Effectiveness of a workshop-based intervention to reduce bullying and violence at work: A 2-year quasi-experimental intervention study.

Introduction: Bullying and violence at work are associated with reduced wellbeing of the victims, but few evidence-based interventions are available to prevent these offensive behaviours. We developed and examined the effectiveness of an intervention aimed at prevention of bullying and violence at work through modifications in psychosocial work environment.

Methods: In accordance with pre-published protocol, employees and supervisors of 12 work units in 3 cities (intervention group A: n = 315; intervention group B: n = 271) received a workshop-based intervention on organizational practices to prevent bullying and violence, including supervisor support, supervisor justice, workplace social capital, and psychological safety and were compared to a reference group (n = 2310) which did not receive the intervention.

Effectiveness of a workplace intervention to reduce workplace bullying and violence at work: study protocol for a two-wave quasi-experimental intervention study.

Introduction: Bullying and violence at work are relatively common in Finnish public sector workplaces. Previous research has demonstrated their association with increased risk of poor health and well-being, but only few intervention studies exist. The aim of this protocol paper is to describe the development and assessment of the effectiveness of a workplace intervention aimed at reducing these harmful phenomena.
