iranian students and is able to measure loneliness in romantic, family, and social aspects efficiently.
