Correction to: A Systematic Review of the Validity and Reliability of Assessment Tools for Executive Function and Adaptive Function Following Brain Pathology among Children and Adolescents in Low- and Middle-Income Countries

Minimal but increasing number of assessment instruments for Executive functions (EFs) and adaptive functioning (AF) have either been developed for or adapted and validated for use among children in low and middle income countries (LAMICs). However, the suitability of these tools for this context is unclear. A systematic review of such instruments was thus undertaken. The Systematic review was conducted following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) checklist (Liberati et al., in BMJ (Clinical Research Ed.), 339, 2009 ). A search was made for primary research papers reporting psychometric properties for development or adaptation of either EF or AF tools among children in LAMICs, with no date or language restrictions. 14 bibliographic databases were searched, including grey literature. Risk of bias assessment was done following the COSMIN ( CO nsensus-based S tandards for the selection of health status M easurement IN struments) guidelines (Mokkink et al., in Quality of Life Research, 63 , 32, 2014 ). For EF, the Behaviour Rating Inventory of Executive Functioning (BRIEF- multiple versions), Wisconsin Card Sorting Test (WCST), Go/No-go and the Rey-Osterrieth complex figure (ROCF) were the most rigorously validated. For AFs, the Vineland Adaptive Behaviour Scales (VABS- multiple versions) and the Child Function Impairment Rating Scale (CFIRS- first edition) were most validated. Most of these tools showed adequate internal consistency and structural validity. However, none of these tools showed acceptable quality of evidence for sufficient psychometric properties across all the measured domains, particularly so for content validity and cross-cultural validity in LAMICs. There is a great need for adequate adaptation of the most popular EF and AF instruments, or alternatively the development of purpose-made instruments for assessing children in LAMICs.
