Abstract

The present study aimed to investigate the role of executive functions in predicting rational decision-making among adolescents, considering the mediating role of emotional intelligence and moral judgment. Rational decision-making, as one of the key processes of cognitive development in adolescence, plays a crucial role in personal, social, and academic adjustment. Given that adolescence is accompanied by extensive biological, cognitive, and emotional changes, identifying underlying factors influencing rational decision-making is of particular importance. This study employed a quantitative, correlational design using structural equation modeling (SEM). The statistical population consisted of lower secondary school students in Yazd during the 2024–2025 academic year, from which a sample was selected through cluster random sampling. Research instruments included the General Decision-Making Styles Questionnaire (GDMS), the Cognitive Functions Questionnaire, the Trait Emotional Intelligence Questionnaire–Short Form (TEIQue-SF), and the Moral Judgment Questionnaire. Data were analyzed using AMOS-24 software. Findings indicated that executive functions directly predicted rational decision-making (β=0.17, P<0.05). Furthermore, emotional intelligence and moral judgment significantly mediated this relationship (β=0.308, P<0.002). In other words, adolescents with higher executive functions also demonstrated higher levels of emotional intelligence and moral judgment, which in turn contributed to the enhancement of their rational decision-making. The results highlight the importance of an integrated approach to cognitive, emotional, and moral processes in understanding adolescent decision-making and may provide a basis for designing educational and counseling interventions aimed at improving adolescents’ decision-making skills.
