The Denver II Scales and the Griffiths Scales of Mental Development: a correlational study

Abstract

Screening measures aim to minimise the number of children being diagnosed incorrectly; however, many of these measures have been based on the “normal” white population. This study identified the need for a valid developmental assessment of black preschool children. The general aim of the study was to investigate the use of the Denver II and the Griffiths Scales on a pre-school black Xhosa-speaking sample. Specifically, the aim was to investigate the relationship between the Denver II Scales and the Griffiths Scales, in order to provide the first step in establishing the validity of the Denver II Scales on a South African black population. A correlational design was used and the sample was comprised of 60 Xhosa-speaking children between the ages of 3 and 6 years. The findings revealed that there was a significant relationship between the overall performance of the Denver II and the Griffiths Scales. However, the Personal-Social Scale of the Denver II appeared to have items that were culturally biased. Further, the Denver II further identified a higher percentage of the sample to have abnormal or questionable protocols than the Griffiths Scales did.
