Abstract

Since the introduction of the Griffiths Scales of Mental Development (Griffiths Scales) to South Africa, extensive research has been conducted in both clinical and educational settings. The measure is currently undergoing revision, with one of the objectives being to explore its psychometric properties, in particular its construct validity. The aim of this study was to examine the underlying dimensions tapped by subscales A, B, C, D, E and F for years 5, 6 and 7. The sample consisted of 180 children between the ages of 48 and 60 months, 60+ and 72 months, and 72+ and 84 months for years 5, 6 and 7 respectively. The variables of gender, cultural group and central nervous system development were controlled for. Underlying factors in each subscale were identified by means of factor analysis. The findings suggest that each subscale taps more than one construct and that constructs differ for the different age groups. This implies that in the revision process subscales for each of the years need to be investigated further with regard to their construct validity.
