Objective: To explore the longitudinal relationship between upward social comparison and online aggressive behavior among college students, in order to provide an empirical evidence for educators to carry out mental health promotion for college students. Methods: From December 2021 to March 2022, 539 college students from one university in Inner Mongolia were recruited to complete the Upward Social Comparison Questionnaire (USCQ) and Online Aggressive Behavior Scale (OABS) in a 4 month follow-up study. The structural equation model was used to conduct cross-lagged analysis. Results: The mean scores of upward social comparison for college students tracked at baseline (T1) and 4 months follow-up (T2) were (2.77±0.93, 2.70±1.00) points, and the mean scores of online aggressive behavior were (1.06±0.13, 1.05±0.11) points. There were positive relations between upward social comparison and online aggressive behavior of college students at both cross-sectional levels ( r=0.14-0.19, P <0.05). In the autoregression, T1 upward social comparison could positively predict T2 upward social comparison ( β =0.66), and T1 online aggressive behavior could positively predict T2 online aggressive behavior ( β =0.47)( P <0.01); In the cross-lagged regression, T1 upward social comparison could positively predict T2 online aggressive behavior ( β=0.10, P <0.01), whereas T1 online aggressive behavior could not predict T2 upward social comparison ( β=0.04, P >0.05). Conclusion Upward social comparison is the cause of online aggressive behavior among college students. The probability of online aggressive behavior among college students should be reduced by guiding students to correctly view the gap between themselves and others.

Objective: To explore the longitudinal mediating role of dispositional envy between upward social comparison to social networking and depression in college students, so as to provide a reference for depression prevention in college. Methods: Using convenience cluster sampling, a total of 1 487 college students from 7 universities in Inner Mongolia Autonomous Region and other provinces of China were recruited to participate in a three month longitudinal study, which contained 3 waves of date collection in September 2019 (T1), October 2019 (T2) and November 2019 (T3). These college students were surveyed with Social Network Site Upward Comparison Questionnaire, Dispositional Envy Scale and Depression Scale. Correlations analysis, missing value and common method biases were performed with SPSS 25.0. Confirmatory factor analysis and longitudinal mediation analysis were performed by Mplus 8.3. Results: The detection rates of depression of college students in the first to third (T1-T3) wave were 3.6%, 4.2%, and 2.8% . The upward social comparison to social networking (T1:2.81±0.94, T2:2.69±0.99, T3:2.47±1.06), dispositional envy (T1:1.97±0.75, T2: 1.87 ±0.74, T3:1.76±0.75) and depression (T1:1.81±0.66, T2:1.74±0.65, T3:1.68±0.69) of college students showed a decreasing trend, and time main effects were statistically significant ( F=71.97, η 2=0.050; F=57.84, η 2= 0.040 ; F=39.64, η 2= 0.030 , P <0.01). T1 upward social comparison to social networking significantly predicted T2 dispositional envy ( β =0.25); T1 upward social comparison to social networking significantly predicted T3 depression ( β =0.10); T2 dispositional envy significantly predicted T3 depression ( β =0.55), showing that the longitudinal mediating role of dispositional envy was statistically significant ( P <0.01), the indirect effect accounted for 58.3%. Conclusions College students upward social comparison to social networking indirectly affects depression through the dispositional envy. Intervening dispositional envy could reduce college students depression levels in the future.

Objective:To investigate the relationship between childhood abuse experience and suicide attitude among male prisoners, and the mediating effect of impact of event and thought suppression.Methods:Totally 370 male prisoners were tested by personal report of childhood abuse(PRCA), impact of event scale(IES), white bear suppression inventory(WBSI) and suicide attitude inventory(SAI). SPSS 22.0 was used for correlation analysis, regression analysis and other statistical analysis.Results:The scores of PRCA, IES, WBSI and SAI were (2.60±0.62), (2.69±0.62), (2.83±0.79), (3.06±0.61), respectively.There were significant differences in the scores of PRCA, IES and WBSI among different suicide attitude groups( F=42.69, 51.06, 78.76, all P<0.01). After controlling age variables, positive correlation was observed between PRCA, IES, WBSI and SAI ( r=0.38-0.76, all P<0.01). Impact of event and thought suppression played a mediating role in the relationship between childhood abuse experience and suicide attitude among male prisoners.The mediating effect included three paths: one was the single mediating effect of impact of event, the other was the single mediating effect of thought suppression and the third was the chain mediating effect of impact of event and thought suppression, and the effect values were 0.29, 0.23 and 0.05, respectively. Conclusion:Childhood abuse experience not only directly influences male prisoners' suicide attitude, but also indirectly influences their suicide attitude through the mediating effects of impact of event and thought suppression.

