In the third stage, all students were subjected for detailed clinical work-up.Statistical Analysis:Criterion validity of the tools used and their comparison.Result:GHQ had high sensitivity and specificity compared to CPMS in relation to clinical interview.Conclusion:It is found that GHQ is a better screening tool than CPMS in children aged between 13 and 14 years.
