<b>Investigating the Adversity Quotient and Its Impact on EFL Learners: An Understand-Cultural Study </b>

Mastering a foreign language involves overcoming linguistic challenges, cultural differences, and psychological barriers. The Adversity Quotient (AQ), a concept that measures an individual's ability to cope with difficulties, plays a crucial role in language learning. This study examines AQ levels among Thai EFL learners and explores its influence on their learning experiences. A mixed-methods approach was employed, combining AQ assessments, semi-structured interviews, and focus group discussions. To ensure diverse participation, a randomized stratified sampling method was used, selecting students from different academic years. The findings reveal that learners with higher AQ demonstrate greater resilience, persistence, and adaptability, enabling them to manage setbacks more effectively. Moreover, cultural background significantly impacts how students perceive and respond to learning challenges. The study underscores the importance of integrating AQ-enhancing strategies into EFL instruction to foster perseverance and self-directed learning. The results provide insights for educators and policymakers on creating supportive learning environments that help students navigate adversity in language acquisition.
