College student drinking is prevalent and costly to public and personal health, leading to calls to identify and target novel mechanisms of behavior change. We aimed to manipulate drinking identity (a cognitive risk factor for hazardous drinking) via three sessions of narrative writing about a future self. We tested whether writing could shift drinking identity and would be accompanied by changes in alcohol consumption and problems. Participants were college students meeting hazardous drinking criteria (N = 328; M age  = 20.15; 59% women, 40% men, 1% gender-diverse; 60% white; 23% Asian; 12% multiple races; 2% other racial groups; 8% identified as Hispanic/Latino/a/x). The study had a 2 [narrative writing topic: low-risk drinker vs. reduced smartphone use] × 2 [writing perspective: first person vs. non-first-person] × 2 [social network instruction: instructed to include vs. not] factorial design. Outcomes were drinking identity, drinking refusal self-efficacy, alcohol consumption, alcohol-related problems, and craving. Participants completed three writing sessions and online follow-up assessments at 2, 4, and 12 weeks. The study is a registered clinical trial; hypotheses and analyses were preregistered (https://osf.io/vy2ep/). Contrary to predictions, narrative writing about a future self as a low-risk drinker did not significantly impact outcomes. Null results extended to expected interactions with writing perspective and social network instructions. The narrative writing task did not shift drinking or alcohol-related outcomes. Future experimental work may benefit from greater flexibility in conceptualizing a future self, recruiting individuals interested in behavior change, and more sensitive measures of drinking identity., (Copyright © 2023 Elsevier Inc.

Cross-sectional research has demonstrated that endorsing, or acknowledging, and frequently thinking about having a drinking identity are uniquely and positively associated with alcohol consumption and risk for hazardous drinking. In the current investigation, we evaluated whether these facets of drinking identity indicated a latent drinking identity variable. We also investigated whether greater identification with drinking predicted subsequent increases in alcohol consumption and risk for hazardous drinking, and whether higher levels of these drinking behavior variables predicted subsequent increases in identification with drinking. Data were collected from participants (N = 422) near their graduation from college and then again eight months later. Drinking identity endorsement and drinking identity thought frequency were positive indicators of a latent drinking identity variable. Identification with drinking was concurrently, positively associated with both alcohol consumption and risk for hazardous drinking at both time points. Greater identification with drinking at the first assessment predicted subsequent increases in alcohol consumption and risk for hazardous drinking. Surprisingly, the drinking behavior variables did not prospectively predict changes in identification with drinking. These findings support an expanded conceptualization of drinking identity, provide further evidence that greater identification with drinking prospectively predicts more drinking behaviors, and suggest that drinking identity should be considered in interventions to reduce hazardous drinking., (Copyright © 2021 Elsevier Ltd.

Implicit measures of alcohol-related associations or implicit alcohol associations are associated with drinking outcomes over time and can be understood as vulnerability markers for problem drinking. Longitudinal research remains rare, leaving open questions about how implicit alcohol associations themselves change over time and what factors moderate that change. We examined these questions with data from a larger study of first and second year U.S. college students. We investigated how these implicit alcohol associations change over time and potential moderators of those changes (gender, lifetime drinking history, family history of problem drinking, and class standing). A sample of 506 students (57% women) completed baseline demographic measures and implicit measures (variants of the Implicit Association Test [IAT]) assessing associations with drinking and the self [drinking identity], alcohol and excite [alcohol-excite], and alcohol and approach [alcohol-approach]). IATs were completed at 3-month intervals for a total of 8 assessments. Results indicated small, but significant, change in alcohol-excite and alcohol-approach IAT scores over time, and mixed findings for hypothesized moderators. Drinking history moderated change in drinking identity IAT scores, with increases over time among individuals with no history of drinking or no history of intoxication and decreases among individuals with a history of intoxication. Gender moderated change in alcohol-excite IAT scores with greater change among women (vs. men). No significant moderators of change in alcohol approach IAT scores were found. Results point to the importance of evaluating implicit associations' trajectories and identifying additional factors that predict those trajectories and concomitant vulnerability to problem drinking., (Copyright © 2020 Elsevier Ltd.

There is a tremendous global and national (US) burden associated with alcohol misuse and alcohol use disorder (AUD). Further, of the mental health disorders, AUD has the widest treatment gap. Thus, there is a critical need for improved understanding of the etiology, maintenance, and treatment of AUD. The application of cognitive science to the study of AUD has a longstanding history of attempting to meet this need. In this selective review, we identified and focused on four domains of recent (i.e., in the last decade) applications of cognitive science to the study of AUD: implicit cognitive biases, executive function, behavioral economic approaches to alcohol decision making, and functional connectivity neuroimaging. We highlighted advances within these four domains and considered them in the context of dual process models of addiction, which focus on the contribution and interplay of two complementary neurocognitive systems (impulsive and control systems). Findings across the domains were generally consistent with dual process models. They also suggest the need for further model refinements, including integrating behavioral economic approaches and findings from functional connectivity neuroimaging studies. Research evaluating candidate interventions associated with these domains is emergent but promising, suggesting important directions for future research., (Copyright © 2018 Elsevier Ltd.

Problematic alcohol consumption is elevated among those who identify (i.e., associate themselves) with drinking. We extended prior research on drinking identity by considering two dimensions of investment in identity - i.e., mental resources allocated to that identity that may motivate the pursuit of identity-related goals. We considered drinking identity importance (i.e., how important one considers it to be) and drinking identity thought frequency (i.e., how frequently one thinks about it). We investigated these dimensions from two perspectives: an absolute perspective (i.e., investment in drinking identity irrespective of other identities) and a relative perspective (i.e., investment in drinking identity compared to identities associated with other life domains [education, well-being, and personal relationships]). We aimed to evaluate whether these investment dimensions were positively associated with alcohol consumption and risk of alcohol use disorder either in interaction with or in addition to endorsement of drinking identity. College students (N = 521) who were screened for exhibiting hazardous drinking completed self-report measures of alcohol consumption, risk of alcohol use disorder, and drinking identity endorsement and investment. Controlling for gender and drinking identity endorsement, absolute and relative drinking identity thought frequency were uniquely and positively associated with alcohol consumption and risk of alcohol use disorder. Neither absolute nor relative importance of identification with drinking uniquely predicted outcomes. Drinking identity investment, as signaled by absolute and relative frequency of thought related to identification with drinking, may be an additional risk factor and/or clinical target for alcohol consumption and risk of alcohol use disorder., (Copyright © 2018 Elsevier Ltd.
