Objective To develop the scale to measure online intimate relationship and test its validity and reliability for college students.Methods A total of 1 105 subjects were recruited in this investigation for 6 times.Based on literatures,open-ended questionnaire investigations,semi-structured interview and experts' opinions,item analyses,exploratory factor analyses,validity and reliability analysis were conducted to develop the scale.Results The self-made scale showed a second-order structure,including intimacy,passion and commitment dimension.Confirmatory factor analysis showed that the model had good fit (χ2/df=3.47,GFI=0.92,NFI=0.90,CFI=0.92,TLI=0.90,IFI=0.92,RMSEA=0.08).The 3 dimensions had good internal reliability with Cronbach's α coefficients from 0.73 to 0.89 and retest reliability coefficients from 0.80 to 0.91.In addition,the scale had good external validity and convergent validity.ConclusionThe self-made scale has acceptable reliabilities and validities,which can be used to measure online intimate relationship for college students.

Objective:To explore the relationship among childhood psychological maltreatment,online aggressivebehavior and trait anger in college students.Methods:Totally 442 college students (226males,216 females,aged 16-25 years) were surveyed with the Psychological Maltreatment Scale (PMS),Adolescent Online Aggressive Behavior Scale (AOABS) and Trait Anger Scale (TAS).The bias-corrected percentile bootstrap method was used to analyze the mediating effect of trait anger between childhood psychological maltreatment and online aggressive behavior.Results:The scores of PMS,AOABS and TAS were positively correlated each other(r =0.44,0.37,0.48,Ps ＜0.01).The PMS scores had a significantly direct effect on the AOABS scores,its estimate was 0.27.The PMS scoreshad a significantly indirect effect on the AOABS scores through TAS scores(95％ CI:0.15-0.34).Conclusion:It suggests that the trait anger may be related to childhood psychological maltreatment and online aggressive behavior,and trait anger may play a partial mediating role between childhood psychological maltreatment and online aggressive behaviorin college students.

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 explore the mediating effects of self-focused attention between social anxiety and interpersonal needs. Methods: Totally 467 college students [159 males and 221 females, mean age (21 ±2)] were assessed with the Social Anxiety Scale (SAS), Self-Focused Attention Scale (SFAS) and Interpersonal Needs Questionnaire (INQ ). The bootstrap method was used to test the mediating effect Results: The SFAS and INQ scores were higher in female students than in males (Ps <0.01). The scores of SAS, SFAS, and INQ were positively correlated each other (r = 0.20 - 0.90, Ps < 0.01). Self-focused attention has a full mediating effect between social anxiety and interpersonal needs, and the 95％ confidence interval was (0.34, 0.59). Conclusion: It suggests that the effect of interpersonal needs on social anxiety may be achieved through self-focused attention in college students. Reducing the level of self-focused attention may be an important way to alleviate social anxiety among college students.

Objective: To explore the effect of mental health education on the problematic social media use among college students, and to provide the basis for college mental health education in colleges and universities. Methods: Problematic Social Media Use was used to select 44 college students who were randomly assigned into experimental and control group. The experimental group received psychological intervention once a week for eight weeks, and the control group did not receive any intervention. Loneliness Scale,Univesity of California of Los Angels(UCLA), Multidimensional State Boredom Scale(MSBS), Interpersonal Anxiety Scale(IAS) were administered before and after the experiment in both of the groups. Results: There was no significant differences between the experimental and the control group in total score of UCLA, MSBS, IAS and AQPMS. After intervention, prevalence of problematic mobile social media use in experimental group decreased from 100.0% to 45.8%. After intervention, significant differences in total score of UCLA, MSBS, IAS and AQPMS were observed in experimental group(P<0.05), as well as between the experimental group and the control group(P<0.05). Conclusion Mental health education can effectively reduce problematic mobile social media use, as well as negative emotions of 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.

Objective:To develop the problematic short video use scale for college students in the context of Chinese culture, and to test its reliability and validity.Methods:The questionnaire items were established based on bibliographic retrieval method, interviewing method and social investigation method.Totally 275 college students were selected as subjects for item analysis and exploratory analysis, and 642 college students were selected for confirmatory factor analysis, validity analysis and reliability analysis. One month later, 112 college students were retested and test-retest reliability data were collected. SPSS 26.0 and Mplus 8.3 softwares were used for correlation analysis, reliability and validity analysis of the questionnaires.Results:(1) The formal questionnaire contained three dimensions, 13 items in total, and the three dimensions were change of knowledge and behavior, physical discomfort and social viscosity. The internal consistency coefficients of three dimensions were 0.794, 0.820, and 0.716, respectively. The item load ranged from 0.577 to 0.805, and the variance contribution rate was 64.803%. (2) The confirmatory factor analysis results showed that χ2/ df=2.39, SRMR=0.038, RMSEA=0.047, CFI=0.970, TLI=0.963, indicated that the three-factor structure accords with the requirements of psychometrics. (3) The split-half reliability of the questionnaire was 0.885, Cronbach's α was 0.882, and the test-retest reliability after one month was 0.991. The internal consistency reliability of the total questionnaire and each dimension ranged 0.716-0.882. Conclusion:The problematic short video media use scale has good psychometric indicators and it benefits the studies of problematic short video use among Chinese college students.

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.
