ABSTRACT
This study investigated the potential implications of optimism and mental health in promoting independent learning among Chinese university students using a theoretical model related to loneliness, optimism, mental health, independent learning, and academic achievement and the relationships between them. Valid data were obtained from 509 participants from four universities in Wuhan, China, through a questionnaire with five-point Likert scales specific to loneliness, optimism, mental health, independent learning, and academic achievement in September 2021. These data were used to construct models to test measurement validity and mediating mechanisms through structural equation modeling. The results revealed that loneliness influences mental health, thereby influencing the academic achievement of Chinese university students, and optimism can reduce the partial negative effect of loneliness on students’ mental health. Good mental health can support independent learning to promote academic achievement. This study provides recommendations for university managers to promote independent learning among Chinese university students.
