Abstract

Aim: This study aimed to translate and adapt the 10 items Rosenberg Self-esteem scale into the Nepali language and to examine the validity of the Nepali version through exploratory factor analysis, internal consistency, and test-retest reliability in an adult population. Method: World Health Organization guideline was followed to translate and adapt the Nepali version of the Rosenberg Self-esteem scale. 330 accompanying adults of patients visiting psychiatry outpatient of Tribhuvan University Teaching Hospital, Nepal completed the Nepali version of the questionnaire. Psychometric properties of the scale were determined by measuring construct validity through exploratory factor analysis, estimating internal consistency, and assessing test-retest reliability. Result: Polychoric correlation matrix demonstrated that 37% of item pairs had a correlation coefficient of >0.3. Communalities of most items were >0.200. Factor loading of all items was >0.30 except for item 8. Principal axis factoring and parallel analysis established the two-factor structure of the scale. Cronbach's alpha after deletion of item 8 was 0.711. Item level test-retest reliability showed that 70% of items had moderate reliability. Conclusion: Nepali Rosenberg self-esteem scale without item 8 is a psychometrically sound tool to assess self-esteem in the adult Nepali population.
