Aspects of the construct validity of a preliminary self-concept questionnaire
The aim of the study was to assess the construct validity of a Preliminary Self-concept Questionnaire and an Afrikaans version of the Selt-description Questionnaire of Marsh, Smith, and Barnes. Questionnaires were administered to 57 boys and 57 girls in Grades 5 and 7. Their self-concepts were rated by their teachers on a teacher's rating scale, based on the four subscales of the Preliminary Self-concept Questionnaire. Correlations among the total scores of the three self-concept measures were calculated, as well as correlations among corresponding subscale scores. These values supported the construct validity of the Preliminary Self-concept Questionnaire and the convergent validity of three of the four subscales.
