Nearly all college student smokers also drink alcohol, and smoking and heavy-episodic drinking (HED) commonly co-occur. However, few studies have examined the factors that concurrently influence smoking and HED among college students and, to date, no interventions have been developed that target both HED and smoking in this population. The objective of the current study was to develop and evaluate a mobile feedback intervention that targeted HED and smoking. Participants (n = 94) were non-treatment seeking college students (mean age = 20.5, SD=1.7) who engaged in at least one HED episode in the past two weeks and reported concurrent smoking and drinking at least once a week. Participants were randomized to either receive the mobile intervention for 14 days, complete mobile assessments (without intervention) for 14 days, or complete minimal assessments (without intervention or mobile assessments). At a 1-month follow-up, in comparison to the minimal assessment condition we observed significant reductions in the number of cigarettes per smoking day in both the mobile intervention (d=0.55) and mobile assessment conditions (d=0.45). Among those randomized to the mobile intervention, receiving more modules of the intervention was significantly associated with a lower likelihood of any drinking during the 14-day assessment period and significant reductions in smoking at 1-month follow-up. The mobile intervention did not result in significant reductions in HED or concurrent smoking and drinking. Future research should continue to examine ways of using technology and the real-time environment to improve interventions for HED and smoking.

Findings did not support the enabling hypothesis. Although the project-based Housing First program did not require abstinence or treatment attendance, participants decreased their alcohol use and alcohol-related problems as a function of time and intervention exposure.

Some individuals who engage in heavy drinking following treatment for alcohol use disorder may function as well as those who are mostly abstinent with respect to psychosocial functioning, employment, life satisfaction and mental health.

Background and Aims The terms “binge drinking” and “heavy drinking” are both typically operationalized as 4+/5+ standard drinks per occasion for women/men and are commonly used as a proxy for non-problematic (<4/<5) versus problematic (4+/5+) drinking in multiple research contexts. The Food and Drug Administration in the United States (US) recently proposed the 4+/5+ criterion as a primary efficacy endpoint in their guidance for trials examining new medications for alcohol use disorders (AUDs). Internationally, similar cut-offs have been proposed, with the European Medicines Agency having identified reductions in the number of heavy drinking days (defined as 40/60g pure alcohol in women/men) as a primary endpoint for efficacy trials with a harm reduction goal. Analysis and Evidence We question the validity of the 4+/5+ cutoff (and other similar cutoffs) on multiple accounts. The 4+/5+ cutoff has not been shown to have unique predictive validity or clinical utility. The cutoff has been created based on retrospective self-reports and its use demonstrates ecological bias. Given strong evidence that the relationship between alcohol consumption and problems related to drinking is at least monotonic, if not linear, there is little existing evidence to support the 4+/5+ cutoff as a valid marker of problematic alcohol use. Conclusions There is little empirical evidence for the 4+/5+ units per occasion threshold for “binge” or “heavy” drinking in indexing treatment efficacy. Further consideration of an appropriate threshold seems to be warranted.

Background Housing first (HF) programmes provide low-barrier, nonabstinence-based, immediate, supportive and permanent housing to chronically homeless people who often have co-occurring substance-use and/or psychiatric disorders. Project-based HF programmes offer housing in the form of individual units within a larger housing project. Recent studies conducted at a specific project-based HF programme that serves chronically homeless individuals with alcohol problems found housing provision was associated with reduced publicly funded service utilisation, decreased alcohol use, and sizable cost offsets. No studies to date, however, have qualitatively explored the role of alcohol use in the lives of residents in project-based HF. Methods We collected data in a project-based HF setting via naturalistic observation of verbal exchanges between staff and residents, field notes taken during staff rounds, and audio recorded staff focus groups and resident interview sessions. Qualitative data were managed and coded using a constant comparative process consistent with grounded theory methodology. The goal of the analysis was to generate a conceptual/thematic description of alcohol’s role in residents’ lives. Results Findings suggest it is important to take into account residents’ motivations for alcohol use, which may include perceived positive and negative consequences. Further, a harm reduction approach was reported to facilitate housing attainment and maintenance. Residents and staff reported that traditional, abstinence-based approaches are neither desirable nor effective for this specific population. Finally, elements of the moral model of alcohol dependence continue to pervade both residents’ views of themselves and the community’s perceptions of them. Conclusions Findings suggest it is necessary to set aside traditional models of alcohol use and approaches to better understand, align with, and address this population’s needs. In doing so, we might gain further insights into how to enhance the existing project-based HF approach by applying more tailored, alcohol-specific, harm reduction interventions.
