BackgroundSuicide among adolescents has become a serious public health issue, with suicidal ideation serving as a necessary precursor to suicide attempts and death. Previous research suggests that campus exclusion, depression, and psychological resilience are closely associated with the development of suicidal ideation in individuals. However, there is a lack of longitudinal research to deeply explore the relationship between each influencing factor and suicidal ideation. ObjectiveTo explore the impact of campus exclusion on suicidal ideation among adolescents, as well as the mediating role of depression and the moderating role of resilience, so as to provide references for formulating strategies for preventing and intervening in adolescent suicide. MethodsAUsing a longitudinal research design, in November 2023, 1 226 students from 21 classes (4 classes per grade in junior high school and 3 classes per grade in senior high school) from a junior high school and a senior high school in a certain area of Shandong Province were selected as the research subjects. The Ostracism Experience Scale for Adolescents (OES-A), the Patients' Health Questionnaire Depression Scale-9 item (PHQ-9), and the Resilience Scale for Chinese Adolescents (RSCA) were used for assessment. The PHQ-9 suicide ideation item was evaluated again three months after the baseline survey (the two suicide ideation evaluations were respectively denoted as T1 and T2 respectively. Spearman correlation analysis was used to examine the relationships among scale scores. Model 4 and model 59 in the SPSS macro program Process 4.2 were used to test the mediating effect of depression between school exclusion and suicide ideation, as well as the moderating effect of psychological resilience on the three paths. ResultsCorrelation analysis showed that OES-A score was positively correlated with PHQ-9 score and suicidal ideation item score (T2), and PHQ-9 score was also positively correlated with suicidal ideation item score (T2) (r=0.361, 0.292, 0.508, P<0.01). RSCA score was negatively correlated with OES-A, PHQ-9, and suicidal ideation (T2) scores (r=-0.500, -0.676, -0.459, P<0.01). Campus exclusion positively predicted suicidal ideation (T2) and depression (β=0.081, 0.281, P<0.01), while depression positively predicted suicidal ideation (T2) (β=0.108, P<0.01). The mediation analysis revealed an effect size of 0.030 (95% CI: 0.019~0.043, P<0.01), accounting for 37.35% of the total effect. Psychological resilience moderated the relationships between campus exclusion and depression, campus exclusion and suicidal ideation (T2), and depression and suicidal ideation (T2) (β=-0.059, -0.049, -0.062, P<0.01). ConclusionA moderated mediation model exists among campus exclusion, depression, resilience, and adolescent's suicidal ideation. Psychological resilience moderates the associations between campus exclusion, depression and suicidal ideation across all three paths.

2.Self-other Agreement on Personality and Moderator Effects of Relationship Quality
Chinese Journal of Clinical Psychology 2001;0(03):-
Objective: To explore self-other agreement on personality and moderation effects of relationship quality.Methods: 114 pairs of previously unacquainted freshmen roommates accomplished the Chinese Personality Scale(QZPS) at the second week and the 15th week subsequent to the initial introduction.Results: Although all self-other agreement coefficients were different for all personality trait scores in QZPS between the 2nd week and the 15th week,some coefficients increased from the 2nd week to the 15th week,others didn’t increased but decreased from the 2nd week to the 15th week,and all the increase was not statistically significant.At the second week,main effects and moderator effects of relationship quality was not significant for all personality traits.At the fifteenth week,main effects of relationship quality were significant for kindness and human relations,and moderator effects of relationship quality were significant for extraversion and ways of life.Conclusion: There is no acquaintanceship effect demonstrated by many western literatures in Chinese culture,but moderator effects of relationship quality are significant in some traits.