Objective:To explore the mediating role of negative cognitive processing bias between pathological narcissism and interpersonal conflict of college students.Methods:The pathological narcissism, negative cognitive processing bias and interpersonal conflict of 540 college students were investigated by the super brief-PNI, negative cognitive processing bias questionnaire and NRI-relationship quality version.Descriptive analysis, correlation analysis and reliability test of the questionnaires were conducted by SPSS 27.0 software.Amos 23.0 software was used for structural equation modeling, and the nonparametric percentile Bootstrap method based on deviation correction was used for intermediary effect test.Results:The scores of pathological narcissism, negative cognitive processing bias and interpersonal conflict were (3.33±0.86), (2.41±0.60) and (2.34±0.77), respectively.Pathological narcissism, negative cognitive processing bias and interpersonal conflict were significantly positively correlated ( r=0.38-0.94, all P<0.01). Negative cognitive processing bias played full mediating role in the relationship between pathological narcissism and interpersonal conflict. The model was well fitted ( χ2/ df=2.63, CFI =0.99, NFI=0.98, IFI=0.99, TLI=0.98, RMSEA=0.05). Path analysis and mediation test showed that pathological narcissism had a significant predictive effect on the total effect of interpersonal conflict among college students ( β=0.52, P<0.001). Pathological narcissism had a significant predictive effect on negative cognitive processing bias ( β=0.64, P<0.001). Negative cognitive processing bias had a significant predictive effect on interpersonal conflict ( β=0.76, P<0.001). Pathological narcissism didn’t predict the direct effect of interpersonal conflict significantly ( β=0.03, P>0.05). Conclusion:Pathological narcissism has a positive predictive effect on interpersonal conflict among college students.Negative cognitive processing bias plays a complete intermediary role between pathological narcissism and interpersonal conflict.

Objective:Revise the Chinese version of body dysmorphic disorder scale (CBDDS) and test its reliability and validity in Chinese college students.Methods:In October 2022, college students were surveyed with the body dysmorphic disorder scale (BDDS), the body image disorders scale (BIDS), the appearance anxiety scale-brief (AAS-B), the Chinese body shame scale (CBSS) and short-depression scale (SDS). Totally 59 college students (sample 1) were subjected to evaluate the popularity degree of the scale, 493 college students (sample 2) were subjected to complete item and exploratory factor analysis, 457 colleges students (sample 3) were subjected to complete the confirmatory factor analysis, totally 89 colleges students (sample 4) were subjected to complete the re-test reliability analysis.SPSS 25.0 software was used for item analysis, exploratory factor analysis, reliability analysis, Pearson correlation analysis.AMOS 24.0 software was used for confirmatory factor analysis, convergent validity analysis.Results:(1) The CBDDS was consisted of 3 dimensions including pathological beliefs, appearance anxiety and overgrooming, and the three-factor model fitted well ( χ2/ df=3.14, GFI=0.93, CFI=0.91, TLI=0.91, RMSEA=0.07). (2) The score of CBDDS was positively correlated with the score of BIDS, AAS-B, CBSS and SDS ( r=0.41-0.81, all P<0.01). In addition, the composite reliability coefficients were 0.75-0.95 and AVE coefficients were 0.51-0.56.(3) The CBDDS had good internal reliability with Cronbach's α coefficients from 0.75 to 0.94, split-half reliability coefficients from 0.65 to 0.90 and re-test reliability coefficients from 0.71 to 0.91 (all P<0.01). Conclusion:The CBDDS has acceptable reliability and validity and can be an effective scale for Chinese college students.

Objective:To offer a revised Chinese version of the object attachment questionnaire(OAQ), and to examine its reliability and validity in Chinese college students.Methods:Totally 1 350 college students were tested with the Chinese version of OAQ, Chinese version of the saving inventory-revised scale(SI-R), experiences in close relationships inventory(ECR) and emotion attachment questionnaire(EAQ). A total of 100 college students from the sample were followed to complete the Chinese version of OAQ after 4 weeks.Item analysis, correlation analysis, exploratory factor analysis and reliability test were conducted by SPSS 24.0 software, while confirmatory factor nalaysis and convergent validity were conducted by AMOS 21.0.Results:The exploratory factor analysis showed that Chinese version of OAQ included two factors and twelve items.Confirmatory factor analysis showed that the two-factor model fitted well( χ2/ df=3.76, GFI=0.93, CFI=0.90, TLI=0.87, IFI=0.90, RMSEA=0.08). The OAQ positively correlated with SI-R, ECR and EAQ ( r=0.22, 0.34, 0.63, all P<0.01, CR=0.74-0.85, P<0.01.AVE=0.29-0.39, P<0.01). The OAQ had good internal reliability with Cronbach’s α coefficients from 0.78 to 0.83, retest reliability coefficients from 0.87 to 0.97 and split-half reliability coefficients from 0.60 to 0.76(all P<0.01). Conclusion:The Chinese version of OAQ has acceptable reliability and validity.
