Analysis on components of attentional bias on anger and disgust emotional faces in college students with social anxiety disorders / 中华行为医学与脑科学杂志

Objective To analyze the components of attentional bias on anger and disgust emotional faces in college students with social anxiety disorder.Methods DSM-V was used for clinical diagnosis after the initial screening with Interaction Anxiousness Scale.The subjects meet the inclusion criteria were divided into social anxiety disorder group (SAD group) and healthy control group (HC group).Koster's improved dot-probe paradigm was used in a 2 (group:SAD group,HC group) ×2 (emotion categories:anger,disgust)mixed-design experiment,and the different characteristics of attentional bias between the two groups on different emotional faces were compared.Results In SAD group,under the condition of angry faces,the response times to the probe targets with the same or different positions from the negative faces were (369.7±53.0)ms and (447.2±54.3) ms,while the response times were (429.6±70.2) ms and (444.2±55.8) ms under the condition of disgust faces,and the SAD group showed attentional bias towards both anger and disgust faces (t =24.15 and 2.45,P＜0.05).Under the condition of anger faces,the response time of HC group to the consistent and inconsistent position of probe target were (466.9±40.0) ms and (483.8±43.8) ms,and the HC group had an attentional bias towards anger faces(t=6.58,P＜0.05).The response time under disgust faces was (493.8±43.6)ms and (498.0±46.7)ms in HC group,and did not show an attentional bias towards disgust(t=1.65,P=0.108).The scores of attentional orientation to anger faces in SAD group were significantly higher than those in the HC group(F=19.26,P＜0.001),but there was no significant difference between the two groups towards disgust faces (F=0.02,P=0.897).Compared with disgust faces,the attentional orientation to anger faces was faster in both HC and SAD groups (F=101.66 and 8.00,P＜0.05).Compared with the HC group,the SAD group had an impaired attentional disengagement from anger faces(F=8.66,P=0.004).Conclusion The students with social anxiety disorder have attentional bias towards both anger and disgust facial expressions,which manifested as facilitated attentional orientation and impaired attentional disengagement to anger faces.

The mediating role of attentional control between negative automatic thoughts and social anxiety among medical freshmen / 中华行为医学与脑科学杂志

Objective To explore the mediating effect of attentional control between negative automatic thoughts and social anxiety.methods A total of 1 504 college freshmen of medical university were surveyed with the Interaction Anxiety Scale (IAS),the Automatic Thoughts questionnaire (ATQ) and the Attentional Control Scale (ACS).Result sThe scores of IAS,ACS and ATQ of medical freshmen were (39.36±8.15),(53.50±7.48) and (48.93±19.72) respectively.Correlation analysis showed that ATQ total score was significantly positively correlated with IAS total score(r=0.313,P<0.01),ATQ total score was significantly negatively correlated with ACS total score(r=-0.275,P<0.01),and ACS score was significantly negatively correlated with IAS total score(r=-0.455,P<0.01).Mediating effect analysis showed that attentional control partly-mediated the relationship between negative automatic thoughts and social anxiety among medical freshmen (x2/df=1.650,GFI=0.998,AGFI=0.993,RMSEA=0.021),and accounted for 50.8% of the mediating effect.Conclusion Negative automatic thoughts is an important factor which plays direct and indirect roles in social anxiety.Attentional control is the intermediate link between negative automatic thoughts and social anxiety.

Relation between sex role and social anxiety and the mediating effect of self-acceptance study in college students / 中国心理卫生杂志

