Alcohol use remains a major public health concern and economic burden. Extant literature suggests that young adulthood is a particularly high-risk developmental period for heavy drinking. Given this, it is imperative to understand possible risk and protective factors for heavy drinking and related consequences during this risky developmental period. Prior research has shown that both drinking history and alcohol response (AR) are consistent predictors of future drinking outcomes. However, it is unclear how they may work together to confer this risk. The current study aimed to fill this gap in the literature by examining how alcohol use trajectories across adolescence and early adulthood impacted relations between AR after an alcohol challenge and drinking outcomes over a 2-year period in a sample of young adult moderate to heavy drinkers. Results showed that both drinking history and AR were independently predictive of alcohol outcomes at the 6-month follow-up such that a more extensive drinking history, greater high arousal positive effects, and lesser low arousal negative effects predicted greater drinking and alcohol-related problems 6-months later. However, drinking history and AR were largely not predictive of change in drinking outcomes over time. Finally, AR did not mediate the relationship between drinking history and later alcohol-related outcomes. This is the first study to address relations among drinking history, AR, and later drinking outcomes using a longitudinal alcohol challenge design with a full account of early drinking history. Future research would benefit from inclusion of a broad range of drinkers and longer follow-up assessments to better understand the complex pathways of risk from early drinking history and AR to future drinking outcomes. Such efforts may increase the understanding of who is at greatest risk and/or would benefit most from specific intervention programs.

The purpose of this literature review is to examine barriers to the implementation of evidence-based practices (EBPs) for alcohol treatment and approaches to facilitate adoption of EBPs in alcohol treatment settings. Although EBPs represent the most effective forms of treatment, many treatment centers continue to use treatments that lack an empirical foundation. Examining current research on implementation barriers allows for a more complete understanding of factors that may prevent treatment centers from adopting EBPs, and a categorization of EBP implementation strategies and rates of adoption may aid programs seeking to utilizes EBPs. This literature review is also designed to inform a future study of EBP implementation in treatment centers in the greater Phoenix area, which will ultimately serve as a resource to individuals seeking EBPs in the local community. Research on barriers conveyed that there are two types of barriers: global and EBP specific. At the global level, there are core barriers that must be addressed before successful implementation is possible. These barriers include organization and staff barriers. EBP specific barriers should be attended to after global barriers have been addressed. Research on implementation strategies conveys that multipronged approaches are the most effective, and should focus on addressing global barriers. Treatment centers that have successfully implemented EBPs provide valuable information to the development of new implementation strategies. Lastly, research on rates conveys the implementation of EBPs is increasing over time, however the research in this area has many limitations that must be addressed in future research to determine realist rates.

Adolescent and young adult alcohol use is a major public health concern given that it is the most widely used substance by teenagers. This is particularly concerning given the important biological and environmental changes that occur during this developmental period. Therefore, it is not surprising that alcohol use in adolescence is associated with a variety of negative outcomes including alcohol-related consequences, poor academic performance, aggression, and difficulty transitioning to adulthood. Because of this, it is imperative to better understand alcohol use during this time. While there are numerous measures that aim to capture adolescent alcohol use, there is not currently a measure that gathers comprehensive information on alcohol use across adolescence and into early adulthood. Therefore, we developed the Comprehensive Adolescent Drinking History Form (CADHF). The CADHF gathers detailed drinking information for each year since the onset of first regular use, including quantity and frequency of both regular use and periods of heaviest drinking. Additionally, the CADHF collects information on the participants' aggregate drinking experiences between their age of onset and age of first regular use. Using a sample of young adults who completed an alcohol challenge study, we sought to examine (1) whether route of administration of the measure impacts results, (2) which CADHF are most useful, and (3) whether the CADHF shows concurrent, convergent, and incremental validity. Results showed that, the CADHF can be administered online or over the phone and all eight indices provide valuable information depending on the research question. Additionally, strong significant correlations between the CADHF with the Timeline Follow Back (TLFB) and the Young Adult Alcohol Consequences Questionnaire (YAACQ) suggest convergent and concurrent validity. Finally, the CADHF predicted concurrent and future alcohol-related problems over and above the gold standards of alcohol consumption measures; age of onset, age of first intoxication, and the TLFB. This is the first study to retrospectively assess participant's comprehensive alcohol consumption and fills a major gap in the literature. The CADHF has the potential to inform the timing of prevention and intervention efforts and provides unique information from the current gold standards of alcohol consumption measures.
