- Description: The health status of a substantial number of South African children can be classified as “children at risk” (Luiz, 1999) as the majority of children are influenced by factors such as poverty, poor living conditions and the HIV/AIDS epidemic. These are only some of the influences that contribute significantly to the health status of South African children and consequently their development. It can thus be argued that developmental assessment is imperative in the South African context. One of the most important reasons are that children with special needs in South Africa can be identified and given the opportunity to catch up developmentally and cope successfully as opposed to those who are identified much later (Foxcroft & Roodt, 2006). Furthermore, children in South Africa must begin Grade one in the year in which they turn seven. They may only enter grade one if the school has an opening and if the necessary evidence is provided to the Department of Education that the child will be able to cope with the demands of formal schooling (Department of Education, 2002). Developmental assessment measures therefore needs to be appropriate, accurate and informative in the modern South African context. The need for a measuring instrument to assess children’s overall development and thus their developmental readiness to cope with the demands of formal schooling could be satisfied by the Griffiths Mental Development Scales – Extended Revised (GMDS-ER). This recently revised measure has not been normed on a representative, contemporary South African sample. The purpose of the study was therefore to generate information on the applicability of British norms for the contemporary South African population. This study compared and explored the performance of South African and British children aged 5-years and 6-years on the Griffiths Mental Development Scales - Extended Revised (GMDS-ER). A contemporary South African sample was obtained by testing children between the ages of 5-years and 6-years on the GMDS-ER, whilst the British sample was drawn from the United Kingdom and Eire standardization sample. The British sample was screened for normality and a similar process was followed to establish normality for the South African sample. A matched simple frequency distribution technique (taking into account age, socioeconomic status and gender as variables) was employed to approximate the equivalence between the samples. The profiles were compared by conducting an independent sample t-test with subsequent post hoc analyses to explore potential differences in the performance of the two samples. The major findings of the present study were as follows: 1. There is a significant difference between the South African and British children’s overall developmental profiles (as measured by the GMDS-ER). 2. Generally, South African children performed better on the Locomotor subscale and the Personal Social Subscale (although not statistically significant), whilst British children performed statistically better on the Language, Eye and Hand Co-ordination, and Practical Reasoning Subscales. 3. No significant differences were found for the Performance Subscale which could indicate that South African and British children’s performances on this scale are similar. Further investigations into the applicability of the GMDS-ER for the contemporary South African context are recommended and the establishment of South African norms for clinical utilization is essential. Caution with regard to the utilization of the British–based norms in the South African context is final recommendations.

- Description: The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.
