Construction and validation of Persian computer version of Numerical Stroop test in students

The aim of this study was to construct and validate the Persian version of the numerical stroop test in students. The research method is descriptive-survey of construction and validation type. The study population was the second grade elementary students of Arak (fourth, fifth and sixth grades), 315 students were selected by multi-stage cluster sampling. The numerical stroop computer test was developed in Delphi. The tools of color-word stroop test, Raven’s IQ test and Connors Teacher Rating scale were used. The content validity of the test made by experts was confirmed. The convergent validity of the constructed test was also assessed using the color-word Stroop test. The convergence of the color-word stroop test with the numerical stroop section was 0.78 and with the physical stroop section was 0.71. The reliability of the designed student retest with a time interval of 21 days was also 0.88. Considering the research findings, it can be concluded that numerical strop test is a suitable cognitive tool and it can be used in future research to examine selective attention in various educational disorders such as learning disorders and other mental disorders.
