What this trial studies

This cluster randomized controlled trial evaluates the effectiveness of the ASCEND intervention, which trains workplace supervisors in Dutch Small and Medium-sized Enterprises (SMEs) to better support their employees' mental health. The intervention aims to enhance supervisors' confidence, mental health literacy, and ability to advocate for mental health initiatives. Data will be collected through online questionnaires from both supervisors and their supervisees, with a focus on measuring changes in mental health outcomes and absenteeism rates. The study also includes a qualitative evaluation phase to gather insights from participants.

Who should consider this trial

Good fit: Ideal candidates for this study are supervisors and their supervisees working in SMEs in the Netherlands, particularly those who can communicate in Dutch or English.

Not a fit: Patients who may not benefit include those working in organizations with fewer than 10 employees or those not located in the Netherlands.

Why it matters

Potential benefit: If successful, this intervention could significantly improve workplace mental health support, leading to better employee well-being and reduced absenteeism.

How similar studies have performed: Other studies have shown success with similar interventions aimed at improving workplace mental health, indicating a promising approach.
