In order to explore the influencing factors of the study engagement of junior high school students, 148 junior high school students in Xi\'an City were measured continuously for 9 days. The results showed that: (1) Study engagement is negatively correlated with time pressure while positively correlated with psychological capital and sleep quality; (2) The sleep quality of male students was significantly higher than that of female students, and the sleep quality was positively correlated with psychological capital and negatively correlated with time pressure. (3) Psychological capital and sleep quality all play a moderating role in the relationship between time pressure and study engagement of Grade 1 students; The results of this study reveal the effects of time pressure, sleep quality, and psychological capital on first-year students\' engagement in studying, and provide a basis for the implementation of the "double reduction" policy.
