The study of psychometric properties of the Multidimensional Scale Perceived Social Support

Introduction: The aim of this study was to investigate the psychometric properties of the Persian version of the Multidimensional Scale of Perceived Social Support (MSPSS).Method: A total of 119 personnel of the Utilities Company of Khuzestan were selected using a random method of those who completed the MSPSS and a Mental Health Questionnaire. Data were analyzed with AMOS-16.Results: The results showed a high internal consistency for the whole scale and for three extracted factors. Item-total correlations were between 0.46 and 0.76, and all were significant. Divergent validity coefficients were significant for the whole scale and for the family and friends sub-scales with mental health, but the other sub-scales were not significant. In the exploratory factor analysis (Promax rotation), three factors were extracted: Family, friends, and significant others accounted for 70.48percent of the variance. Based on several goodness-of-fit indicators, a three-factor model for the MSPSS was supported in this personnel sample.Conclusion: The Persian version of the MSPSS can be used as a reliable and valid instrument in educational, clinical, and research settings and, in particular, in prevention and stress reduction.
