Although staff training is often recommended as an essential part of any comprehensive approach for preventing and managing workplace violence, there is paucity of evidence on the content and effectiveness of such training.

A two arm, cluster randomised, single-blinded, controlled trial among healthcare support workers in nongovernmental organisations (NGOs) and District Health Boards (DHBs) in New Zealand was conducted.

Both the intervention (communication skills) and control condition (mindfulness) were group-based, fully scripted, and structured training interventions that consisted of four once weekly workshops that were facilitated by one of two nonclinical facilitators. Measurements of perceived aggression, psychological well-being, and distress and communication competence were taken pre-, post-, 3 months' post-, and 6 months' postintervention. There was a significant drop in the rate of aggression over time with a mean score and standard deviation of 10.37 (9.169) at baseline dropping…
