Article
Background/purpose: Acute subjective alcohol effects appear to play an important role in predicting alcohol hangover. However, no studies have used a laboratory-based alcohol challenge to examine the concurrent or longitudinal effects of subjective alcohol responses on hangover frequency. As such, we investigated the direct and indirect effects of...

Research has attempted to explain how emotion dysregulation and impulsivity relate to alcohol use problems. This study extended the literature by testing different pathways to problem alcohol use. We hypothesized that approach impulsivity/disinhibition and alcohol use frequency would mediate the relationship between emotion dysregulation and negati...
Article
Objective This study investigated the rates of and change in past-year antidepressant use from 1999 to 2017 among a representative sample of Ontario adults and past-year alcohol users and problem drinkers. It examined whether alcohol use and problem drinking are associated with antidepressant use over time, whether gender moderated the effect of pr...
Article
Objective: While the U.S. adult smoking rate has declined, Black smokers disproportionately face more barriers to accessing brief effective tobacco cessation treatments compared with other racial groups. This study developed and tested the effects of a novel, evidence-based, brief smoking intervention culturally targeted for disadvantaged Black smo...
Article
Background & Aims Research shows that sensitivity to certain alcohol responses conveys risk for problem drinking. This study aimed to determine if high‐risk adolescent drinkers infuse more alcohol and experience greater alcohol‐induced stimulation and wanting and less sedation than low‐risk adolescent drinkers. Design and participants Ninety‐two l...
Article
Impulsivity and subjective response (SR) to alcohol (i.e., individual differences in sensitivity to pharmacologic alcohol effects) are both empirically supported risk factors for alcohol use disorder; however, these constructs have been infrequently studied as related risk factors. The present investigation examined a self-report measure of impulsi...
Article
Introduction: Despite tobacco use as the largest preventable cause of premature death in the US, many healthcare providers continue to lack the knowledge and confidence in employing the Ask, Advise, Refer (AAR) model in tobacco cessation treatment delivery. This pilot study evaluated the feasibility and effectiveness of a novel AAR-styled training...
Article
Objective Research evidence supports the clinical significance of subjective feelings of loss of control over eating; however, limited attention has been given to how this construct is assessed. Two measures have been developed in recent years (i.e., Eating Loss of Control Scale [ELOC] and Loss of Control over Eating Scale [LOCES]), but further val...
Article
Background Alcohol hangovers have been found to be a common and costly consequence of alcohol misuse. However, there is only limited psychometric support for instruments to accurately measure hangovers beyond the college‐age years. This study investigated the psychometric properties of the Hangover Symptom Scale (HSS) and the Hangover Symptom Scale...
Article
Substance use disorders (SUDs) and Cluster B personality disorders (PDs) may have shared risk through profiles of personality and motivational traits. The present study sought to replicate in a national sample of adults past research which found multi-trait profiles that were associated with disinhibitory disorders in a college sample. Another aim...
Article
Background: Despite recent research establishing high rates of comorbidity between hoarding disorder and alcohol use disorders (AUD), no studies have systemically examined the associations between symptoms of hoarding and alcohol use. Moreover, no studies have explored potential mechanisms that may help to explain these relations. Objectives: Th...
Article
Objective: Research on the progression from substance use to dependence typically relies on lifetime retrospective reports of dependence among ever users. We sought to evaluate probability and correlates of dependence among recent (past-year) weekly users of alcohol, nicotine, cannabis, and cocaine through cross-sectional and prospective analyses....
Article
Objective: The misuse of alcohol is related to numerous detrimental health effects. Research has determined anxiety sensitivity (AS) to be a risk factor for problematic alcohol use. To date, no studies have investigated this relationship using a bifactor model of AS. This study used a bifactor model to determine the effects of the general AS facto...
Article
Growing interest in developing more effective smoking cessation treatments has facilitated the need to further investigate cognitive-affective factors that inhibit successful smoking cessation, such as urges to smoke. Research has strongly supported an association between suicidality and smoking, yet no work has investigated whether suicidality may...
Article
Various anxiety-related risk factors have been proposed to contribute to the development of drinking motives. However, little is known about how intolerance of uncertainty (IU), defined as a cognitive bias to interpret ambiguity in a negative fashion, relates to motives for alcohol use. IU, as measured by the IUS-12, is comprised of prospective IU...
Article
The overuse of substances can lead to economic, physical, and social consequences. Previous research has demonstrated associations between time perspective and frequency of substance use, but no studies have investigated time perspective's effect on substance use consequences. This study aimed to fill this gap in the literature. Using an MTurk samp...

Prosociality is one construct included in the developmental propensity model proposed by Lahey and Waldman (2003, 2005) to explain the development of conduct problems in childhood and adolescence. Findings from previous literature on 2 facets of prosociality, dispositional sympathy and respect for rules, suggest that both may have genetic and nonsh...

Previous research found that self-regulation and self-efficacy were linked to substance use abstinence. The present study examined the relationships between changes in self-regulation and self-efficacy as predictors of substance use abstinence. A total of 150 adult individuals (62% female; M age = 37.1 SD = 8.1; 38% male) in substance abuse recover...
