Evaluating the effectiveness of a CRSCE-based de-escalation training program among psychiatric nurses: a study protocol for a cluster randomized controlled trial.

Background: The high incidence of workplace violence (WPV) in clinical mental health settings has caused a series of negative impacts on nurses, which has subsequently increased public concern. De-escalation (DE) is recommended as a training program which aims at providing nurses with skills and strategies to more effectively respond and manage WPV. Very few studies have examined the effectiveness of DE training, with current studies possessing various limitations due to their design and small sample sizes. By using a cluster randomized controlled design, the proposed study aims to evaluate the effectiveness of a CRCSE-based DE training programs among psychiatric nurses.

Method: A cluster randomized controlled trial, with a 6-month follow-up period after the end of the intervention, will be conducted among psychiatric hospitals in Guangdong, China. The randomization unit is each involved psychiatric hospital. Participants in the control group will be assigned to routine WPV management training, participants of the intervention group will undergo the same training while additionally receiving DE training. The DE training will include the following five modules: communication, response, solution, care, and environment (CRSCE). Primary outcomes are objective clinical indicators, which will be extracted from the information systems of the enrolled hospitals. These include the incidence of WPV, injuries caused by WPV, and the use of coercion (physical restraint and seclusion) by nurses. Secondary outcomes, aims at evaluating the effects of DE training on nurses, include the capacity of DE, DE confidence, level of job burnout, and professional quality of life. Data will be collected at baseline (T), at 3 months (T, intervention completed), and at 6 months after intervention (T, follow-up).

Discussion: This study will offer trial-based evidence of the efficacy of a DE training program targeted at WPV among psychiatric nurses. DE training is expected to reduce both the total incidence and negative impacts of WPV, with additional improvements in psychiatric nurses' coping skills.
