Personality traits and demographic factors can shape security behavior intentions. The impact of these factors on security behavior intentions can vary based on the cultural context in which individuals reside. In this study, we explore cultural variations in security behavior intentions, followed by an analysis of the personality traits and demographic factors that can predict these intentions. We investigate Arab local and Arab ex-pats in Europe and European populations, analyzing the varying effects of predictors on each group. Data was collected from 513 participants through an online survey. Age, gender, need for cognition, and personality traits, including agreeableness, conscientiousness, and neuroticism, were used to predict security behavior intentions. The findings reveal a slight inclination among Arab individuals towards higher security behavior intentions than Europeans, with varying impacts of predictors observed between the two samples. These findings significantly enrich the existing literature by including cultural factors and studying populations not WEIRD (Western, Educated, Industrialized, Rich, and Democratic). The research identifies predictive factors and their strength, covering diverse populations across Arab and European countries to comprehensively understand these dynamics.
