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 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.
