(1) To estimate the pooled prevalence of psychological symptoms in Chinese migrant workers (CMWs), as measured using the Symptom Checklist-90-R (SCL-90-R) in observational studies conducted in China, and (2) to explore the potential variables associated with the SCL-90-R Global Severity Index (GSI), the overall mental health indicator of CMWs.
We performed a comprehensive literature search of the major English and Chinese databases (to June 2012). Cross-sectional surveys and case-control studies of CMWs (and controls where appropriate) that reported at least one subscale score of the SCL-90-R were included. Multilevel meta-analysis was used to pool the symptom scores of cross-sectional surveys and mean differences of symptom scores ("Cohen's d" values) between CMWs and controls of case-control studies. Multilevel meta-analysis with ecological- or study-level covariates was used to explore the associations between variables and SCL-90-R GSI score.
The search yielded 48 cross-sectional surveys (comprising 42,813 CMWs) and seven surveys that included control samples. The pooled psychological symptom scores (95% confidence interval) of CMWs were statistically higher than those of norms from Chinese general population on all scales of SCL-90-R, except for obsessive-compulsive subscale in study quality subgroup analysis. CMWs also scored statistically higher than those of urban counterpart controls on all scales of SCL-90-R. Multilevel regression meta-analysis model revealed that four covariates that accounted for 33.9% of SCL-90-R GSI heterogeneity across all surveys, including: "mean age of study sample," "geographic area," "per capita GDP," and "statutory minimum monthly wage" of study site in implementation year.
CMWs have more severe psychological symptoms than the general population, and thus, appear to experience higher level of psychological distress. Macro-economic factors may have impact on the overall mental health of CMWs, but the factors that contribute to mental health and mental distress among CMWs remain to be explored and understood.
（1）使用症状自评量表-90 项修订版（SCL-90-R）评估在中国进行的观察性研究中中国移民工人（CMW）的心理症状总患病率，以及（2）探讨与 SCL-90-R 总体严重指数（GSI）相关的潜在变量，即 CMW 的整体心理健康指标。
我们对主要的英文和中文数据库进行了全面的文献检索（截至 2012 年 6 月）。纳入的研究为报告了 SCL-90-R 至少一个分量表评分的 CMW（和适当对照者）的横断面调查和病例对照研究。使用多级荟萃分析对横断面调查的症状评分进行合并，对病例对照研究中 CMW 与对照者的症状评分差值（“Cohen's d”值）进行合并。使用具有生态或研究水平协变量的多级荟萃分析，探讨变量与 SCL-90-R GSI 评分之间的关联。
检索共获得 48 项横断面调查（包含 42813 名 CMW）和 7 项包含对照样本的调查。除了研究质量亚组分析中研究样本强迫症分量表外，CMW 的 SCL-90-R 所有分量表的总分均显著高于中国一般人群的常模。CMW 在 SCL-90-R 的所有分量表上的得分也显著高于城市对照组。多级回归荟萃分析模型显示，四个协变量解释了所有研究中 SCL-90-R GSI 异质性的 33.9%，包括：“研究样本的平均年龄”、“地理区域”、“人均 GDP”和“实施年份研究地点的法定最低工资”。
CMW 的心理症状比一般人群更严重，因此，他们似乎经历了更高水平的心理困扰。宏观经济因素可能对 CMW 的整体心理健康有影响，但 CMW 心理健康和心理困扰的相关因素仍有待探索和理解。
