Investigation of the validity and reliability of the Turkish form of the Adult Executive Functions Inventory (ADEXI)

Summary/Abstract: This study aimed to examine the psychometric properties of the Turkish Version of the Adult Executive Functions Inventory (ADEXI), which was developed to evaluate executive functions from adults. The sample of the study consisted of 376 participants aged between 18 and 65 (Mean = 20.59, SD = 1.84) and selected from the community sample. The participants filled out the Demographics Form, Cognitive Flexibility Inventory, Barratt Impulsivity Scale, Adult Attention Deficit Hyperactivity Disorder Self-Report Scale, and the Turkish version of ADEXI. The two-factor structure (working memory and inhibition) in the original version of the scale was confirmed by second-level confirmatory factor analysis. ADEXI’s association with other meas-urement tools were also observed. Cronbach's alpha internal consistency coefficients for the total score of the scale and for the working memory and inhibition dimensions were calculated as .80, .83, and 73, respectively. Moreover, Gutman's two-half reliability coefficients for the total score of the scale and working memory and inhibition dimensions were calculated as .75, .81, and .69 respectively. Results showed that the Turkish version of ADEXI is a valid and reliable measure-ment tool that can be used to evaluate two dimensions of executive functions, working memory and inhibition.
