Computer based Stroop Animal Size Test in Children: Construction, Validation and Psychometric Properties (مقاله علمی وزارت علوم)

چکیده

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.
