Inclusion/Exclusion criteria
Children aged 6-12 years were enrolled provided guardians demonstrated ability to read and write in English. A written signed informed consent was also required from the primary care provider. Children on methylphenidate, antidepressants or behavioral therapy and those with neurological disorders, hearing and visual impairments or need for emergency care were excluded. Those who consented were clinically evaluated and treated for the ailments that brought them to hospital prior to completion of the self-administered study questionnaire.
Sample size was estimated at 240 based on estimated ADHD prevalence of 6% reported by Kashala et al. [5] from a neighboring country with similar socio-economic setting as Kenya.
