Delay discounting is a phenomenon strongly associated with impulsivity. However, in order for a measured discounting rate in an experiment to meaningfully generalize to choices made elsewhere in ...life, participants must provide thoughtful, engaged answers during the assessment. Classic discounting tasks may not optimize intrinsic motivation or enjoyment, and a participant who is disengaged from the task is likely to behave in a way that provides a biased estimate of their discounting function. We assessed degree of delay discounting in a task intended to vary level of participant motivation. This was accomplished by introducing varying levels of gamification, the application of game design principles to a non-game context. Experiment 1 compared three versions of the delay discounting task with differing degrees of gamification and compared performance and task enjoyment across those variations, while Experiment 2 used two conditions (one gamified, one not). Participants found more gamified versions of the task more enjoyable than the other conditions, without producing substantial between-group differences in most cases. Thus, more polished task gameplay can provide a more enjoyable experience for participants without undermining delay discounting effects commonly reported in the literature. We also found that in all experimental conditions, higher levels of interest in or enjoyment of the task tended to be associated with more rapid discounting. This may suggest that low task motivation may result in less impulsive choice and suggests that participants who find delay discounting experiments sufficiently boring may bias assessments of value across delays.

Background
Heavy alcohol use is common among young adults on weekend nights and is assumed to be intentional. However, little is known about the extent to which heavy consumption is planned prior to ...the onset of drinking and what factors contribute to drinking more than intended. This study investigates drinking intentions at the beginning of an evening and individual and situational factors associated with a subsequent consumption over the course of multiple nights.
Methods
Using a smartphone application, 176 young people aged 16 to 25 (mean age = 19.1; 49% women) completed questionnaires on drinking intentions, consumption, and drinking environments before, during, and after multiple Friday and Saturday nights (n = 757). Multilevel regressions were used to investigate individual‐level and night‐level factors associated with previous drinking intentions and subsequent deviations from intentions.
Results
Participants intended to consume 2.5 drinks (SD = 2.8) per night yet consumed 3.8 drinks (SD = 3.9) on average. Drinking intentions were higher among those who frequently went out at night and engaged in more frequent predrinking. Participants drank more than intended on 361 nights (47.7%). For both genders, the number of drinks consumed before 8 pm, attending multiple locations, and being with larger groups of friends contributed to higher consumption than intended at the individual and the night levels. Heavier consumption than intended also occurred when drinking away from home for men and when going to nightclubs for women.
Conclusions
Making young adults aware of the tendency to drink more than intended, particularly when drinking begins early in the evening, moves from location to location, and includes large groups of friends, may be a fruitful prevention target. Structural measures, including responsible beverage service, may also help in preventing excessive drinking at multiple locations.
Drinking more than intended on weekend nights is common among young adults. Youth intended to consume 2.5 drinks (SD = 2.8) per night yet consumed 3.8 drinks (SD = 3.9) on average. Drinking intentions were higher among those who frequently went out at night and engaged in more frequent predrinking. The number of drinks consumed before 8 pm, attending multiple locations, and being with larger groups of friends contributed to higher consumption for both men and women.
Abstract Objective The literature highlights the need to move beyond the traditional heavy episodic (“binge”) drinking criteria when trying to identify at-risk college drinkers. Thus, recent ...attention has focused on more extreme levels of drinking. This study examines whether drinking motives can distinguish college student extreme drinkers from lighter drinkers. Method We used data from 3518 college student current drinkers (63.4% women) who participated in eight different studies at five different college campuses across the United States; a subsample of these students was followed up at 6 months post-baseline. At baseline and follow-up, drinkers were divided into three groups: nonbinge drinkers (< 4 drinks for women and 5 for men on their maximum drinking occasion), binge drinkers (4–7 drinks for women; 5–9 for men), and extreme drinkers (8 + for women and 10 + for men). Results At baseline, extreme drinkers, compared to nonbinge and binge drinkers, reported greater social, enhancement, and coping motives, as well as greater quantity and frequency of drinking per week and more alcohol-related problems. Those who were not extreme drinkers at baseline and later became extreme drinkers at follow-up reported significantly greater increases in social and enhancement motives, compared to those who remained nonextreme drinkers. Those who were extreme drinkers at baseline and reduced their drinking 6 months later, compared to those who remained extreme drinkers, reported greater reductions in enhancement and coping motives. Conclusions Focusing on drinking motives might be an efficacious target for preventive intervention programs to reduce extreme drinking among college students.
