Construction, Normalization, and Validation of Boshra Test (Cognitive Inhibition Assessment)

Abstract

Cognitive Inhibition, as a component of executive functions, plays an important role in our life. The aim of this research was to construct and validate a new test (Boshra) for measuring cognitive inhibition and impulse control. 225 elementary students (117 girls and 108 boys) were selected through a cluster sampling. Results of test-retest reliability (after two weeks) showed that the Boshra test possessed suitable reliability coefficients. The coefficients were .74 for the interference score and .84 for the time (p<0/001). Furthermore, correlations between the Boshra Test and the Stroop Word-Color Test tend to be moderate; .48 for the interference score and .42 for the time (p<0/001).The calculation of the distribution of scores showed that the distribution of the time and interference scores are almost normal. Results of this research showed that the Boshra test had satisfactory reliability and validity coefficients and it can be a suitable tool for measuring cognitive inhibition and impulse control.
