ABSTRACT
To investigate the mental health status of the floating population in Chengdu and explore its influencing factors. A questionnaire-based survey was conducted on non-Chengdu household workers over 16 years old in four directions(east,south,west,and north)of Chengdu from June 2017 to June 2018 to collect their social demographic characteristics and mental health status information through respondent driven sampling method.The 12-item general health questionnaire(GHQ-12) was used to assess the mental health status of the respondents,and a multivariate logistic regression model was used to analyze the influencing factors of mental health. The average score of GHQ-12 was(1.09±1.61)and the detection rate of mental problems was 7.11%.The main mental problems were anxiety and nervousness.Multivariate unconditional logistic regression analysis showed that over 55 years old(=0.425,95%=0.213-0.847),junior middle school education(=0.541,95%=0.356-0.824),length of residence ≥5 years(5-9 years:=0.603,95%=0.394-0.923;≥10 years:=0.534,95%=0.346-0.823),annual income ≥18 000 yuan(18 000-35 999 yuan:=0.524,95%=0.328-0.836;36 000-59 999 yuan:=0.327,95%=0.190-0.565;≥60 000 yuan: =0.356,95%=0.192-0.662),and a good relationship with employers(=0.519,95%=0.363-0.742)were the protective factors for the mental health.Divorce/widowhood(=2.351,95%=1.341-4.124),plan to return hometown after 5 years(=1.805,95%=1.084-3.006)and not yet consideration of leaving Chengdu(=1.844,95%=1.269-2.681)were the risk factors. The mental health of the floating population in Chengdu is generally good.However,floating individuals with poor marital status and/or poor sense of belonging to Chengdu are at higher risk of mental problems.The local government should formulate and improve the policies and measures related to social welfare and public services for the floating population and try to enhance their urban integration and sense of belonging,thus improving their mental health.

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.