Objective:To explore the relationship between social anxiety and sex role in college students,and to analyze the mediating effect of self-acceptance between them.Methods:Data came from a sample of 2000 col-lege students in Daqing,who were selected by stratified random cluster sampling method according to the constitu-ent ratio of the college students.We used the Interaction Anxiety Scale (IAS)to assess subjective experience of so-cial anxiety,Bem Sex-Role Inventory (BSRI)to evaluate sex-role classification and Self-Acceptance Questionnaire (SAQ)to measure characteristics of self-acceptance.Results:In the college,the distribution of sex-role classifica-tion were androgynous 656 (34.9%),undifferentiated 650 (34.6%),masculine 287 (15.3%),feminine 284 (15.1%).The differences of gender in scores of IAS and SAQ were not significant (Ps >0.05),but there were significant differences among sex roles (P <0.001).IAS scores of feminine were significantly higher than the oth-ers,and the scores of androgyny and masculine were both lower than the other two significantly.SAQ scores offeminine and undifferentiated were both significantly lower than the other two respectively (Ps <0.05).By Boot-strap test,masculine,undifferentiated and feminine (vs.androgynous)could mediate IAS through self-acceptance, the mediating effects were 0.76 (95%CI:0.09 -1.42),4.14 (95%CI:3.43 -4.93),and 4.03 (95%CI:3.47 -4.64) respectively.There was a mediating effect.Both undifferentiated (vs.androgynous ) and feminine (vs.androgynous)directly influenced IAS significantly (Ps <0.05).Conclusion:Social anxiety may be related to sex role but not gender,social anxiety level of feminine students is higher,the sex-role types could influence social anxiety through self-concept indirectly.

The prevalence rate and growth environmental factors of social anxiety disorder among Daqing college students / 中华行为医学与脑科学杂志

Objective To know the point prevalence rate of social anxiety disorder(SAD) in Daqing University,and explore the influence factors about growth environment.Methods Data came from a large representative sample of 1878 university students,who were selected by stratified random cluster sampling methods according to the constituent ratio of students.They finished general situation questionnaire,interaction anxiety scale (IAS),adolescent self-rating life events check list(ASLEC),Egma Minnen av Bardndosnauppforstran(EMBU) respectively.According to the score of IAS,they were divided into 3 groups of high,mid and low.And then all of the high group,the 50％ and 10％ randomly of the mid and the low group respectively accepted the face-to-face interviews with 6 trained psychiatrists referred to SCID-I/P.Results Among 1878 Daqing university students,191 of them were diagnosed as SAD,with a point prevalence rate of 8.89％.The rate of rural students was higher than that in urban students(12.3％ vs.8.5％,x2 =7.966,P=0.017),and the rate of non-only child was higher than only child (12.0％ vs.9.1％,x2 =4.055,P=0.044).There were significant differences between SAD and No-SAD on many factors of ASLEC and EMBU.Logistic regression analysis showed that study stress in ASLEC(B=0.206),father's warm (B =-0.070),father's overprotection (B =0.286),mother's punishment (B =0.159),only child or not (B =-0.685) entered into regression equation.Conclusion The point prevalence rate of SAD in Daqing university students is 8.89％ and influenced by several growth environmental factors.Only child or not,father's warm,father's overprotection,mother's punishment,study stress in ASLEC can forecast SAD occurrence.

Objective To explore the relative contribution on predictive factors of internet addiction among junior high school students in Daqing city,and provide basis for targeted intervention on internet addiction.Methods By delaminating grouping method, based on a sample of 646 were surveyed with Internet Addiction Impairment Index and other mental scales. Through dominance analysis, study the relative contribution of various predictive factors of internet addiction. Results The correlation coefficients of life events, social anxiety, depression and positive coping with internet addiction were respectively 0.39, 0.15, 0.12 and 0.09(P＜0.05). Hierarchical regression showed that the total variance of demography in predicting internet addiction was 15%;the total variance of life events, social support, coping styles and emotion variables in predicting internet addiction was 23%. After the variables of demography were controlled, the best predictors for internet addiction were life events,social anxiety, negative coping and objective support, and these four variables explained 18.5% of the total variance of intemet addiction. Dominance analysis indicated that for the regression equation in predicting internet addiction, life events contributed 84. 52%, social anxiety contributed 8. 21% and negative coping contributed 4.72%, objective support contributed 2.54% of the predicted variance. Conclusion Internet addiction should be taking targeted preventive interventions based on the specific reasons.
