Objective: The objective of this review is to produce a set of integrated findings of quantitative and qualitative evidence regarding workplace recruitment and retention factors (including departure) of female first responders to inform recommendations for policy and practice.Introduction:Historically, first responder workforces such as police officers, firefighters, search and rescue personnel, medical technicians, and paramedics have been largely male dominated. Over the past few decades, however, there has been a steady increase in the number of women entering this field. However, there is minimal research examining factors that influence the recruitment/retention of female first responders. The intention of this review is to identify barriers and facilitators to recruitment and retention of female first responders and to identify any differences between sexes/genders.Inclusion criteria:This review will summarize qualitative and quantitative research examining factors influencing the recruitment/retention of female first responders. Such factors may include job satisfaction, quality of work life, burnout, compassion fatigue, and intent to remain in the workforce.Methods:MEDLINE (PubMed), CINAHL (EBSCO), PsycINFO (APA), PTSDpubs (formerly PILOTS; ProQuest), Embase (Elsevier), and Scopus (Elsevier) will be searched for studies published in English from 2009 to the present. Unpublished studies will be searched in Google Scholar, and ProQuest Dissertations and Theses Global. Both quantitative and qualitative studies will be screened for inclusion and critically appraised for methodological quality by two independent reviewers. Both types of data will be extracted using JBI tools for mixed methods systematic reviews. A convergent integrated approach to synthesis and integration will be used.Systematic review registration number:PROSPERO CRD42020156524.
