This paper examines the appropriateness for Nepalese students of the Self Description Questionnaire-1 (SDQ-1; Marsh, 1988) and the Shavelson model of self-concept on which it is based. The results of an administration of the SDQ-1 to 404 Nepalese 11-12 year olds are reported. The item-scale correlations and reliability coefficients obtained were encouraging. Factor analysis generally supported both the specific facets of the SDQ-1 and the existence of an underlying general self-concept factor. The pattern of the relationships between self-concept and school grades generally was also in accord with the validity of the SDQ-1 for Nepalese subjects. These results are then considered in relation to other evidence of the cross-cultural validity of both the SDQ-1 and the Shavelson model of the self. Tentative comparisons of the Nepalese means to those of previously reported Australian and Filipino children of the same age indicated that there was a tendency for the Australians to have relatively higher Non-Academic self-esteem than the other nationalities.
