ABSTRACT
Chronic pain and mental health issues occur at higher rates in Veterans than the general population. One widely recognized mental health issue faced by Veterans is post-traumatic stress disorder (PTSD). Trauma symptoms and pain frequently co-occur and are mutually maintained due to shared mechanisms. Many Veterans are also parents. Parental physical and mental health issues significantly predict children's chronic pain and related functioning, which can continue into adulthood. Only 1 U.S.-based study has examined pain in the offspring of Veterans, suggesting a heightened risk for pain. Research to date has not examined the associations between trauma and pain and the dyadic influences of these symptoms, among Veterans, and their children. The current study aimed to describe pain characteristics in Canadian Armed Forces Members/Veterans with chronic pain and their offspring (youth and adult children aged 9-38). Cross-lagged panel models were conducted to examine dyadic relationships between pain interference and trauma symptoms of Canadian Armed Forces Members/Veterans and their offspring. Over half of adult offspring and over one-quarter of youth offspring reported chronic pain. Results revealed effects between one's own symptoms of PTSD and pain interference. No significant effects of parents on offspring or offspring on parents were found. The findings highlight the interconnection between pain and PTSD consistent with mutual maintenance models and a lack of significant interpersonal findings suggestive of resiliency in this unique population. PERSPECTIVE: We characterized chronic pain in the offspring of Canadian Armed Forces Members/Veterans with chronic pain and examined dyadic relationships between PTSD symptoms and chronic pain interference. Findings revealed that PTSD symptoms and pain interference were related within Veterans and offspring, but no dyadic relationships were found, which could reflect resiliency.

Chronic pain in Canadian Veterans is twice that of the general population and the prevalence of their related mental health concerns is alarmingly high. This likely puts their children at an increased risk of developing pain and mental health problems that can pervasively impact daily life and persist into adulthood. Pain care and military culture of (acute and chronic) pain have been identified as a top priority of Canadian Veterans. This study aimed to gain an in-depth understanding of the pain experiences of Canadian Armed Forces families. Thirty-five semi-structured qualitative interviews were conducted. Demographic information was collected; age, gender, and ethnicity were reported. Twelve Canadian Armed Forces members/Veterans, 17 youth, and 6 spouses were interviewed. Ninety-two percent of Veteran participants reported chronic pain. Reflexive thematic analyses generated four themes: 1) Military mindset: herd culture and solider identity, 2) The culture of pain within military families, 3) Inseparability of mental health and pain, and 4) Breaking the cycle and shifting the military mindset. Military culture and identity create a unique context within which pain expression and experience is integrally shaped within these families. This study sheds light on how pain is experienced and perceived within military families and can inform research on and efforts to foster resilience in these families. PERSPECTIVE: This is the first qualitative study to explore the lived experiences of pain in Canadian military families. Findings underscore the key role that military culture and identity plays in how pain is experienced and perceived in all family members.

An assessment of off-site exposure from spills/releases of toxic chemicals can be conducted by compiling site-specific operational, geographic, demographic, and meteorological data and by using screening-level public-domain modeling tools (e.g., RMP Comp, ALOHA and DEGADIS). In general, the analysis is confined to the following: event-based simulations (allow for the use of known, constant, atmospheric conditions), known receptor distances (on the order of miles or less), short time scale for the distances considered (order of 10's of minutes or less), gently sloping rough terrain, dense and neutrally buoyant gas dispersion, known chemical inventory and infrastructure (used to define source-term), and known toxic endpoint (defines significance). While screening-level models are relatively simple to use, care must be taken to ensure that the results are meaningful. This approach allows one to assess risk from catastrophic release (e.g., via terrorism), or plausible release scenarios (related to standard operating procedures and industry standards). In addition, given receptor distance and toxic endpoint, the model can be used to predict the critical spill volume to realize significant off-site risk. This information can then be used to assess site storage and operation parameters and to determine the most economical and effective risk reduction measures to be applied.
