Abstract
<h4>Background: </h4> Neurodevelopment assessment tools for low-resource settings are urgently needed. However, most available tools were developed in high-income settings and may lack cross-cultural validity. <h4>Methods: </h4>: We piloted and adapted two subtests (pattern reasoning and story completion) within the Kaufman Assessment Battery for Children-2 nd edition (KABC-II) for use in rural Zimbabwean children aged 7 years old, both within the planning domain. After initial assessments of face validity, we substituted and added items in the test battery through a co-design process with fieldworkers and child development experts. To assess how successful the changes were, T-tests adjusting for unequal variances were used to compare scores between the original and adapted versions of the same subtest. ANOVA and pairwise analysis was performed to compare the performance of KABC-II subtests across domains. Intraclass correlation coefficient was calculated to explore the variability between domains. <h4>Results: </h4>: Initial test scores on the planning domain were significantly lower than the other three domains of learning, sequential memory and simultaneous reasoning (P<0.001) in 50 children. Modified subtests were administered to another 20 children, who showed story completion scores that were 0.7 marks higher (95% CI 0.0, 1.4; P=0.05) and pattern reasoning scores 1.8 marks higher (95% CI 0.5, 3.2; P=0.01). Overall, the planning domain mean score increased from 8.1 (SD 2.9) to 10.6 (SD 3.4). The intra class correlation coefficient between all four KABC-II domains was initially 0.43 (95% CI 0.13, 0.64) and after modification was 0.69 (95% CI 0.37, 0.87), suggesting an increase in the construct validity. <h4>Conclusions: </h4>: The KABC-II planning domain was successfully adapted to improve cross-cultural validity. Construct validity was enhanced, based on increased inter-correlations among scales. This pilot has since been applied to the SHINE follow-up study. The process of co-design to modify tests for new settings may be beneficial for other commonly used neurodevelopmental tools.
