Psychometric Properties of Barkley's Children and Adolescent Functional Performance Scale

The aim of this study was to determine the reliability, reliability of the Barkley Executive(BDEFS.CA) Teaching and Performance Inventory (2012) in Mashhad. This study is methodological and psychometric study, and uses IQOLA Standard Contracts to test and test Persian language. . For this purpose, multistage cluster sampling method was used to select 1000 primary school students (6 to 17 years old) in Mashhad in the academic year of 96-97 and 979 students completed the questionnaire. , 63 of them were asked to participate in the test two weeks ago. The reliability of the test was determined using Cronbach's alpha, 0.90. The split coefficient, with the test, was used to calculate the correlation coefficient of this test with the Coolidge test (Zahedi and Alizadeh, 2004) in a sample of 200 people. In the judgmental phase, we conducted several local field studies and non-standard pilot administrations. For the statistical phase, the provided materials. In validity analysis, strong correlations were found among the majority of the scores within the tests; correlations between various (BDEFS.CA) tests were in the range of weak to moderate; the adapted tests show acceptable psychometric properties in assessing the complex, multidimensional construct of executive functioning. For the whole scale of executive functions and sub-components of self-management, self-organizing / problem solving, self-control / inhibition, self-motivation and emotional self-regulation, alpha coefficients are equal to 0.91, 0.85, 0.82, 0.78 , 0.76 and 0.72. which have almost high coefficients and represent the sustainability of the scale of executive function
