This study investigates the relationship between self-control, self-esteem, and self-efficacy among university students and their use of artificial intelligence (AI) tools. The research is cross-sectional and includes 1,761 undergraduate students from education and psychology programs. Data were collected using validated self-reports, and analyses were conducted to explore the associations between these psychological traits and AI tool usage. Key findings include: - Low self-control is significantly associated with higher frequency of AI tool use. - Self-control and self-efficacy are linked to using AI to solve daily doubts and academic tasks. - Higher self-esteem is associated with lower odds of using AI for social interaction. - Male gender is also associated with higher AI tool use. The study suggests that educators should consider these findings when integrating AI into educational strategies to promote responsible and effective use among university students. The results highlight the importance of addressing self-control, self-esteem, and self-efficacy in the context of AI tool usage to ensure ethical and beneficial educational practices.This study investigates the relationship between self-control, self-esteem, and self-efficacy among university students and their use of artificial intelligence (AI) tools.
