The Study on Mental Health at Work (S-MGA) generates the first nationwide representative survey enabling the exploration of the relationship between working conditions, mental health and functioning. This paper describes the study design, sampling procedures and data collection, and presents a summary of the sample characteristics.
S-MGA is a representative study of German employees aged 31-60 years subject to social security contributions. The sample was drawn from the employment register based on a two-stage cluster sampling procedure. Firstly, 206 municipalities were randomly selected from a pool of 12,227 municipalities in Germany. Secondly, 13,590 addresses were drawn from the selected municipalities for the purpose of conducting 4500 face-to-face interviews. The questionnaire covers psychosocial working and employment conditions, measures of mental health, work ability and functioning. Data from personal interviews were combined with employment histories from register data. Descriptive statistics of socio-demographic characteristics and logistic regressions analyses were used for comparing population, gross sample and respondents.
In total, 4511 face-to-face interviews were conducted. A test for sampling bias revealed that individuals in older cohorts participated more often, while individuals with an unknown educational level, residing in major cities or with a non-German ethnic background were slightly underrepresented.
There is no indication of major deviations in characteristics between the basic population and the sample of respondents. Hence, S-MGA provides representative data for research on work and health, designed as a cohort study with plans to rerun the survey 5 years after the first assessment.
工作场所心理健康研究（S-MGA）开展了首次全国代表性调查，以探究工作条件、心理健康与功能之间的关系。本文描述了研究设计、抽样程序和数据收集情况，并呈现了样本特征总结。
S-MGA是一项针对31至60岁缴纳社会保险的德国员工的代表性研究。样本基于两阶段整群抽样程序从就业登记册中抽取。首先，从德国12227个城市中随机选取206个城市。其次，从选定城市中抽取13590个地址，用于进行4500次面对面访谈。问卷涵盖心理社会工作和就业条件、心理健康、工作能力和功能的测量指标。个人访谈数据与登记数据中的就业历史相结合。使用社会人口特征描述性统计和逻辑回归分析来比较总体、总样本和受访者。
总共进行了4511次面对面访谈。抽样偏差测试显示，年龄较大队列中的个体参与度更高，而教育程度未知、居住在大城市或具有非德国族裔背景的个体代表性略低。
没有迹象表明基本总体与受访者样本在特征上存在重大偏差。因此，S-MGA为工作与健康研究提供了代表性数据，该研究设计为队列研究，并计划在首次评估5年后重新进行调查。
