Purpose: Our study validated the Ten Question Questionnaire (TQQ+) for Bangladeshi children between 10 and 16 years. The TQQ + is a rapid screening tool for disability and was previously validated in children below 9 years of age.
Materials and methods: The study was carried out in Chattogram, Bangladesh. One hundred children aged 10-16 years, 10 with mild or moderate disabilities, 40 with severe disabilities, and 50 children without a disability were identified. Children with disability (n = 50) had previously undergone Wechsler Intelligence Scale-Revised (WISC-R) assessments by psychologists as a reference standard. Each child was evaluated using Rapid Neurodevelopmental Assessment (RNDA) by physicians and TQQ + was administered by researchers. Sensitivities and specificities of TQQ + were evaluated in comparison with RNDA and WISC-R.
Results: The sensitivity of TQQ + was 98% in comparison with either RNDA or WISC-R. The specificity of TQQ was 76.5% compared with RNDA and 78% with WISC-R. TQQ + successfully picked up cognitive (98%) and motor (75%) disabilities as well as behavioural problems (88.9%). Specificity was good to excellent in all other domains. Logistic regression showed that TQQ + could reliably predict disability by RNDA and WISC-R. The area under the Receiver Operating Characteristic Curve (ROC) curve was 0.88 which denoted good diagnostic accuracy of the questionnaire.
Conclusion: The TQQ + is valid for screening disabilities in 10-16 year old Bangladeshi children.IMPLICATIONS FOR REHABILITATIONIf children with neurodevelopmental disabilities are screened early, the benefit of intervention will be greater.TQQ + is an easy to administer and low-cost tool that has been validated internationally.The TQQ + is now validated and can be used for children aged 10 to 16 years in Bangladesh.
