SUMMARY
Validity, Reliability and Normative Data of the Stroop Test Çapa Version

Objective: The Stroop test Çapa version does not have normative
data, despite its extensive use in clinical and research settings to assess
executive functions. The aim of the present study was to test the validity
and reliability of the Stroop test Çapa version and to establish stratified
normative data in individuals aged between 18-83 years.
Method: The norm determination phase of the study included 541
healthy participants, stratified by age, education, and gender. The
relative contributions of the demographic variables on the completion
times of Stroop subtests were assessed with multiple linear regression
analysis. The main effects of age, education and gender variables and
of interactions between these on the completion times of subtests were
investigated with 6x3x2 ANOVA design. In addition, the concurrent
validity, test-retest reliability and internal consistency of the test were
examined.
Results: Multiple linear regression models that included age and
education accounted for 23-42% of the completion time variances of
all subtests. In the factorial ANOVA, main effects, as well as interaction
effects of age and education were found on all subtests. For all Stroop
subtests, the completion times were the shortest for the individuals in
the 18-29 age group with the highest education level and longest for the
individuals in the 70-83 age group with the lowest education level. The
test demonstrated acceptable internal consistency and high test-retest
reliability.
Conclusion: Normative data of the Stroop Test Çapa Version were
provided for the assessment of executive functions in young and middleaged adults and elderly population.
