Emotional Intelligence and Cognitive Flexibility as Predictors of Academic Success and Adaptation Outcomes Among International Students in Saudi Universities

International students in Saudi universities face academic and adaptation challenges shaped by emotional, cognitive, linguistic, and sociocultural factors. This study examined whether emotional intelligence and cognitive flexibility predicted academic success and adaptation outcomes among international students in Saudi public universities. A quantitative cross-sectional survey was conducted with 410 international students using structured measures of emotional intelligence, cognitive flexibility, academic success, adaptation outcomes, Arabic proficiency, and sociodemographic characteristics. Data were analysed using descriptive statistics, chi-square tests, Kendall’s tau-b correlations, hierarchical regression, and observed-variable path analysis. Duration of residence was significantly associated with Arabic proficiency, χ2(8) = 82.40, p < .001. Arabic proficiency was positively associated with GPA, τ = 0.62, p < .001, and adaptation outcomes, τ = 0.48, p < .001. In hierarchical regression, sociocultural covariates and psychological predictors explained substantial variance in academic success, R2 = 0.53, and adaptation outcomes, R2 = 0.53. Emotional intelligence and cognitive flexibility remained positive predictors of both outcomes after accounting for Arabic proficiency, duration of residence, region of origin, and language of instruction. Findings suggest that international student success in Saudi universities reflects an interaction of emotional, cognitive, linguistic, and contextual resources. Universities should strengthen integrated support for emotional regulation, adaptive thinking, Arabic-language development, and culturally responsive academic guidance.
