Replication Data for: Utility of the 3Di short version in the identification and diagnosis of autism in children at the Kenyan Coast

We conducted this study to (i)evaluate the reliability of the Swahili version of the 3Di-sv in the detection of autism in children from rural Kenyan settings; (ii) determine the factorial structure of Swahili 3Di-sv, (iii) investigate the measurement invariance of the Swahili 3Di-sv in these settings; and (iv) compute the criterion validity of the Swahili 3Di-sv while comparing its scores against the diagnosis from either DSM-IV-TR or DSM-5. This study was carried out in a defined area, the Kilifi Health and Demographic Surveillance System (KHDSS), in Kilifi County on the Kenyan coast. This study was nested in a large epidemiological study (NDD Study) that screened 11,223 children randomly selected from 28,000 children aged 6 to 9 years within the KHDSS. 11,223 children were successfully screened with the INCLEN neurodevelopmental disorders screening tool (NDST) in stage I. There are eight autism-specific questions in the NDST. Approximately 2,162 children from stage I were invited for further clinical and neuropsychological assessments, including administration of the ADOS (targeted to a proportion of children screening positive in autism-specific questions) and 3Di (targeted to every child in stage 2).
