Objective:To analyze suicide methods and demographic characteristics of attempted suicide pa-tients in Baise City,Guangxi and to provide the basis for suicide intervention.Methods:A retrospective analysis method was conducted on the case data of attempted suicide patients treated in the emergency departments of 14 general hospitals in Baise City from 2018 to 2021.The situation of attempted suicide patients was recorded using the suicide patient information collection forms.Results:Among the 2 529 attempted suicide patients,1 636 committed-suicide by taking pesticides,557 used therapeutic drugs,112 used rodenticides,and 53 used carbonmonoxide(CO).The proportion of male and farmer suicides by taking pesticides was higher,and the proportion of female and non-farmer suicides by taking therapeutic drugs was higher.Multivariate analysis showed that the proportion of patients aged 45-60 years old patients who took pesticide was higher(OR=3.18),while the proportion of patients aged 45～60 who took therapeutic drugs was lower(OR=0.19).The proportion of suicides taking pesticides and using carbon monoxide significantly decreased in 2020(OR=0.56)and 2021(OR=0.52),while the proportion of sui-cides taking therapeutic drugs significantly increased in 2020(OR=2.04)and 2021(OR=3.18).Conclusion:Proportion of attempted suicide by taking pesticides is the most common method of suicide among residents in Baise City,with males,farmers,and middle-aged groups being the most affected.The proportion of attempted suicide by taking medication has significantly increased,with a higher incidence among women.

Objective:To examine the roles played by peer attachment and cognitive fusion in the association between negative life events and depression,as well as the differences in these relationships of variables among pri-mary and secondary school students.Methods:A total of 2 767 students(1 950 elementary school students and 817 middle school students)were selected.The Adolescent Life Events Scale,the Experiences in Close Relationships-Relationship Structures Questionnaire,the Cognitive Fusion Questionnaire,and the Patient Health Questionnaire were used to measure negative life events,peer attachment,cognitive fusion,and depression,respectively.Results:Negative life events,peer attachment,cognitive fusion and depression were positively correlated with each other(r=0.36-0.75,Ps＜0.001);the mediation effects of peer attachment and cognitive fusion and their chain mediation effects were 0.04,0.30,and 0.04,respectively,accounting for 6.7％,50％,and 6.7％of the total effect.There were significant differences in the chain mediation model between primary and secondary school students(△x2=47.12,△df=6,P＜0.001),and significant gender differences in the chain mediation effect among primary school students(△x2=43.72,△df=6,P＜0.001).Conclusion:Negative life events influence depression in primary and secondary school students both directly and indirectly through peer attachment and cognitive fusion.Negative life e-vents have greater impact on primary school students'(particularly girls)peer attachment.Peer attachment has grea-ter impact on secondary school students' cognitive fusion.Cognitive fusion has greater impact on primary school students' depression.Peer attachment has greater impact on primary school boys' depression.

Objective:To investigate the association between prenatal environmental factors and attention defi-cit hyperactivity disorder(ADHD)and its symptom severity in children.Methods:Based on the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)diagnosis criteria,1 156 children with ADHD and 289 normal control children were included in this study.ADHD diagnoses were established using the Clinical Diag-nostic Interview Scale,core symptoms were assessed with the ADHD Rating Scale,and information on prenatal ex-posures were collected via self-developed questionnaires.Results:Maternal stress during pregnancy was associated with increased risk factor of ADHD in children(OR=1.22,P＜0.01).Among children with ADHD,preconception paternal alcohol consumption was positively associated with hyperactivity/impulsivity symptoms(β=0.08,P＜0.05),and maternal smoking during pregnancy was positively associated with total symptoms(β=0.07-0.09,P＜0.05).Conclusion:Maternal stress during pregnancy may increase the risk factor of ADHD in children.Both pre-conception paternal alcohol consumption and maternal smoking during pregnancy may be associated with increased ADHD symptom severity in children.

