Problematic Driving in Former Service Members: An Evaluation of the Driving Behavior Survey in Veterans with Posttraumatic Stress Disorder

Publication date: Available online 18 August 2019Source: Journal of Anxiety DisordersAuthor(s): Joshua D. Clapp, Denise M. Sloan, William Unger, Daniel J. Lee, Janie J. Jun, Scott D. Litwack, J. Gayle BeckAbstractDespite high levels of traffic-related mortality, injury, and impairment among former service members, measures validated to assess problematic driving in this population remain limited. The current study examined characteristics of the Driving Behavior Survey (DBS) in male veterans (76.3% White; age: M = 56.4, SD = 12.3) meeting criteria for PTSD. Confirmatory factor analyses indicated acceptable fit of a 3-factor model specifying dimensions of anxiety-based performance deficits, exaggerated safety/caution, and hostile/aggressive driving behavior. Concurrent associations with indices of anxiety, depression, trauma history, and clinician-rated PTSD were consistent with small (r = .10 - .29) to medium (r = .30 - .49) effects. Discriminative validity was noted through elevations in performance deficit (d = .26), safety/caution (d = .50), and hostile/aggressive (d = .39) scales relative to published data from student drivers. Scores comparable to civilian motorists with accident-related PTSD help to qualify the severity of problematic driving behavior in trauma-exposed veterans.

Posttraumatic stress disorder (PTSD) is a complex, often debilitating, disorder that has far-reaching effects, including anxiety, depression, burnout, and compassion fatigue. Working as a critical care unit nurse can be physically and emotionally demanding. Critical care nurses are at increased risk of developing PTSD compared with general care nurses. Employers are also affected due to increased rates of attrition, absenteeism, and general decreased quality in patient care. There is conflicting evidence related to which factors contribute to PTSD but increased resilience holds the most promise for preventing PTSD and its ...

Conclusion: Our study suggests there are high prevalence rates for mental health and addiction conditions in patients attending the out-of-hours clinic 18 months after the wildfires, with significant associations between multiple variables and likely PTSD, MDD, and GAD. Further studies are needed to explore the impact of population-based mental health interventions on the long-term mental health effects of the wildfires.

e;e M Abstract The pregnenolone-progesterone-allopregnanolone pathway is receiving increasing attention in research on the role of neurosteroids in pathophysiology, particularly in stress-related and drug use disorders. These disorders involve an allostatic change that may result from deficiencies in allostasis or adaptive responses, and may be downregulated by adjustments in neurotransmission by neurosteroids. The following is an overview of findings that assess how pregnenolone and/or allopregnanolone concentrations are altered in animal models of stress and after consumption of alcohol or cannabis-type drugs, a...

Post-traumatic stress disorder (PTSD) is a common, often debilitating mental health condition that occurs in some people who have experienced trauma. It can have a negative impact on mood, mimicking depression, and is characterized by petrifying episodes in which affected people re-experience trauma. New research suggests psychotherapy may provide a long-lasting reduction of distressing symptoms. Over the course of a lifetime, many people directly experience or witness trauma, such as sexual assault, violence, or natural disasters. Experts estimate that 10% to 20% of these people will experience acute (short-term) PTSD. So...

Introduction: After a traumatic event, children and adolescents may present several clinical consequences, the most common being Post-Traumatic Stress Disorder (PTSD). Most children and adolescents with PTSD have comorbid disorders, such Attention Deficit Hyperactivity Disorder, depression, attachment and anxiety disorders, sleep disturbances and behavior problems. However, epidemiological studies on the development of PTSD and other psychiatric disorders in children and adolescents as a consequence of a terrorist attack and mass murder are lacking. Long-term follow-up of exposed children and adolescents will help identify...

Objectives: We investigated the relationships of DAD trajectories and negative peer and parental influences, substance use, and mental health among predominantly marijuana-using youth seeking emergency department (ED) treatment. Methods: Data were from a 2-year prospective cohort study of drug-using patients (97.4% used marijuana) ages 14-24 s...
