The Translation and Psychometric Evaluation of the Persian Version of Brief Multidimensional Life Satisfaction Scale for Iranian Patients with Cancer

Abstract

Background: Due to the growing prevalence of cancer globally, the disease is considered one of the most important sources of stress, disability, and reduced life satisfaction. Although life satisfaction is supposed to be a relatively stable psychological construct, it may change in response to life events. Life-satisfaction is the assessment of the quality of life according to one’s chosen criteria. Objectives: The purpose of this research is the psychometric evaluation of the Persian version of “Brief Multidimensional Life Satisfaction Scale” (BMLSS) in Iranian patients with cancer. Methods: The present study was a methodological research, during which the BMLSS was translated and the Farsi version was validated for patients with cancer. Results: The fit indices of confirmatory factor analysis confirmed the dual dimension of the BMLSS. Regarding the convergent validity of the BMLSS, the total score of the instrument had a positive and significant relationship with age and the sense of religiosity. Cronbach's alpha and Intraclass Correlation were calculated. Conclusions: The findings indicated that this Persian version has good validity and reliability and can be used as a comprehensive instrument in Iran.
