Abstract: 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 s le 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 s les and in high-risk cannabis users, but this pattern was not supported in this s le of community living emerging adults below clinical cutoffs for cannabis use disorder with relatively high social anxiety.

Abstract: 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 in idual and situational factors associated with a subsequent consumption over the course of multiple nights. 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 in idual-level and night-level factors associated with previous drinking intentions and subsequent deviations from intentions. 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 in idual and the night levels. Heavier consumption than intended also occurred when drinking away from home for men and when going to nightclubs for women. 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.

Abstract: This chapter discusses dual-process models of (health) behaviors, regarding both their recent criticisms and implications for health interventions. It agrees with critics that impulsive and reflective processes should not be equated with specific brain processes, but that psychological processes are emergent properties of the dynamic unfolding interplay between different neural systems. It maintains that at a psychological level of description, these models can still be useful to understand challenges to health behaviors and possible interventions. Affective processes can influence impulsive decision-making in health, but also reflective processes, when they concern affectively relevant goals. Cognitive training methods, including cognitive bias modification and training of executive control, have shown some success in changing health behaviors, but a critical variable for long-term success appears to be motivation to change.

Abstract: 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 in idual 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.
