Risk assessment of mental stress – structured, legally compliant in accordance with ISO 45003, with measurable results

As an effective instrument of relationship prevention – not as a mandatory document for the personnel file.

The risk assessment of mental stress has been required by law since 2013 – and yet in many companies it is still only treated as a compulsory exercise. The result is reports that disappear into folders and measures that no one keeps track of. We work differently. Our process starts with a scientifically based questionnaire, translates the results into structured workshops and puts structural issues where they belong – in a working group that is responsible for organizational change. The goal is not documentation. The goal is to measurably improve working conditions.

The legal framework in brief

The legal and technical framework can be summarized in four points:

  • § Section 5 paragraph 3 number 6 ArbSchG obliges the employer to take mental stress at the workplace into account in the risk assessment. This obligation applies regardless of company size or sector.
  • § Section 6 ArbSchG prescribes the documentation of the assessment, the defined measures and the effectiveness check. Without documentation, the assessment is deemed not to have been carried out.
  • The GDA recommendations(4th edition 2022, updated January 2026) specify the process along six design areas and seven procedural steps. They are the authoritative technical frame of reference for employers, supervisory authorities and accident insurance institutions throughout Germany.
  • The works or staff council has co-determination rights in the organization and implementation of the assessment in accordance with § 87 BetrVG or the corresponding staff representation laws.

The legal situation sets the framework, but leaves methodological leeway. Anyone who wants to use the risk assessment as a data basis for effective OHM can find a detailed classification in the blog article “The limits of the GDA guideline – and what ISO 45003 adds“.


The Eudemos process in seven phases

Our process follows the seven-stage model of the Joint German Occupational Health and Safety Strategy and thus fully complies with the legal requirements. At the same time, our methods are based on ISO 45003the international standard for the management of psychosocial risks, which consistently anchors mental health as a control parameter in the management system. The actual quality is determined by how the individual phases are structured in terms of content – and this is precisely where the differences lie between a compulsory exercise and an assessment that actually leads to change.

The Eudemos GBU.Q – questionnaire for psychological risk assessment

Complete coverage of all six GDA design areas, expanded to include the stress dimensions of modern work. Compatible with ISO 45003:2021. Scientifically sound, proven in practice, ready for immediate use.

The Eudemos GBU.Q is available for technical insight and internal evaluation. The productive use including evaluation, factor logic and derivation of measures is carried out by AGIONT or with the support of Eudemos. Publisher: Eudemos Beratungsgesellschaft GmbH, Berlin / Eudemos ApS, Copenhagen.

The Eudemos GBU.Q is the questionnaire that we have been using for years to carry out risk assessments of mental stress in companies, administrations and public institutions – from local authorities to magistrates and police authorities. It exceeds the requirements of § 5 paragraph 3 number 6 ArbSchG and fully reflects the GDA work program Psyche (4th edition 2022, update 2026).

With version 2026.1, we have expanded the questionnaire to include the stress dimensions that are systematically underrepresented in traditional GBU practice: digital communication intensification, psychological safety based on Edmondson, availability outside working hours, mobile work, leadership experience from the perspective of managers, cultural and trust factors and boundary violations in the workplace.

What sets the GBU.Q apart

Legally compliant. Complete coverage of the six GDA design areas: Work content, work organization, social relations, work environment, new forms of work, psychological factors.

ISO-45003-kompatibel. Methodologically compatible with the international standard for mental health in the workplace.

Differentiated. Answer-dependent pop-up questions, indicator and differentiation questions – causes are not only displayed, but also understood in terms of content.

Leadership sensitive. Separate indicators for direct and higher-level managers, plus optional module on leadership experience from an FC perspective.

Current. New in 2026.1: digital communication density, psychological safety, accessibility, mobile work, boundary violations, cultural factors.

Open. Qualitative (multilingual) text fields on technology, conflict culture, leadership and free feedback supplement the quantitative measurement.

For whom

GBU.Q is aimed at BGM managers, occupational safety specialists, HR and personnel managers, works and staff councils and management who want to base their risk assessment of mental stress on an up-to-date, scientifically sound and legally compliant tool.


Frequently asked questions about the risk assessment of mental stress

Which questionnaire do you recommend?

The honest answer: it depends. We recommend the COPSOQ for European and multinational projects because there are validated language versions in Scandinavia, France and the Netherlands. It is often too unspecific for corporate development in Germany. The difference lies in the wording of the question: “I am satisfied with my manager” is useless as an item for a GBU – no measure can be derived from it. “Overall, I am satisfied with the way I or my team is managed by my direct manager” is operationally precise and leads to a clear result. This is exactly what our Eudemos GBU.Q is designed for. Regardless of the instrument selected, the following applies: additional scales for the sector and activity are not an option, but a must – police, fire department, nursing, educators, psychiatry or handling hazardous substances cannot be mapped with a standard instrument.