Alcohol consumption estimates in public health predominantly rely on self-reported survey data which is likely to underestimate consumption volume. Surveys tend to ask specifically about standard ...drinks and provide a definition or guide in an effort to gather accurate estimates. This study aimed to investigate whether the inclusion of the term standard drinks with pictorial guide is associated with an adjustment in self-reported alcohol volume.
A web-based survey was administered with AUDIT-C questions repeated at the beginning and end of the survey with and without the standard drink term and guide. The order in which respondents were presented with the different question types was randomised. Two cohorts of university/college students in NSW Australia (n = 122) and the US Pacific Northwest (n = 285) completed the survey online.
Australian students did not adjust their responses to questions with and without the standard drink term and pictorial guide. The US students were more likely to adjust their responses based on the detail of the question asked. Those US students who drank more frequently and in greater volume were less likely to adjust/apply a conversion to their consumption.
This study supports previous findings of the inaccuracy of alcohol consumption volume in surveys, but also demonstrates that an assumption of underestimation cannot be applied to all individual reports of consumption. Using additional questions to better understand drink types and serving sizes is a potential approach to enable accurate calculation of underestimation in survey data.

Alcohol use during adolescence has been predicted by motives to drink or abstain, as well as parental attitudes to youth drinking. As peers can provide access and opportunities to drink, ...permissiveness of peers' parents toward alcohol is also of importance.
We examined whether adolescent alcohol use is predicted by motives to drink or abstain, strictness of one's own parents, alcohol permissiveness by peers' parents, and an interaction between these factors.
A sample of high school students from the Pacific Northwest (N = 1056; 49% girls; m
age
= 15.6) completed alcohol use and parenting measures, the Drinking Motives Questionnaire-Revised, and the Motives for Abstaining from Alcohol Questionnaire. A zero-inflated negative binomial regression model examined the combined influence of motives, parent's strictness, and peer's parents' permissiveness on past month use.
Parental permissiveness was associated with higher rates of drinking among students with low (but not high) conformity motives and motives to abstain. Higher parental permissiveness was associated with higher rates of drinking among students with low (but not high) coping motives.
Our results demonstrate that parental strictness regarding teen alcohol use extends beyond the family unit to influence adolescent drinking in the broader social network. Parents may have a limited capacity to deter drinking through setting rules and expectations for adolescents who are motived to drink to conform but such limit setting maybe particularly helpful for youth with fewer motives to abstain.

•Identifying frequency as the most important predictor variable in these social smoking models has significant implications for future research and prevention.•While smoking frequency most ...consistently predicted social smoking classifications, the relative importance of other predictors varied across social smoking definitions.•Based on these findings, the a more simple definition of social smoking is recommended for future research.•Using a definition that considers social smoking as those who only smoke with others does not allow any room for interpretation for participants, ensuring that heavy non-social smokers will not self-select into the social smoking group.
Idiosyncratic definitions of social smoking proliferate in the literature, making cross-study comparison challenging. This project investigated and differentiated four distinct classifications of social smoking using traditional modeling techniques as well as a multilayer perceptron artificial network, a novel machine learning approach suited for heterogeneous, multidimensional data.
One hundred thirty-three adults recruited from a college in the Pacific Northwest and from Amazon Mechanical Turk, age 18 to 25 (48% men; 37% women; 8% nonbinary; 73% white; 24% Hispanic or Latinx), completed a set of self-report measures assessing common variables associated with cigarette use. Participants also completed a well-validated audio simulation (Smoking-Simulated Intoxication Digital Elicitation) depicting social smoking contexts and reported their willingness to use cigarettes or alcohol in these contexts.
Across three of the four social smoking definitions, social smokers consistently scored lower on measures of dependence, frequency, quantity, willingness to smoke, and all use motives than nonsocial smokers. The area under the curve for all four models ranged from excellent to outstanding discrimination within the training set. Frequency of days smoked in the past month was the most important predictor for three of the classification models with a relative importance of 100%.
The social smoking definitions demonstrated great variability across common cigarette use variables between groups, except for one. The machine learning approach successfully differentiated all four classifications. Recommendations are made for which social smoker classifications to use in subsequent research to maximize appropriate endorsement by the target population.
Social anxiety is often purported to be a risk factor for increased cannabis use. Cannabis use motives are strong explanatory predictors of cannabis use embedded within social contexts. This ...investigation explored the impact of social anxiety, cannabis motives, and their interaction on willingness to use cannabis in a community sample of emerging adults. Social anxiety was anticipated to positively correlate with coping and conformity motives and greater willingness to use cannabis in peer social contexts. Motives to use were hypothesized to potentiate social anxiety’s influence on cannabis use decision-making. In total, 124 participants completed an audio simulation of social cannabis use contexts (Can-SIDE) and standard measures of social anxiety (SIAS) and use motives (MMM). Contrary to expectations, social anxiety exerted a protective effect on willingness to use cannabis, but only when conformity, social, and expansion motives were at or below average. These effects varied by social contexts of use. Social anxiety leading to increased cannabis use may be most apparent in clinical samples and in high-risk cannabis users, but this pattern was not supported in this sample of community living emerging adults below clinical cutoffs for cannabis use disorder with relatively high social anxiety.
