computer based stroop animal size test in children: construction, validation and psychometric properties

Objective: an important cognitive control process is the ability to inhibit, that mature at different rates during childhood to adolescence. the aim of our research was to construct and validate computer-based stroop animal size test in children for measuring selective attention and response inhibition.research methodology: in this survey study, we prepared the test, after the approval of experts and software development, at first test-retest reliability with a two week was evaluated in a separate sample (n=50, 5-12 years old children), then data was collected from 92 children 5-12 years old (46 girls and 46 boys) included 22 children with attention deficit/hyperactivity disorder (adhd) studied in the academic year 2022-2023 in alborz province. participants decided the real size of animals by pressing response keys on computer. anova, multivariate analysis, pearson correlation coefficients and cronbach α were used to assess reliability and validity (p<0.05).findings: the findings showed test-retest reliability in significant range (p<0.01). the correlation was high for stroopnum, (r=0.83), inconsistent answers, (r=0.72), wrong answers, (r=0.89) but lower for consistent answers, (r=0.28) and reaction time, (r=0.41). to assess the internal consistency, cronbach alpha 0.91 computed. anova analysis for comparing children’s function in different age groups was (p<0.000).conclusion: multivariate analysis was used in comparing children with adhd to the control group, results showed significant difference between groups in stroop components, (p<0.007). this computerized stroop animal size test had satisfactory reliability and validity, that can measure cognitive functions such as selective attention and inhibition in children.
