Abstract
This study examines the effect of Cognitive Behavioural Therapy (CBT) on behavioural
challenges among Basic Four pupils with Down syndrome in Jos Metropolis, Plateau State,
Nigeria. Down syndrome is associated with cognitive, motor, and behavioural difficulties that
impact learning and social interactions. This study employed a true experimental design with
a pre-test, post-test control group to investigate the effectiveness of CBT in reducing
oppositional behaviour disorder, attention behaviour disorder, and social withdrawal
disorder. A sample of 12 pupils was selected, with six assigned to the experimental group
receiving CBT and six in the control group receiving regular instruction. Data was collected
using the Behaviour Disorder Checklist (BDC) and analysed using the mean, standard
deviation and t-test of independent samples. Results indicate a significant reduction in
behavioural challenges among the experimental group compared to the control group. The
study concludes that CBT is an effective intervention for improving behaviour among children
with Down syndrome and recommends its integration into special education programmes and
therapeutic interventions.
