Protocol for the development and piloting of a cluster randomised controlled trial for stress prevention, management, and coping mechanism among police officers in Nigeria.

Background: Policing is a stressful occupation. Police officers are exposed to stressors that are inherent in the organization and operations of law enforcement. Similar to their counterparts around the world, many Nigeria police officers are exposed to high levels of stress, making them vulnerable to stress-related mental health conditions and other noncommunicable diseases.
