Posttraumatic stress and distress tolerance in relation to opioid misuse and dependence among trauma-exposed adults with chronic pain.

Posttraumatic stress symptoms have been associated with opioid misuse and dependence among adults with chronic pain. Lower levels of perceived distress tolerance (i.e.

Disentangling the association between PTSD symptom heterogeneity and alcohol use disorder: Results from the 2019-2020 National Health and Resilience in Veterans Study.

Veterans are at increased risk of comorbid posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) relative to civilians. Few studies have explored the association between distinct PTSD symptoms and AUD in veterans, and existing findings are highly discrepant. This study aimed to address this gap and equivocal association by evaluating which PTSD symptom clusters are most associated with AUD in a veteran sample using the 7-factor 'hybrid' model of PTSD.

Tobacco use severity in relation to opioid misuse and dependence among adult tobacco users with chronic pain: The moderating role of pain-related anxiety.

The opioid epidemic is a significant public health crisis that is often linked to chronic pain management. One ensuing consequence of long-term opioid use for chronic pain is a high potential for opioid misuse and dependence. Although tobacco is commonly used among individuals with chronic pain, it is associated with an increased risk for opioid-related problems.

Dispositional gratitude and mental health in the U.S. veteran population: Results from the National Health and Resilience Veterans Study.

Dispositional gratitude may be linked to positive mental health outcomes, yet population-based data on this association are lacking. Military veterans are an ideal population in which to examine this question given high rates of psychiatric morbidities and efforts to promote psychological resilience in this population. Data were analyzed from a nationally representative sample of 3151 U.

COVID-19 and Anxiety Sensitivity Across Two Studies in Argentina: Associations with COVID-19 Worry, Symptom Severity, Anxiety, and Functional Impairment.

Background: The novel 2019 SARS2-Coronavirus (COVID-19) has had a devastating physical health, mental health, and economic impact, causing millions of infections and hundreds of thousands of deaths. While COVID-19 has impacted the entire world, COVID-19 has disproportionately impacted low-income countries, particularly in South America, causing not only increased mortality but also increased associated mental health complaints. Anxiety sensitivity (AS), reflecting fear of anxiety-related physical sensations, may be particularly important to understand COVID-19 mental health effects among Latinx individuals in South America (Argentina).

The National Health and Resilience in Veterans Study: A Narrative Review and Future Directions.

United States (U.S.) veterans are substantially older than their non-veteran counterparts.

Dissociative symptoms predict risk for the development of PTSD: Results from the National Health and Resilience in Veterans Study (NHRVS).

Dissociative symptoms following trauma exposure, such as derealization (i.e., feeling that one's experience is strange and unreal) and depersonalization (i.

Dynamic interplay between PTSD symptoms and posttraumatic growth in older military veterans.

Background: Posttraumatic growth (PTG) refers to positive psychological changes that may occur after experiencing a traumatic event. While cross-sectional studies have suggested that posttraumatic stress disorder (PTSD) is associated with greater PTG, few longitudinal studies have evaluated interrelationships between PTSD and PTG. Further, little is known about which specific symptom clusters of PTSD and coping mechanisms may drive PTG over time.

Depression and Cognitive Dysfunction in Older U.S. Military Veterans: Moderating Effects of BDNF Val66Met Polymorphism and Physical Exercise.

Objective: Depression is associated with increased risk for cognitive dysfunction, yet little is known about genetic and behavioral factors that may moderate this association. Using data from a nationally representative sample of older U.S.
