Background: Posttraumatic stress disorder (PTSD) and physical health conditions commonly co-occur and are both prevalent among military personnel. This study examined how courses of PTSD (no PTSD, remitted, new onset, persistent/recurrent) are associated with physical health conditions, among a population-based sample of Canadian military personnel.
Method: We analyzed data from the 2002 Canadian Community Health Survey-Mental Health and Well-being-Canadian Forces supplement (CCHS-CF) and the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-Up Survey (CAFVMHS; N = 2941).
SUMMARY The fear-avoidance model of chronic pain has stimulated extensive research and the development of a variety of interventions focused on reducing pain-related fear, avoidance behavior and functional disability in individuals with chronic pain. Although there is considerable evidence supporting the model, oversight of potentially important factors and inconsistent findings regarding postulated pathways have led to proposed model revisions. The purpose of this brief narrative review is to provide an overview of the original model, highlight key model revisions and review existing research that directly analyzed the pathways proposed in the original and revised models.
