Objective:To test the validity and reliability of the University of California at Los Angeles Posttraumatic Stress Disorder Reaction Index for DSM-Ⅳ (Revision 1,Children version) (UCLA PTSD-RI) in Chinese Children after flood.Methods:On the principle of convenient sampling,the students were chosen from 6 schools in Liaoning Province where was hit by flood.Totally 1593 students [aged 8-16 years,average (11 ± 2) years of age]completed the UCLA PTSD-RI.They were randomly divided into two groups for exploratory factor analysis (n =796) and confirmatory factor analysis (n =797) respectively.The 21-item Depression Anxiety Stress Scale(DASS-21) were used to evaluate the criterion validity.Results:The result of exploratory factor analysis indicated UCLA PTSD-RI consisted of 3 factors,accounting for 50％ of the total variance.The confirmatory factor analysis identified that a three-factor model fit well (x2/df=3.87,GFI =0.93,RFI =0.96,CFI =097,NNFI =0.97,IFI =0.97,RM-SEA =0.06).The scores of UCLA PTSD-RI subscales were positively correlated with the scores of DASS-21 subscales (r =0.52-0.70,Ps ＜ 0.001).The Cronbach's a coefficient and the split-half reliability coefficient of UCLA PTSD-RI were 0.90 and 0.87,respectively.Conclusion:The Chinese Version of the UCLA PTSD Reaction Index for DSM-Ⅳ (Revision 1,Children version) could be an effective instrument for assessing and diagnosing PTSD of Chinese children after disasters.

Objective To compare the identifiability for depressive symptoms using different instruments while interviewing with different respondents in suicide prevention research in China. Methods One hundred and fifty-one suicide death cases (suicide group) and one hundred and twenty suicide attempt cases (attempt group) were recruited. For each identified cases, one family member proxy respondent, and another associate proxy respondent (friend or neighbor) and suicide attempter (only for attempt group) were interviewed separately by qualified psychiatrists. The Di-agnostic Screening Instrument for Depression (DSID) and the Structured Clinical Interview for DSM-Ⅳ Axis Ⅰ Disorders (SCID-Ⅰ) were administered to each respondent to identify the depressive symptoms based on diagnostic criteria for major depressive episode in DSM-Ⅳ. Data collected from family members and associate respondents were merged as proxy data. The concordances of the DSID and SCID-Ⅰfor identifying depressive symptoms, meeting for criteria of Major Depressive Episode (MDE) and Mild and Major Depressive Episode (MMDE), were calculated based on different respondents' data. The prevalence of depressive symptoms, MDE and MMDE, were compared among merged proxy data, family member respondent's data, and associate respondent's data in suicide group and attempt group, and between self-respondent's data and merged proxy data in suicide attempt group. Results In suicide group, based on merged proxy data, the prevalence of MDE was 41.1%(62 cases) for DSID and 41.7%(63 cases) for SCID-Ⅰ, and the Kappa coeffi-cient was 0.77. Based on suicide attempters' self-raported data, the prevalence of MDE was 23.7% (27 cases) and 22.0% (24 cases) for DSID and SCID-Ⅰ respectively, with a Kappa of 0.74. Based on merged proxy report in attempt group, 16 (13.3%) and 15 (12.5%) cases were met for criteria of MDE (Kappa=0.89), using the 2 instruments. In both of the suicide and attempt groups, the merged proxy data got higher prevalence of depressive symptoms, MDE and MMDE than that only based on family respondent's data or associate's respondent's data using both of the 2 instruments (all P<0.05). Compared with merged proxy data, attempters' self-reported data got higher prevalence of MMD and MMDE using both of the 2 instruments (all P<0.05). Conclusions Based on same respondent's data, SCID-Ⅰ performs as well as DSID in identifying depressive symptoms. Collecting data from 2 respondents would get higher prevalence of MDE or MMDE than only from one family member or one associate. In attempt group, the prevalence of MDE or MMDE based on merged proxy data were lower than that based on attempters' self-reported data.

