Theory of Mind Test for Children: Content Validity

Abstract In the national context, there is a lack of instruments to evaluate Theory of Mind, especially with studies of their psychometric properties. This study aimed to investigate content validity evidence for the Theory of Mind Test for Children - TMEC. The development steps, analysis by expert judges and verification of the applicability of the instrument in children aged between 4 and 6 years are described. The TMEC was organized into 4 subtests, following the tasks model described in the literature. Next, 5 judges investigated the clarity of the instructions, the registration form and the score, the level of difficulty of the items and the need for changes. Items highlighted by the judges were reformulated, following the criterion of at least 80% agreement. The applicability of the instrument in a group of six preschool children was verified, which indicated the need to reword a few items for better understanding of the applicator and the child.
