  1. Article ; Online: First Comes Substance Use, Then Comes Social Media Posts? Examining the Temporal Ordering and Relative Strength of Relations Across Alcohol, Tobacco and Marijuana Use and Posting Behavior.

    Abstract Social media posts represent a major route by which youth share their substance use cognitions and experiences with others. Extant research has primarily examined relations between alcohol-related posts and posters' own alcohol use, yet little is known about the role of social media in the use of less socially accepted substances, namely tobacco and marijuana. Our study represents the first to examine the relative strength of this relation across alcohol, tobacco, and marijuana. The current research used a one-month time lag to tease apart the temporal ordering of substance-use-posting and participants' own substance use. A sample of 282 15-20-year-olds (Mage = 18.4, SD = 1.3, 52.9% female) in the United States completed two self-report surveys, one month apart. Results of a cross-lagged panel model revealed significant effects of alcohol and marijuana consumption on subsequent alcohol- and marijuana-related posting, respectively (i.e., selection effects). However, reverse relations (i.e., self-effects) were not significant. Further, we found no differences in the strength of selection effects across substances, suggesting they are similar for both more (alcohol) and less (marijuana and tobacco) socially acceptable substances. Results point to the importance of using young people's social media posts as a way to help identify individuals at risk for heightened substance use and social media as a mechanism for targeted prevention programming.

    Abstract The outbreak of the COVID-19 virus dramatically changed daily life and created many obstacles for adolescents to engage in physical activity (PA). This study tracked rates of self-reported PA and examined its impact on adjustment among adolescents during the first 14 months of the pandemic. Canadian adolescents (N = 1068, 14-18 y, meanage = 16.95 y) reported on their frequency of PA, context of activity, and adjustment across 4 time points (April 2020 to June 2021). In line with our hypothesis, higher average levels of vigorous PA across the pandemic predicted less anxiety and depression and higher self-esteem at our study's end. Vigorous PA also buffered the relationships COVID-19 stress had with anxiety and self-esteem. The results further support recommendations for PA throughout the pandemic and while dealing with lockdown situations.

    Abstract The COVID-19 pandemic notably altered adolescent substance use during the initial stage (Spring 2020) of the pandemic. The purpose of this longitudinal study is to examine trajectories of adolescent substance use across the pandemic and subsequent periods of stay-at-home orders and re-opening efforts. We further examined differences as a function of current high school student versus graduate status. Adolescents (n = 1068, 14-18 years, M

  5. Article ; Online: What Does Adolescent Substance Use Look Like During the COVID-19 Pandemic? Examining Changes in Frequency, Social Contexts, and Pandemic-Related Predictors.

    Dumas, Tara M / Ellis, Wendy / Litt, Dana M

    Abstract Purpose: The overarching goal of this study was to provide key information on how adolescents' substance use has changed since the corona virus disease (COVID)-19 pandemic, in addition to key contexts and correlates of substance use during social distancing.
    Methods: Canadian adolescents (n = 1,054, M
    Results: For most substances, the percentage of users decreased; however, the frequency of both alcohol and cannabis use increased. Although the greatest percentage of adolescents was engaging in solitary substance use (49.3%), many were still using substances with peers via technology (31.6%) and, shockingly, even face to face (23.6%). Concerns for how social distancing would affect peer reputation was a significant predictor of face-to-face substance use with friends among adolescents with low self-reported popularity, and a significant predictor of solitary substance use among average and high popularity teens. Finally, adjustment predictors, including depression and fear of the infectivity of COVID-19, predicted using solitary substance use during the pandemic.
    Conclusions: Our results provide preliminary evidence that adolescent substance use, including that which occurs face to face with peers, thereby putting adolescents at risk for contracting COVID-19, may be of particular concern during the pandemic. Further, solitary adolescent substance use during the pandemic, which is associated with poorer mental health and coping, may also be a notable concern worthy of further investigation.

    Abstract Background: Sexual aggression (SA) is ubiquitous in drinking environments. Although such behavior is often seen as normal and acceptable, the targets of SA experience many negative consequences. This research aimed to develop a valid measure of common acts of SA in drinking settings for estimating prevalence and evaluating prevention initiatives.
    Methods: We developed a questionnaire measure of common acts of sexual harassment and aggression in drinking environments (C-SHADE) based on descriptions of SA behavior from our own and others' research. The measure was validated in a cross-sectional survey of 335 men aged 19 to 25 using webpanels from an online survey company. Validation measures included: a modified version of the Sexual Experiences Survey (M-SES), measures of SA by peers in drinking environments, SA-related attitudes, expectancies about sexual effects of alcohol, and alcohol consumption.
    Results: The C-SHADE showed high internal consistency (α = 0.96) and was significantly correlated with M-SES (r = 0.52), SA by peers (r = 0.61 to 0.70), SA-related attitudes/expectations (r = 0.38 to 0.55), and measures of alcohol consumption (r = 0.22 to 0.36). Overall, 71.9% of participants reported SA using the C-SHADE versus 24.7% with the M-SES. We compared the responses of participants who reported perpetration on both measures (N = 83), on only the C-SHADE (N = 141), and among nonperpetrators (N = 89; excluding four participants who reported perpetration only on the M-SES). The M-SES/C-SHADE perpetrators scored significantly higher than C-SHADE-only perpetrators and nonperpetrators on most SA-related and drinking measures, while C-SHADE-only perpetrators scored significantly higher than nonperpetrators on peer SA and two attitude measures.
    Conclusions: The C-SHADE is suitable for measuring prevalence and evaluating interventions in drinking settings. The C-SHADE confirmed a high prevalence of SA in drinking settings and identified an important group of C-SHADE-only perpetrators for whom interventions that focus on situational precipitators of SA in drinking settings may be especially useful.
