P-96 Stop for stress – a randomized controlled trial of an online intervention for work-related stress

Introduction

In Denmark, many afflicted with severe work-related stress will not receive specialised treatment despite the existence of evidence-based psychological interventions. This can be due to limited availability, geographical distance, and stigma. Online interventions can overcome these barriers and are as effective as face-to-face interventions. At Aarhus University Hospital we developed and pilot-tested a therapist-guided online intervention for work-related stress called Stop for Stress derived from the evidence-based group intervention MARS (Measures Against Work-Related Stress). The present study aims to compare Stop for Stress and MARS in a multicentre randomized controlled trial (RCT).

Materials and Methods

The RCT is performed as a non-inferiority trial with MARS being treatment as usual. We wish to recruit 220 patients with severe work-related stress referred to the departments of occupational medicine in Aarhus and Odense, Denmark. Patients will be randomised to the two interventions, and outcomes will be measured at 0, 1.5, 3, and 12 months. The interventions are comparable in content, length, and time consumption. Primary outcomes are perceived levels of stress and stressors in the work environment. Additional outcomes are mental health symptoms, daily and cognitive functioning, heart rate variability, and register data on sickness absence, healthcare service utilization, and psychotropic drug prescriptions.

Results

We will quantify if the interventions show comparable effectiveness. Moreover, we aim to identify indicators of enhanced outcomes for the two interventions based on demographics, degree of stress, and cognitive functioning. This can be used to guide future allocation of patients. Lastly we expect the interventions to be equally effective at the two departments, demonstrating successful dissemination of the interventions.

Conclusion

The Stop for Stress intervention is a promising format for delivering an intervention for work-related stress. If proven effective, the intervention can decrease inequality in healthcare.
