Psychomotor development in two-year-old Ivorian and Ghanaian children - Psychometric properties of the Kilifi Developmental Inventory

The assessment of psychomotor development in young children from low- and middle-income countries is impeded due to the lack of tools specifically designed for these resource-constrained contexts. This cross-sectional study aimed at analysing the measurement properties of the Kilifi Developmental Inventory (KDI) in two-year-old children. We administered the KDI to 289 children from Côte d'Ivoire and 230 children from Ghana. The postulated internal structure with two first-order latent variables (locomotor performance and eye-hand coordination) that loaded on a second-order latent variable (psychomotor functioning) was supported. The reliability of most factors and scales was sufficient. Interrater reliability of most items was acceptable. Correlations were weak between the scale scores and age and gender, respectively. The findings are limited by the restricted age range of the sample. Overall, the KDI showed promising measurement properties for the assessment of psychomotor performance in children from sub-Saharan countries.
