Executive Function Touch battery: Translation and preliminary measure validation for Pakistani preschoolers

Abstract

Keeping in mind the importance of measuring early executive function (EF) skills in low and middle-income countries, the present study examined the feasibility and preliminary psychometric properties of a performance-based computerized EF measure; EF Touch, to be used with Pakistani preschoolers. Review of the content and Urdu translation of verbal instruction EF Touch battery was carried out by subject matter experts before data collection from the 120 preschoolers aged between 3.1 to 5.9 years. The feasibility report indicated that between 79.2% -100% of the preschoolers completed each executive function task. Confirmatory factor analysis revealed the unidimensionality of the EF battery. Item response theory models were used for the initial assessment of tasks and item parameters. Results demonstrated that each task worked invariantly across subgroups of preschoolers residing in low and middle-income households. Moreover, preschoolers showed differences on each task, and task scores reflect their latent EF skills in the low to moderate range. The battery was demonstrated as a feasible and reliable measure for use with low and middle-income countries specifically in Pakistan.
