SAGE Open, v11 n3 Jul-Sep 2021
The aim of the present study is to develop a national non-verbal cognitive ability test in Turkey. Test items were developed during the first stage and applied as a pilot study on 3,073 children in the age interval of 4 to 13. The test was given its final form based on the values of item difficulty, item distinctiveness, item total score correlation. Norm study was carried out at 12 different provinces with a total of 9,129 children comprised of 4,464 females (49%) and 4,665 (51%) males. Test-retest, split-halves, KR-20, and KR-21 methods were applied for the reliability analyses of the study. Standard error, standard deviation, and reliability coefficient were calculated for the measurement. Content and construct validity along with criterion-related validity analysis methods were used for validity analyses. The KR-20 reliability coefficient obtained from the complete sample group was estimated as 0.92. Test-retest reliability coefficient was determined as 0.80. A correlation of .71 was determined between Naglieri Cognitive Ability test and BNV test. A correlation of .67 was determined between Toni-3 test and BNV test while a correlation of .86 was determined between BNV and Colored Progressive Matrices Test.
