OBJECTIVE Conceptual models of addiction highlight self-efficacy and motivation as key variables important during a smoking quit attempt; however, recent research has primarily focused on self-efficacy. Given the importance of motivation in these models, a clearer understanding of the effects of motivation during a smoking quit attempt is needed. METHOD This study utilized ecological momentary assessment (EMA) to investigate the dynamic effects of motivation and self-efficacy early in a quit att...
OBJECTIVE Personalized normative feedback (PNF) interventions are effective at reducing hazardous drinking in college. However, little is known about who is most receptive to PNF. College women with a history of alcohol-related incapacitated rape (IR) are at elevated risk for hazardous drinking, but it is unclear what impact intervention messaging may have on this group and how their outcomes compare to those without past IR. To address this gap, this study involved secondary data analysis of a ...
OBJECTIVE Alcohol, tobacco, and cannabis are the three most frequently used drugs in the United States and co-use is common. Alcohol, tobacco, and cannabis use has been separately associated with altered brain structure, and alcohol and tobacco co-use results in decreases in gray matter volume. Less is known about the effect of alcohol and cannabis co-use, and alcohol, tobacco, and cannabis tri-use. Therefore, this study examined the effect of co- and tri-use on gray matter volume, a measure of ...

OBJECTIVE This study examined past-year cannabis use prevalence and sociodemographic and clinical correlates of cannabis use among Veterans Health Administration (VHA) primary care patients in a state with legalized medical cannabis. METHOD Participants were 1,072 predominantly white, male, VHA primary care patients enrolled in a drug screening validation study (2012-2014). Sociodemographic and clinical correlates were examined by past-year cannabis use status. Multivariate regression models, ad...
OBJECTIVE The high rate of statistically significant findings in the sciences that do not replicate in a new sample has been described as a "replication crisis." Few replication attempts have been conducted in studies of alcohol use disorder (AUD), and the best method for determining whether a finding replicates has not been explored. The goal of the current study was to conduct direct replications within a multisite AUD-randomized controlled trial and to test a range of replication metrics. MET...

OBJECTIVE Difficulties identifying emotional facial expressions are commonly observed in alcohol use disorder (AUD). Critically, this work utilizes single-race stimulus sets, although study samples are not similarly constrained. This is particularly concerning given evidence among community samples showing the impact of racial incongruity, giving rise to interpretative caveats. METHOD Community controls (n = 55, 12 Black) and individuals with AUD (n = 46, 9 Black) completed a two-choice emotion ...
OBJECTIVE Alcohol use among college students during 21st birthday celebrations constitutes a well-known example of event-specific drinking when alcohol use is both pervasive and heavy. Less is known about how 21st birthday alcohol use compares to other birthday celebrations during young adulthood, whether similar increases occur for cannabis use on 21st birthdays, and whether the "21st birthday effect" is similar for noncollege young adults. Alcohol and cannabis use during 19th to 25th birthday ...
OBJECTIVE Cannabis use disorder (CUD) is the most common non-alcohol related substance use disorder (SUD) in the United States and is especially prevalent among returning veterans. The long-term mental health correlates of CUD remain unknown, which is significant given the rise in legalization and also recreational and medicinal cannabis use nationally. METHOD Using a gender-balanced, national sample of 1,649 veterans (n = 115 with CUD; 75.2% White; M age = 37.49, SD = 9.88), we used latent grow...

BACKGROUND Racial discrimination is prevalent among Black Americans, and may increase risk for alcohol use and related problems. Understanding the mediating and moderating factors in the pathways linking racial discrimination to alcohol use outcomes is important for prevention and intervention efforts. We tested depressive symptoms as a mediator and ethnic-racial identity as a moderator in the relation between racial discrimination and alcohol use outcomes among Black American young adults. METH...
Objective This study captured the interrelationships among craving, negative affect, and positive and negative social exchanges in the daily lives of patients in residential treatment for opioid use disorders (OUDs). Method Participants were 73 patients (77% male), age 19 to 61 (Mage = 30.10, SDage = 10.13) in residential treatment for OUD. Participants completed a smartphone-based survey 4 times per day for 12 consecutive days that measured positive and negative social exchanges (Test of Negati...
