The Study on Mental Health at Work: Design and sampling.

Area of Science:

• Occupational Health
• Psychosocial Epidemiology
• Workplace Mental Health Research

Background:

• The Study on Mental Health at Work (S-MGA) is the first nationwide representative survey in Germany.
• It aims to explore the complex relationships between working conditions, employee mental health, and overall functioning.
• Understanding these links is crucial for developing targeted workplace interventions.

Purpose of the Study:

• To describe the study design, sampling methodology, and data collection procedures of the S-MGA.
• To present a comprehensive summary of the socio-demographic characteristics of the study sample.
• To establish the representativeness of the S-MGA data for German employees.

Main Methods:

• A two-stage cluster sampling procedure was employed, selecting 206 municipalities and subsequently 13,590 addresses.
• Face-to-face interviews were conducted with 4511 employees aged 31-60 years, covering psychosocial work conditions, mental health, and functioning.
• Data from interviews were integrated with employment histories from register data for a holistic view.

Main Results:

• A total of 4511 interviews were successfully completed.
• Analysis indicated that older cohorts were more likely to participate.
• Slight underrepresentation was observed for individuals with unknown education, those in major cities, and non-German ethnic backgrounds.

Conclusions:

• The S-MGA sample exhibits no significant deviations from the general German working population.
• The study provides robust, representative data essential for occupational health and mental health research.
• The S-MGA is designed as a cohort study with plans for a follow-up survey in five years to track changes over time.
