Brief Summary
This cluster randomized controlled trial (cRCT) aims to evaluate the effectiveness of the Dutch adaptation of an in-person group intervention for workplace supervisors - Advancing Supervisors' Capacity for Mental Health at Work (ASCEND) - in Dutch Small and Medium-sized Enterprises (SMEs). The ASCEND intervention is designed to equip supervisors with the skills to: i) know when to support their workers; ii) how to direct workers to support, and iii) advocate for action on mental health at work. The primary objectives of this project are to:
- Assess to what extent the Dutch adaptation of the WHO-developed ASCEND intervention is effective in enhancing supervisors' confidence, responsiveness, mental health literacy, and self-care practices, and in reducing supervisor stigma towards mental health conditions within Dutch SMEs.
- Evaluate the impact of the ASCEND intervention on employee outcomes, including mental health and work-related outcomes among supervisees (i.e., subordinates), as well as overall organizational absenteeism rates.
- Identify barriers, facilitators, and key implementation and adoption indicators to support future opportunities for scaling up the ASCEND intervention. Researchers will compare two groups to evaluate the effectiveness of the ASCEND intervention. One group will receive the training (the intervention group), while the other group will receive the training after the final follow-up period (the control group). Data will be collected from both supervisors and their supervisees (i.e., subordinates) via online questionnaires at various time points. In addition, general organizational information, including absenteeism rates, will be gathered through a representative from each participating organization. To further explore the feasibility of scaling up the ASCEND intervention within the Netherlands, qualitative data will be collected through interviews and/or focus group discussions.

Outcome Measures
Primary Outcomes (1)
Supervisor confidence in addressing employee mental health problems
Confidence in addressing employee mental health problems will be measured among supervisors using a 6-item scale used in other trials that investigated a similar intervention. Participants will be asked to rate their degree of confidence from 1 (not confident at all) to 5 (extremely confident) for various activities that are related to the construct of supporting employee mental health. A mean score will be calculated by averaging participants' ratings across all items. Scores range from 1 to 5, with a higher score indicating more confidence.

Study Arms (2)
Advancing Supervisors' Capacity for Mental Health at Work (ASCEND)
EXPERIMENTALParticipants in the treatment group will receive the Dutch adaptation of the ASCEND group intervention, delivered in person over approximately 8 hours in a single day. Participants will be permitted to participate in other programs or training courses after enrolling in the trial.
Control
NO INTERVENTIONSupervisors from organizations in the control arm will receive no ASCEND training during the trial. They will be provided with the ASCEND training approx. 6 months after baseline, after the last follow-up. Participants will be permitted to participate in other programs or training courses after enrolling in the trial.
Interventions
The intervention will consist of a training that incorporates evidence-based content and interactive exercises. Advancing Supervisors' Capacity for Mental Health at Work (ASCEND) covers five core topics designed to equip supervisors with the knowledge and practical skills needed to effectively support the mental health of their employees. The full training is delivered over approximately 8 hours in an in-person group setting. Trainings are facilitated by a trained professional. To support learning, participants will also receive a Manager Reference Booklet during the training. This booklet consolidates key information from the ASCEND training, serving both as a learning aid during the sessions and a practical, quick-reference tool afterward. It includes summaries of key concepts, tips, and exercises, along with space for participants to record notes. Participants receive a certificate for their participation in the training.