Objective: To evaluate the false positive rate and false negative rate of the Chinese version of the 12-item General Health Questionnaire (GHQ-12) and the related factors in the epidemiological survey of mental ill-nesses in Zhejiang Province. Method: A total of 15000 subjects were randomly selected from the province-wide using multi-stage stratified cluster randomization. Analyses for this paper were made in the quality control sample,10% of the total 15000 subjects (1510 subjects) in which the Chinese version of Structured Clinical Interview for DSM-Ⅳ Axis Ⅰ Disorders (SCID) was used as a golden criterion, and a cutoff score of the GHQ-12 was set to ≥ 3 to define GHQ-12 cases. Results: Totally 1449 subjects (96.0%) completed both the GHQ-12 and the SCID. Adjusted for sampling effects, the false positive and negative rates of the GHQ-12 were respective 14.6% and7.8%. Adjusted for other considered correlates and sampling effects, the adjusted odds ratios (AORs) of GHQ-12 false positive with living in less economically developed urban areas (urban type Ⅱ), with self-reportedly poor physical health, with having ever sought help because of mental problems and with being currently married/co-habited were respective 2.23 (95% CI:1.24～4.01), 2.36(1.36～4.10), 1.53 (1.10～2.14) and 0.51 (0.30～0.86) while AORs of GHQ-12 false negative with being aged 35～49 year group and living in less econom-ically developed rural areas (rural type Ⅲ) were respective 2.59 (1.18～5.67) and 2.72 (1.21～6.14). Conclusion:Factors related to the GHQ-12 false positive and negative are different. The cutoff scores of the GHQ-12 should be used based on the characteristics of subjects during identifying or screening mental illnesses.

Objective To assess the prevalence of Personality Diagnostic Questionnaire (PDQ)personality deviations in patients referred for functional dyspepsia (FD) with reliable and universal psychological measures, and to explore the relationship between co-occurring PDQ-personality deviations and functional dyspepsia. Methods The sample comprised 246 patients referred for functional dyspepsia. Four groups were divided according to their patterns of gastrointestinal symptoms: the FD group, FD with refluxlike symptom group(FD + RS group), FD with irritable bowel syndrome group( FD + IBS group), and FD with reflux-like symptom and irritable bowel syndrome group ( FD + RS + IBS group). Participants were assessed with the Personality Diagnostic Questionnaire for DSM-Ⅳ ( PDQ-4 ) to evaluate the presence of personality deviations. Results Overall 65% patients scored positive for any personality deviation, male and female alike. Cluster C (anxious/fearful) personality was most commonly found in FD patients (142 patients, 57.7% ). The FD + IBS group and the FD + RS +IBS group had significantly higher total PDQ scores than the FD group (23.39 ± 8. 77 and 24. 22 ± 10. 97 vs 18.98 ± 11.88, P ＜ 0. 05, respectively),indicating that FD patients with greater level of personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract. Reflux-like symptom without actual pathological acid regurgitation indicated cluster A (odd/eccentric) personality deviations. Conclusions The current study shows personality deviations are common in patients referred for functional dyspepsia. Negative emotions,maladaptive coping, and lack of social support, may strongly influence their healthcare-seeking behavior.There is no single personality type specific for some kind of gastrointestinal symptom. But FD patients with personality deviations tend to report other symptoms involving the esophagus and lower gastrointestinal tract.

Objective:To explore the clinical features of subtyp es of ADHD in DSM-Ⅳ.Method:126 children fulfilled ADHD criteria of D S M-Ⅳ were further divided into 3 subtypes:predominantly inattentive(PI,61 cases) , predominantly hyperactive-impulsive(HI,9 cases)and combined type(CT,56 cases).C om orbid mental disorders were compared among the three groups.Parents and teacher s of children in each group completed CBCL(child behavior checklist)and TRF(teach er's report form).CWISC(Wechsler intelligence scale for children,Chinese versio n )and attention tests were also applied in each group.Results:Childr e n in CT group had more conduct disorder,more externalizing,delinquent and aggres sive behaviors rating by parents and teachers,and more inattentive than children in PI group.School performance of children in PI group was better than that of the other two groups evaluated by teachers.Conclusion:ADHD CT subty pe had highest rate of comorbid conduct disorder.They have more externalizing b ehavior,more academic problems and more inattentive.This subtype may be the mos t impaired subtype.
