Longitudinal Changes in Combat-Related Posttraumatic Stress Disorder Among Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn Veterans With Hazardous Alcohol Use: The Role of Avoidance Coping.

Military personnel who have experienced combat trauma are at risk for developing posttraumatic stress disorder (PTSD). A greater recognition of the complex array of vulnerability factors that contribute to PTSD severity has led researchers to examine other non-combat-related factors. This longitudinal study examined a number of pre-, peri-, and postdeployment factors hypothesized to contribute to PTSD symptomatology among returning Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans presenting with at least subthreshold PTSD symptoms and hazardous alcohol use in a primary care setting.

Natural Course of Co-Occurring PTSD and Alcohol Use Disorder Among Recent Combat Veterans.

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) commonly co-occur in veterans, yet little is known about the longitudinal course of PTSD and drinking in comorbid populations. This study assessed the natural course of daily alcohol consumption and weekly changes in PTSD symptoms in 112 recent combat veterans over the course of 11 months. Latent class growth mixture modeling was used to classify individuals into distinct classes with similar PTSD symptom and alcohol use growth trajectories.

Predictors of Mental Health Care Utilization in Veterans With Post-Traumatic Stress Disorder Symptoms and Hazardous Drinking.

Objectives: Describe outpatient mental health service use in a sample of recent combat Veterans with post-traumatic stress disorder (PTSD) symptoms and hazardous alcohol use and investigate predictors of mental health care utilization.

Methods: In this prospective study, 126 Veterans with full or subthreshold PTSD and hazardous alcohol use completed a baseline assessment and reported mental health service use through a 12-month follow-up period. Logistic regressions were used to identify factors predicting mental health care utilization.

Ecological momentary assessment of PTSD symptoms and alcohol use in combat veterans.

Despite high rates of comorbid hazardous alcohol use and posttraumatic stress disorder (PTSD), the nature of the functional relationship between these problems is not fully understood. Insufficient evidence exists to fully support models commonly used to explain the relationship between hazardous alcohol use and PTSD including the self-medication hypothesis and the mutual maintenance model. Ecological momentary assessment (EMA) can monitor within-day fluctuations of symptoms and drinking to provide novel information regarding potential functional relationships and symptom interactions.

Coping, PTSD symptoms, and alcohol involvement in trauma-exposed college students in the first three years of college.

The objective of the present study was to examine prospective, bidirectional associations among posttraumatic stress disorder (PTSD) symptoms, coping style, and alcohol involvement (use, consequences) in a sample of trauma-exposed students just entering college. We also sought to test the mechanistic role that coping may play in associations between PTSD symptoms and problem alcohol involvement over time. Participants (N = 734) completed measures of trauma exposure, PTSD symptoms, coping, and alcohol use and consequences in September of their first college year and again each September for the next 2 years.