Abstract
Aims
Emerging adulthood (ages 18–25) has been associated with elevated alcohol use, yet little is known regarding gender identity and drinking contexts in this population. Our goals were to ...examine the effects of perceived gender match on alcohol use decision-making in social settings among emerging adults.
Methods
Participants (N = 135; 64% white, 11 transgender) completed measures of alcohol consumption, alcohol expectancies and motives, and the Collegiate-Simulated Intoxication Digital Elicitation using an established Internet panel. We conducted a series of univariate analyses to examine the relation between perceived gender match and behavioral willingness (BW) to accept alcohol in a social context.
Results
Participants identifying as men were significantly more likely to accept offers of alcohol when compared with women. While men and women did not differ in terms of BW when participants perceived a gender-matched actor making the offer, when there was a gender mismatch, women had significantly lower BW when compared with men. Though transgender participants were more likely to endorse hazardous drinking behaviors, there were no observable effects of transgender identity on BW.
Conclusion
In this sample, we found that men have a higher BW for alcohol than women and that trans identified persons are at increased risk for alcohol misuse. These findings support the need for more research examining the effect of gender identity on patterns of alcohol use and decision-making in mixed-gender contexts for emerging adults.
Background
Adolescent selective intervention programs for alcohol have focused on the identification of youth at risk as a function of personality and associated alcohol‐related cognitions. Research ...into the role of personality, drinking motivations, and alcohol‐related outcomes has generally focused exclusively on motives to drink. We expand on this literature by focusing on both motives to drink and motives not to drink across time from adolescence to early adulthood in a community sample.
Methods
Using 3 waves of data from 3 cohorts from the Rutgers Health and Human Development Project (n = 1,380; 49.4% women), we modeled the influence of baseline alcohol consumption, disinhibition (DIS), and harm avoidance (ages 15, 18, and 21 years) on drinking motives and motives not to drink 3 years later (ages 18, 21, and 24 years) and alcohol use and drinking‐related problems 7 years subsequently (ages 25, 28, and 31 years).
Results
Path analytic models were relatively invariant across cohort. Across cohorts, DIS and baseline alcohol consumption related to later positive reinforcement drinking motives, but less consistency was found for the prediction of negative reinforcement motives to drink. While positive reinforcement motives were associated with greater alcohol consumption and problems 7 years later, negative reinforcement motives were generally associated with problems alone. Positive reinforcement motives for drinking mediated relations between baseline consumption and later consumption. However, results were mixed when considering DIS as a predictor and drinking problems as an outcome. Similarly, personality and baseline consumption related to later motives not to drink and such motives predicted subsequent alcohol‐related problems. However, mediation was not generally supported for pathways through motives to abstain.
Conclusions
The results of this study replicate and extend previous longitudinal findings with youth and add to the growing literature on motivations not to engage in alcohol use.
This study used a person-centered approach to identify naturally occurring combinations of intrinsic motivation and controlled forms of extrinsic motivation (i.e., introjected and external ...regulation) and their correlates in an academic context. 1061 high school students completed measures of academic motivation, performance, and school-related correlates. Cluster analysis revealed four motivational profiles characterized by comparably high levels of all types of motivation (high quantity), high intrinsic motivation relative to introjected and external regulation (good quality), low intrinsic motivation and introjected regulation relative to external regulation (poor quality), and very low intrinsic motivation and introjected regulation relative to external regulation (low quantity with poor quality). Students in the high quantity and good quality profiles reported the strongest academic performance and greatest overall extracurricular participation, with students in different motivational profiles likely to participate in different types of activities. Students in the high quantity profile, moreover, perceived the most teacher support and school relatedness. These findings suggest that controlled forms of extrinsic motivation may not be associated with maladaptive outcomes at the high school level when coupled with high levels of intrinsic motivation.
► Examined profiles of intrinsic and extrinsic motivation in high school students. ► Four profiles: high quantity, good quality, poor quality, low quantity. ► High quantity and good quality profiles associated with highest performance. ► High quantity and good quality profiles most involved with extracurriculars. ► High quantity associated with greatest teacher support and school relatedness.
