This study aimed to investigate the current status of adversity quotient (AQ) development, develop an instructional model based on Rogers' theory, and assess the impact of the model on students' AQ. The study involved 33 first-year students from infant care services and management majors at Guangxi International Business Vocational College. Research tools included questionnaires, interviews, lesson plans, the Adversity Quotient Scale, observation forms, and interview forms. The study comprised three steps: studying the current situation of AQ development, developing the instructional model, and implementing and improving the model. Data were analyzed using statistical and qualitative methods. Results showed four aspects of existing problems in college students' AQ: students, teachers, learning processes, and environment. The instructional model comprised four components: Principle, Objective, Learning Process, and Result. After implementing the model, students' AQ significantly improved compared to pre-class levels (p < 0.01). This study provides insights into addressing challenges in college students' AQ development and demonstrates the effectiveness of an instructional model grounded in Rogers' theory for enhancing students' AQ. Enhancing college students' adversity quotient is of significant importance for effectively coping with adversity in their daily learning life.
