The advent of the "positive psychology turn" in applied linguistics has brought increased attention to psychological constructs such as hope, which significantly impact students’ academic performance, including their effort. However, the intricate relationships among these factors remain underexplored. To address this gap, the present study employs a mixed-methods approach to investigate how specific dimensions of students' hope influence their efforts. A sample of 711 Chinese senior high school students studying English as a foreign language participated by completing questionnaires assessing their levels of hope and effort. Findings from structural equation modeling indicate that pathways, a dimension of hope, directly and positively affect students' efforts in learning a foreign language. This research provides valuable insights for educators, highlighting the importance of fostering hope in English learning to enhance students' strategic approaches to language acquisition and support their academic progress.
