The validity and reliability study of the theory of mind inventory-2 (TOMI-2) Turkish version

Abstract

This study aims to conduct the Turkish adaptation, validity, and reliability study of the Theory of Mind Inventory-2 (TOMI-2) developed by Hutchins and Prelock (2016) for 3-5-year-old children. The study group consists of 310 mothers with children in the 3-5 age group in Konya city center. Personal Information Form and Theory of Mind Inventory-2 (TOMI-2) were used as data collection tools in the study. After the TOMI-2 was translated into Turkish, the normality assumption was checked with the "Shapiro-Wilk" test. The relationship between two continuous variables was evaluated with the Pearson Correlation Coefficient. Exploratory Factor Analysis, Confirmatory Factor Analysis, Content Validity, Criterion Validity, and Reliability analyses were also used in the study. The findings of the analyses show that the Turkish version of the TOMI-2 is a valid and reliable measurement tool for children aged 3-5, with 60 items in the original form.
