PREFACE
Rebecca Guest and Ashley Craig
Motor vehicle crashes (MVCs) resulting in physical injury are an all too common experience world-wide that can have devastating outcomes, typified by physical, social and economic consequences for the individual, family and community (Nantulya & Reich, 2002; Ameratunga, Hijar, & Norton, 2006). We are pleased...
Psychological distress associated with a physical injury following a motor vehicle crash (MVC) is a common problem that has potential short, medium and long-term negative impacts. For example, elevated psychological distress can result in psychological disorder such as depression or post-traumatic stress disorder, social isolation, financial distre...
Motor vehicle crashes are associated with a high risk of physical injury that can result in life-long disability and lowered quality of life. Injuries following a motor vehicle crash can be classified as minor to moderate injuries versus severe injuries. Severe injuries include spinal cord injury, severe traumatic brain injury, amputation, permanen...
It is important to determine whether psychological distress associated with musculoskeletal injuries sustained in a motor vehicle crash (MVC), regardless of time of onset, has an impact on compensation outcomes such as claim settlement times and costs. It is equally important to identify factors routinely collected by insurance companies that may c...
The quest for reliable and sensitive biomarkers capable of predicting risk of psychological distress and adaptability following adversity is not a novel idea. Scientists have long speculated that links exist between biological, psychological and social factors that operate to result in resilience or distress. On one hand, the advent of a unifying m...
There is paucity of prospective studies that have examined rates and prognostic indicators of pain severity after a road traffic crash injury. This cohort study involved 1,854 participants aged ≥17 years with a noncatastrophic injury. Primary analyses of pain severity involved 1604 individuals who reported any pain since the injury at baseline Of t...
Physical injury sustained in a motor vehicle crash has a high risk of being associated with significant chronic pain that can last for many years, or for some, a lifetime. Consequently, disability coupled with chronic pain can be a very debilitating problem, as for example, quality of life will certainly be diminished, daily functioning reduced and...