Objective:To investigate the relationship between empathy and meaning in life among medical students,and explore the mediating role of altruistic behavior.Methods:A total of 581 medical students were recrui-ted.They were assessed with the Interpersonal Reactivity Index-C(IRI-C),Altruistic Behavior Questionnaire of College Students(ABQ-CS),and Quadripartite Existential Meaning Scale(QEMS).The bootstrap method was used to test the hypothesized mediating effect.Results:The scores of IRI-C were positively correlated with the scores of ABQ-CS and QEMS(r=0.45,0.21,Ps＜0.001).The scores of ABQ-CS were positively correlated with the QEMS scores(r=0.46,P＜0.001).Altruism was a complete mediator between empathy and meaning in life,the indirect effect was 0.20(95％CI:0.15-0.26).Conclusion:This study reveals the underlying connections a-mong altruistic behavior,empathy,and meaning in life among medical students,suggesting that interventions targe-ting empathy and altruistic behavior may enhance their meaning in life.

Objective:To understand the post-traumatic growth status and related factors of patients with liver cancer undergoing interventional therapy.Methods:A total of 160 patients with liver cancer receiving interventional therapy in a third-class first-class hospital in Xuzhou were assessed using the Self-designed General Information Questionnaire,Post Traumatic Growth Inventory(PTGI),Medical Coping Modes Questionnaire(MCMQ)and Quality of Life for Liver Cancer(QOL-LC).Results:The PTGI total score was(53.8±10.1).Multiple regression analysis showed that the average monthly family income(β=0.11),face-to-face scores(β=0.28)and the total QOL-LC scores(β=0.16)were positively correlated with the PTGI scores,whereas advanced disease stages(β=-0.14),number of interventional therapy sessions(β=-0.06)and avoidance scores(β=-0.27)were negative-ly correlated with PTGI scores.Conclusion:The post-traumatic growth of patients with liver cancer treated by inter-ventional therapy is at a moderate-to-low level.Post-traumatic growth is related to family income per capita,disease stages,times of interventional therapy,medical coping style and quality of life.

Objective:To report the therapeutic effectiveness of Mindfulness-Based Cognitive Therapy(MBCT)for one outpatient with depression.Methods:A pre-and post-intervention design was used to evaluate a 10-week online MBCT intervention for case W.The Symptom Check List-90(SCL-90),Defense Style Question-naire(DSQ),Mindful Attention Awareness Scale(MAAS),Self-Acceptance Questionnaire(SAQ),and NEO-Five Factor Inventory(NEO-FFI)were conducted one week before MBCT(baseline),five weeks during MBCT,one week after the end of MBCT,and two years after the end of MBCT.A semi-structured interview was conducted with W five months after the end of MBCT.Results:Quantitative results showed that no matter one week or 2 years after the end of MBCT,W's depression,anxiety,immature defense mechanisms,mindfulness levels,self-acceptance levels,and extroversion/agreeableness all showed reliable improvement compared to baseline(|RCI|＞1.96).Qualitative analysis showed that in W's narrative,psychiatric drugs,enhancing awareness,avoiding thinking biases,promoting self-acceptance and care,and stable treatment alliances were the factors that W could benefit from MBCT.Conclusion:Online MBCT could effectively improve the symptoms and psychological function of this out-patient with depression.

Objective:To examine the attentional processing of verbal emotional information in college students with subclinical depression.Methods:Fifty college students were recruited(24 with subclinical depression group and 26 in the control group)were recruited from a university in Liaoning Province to investigate the atten-tional bias of subclinically depressed college students towards verbal emotional information(experiment 1).In addi-tion,48 college students(20 with subclinical depression and 28 in the control group)were recruited to investigate the attention disengagement of subclinically depressed college students from verbal emotional information(experi-ment 2).In experiment 1,two groups passively viewed words and recorded the eye movement data of emotional words.In experiment 2,two groups were asked to watch the emotional word-neutral word pair.When color borders were presented around neutral words,the attention disengagement latency that was the time taken by the eye saccade from emotional words to neutral words was recorded.Results:The results of experiment 1 showed that the total fix-ation duration of negative words in the subclinical depression group was longer than that in the control group(P＜0.01).The results of experiment 2 showed that attention disengagement latency of negative words in the subclinical depression group was longer than that in the control group(P＜0.05).Conclusion:College students with subclini-cal depression exhibit attentional bias towards negative verbal information and difficulties in attentional disengage-ment.

