The rapid proliferation of smartphone technology has transformed learning environments, particularly within vocational domains such as hospitality and catering education. While mobile devices offer pedagogical advantages, excessive reliance has contributed to psychological conditions such as nomophobia—defined as the fear or anxiety of being without a mobile phone. This study develops a behavioral model to investigate smartphone addiction patterns and nomophobia among students in hospitality and catering education contexts. Drawing upon interdisciplinary theoretical frameworks, including behavioral dependency theory, technology acceptance models, and psychosocial constructs, the study synthesizes existing empirical findings to conceptualize key influencing variables such as self-esteem, loneliness, learning environments, and digital engagement patterns. A structured methodological framework is proposed, integrating quantitative and behavioral analysis approaches to evaluate addiction patterns and their academic implications. The findings highlight significant correlations between smartphone dependency, cognitive distraction, and reduced practical skill acquisition in culinary education. The study further identifies contextual factors unique to hospitality training environments that intensify nomophobic tendencies. The research contributes to academic discourse by presenting a domain-specific behavioral model and offering actionable insights for educators, policymakers, and curriculum designers. Limitations and future research directions are also discussed.
