Stroop color and word test (SCWT): Normative data for the Lebanese adult population

Abstract

The Stroop Color and Word Test (SCWT) is one of the most commonly used measures to assess multiple cognitive functions. Several studies have shown that SCWT performance is influenced by different demographic factors and have recommended the necessity of generating normative data in different cultures. The present study aims to explore the effect of gender, age, and education on SCWT scores and to generate normative data for the Lebanese healthy adults. A sample of 321 healthy participants aged 18 and above was recruited from different Lebanese regions. The SCWT was administered to the participants. A regression-based strategy was applied to generate normative data. The results showed a statistically significant effect of age and education on the SCWT scores whereas no significant effect for gender was found. An interactive calculator was created to calculate estimated Z-scores based on corresponding predictions of the linear regression model. The calculator also provides percentile ranks. The present study is the first to generate normative data for the SCWT test in Lebanon. Neuropsychologists in Lebanon will benefit from this outcome to improve the accurate detection of executive function deficits in clinical settings for the Lebanese adult population.