Why are mean values and sector comparisons not sufficient in the evaluation?

Because they systematically hide the problem. A department with 30 percent highly stressed and 70 percent unstressed employees has an inconspicuous mean value – and a serious problem. If you only see the average, you see nothing. Eudemos therefore works with response distributions, extreme group comparisons and area-differentiated reports.
Industry comparison values are overrated for the same reason: a stress factor can be positive in an industry comparison and still show an absolutely urgent need for action – and vice versa. Decisions are not made against the industry average, but against the actual impact in the specific group.

How often should the risk assessment be repeated?

The Occupational Health and Safety Act does not specify a clear deadline for this. In legal terms, a distinction is made between two things that are often confused in practice: the annual updating obligation and the complete repetition. Updating means checking once a year whether new stresses have arisen – due to reorganization, new forms of work, changes in technology, changes in management or changes in work volumes. The complete repetition of the survey every two to three years is appropriate in standard supervisory practice.
Nevertheless, we recommend a different approach – and thus follow the logic of ISO 45003: the risk assessment is transformed from a one-off project into a continuous process. For us, this means a complete survey with GBU.Q every two to three years, with annual mini-checks in between for the areas in which the last round showed conspicuous values. In parallel, a dashboard with current HR key figures as early indicators: Overtime volume, absences and sick days, fluctuation, entries into the BEM, use of the in-house counselling service, utilization rates of critical functions.
The advantage of this logic: the GBU is no longer perceived as a regulatory obligation, but as an ongoing control parameter. Measures derived from the last survey are worked on during the year. The effectiveness check in accordance with Section 3 ArbSchG is therefore no longer a separate process, but part of regular operations. And for the supervisory authorities – who are taking an increasingly close look at whether documentation is meant seriously – this creates a seamless chain of evidence.

What happens if a manager is rated poorly in the survey?

Not a tribunal, but a support meeting. Managers have a dual role: part of the project and often the subject of the results themselves. Many are themselves overloaded, sandwiched between top and bottom. We recommend setting up a regular “management consultation” process, where every manager with critical values has their own meeting in which the findings are explained, the context is understood and realistic next steps are agreed. As a rule, this leads to appreciative solutions that promote development.

Who moderates the results workshops?

Differentiated according to findings. In departments with non-critical results, the manager moderates the process themselves – GBU topics are core management topics. In departments with conspicuous findings, external Eudemos moderators moderate so that the manager does not fall into a defensive role. In addition, we conduct a separate management workshop separately from the teams – one of the most valuable but most frequently omitted process steps.

What types of measures result from the process?

Five types of measures with different mandates: individual (BGF, resilience, EAP, return-to-work interviews), bilateral (welfare and employee interviews, agreements), team (meeting structure, team rules, Kanban, Scrum), with experts (HR, BGM, occupational health and safety specialist, IT) and strategic (staffing, process changes, structural reorganizations). Types 1 to 3 are the responsibility of the manager. Types 4 and 5 are handed over to a working group with steering committee members and decision-makers. Classic mistakes are the focus on 1-3 and the delegation of 4-5 back to the direct superiors.

Why do you recommend external support if we have an in-house OHM manager?

First reason: because middle management has a structural motive to filter problems upwards. External consultants can communicate with management directly and without this filter logic.
Second reason: If management issues or political tensions become apparent, the moderator must be able to maintain neutrality – an internal health manager often cannot do this without jeopardizing their position in the company. In companies with fewer than 100 employees, self-implementation with OHM tools is an option.
Third reason: Because OHM management is often only a partial function and there is usually too little capacity available.

How is anonymity ensured?

Through strict minimum group sizes and fine-grained rights in the portal. Our data protection officers recommend at least eight potential and at least five actual participants per evaluation group. Below that, no evaluation is carried out. Via AGIONT, each manager automatically receives exactly the reports for which they are authorized.

Why do you measure not only stress, but also exhaustion, irritability and sleep disorders?

Because stress is abstract for the management. An exhaustion rate of 40 percent in a department is not. The Eudemos GBU.Q deliberately measures the outcome part – the consequences of stress and motivational health such as inner resignation and the intention to quit – because it is the decisive lever in communication with board members. Optionally, we supplement the Work Ability Index, which according to van den Berg (2010) indicates an average loss of productivity of 26 percent with poor values.

What happens if the management does not implement the recommended measures?

Under labor law, the employer has the final decision-making power, but must prove at the next GBU that it has done something effective, taking into account economic and health interests. In economic terms, something else happens, and more quickly: employees who perceive that a GBU is not being taken seriously make the decision to resign – usually the high-performing ones. A negative selection process is set in motion. The most expensive measure in a GBU is usually the one that is not taken. Diplomatic skill is needed when communicating with management and, in the public sector, with politicians.
