Psychometric Properties Of Bender – Gestalt(II) Test In Primary School Students

Visual-Motor skill is essential for human development and an important part of psychological evaluations and allows a person to have sufficient interaction with her environment. In order to measure this important skill, it is better to use an objective and standard tool. Since for each psychological assessment tool, it is necessary to check the psychometric properties. The aim of the current research is to investigate the psychometric properties of B.G.V.M.T (2) in students aged 6 to 12 years. The current research was applied in terms of objective and descriptive research method of correlation type. The statistical population of the present study included all primary school students in the 4 educational districts of Qom in the academic year 1400-1401, which were selected by multi-stage cluster sampling, 374 girls and 444 boys from 8 schools. For the reliability of the test, retesting and dividing methods were used. The reliability coefficient obtained from the retesting of the test in the copy and recall phases was 0.85 and 0.78, respectively, and the average reliability coefficient was 0.67. To measure the validity of the test from 3 methods[calculating the correlation coefficients between the test scores of B.G.T (2) and Andre Ray and the inclusive scoring system and Koppitz, comparing the performance of children with and without learning disorders] was used. In general, according to results of the reliability and validity research conducted in this research, we can consider the B.G.T (2) with a G.S.S as a useful tool for measuring V.M ability of children.
