Increased coping motives during the COVID-19 pandemic widen cannabis disparities between sexual minoritized and nonminoritized young adults: A bimonthly assessment of data preceding and spanning the pandemic.

OBJECTIVE: Since the start of the coronavirus pandemic, some U.S. adults have increased alcohol and cannabis use frequency to cope with distress. Among sexual minoritized young adults (SM YAs), coping-related use may be greater due to disproportionate negative social and financial consequences of the pandemic. Nonetheless, it remains unclear whether pandemic substance use has increased among SM YAs compared to non-SM YAs relative to prepandemic levels and whether heightened coping motives mediate these potential differences. METHOD: A total of 563 YAs (18-24 years at baseline; 31.0% SM) provided survey data collected across 12 bimonthly assessments. Six assessments were measured in 2015 or 2016 and six across the coronavirus pandemic (2020-2021). Controlling for prepandemic assessments matched by calendar month, latent structural equation models examined group differences in alcohol and cannabis frequency and consequences across the COVID-19 period and tested coping motives as mediators of these differences. RESULTS: Substance use and consequences were similar during the pandemic relative to prepandemic levels across groups. Nonetheless, compared to non-SM individuals, SM participants reported greater cannabis frequency, consequences, and cannabis coping motives during the pandemic independent of prepandemic levels. Cannabis use and consequences were each explained largely by coping motives during the pandemic among SM compared to non-SM YAs. These patterns were not found for alcohol outcomes. CONCLUSIONS: The COVID-19 pandemic has widened cannabis disparities between SM and non-SM YAs, due in part to pandemic-related increases in coping motives. Responsive public policy is needed that may prevent and remit SM cannabis disparities during societal crises. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Trends in Young Adult Alcohol and Cannabis Use through the First Year and a Half of the COVID-19 Pandemic from a Community Cohort Sample.

OBJECTIVE: There has been concern regarding increased substance use during the COVID-19 pandemic, particularly among young adults, but much of this concern stemmed from cross-sectional or short-term data collected early in the pandemic. This study followed a young adult community cohort throughout the first year and a half of the pandemic to examine longer-term trends/trajectories in alcohol and cannabis use behaviors. METHOD: Beginning prior to the COVID-19 pandemic (January 2020), 656 young adults completed up to 8 surveys on substance use and other behaviors, which extended through August 2021. Multilevel spline growth models estimated changes in alcohol/cannabis use in three segments: (1) from pre-pandemic to April 2020, (2) from April 2020 to September/October 2020, and (3) from September/October 2020 to July/August 2021. Abstainers were removed from analyses, yielding subsamples for alcohol models (N=545; Mage=25.6; 59.8% female) and cannabis models (N=303; Mage=25.6; 61.4% female). RESULTS: Drinking frequency initially increased (3% per month), decreased in the second segment (4% per month), and plateaued in the final segment. Drinking quantity significantly decreased in all three segments: 4% per month in segment one, 3% per month in segment two, and 1% per month in the final segment. Cannabis frequency and quantity showed no significant changes across the first two segments, then significantly decreased in the final segment (3% and 6% per month, respectively). The significant changes for cannabis frequency/quantity were moderated by age, such that older participants had steeper decreases in the final segment. CONCLUSIONS: Findings highlight that young adult alcohol and cannabis use generally declined across the first year and a half of the COVID-19 pandemic, contrary to widespread concerns.

Alcohol and marijuana use predicting next-day absenteeism and engagement at school and work: A daily study of young adults.

This study examined effects of alcohol and marijuana use on next-day absenteeism and engagement at work and school among young adults (18-25 years old) who reported past-month alcohol use and simultaneous alcohol and marijuana use. Participants completed twice daily surveys for five, 14-day bursts. The analytic sample was 409 [64 % were enrolled in university (N = 263) and 95 % were employed (N = 387) in at least one burst]. Daily measures included: any alcohol or marijuana use, quantity of alcohol or marijuana use (i.e., number of drinks, number of hours high), attendance at work or school, and engagement (i.e., attentiveness, productivity) at school or work. Multilevel models examined between- and within-person associations between alcohol and marijuana use and next-day absenteeism and engagement at school or work. Between-persons, the proportion of days of alcohol use days was positively associated with next-day absence from school, consuming more drinks was positively associated with next-day absence from work, and the proportion of days of marijuana use was positively associated with next-day engagement at work. At the daily-level, when individuals consumed any alcohol and when they consumed more drinks than average, they reported lower next-day engagement during school and work. When individuals used marijuana and when they were high for more hours than average, they reported lower next-day engagement during school. Findings suggest alcohol and marijuana use consequences include next-day absence and decrements in next-day engagement at school and work, which could be included in interventions aimed at ameliorating harmful impacts of substance use among young adults.

The effects of alcohol and marijuana co-use patterns on intimate partner aggression perpetration.

