Factor analysis of the Children's Behaviour Questionnaire in a Nigerian paediatric primary care population

Abstract

Objective. This paper examines the factor structure of the Yoruba translation of the Children's Behaviour Questionnaire for Completion by Parents (CBQ) adminstered in a Nigerian paediatric primary care population. Design. A corss-sectional questionnaire survey. Subjects. Four hundred and seventy-eight children aged 7 - 14 years who attended a primary care clinic in Ibadan, Nigeria, over a 3-month period. Methods. Parents' ratings of the children were obtained using the Yoruba translation of the CBQ. The factor structure of this instrument was examined using principal component analysis with varimax rotation. Only factors with eigenvalues of greater that 1 were examined further. Results. The first seven dimensions were readily conceptualised. These factors are conduct problem, hyperactivity, emotional problem, irritability, problems with elimination, a somatic complaint and a school problem dimension. Conclusion. These factor are similar to what has been observed in other studies involving populations of children with psychopathology, with the exception of the somatic complaint and school problem dimension. The emergence of these two factors, which are quite different from what has been observed in other studies, may demonstrate differences that reflect the influence of language, culture and the peculiarities of a primary care setting. On the other hand the similarity of most of the factors to those found in previous studies confirms the broad similarites in the behaviour of children across different cultures.
