Introduction: The police officer occupation is a high-risk profession, with significantly more traumatic and stressful events than other occupations. Key factors for the health of police officers have been found to be related to intra-interpersonal, occupational, and organizational factors. However, the mechanisms underlying why is inconclusive. This protocol therefore intends to explain the approach for conducting both a scoping review, and systematic review. The overall aim of the reviews is to investigate patrolling police officers' life contexts with the intention to identify barriers and resources that affect their lifestyle and health.

Methods: The protocol is reported according to the PRISMA-P guidelines, with PROSPERO number: CRD42020190583. Searches will be carried out in SCOPUS, Web of Science, PubMed, OpenGrey, and EBSCO (Academic Search Premiere, APA PsychINFO, CINAHL, SocINDEX). Two independent raters will screen articles and conduct the critical appraisal. Analyses include Arksey and O'Malley's methodology for the scoping review, and a narrative synthesis for the systematic review, including critically appraising the total body of evidence in the systematic review.

Discussion: The purpose of the reviews is to understand patrolling police officers' life contexts, and support future development of an assessment that measures patrolling police officers' life balance from a contextual viewpoint.
