The purpose of the present study was to examine the reliability, factorial validity and measurement invariance (across gender,
age and physical activity participation) of a Portuguese version of the Rosenberg Self-Esteem Scale (RSES). The sample consisted
of 1,763 Portuguese youngsters (731 male and 1,032 female) with ages between 15 and 20 years. Reliability estimate for the
one-factor solution was .845, although some proposed RSES’s underlying dimensions were lower than .70. Confirmatory factor
analysis revealed that the best-fitting model was a single self-esteem factor, plus simultaneous correlated uniqueness for
positively and negatively worded items. Multigroup analysis supported measurement invariance across age and physical activity
participation, and partial metric invariance across gender, as three items failed to show metric equivalence. These results
provide evidence that RSES has excellent psychometric properties and it is a valid self-esteem measure to be used among Portuguese
youngsters. 相似文献
