Development of Mobile Contingency Management for Cannabis Use Reduction.

Many interventions for cannabis use disorder (CUD) are associated with decreases in frequency and quantity of use but fail to increase overall rates of sustained abstinence. It is currently unknown whether reductions in use (in the absence of sustained abstinence) result in clinically significant improvements in functioning. The objective of this study was to refine a mobile contingency management approach to reduce cannabis use to ultimately evaluate whether reductions in frequency and quantity of cannabis are related to improvements in functional and mental health status.

Racial and Sociodemographic Disparities in Internet Access and eHealth Intervention Utilization Among Veteran Smokers.

Introduction: Access to the internet at home may be an important barrier to electronic health (eHealth) smoking cessation interventions. The current study explored possible sociodemographic disparities in access to the internet at home among veteran smokers.

Methods: Data from participants proactively recruited and enrolled in a randomized smoking cessation effectiveness trial (N = 408) that compared a web-based smoking cessation intervention to Veterans Affairs (VA) usual care were used to examine the demographic attributes of smokers with and without internet access at home.

Comparative Effectiveness of an Internet-Based Smoking Cessation Intervention Versus Clinic-Based Specialty Care for Veterans.

Introduction: The primary objective of this project was to examine the effectiveness of an Internet-based smoking cessation intervention combined with a tele-health medication clinic for nicotine replacement therapy (NRT) compared to referral to clinic-based smoking cessation care.

Methods: A total of 413 patients were proactively recruited from the Durham VA Medical Center and followed for 12 months. Patients were randomized to receive either a referral to VA specialty smoking cessation care (control) or to the Internet intervention and tele-health medication clinic.

Abstinence Reinforcement Therapy (ART) for rural veterans: Methodology for an mHealth smoking cessation intervention.

Introduction: Smoking is the most preventable cause of morbidity and mortality in U.S. veterans.

Latent Factor Structure of Posttraumatic Stress Disorder.

The current study examined the latent factor structure of posttraumatic stress disorder (PTSD) based on criteria in a sample of participants ( = 374) recruited for studies on trauma and health. Confirmatory factor analyses (CFA) were used to compare the fit of the previous 3-factor model of PTSD to the 4-factor model specified in as well as to a competing 4-factor "dysphoria" model (Simms, Watson, & Doebbeling, 2002) and a 5-factor (Elhai et al., 2011) model of PTSD.

The prevalence of posttraumatic stress disorder in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans: a meta-analysis.

Literature on posttraumatic stress disorder (PTSD) prevalence among Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) veterans report estimates ranging from 1.4% to 60%. A more precise estimate is necessary for projecting healthcare needs and informing public policy.

Multicomponent smoking cessation treatment including mobile contingency management in homeless veterans.

Introduction: Smoking rates are 80% among persons who are homeless, and these smokers have decreased odds of quitting smoking. Little is known about relapse rates among homeless smokers. More information is needed regarding both quit rates and innovative methods to treat smoking cessation among homeless smokers.

The effect of draft DSM-V criteria on posttraumatic stress disorder prevalence.

Background: This study was designed to examine the concordance of proposed DSM-V posttraumatic stress disorder (PTSD) criteria with DSM-IV classification rules and examine the impact of the proposed DSM-V PTSD criteria on prevalence.

Method: The sample (N = 185) included participants who were recruited for studies focused on trauma and health conducted at an academic medical center and VA medical center in the southeastern United States. The prevalence and concordance between DSM-IV and the proposed DSM-V classifications were calculated based on results from structured clinical interviews.
