Abstract:
The purpose of the study was to determine the validity and reliability of the Child and
Adolescent Disruptive Behaviour Inventory (CADBI) developed by Burns (2001).In the study
Quasi-experimental research design was applied. Purposive sampling was applied to identify the
two schools. A sample size of 180 children aged between 9 and 14 years and who met diagnostic
criteria for ODD was used. The respondents in the experimental group were treated using CBT
for a period of three months while those in the control group did not receive any intervention.
Demographic characteristics of the respondents were captured using questionnaires while
teachers and parents of the children completed the Child and Adolescent Disruptive Behaviour
Inventory (CADBI) V.2.3. The inventory had two forms CADBI: Parent (25 items) and CADBI -
Teacher (25 items), each comprised of 3 subscales including Oppositional Defiant Disorder
toward Adults, Oppositional Defiant Disorder toward Peers/Siblings, Attention Deficit
Hyperactivity Disorder. First the teachers and the parents completed the forms of the selected
sample of children aged 9 to 14 years. The reliability and validity was determined. An all item
test for reliability was done using the Cronbach’s alpha values and Kaiser-Meyer-Olkin (KMO)
values in factors analysis. The CADBI tool showed Cronbach’s alpha and KMO scores ranging
from 0.8 to 1.0 indicating great and superb scores confirming the reliability of results both across
and within the two groups. The study has implication in the field of child clinical psychology
