Cross-cultural Similarities in ADHD-Like Behaviour Amongst South African Primary School Children

Abstract

This study investigates whether the Disruptive Behaviour Disorders (DBDs) rating scale measures the same constructs in South African as in Western cultures, and explores the differences in scale scores as a function of language, gender and age. Teacher ratings between 1997 and 1999 of the 18 DSM-IV symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) in 6 094 primary school children of six language groups in the Limpopo Province of South Africa were collected and analysed. For all language groups, the results were consistent with a two-factor model of ADHD with correlated factors. There were gender and age effects on both scales. The prevalence rates for ADHD sub-types were in line with rates in the United States of America (US) and Europe. Similarities across language groups, as well as to results reported in the US and Europe, were striking. Despite the limitations discussed, teacher ratings of ADHD symptoms on the DBD scale can be used as a screening instrument in South Africa. Separate norms for different language groups are not indicated.
