Participants for this study were recruited from three general elective courses in a university in Shandong Province. Participants were required to complete four questionnaire measurements, each approximately one month (4 weeks) apart. The initial measurement involved 198 participants, with a few students dropping out during the following three measurements. Ultimately, only data from participants who completed all four measurements were retained, resulting in a total of 194 participants. Descriptive statistics were computed using SPSS 18.0, while cross-lagged model analysis was performed using Amos 24.0.
