ABSTRACT
This study was undertaken to translate and validate the Rosenberg Self-Esteem Scale (RSES) for use among Malaysian adult asthma patients. A total of 152 adult asthma patients were enrolled from four respiratory clinics. The 10-item RSES was translated into Malaysian language by stepwise iterative translation procedure. After establishing the content and face validation of Malay version of RSES (RSES-M), internal consistency and test-retest reliability were assessed. The Cronbach’s α and Interclass Correlation Coefficient (ICC) values were 0.781 and 0.884. Kaiser-Mayer-Olkin (KMO) value (0.681) proved the sample adequacy and Barlett’s test of sphericity x2 (45) = 419.37, p < 0.001 indicated that correlations between items were sufficiently large for factor analysis. Moreo-ver, all values of output tables for items’ construct were within the specified ranges of the Rasch model. RSES-M is a reliable and valid scale that is conceptually and psychometrically equivalent to English version.
