Description
Alcohol use remains a large part of collegiate life and is a major public health concern. Alcohol use generally peaks during the early twenties and declines with age. These declines, referred to as "maturing out," are presumed to be the result of the acquisition of adult roles (e.g. marriage, parenthood, employment) incompatible with alcohol use. Recent empirical evidence suggests that variables other than role transitions (e.g. personality) during emerging adulthood may also be important in understanding this process. Conceptually, changes in identity that occur during emerging adulthood may also be linked to the process of maturing out of heavy drinking, though no studies have yet addressed this possibility. Utilizing data from a large sample of graduating college students during senior year and the two following years (N = 907), the current study examined relations between aspects of emerging adult identity development (identity exploration, instability, self-focus, feeling in-between, and experimentation/possibilities) and drinking outcomes (alcohol use and problems). Using multiple regression, changes in emerging adult identity development accounted for significant variability in alcohol use over and above relationship and employment status. Decreases in experimentation/possibilities significantly predicted decreases in alcohol use. Conversely, increases in feeling in-between significantly predicted decreases in alcohol use. The findings have important implications for both theories of "maturing out" and the development of prevention and early intervention efforts targeting alcohol abuse during this high-risk developmental period.

Description
Motor behavior is prone to variable conditions and deviates further in disorders affecting the nervous system. A combination of environmental and neural factors impacts the amount of uncertainty. Although the influence of these factors on estimating endpoint positions have been examined, the role of limb configuration on endpoint variability has been mostly ignored. Characterizing the influence of arm configuration (i.e. intrinsic factors) would allow greater comprehension of sensorimotor integration and assist in interpreting exaggerated movement variability in patients. In this study, subjects were placed in a 3-D virtual reality environment and were asked to move from a starting position to one of three targets in the frontal plane with and without visual feedback of the moving limb. The alternating of visual feedback during trials increased uncertainty between the planning and execution phases. The starting limb configurations, adducted and abducted, were varied in separate blocks. Arm configurations were setup by rotating along the shoulder-hand axis to maintain endpoint position. The investigation hypothesized: 1) patterns of endpoint variability of movements would be dependent upon the starting arm configuration and 2) any differences observed would be more apparent in conditions that withheld visual feedback. The results indicated that there were differences in endpoint variability between arm configurations in both visual conditions, but differences in variability increased when visual feedback was withheld. Overall this suggests that in the presence of visual feedback, planning of movements in 3D space mostly uses coordinates that are arm configuration independent. On the other hand, without visual feedback, planning of movements in 3D space relies substantially on intrinsic coordinates.

Description
Individuals with strong broad social motives (BSM) place high personal value on social activities and are at increased risk for heavy drinking. Those with strong BSM who also perceive that college students are heavy drinkers (high descriptive norms) might be particularly susceptible to increases in alcohol use during the transition to college, and may be likely to drink for social facilitation (social drinking motives). To test these hypotheses, we examined a mediated moderation model testing interactive effects of BSM and descriptive norms (perceptions of drinking in college) on drinking behavior, mediated by social drinking motives. Data were from 426 incoming college students and analyses were based on a subsample of 218 who reported drinking behavior at either time point. Results indicated that BSM interacted with descriptive norms to predict increases in social drinking motives from high school to college and social drinking motives in turn predicted increases in alcohol use. Probing this interaction revealed that those with high BSM and high descriptive norms experienced greater increases in social drinking motives than those with low descriptive norms. Tests of moderated indirect effects indicated that effects of BSM on drinking behavior through social drinking motives were also stronger among those with high descriptive norms. These results identify a particularly high risk group for changes in alcohol use during an important developmental period. This may have important implications for prevention and intervention methods which can attenuate college alcohol use by targeting individuals with strong BSM who perceive heavy drinking among college peers.

Description
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.

Description
This study examined the cross-sectional and longitudinal associations among diurnal cortisol rhythms and sleeping patterns in adolescents. 79 participants completed the study over three days during the spring semester of their senior year in high school, and 76 of these subjects participated again over three days during the fall semester of their freshman year in college. They completed daily saliva samples and diary entries, while wearing an actigraph to obtain objective measurements of sleep duration and efficiency. Cross-sectionally, longer sleep duration was associated with a lower cortisol awakening response, a smaller area under the cortisol curve, and a steeper cortisol slope. Longitudinally, there was no significant relationship between sleep duration and these cortisol parameters. Moreover, sleep efficiency was not associated with cortisol parameters cross-sectionally nor longitudinally. Results suggest associations between concurrent sleep duration and cortisol patterns, and may have significant impact on understanding adolescents' physiological response to stress.

Description
The COVID-19 pandemic has generated alarming increases in psychological distress and alcohol use behaviors and has caused the greatest increases in depression and anxiety symptoms among college students. Prior studies have examined the impact of COVID-19 broadly on mental health and alcohol use outcomes; however, few studies have examined these impacts in college students. Previous studies have examined individual factors that could moderate the relation between COVID-19 related stressors and mental health and alcohol use outcomes, but knowledge is lacking regarding the role of emotion regulation. The present study aimed to examine the role of emotion regulation in the relation between both COVID-19 stressful experiences and COVID-19 related worry and mental health and alcohol use outcomes, and to explore racial/ethnic differences in their associations. Four hierarchical multiple regression models were conducted to assess main effects of COVID-19 stressors and emotion regulation, as well as moderation of the effect of emotion regulation on depression symptoms, anxiety symptoms, alcohol consumption, and alcohol use disorder (AUD) symptoms during the past year. COVID-19 related worry was associated with greater symptoms of both mental health outcomes, whereas COVID-19 related stressful experiences were associated with both mental health outcomes, more alcohol consumption, and more AUD symptoms. Difficulties in emotion regulation had significant main effects on mental health outcomes and AUD symptoms, but not alcohol consumption. Hispanic/Latinx students reported higher experiences of both COVID-19 related stressors, but consumed less alcohol than did White/European students. This study provides further insight into the nature of COVID-19 related stressors and their subsequent impacts. Implications for prevention and intervention on college campuses are discussed.