Objective:To explore the relationship between latent categories of meaning in life and aggression among male prisoners,and analyze the mediating role of negative emotions.Methods:Five hundred and thirty-seven male prisoners were selected and assessed with the Meaning in Life Questionnaire(MLQ),Chinese version of Buss& Perry Aggression Questionnaire(AQ-CV),and Depression-Anxiety-Stress Scale(DASS-21).Latent profile anal-ysis was used to explore the potential categories of meaning in life,as well as to test the mediating role of negative emotions using relative mediation analysis.Results:Four categories of meaning in life were identified,namely nega-tive meaning in life(20.3％),low experiential-high seeking(28.3％),high experiential-low seeking(16.0％),and positive meaning in life(35.4％)types were present among the prisoners.The scores of aggression decreased sequentially from the negative meaning in life type to the low experiential-high seeking type,and then to the high experiential-low seeking type(Ps＜0.05).Compared to the negative meaning in life type,the mediating role of the high experiential-low seeking type(β=-0.59,95％CI=-0.75--0.43)and the positive meaning in life type in aggression through negative emotions was statistically significant(β=-0.56,95％CI=-0.71--0.42).Conclusion:The study suggests that male prisoners with a higher meaning in life tend to exhibit lower aggression,and that individuals with a higher experiential meaning in life have lower aggression through diminished negative e-motions,compared to those with a negative meaning in life type.

Objective:To develop and validate the Online Fraud Susceptibility Scale(OFSS).Methods:The construct of online fraud susceptibility was defined through qualitative interviews(n=14)and expert evaluations(n=6).Based on prior literature,an initial item pool was generated.A sample of 805 adults completed the preliminary scale for item analysis and exploratory factor analysis(EFA).Another sample of 491 adults completed the formal scale for confirmatory factor analysis(CFA),criterion validity,and internal consistency analysis.Of these,233 par-ticipants were retested after four months.The Vulnerability to Fraud Questionnaire(VFQ)and the Susceptibility to Persuasion-Ⅱ Scale(StP-Ⅱ)were used as criterion measures.Results:The 25-item OFSS consisted of 5 factors,na-rely monetary motivation,heuristic processing,financial risk-seeking,anti-fraud knowledge,and susceptibility to so-cial influence,explaining 51.94％of the total variance.The factor loadings ranged from 0.52 to 0.80.The 5-factor model showed an acceptable structural fit(x2/df=2.39,CFI=0.86,TLI=0.84,CFI=0.86,RMSEA=0.05).The OFSS scores were positively correlated with the scores of VFQ and StP-Ⅱ(r=0.51,0.47,Ps＜0.001).The inter-nal consistency reliabilities of the total score and 5 factors ranged from 0.64 to 0.80,and the retest reliabilities(ICC)of the total score and 5 factors ranged from 0.53 to 0.78.Conclusion:The Online Fraud Susceptibility Scale demonstrates satisfactory psychometric properties providing a practical tool to assess the vulnerability to online fraud.

Objective:To examine the information processing patterns of college students with high and low procrastination in intertemporal decision-making.Methods:A total of 29 high procrastination college students[Irra-tional Procrastination Scale(IPS)score＞27]and 29 low procrastination college students(IPS score≤27)were recruitted.A 2(group:high/low procrastination)×2(amount:￥100,￥1 000)×5(delay:10/30/90/180/360 days)mixed experimental design was employed.Behavioral measures(delay discounting rates,Payne index)and eye-tracking measures(option/dimension fixation time ratios)were collected.Results:The delay discounting rate had the main effects of group,amount and delay(F=6.62,25.38,121.31,Ps＜0.05).The delay discounting rates were higher in the high procrastination group than in the low procrastination group.The delay discounting rates were higher for a amount of 1 000 yuan than 100 yuan.The delay discounting rate was the highest when the delay was 10 days.The option fixation time ratios were higher in the high procrastination group than in the low procrastination group(P＜0.01),and there were interaction effects between group and amount and between group and delay(F=5.67,2.52,Ps＜0.05).The dimension fixation time ratios were lower for a amount of 1 000 yuan than 100 yuan(P＜0.01).Conclusion:College students with high procrastination exhibit a higher delay discounting rate and stronger attentional bias toward immediate options during intertemporal decision-making.However,both groups pri-oritized the monetary dimension in their information processing strategies.