Alcohol and marijuana are two of the most widely used substances in the U.S, with rates of alcohol and marijuana co-use increasing in recent years. Despite this increase, little is known about the effects of alcohol and marijuana co-use patterns (e.g., simultaneous, concurrent) on intimate partner aggression (IPA) perpetration. The purpose of the current study was to examine differences in IPA among simultaneous and concurrent alcohol and marijuana use groups and an alcohol-only group. Participants were 496 individuals (57% identifying as a woman) recruited nationally in April 2020 via Qualtrics Research Services who reported being in a current relationship and recently consuming alcohol. Individuals completed an online survey that included demographics, measures of COVID-19 stress, alcohol and marijuana use, and physical and psychological IPA perpetration. Based on survey responses, individuals were categorized as belonging to the alcohol use only group (n = 300), the concurrent alcohol and marijuana use group (n = 129), or the regular simultaneous alcohol and marijuana use group (n = 67). Due to inclusion criteria, there was no marijuana use only group. Individuals with regular simultaneous or concurrent alcohol and marijuana co-use reported more frequent physical and psychological IPA perpetration compared to those who only used alcohol. Neither physical nor psychological IPA perpetration frequency differed between individuals who reported regular simultaneous versus concurrent alcohol and marijuana co-use. Results suggest that alcohol and marijuana co-use in general, and not the specific pattern of use, is associated with an increased likelihood of IPA perpetration.

Trajectories of loneliness during COVID-19 pandemic and associations with mental health and substance use.

We examined patterns of longitudinal trajectories of loneliness during the COVID-19 pandemic using six time points (January 2020 [pre-pandemic] to March/April 2021) and whether trajectories were associated with psychological distress (depression/anxiety) and substance use (alcohol/cannabis) outcomes in Spring 2021. Participants were 644 young adults who completed online assessments. Outcomes were regressed on most-likely loneliness trajectory adjusting for pre-pandemic measures. Three loneliness trajectories varied from consistently lower to consistently higher. Pre-pandemic social support was associated with lower odds of a higher loneliness trajectory. Higher loneliness trajectories were associated with greater odds of past-month cannabis use compared to Low trajectories, but not significantly associated with depression, anxiety, or alcohol use in Spring 2021. Interventions addressing co-occurring loneliness and cannabis use are needed.

Multifaceted COVID-19-Related Stressors and Associations with Indices of Mental Health, Well-being, and Substance Use Among Young Adults.

Alongside direct health concerns pertaining to the SARS-CoV-2 virus, the stressors and life disruptions associated with the COVID-19 pandemic may provoke secondary concerns for health and well-being. The implications of COVID-19-related stressors may be particularly salient for young adults, who are at higher-risk for mental health concerns and substance use behaviors. We developed a multifaceted scale that assessed distinct domains of COVID-19-related stressors and examined associations between these stressors and indices of mental health, well-being, and substance use (alcohol and marijuana use). In April-June of 2020, 1181 young adults were recruited from two- and four-year colleges to participate in this study (M age = 20.40; 59.95% women). Exploratory factor analysis identified five domains of COVID-19-related stressors: job insecurity, social/relational, financial, illness-related, and school-related. The overall pattern of results indicated that COVID-19-related stressors were related to poorer mental health and well-being. Social/relational stressors emerged as a primary concern most strongly associated with indices of mental health and alcohol use, relative to other stressors. However, illness-related stressors and school-related stressors were associated with less alcohol use. Stressors associated with the COVID-19 pandemic may impact young adults' health and well-being but disentangling various stressor domains informs more tailored intervention and prevention strategies.

Mental Health and Well-Being Trends Through the First Year-and-a-Half of the COVID-19 Pandemic: Results from a Longitudinal Study of Young Adults in the USA.

This study examined longitudinal trajectories of young adults' mental health and well-being before and throughout the first year-and-a-half of the COVID-19 pandemic. Repeated assessments of a young adult community cohort (N = 656; Mage = 25.6 years; 59.3% female) were conducted beginning prior to COVID-19 (January 2020) and extending through August 2021. Multilevel spline growth models estimated changes in three segments: (a) from pre-pandemic to April/May 2020, (b) from April/May 2020 to September 2020, and (c) from September 2020 to August 2021. Depression symptoms and loneliness increased significantly in the first segment, plateaued slightly, then decreased significantly across the final segment. Anxiety symptoms were unchanged across the first two segments, but significantly decreased in the final segment. Satisfaction with life decreased significantly across the first two segments, and then increased significantly in the final segment. Direct comparisons of pre-pandemic scores (January 2020) to the last follow-up (July or August 2021) showed a return to pre-pandemic levels of depression symptoms, loneliness, and satisfaction with life, as indicated by non-significant differences, and significantly lower anxiety symptoms, relative to pre-pandemic. Findings support concerns for young adults' mental health and well-being in the initial months of the COVID-19 pandemic, but also indicate that young adults' emotional well-being, on average, may be returning to pre-pandemic levels.

Longitudinal effects of COVID-19-related stressors on young adults' mental health and wellbeing.

The COVID-19 pandemic has presented young adults with novel challenges and disruptions to several life domains. The current study examined how COVID-19-related stressors (i.e., job-related, financial-related, social/relational, and illness-related stressors) relate to young adults' symptoms of depression and anxiety, and satisfaction with life (in the US). In Aim 1, we examined associations between COVID-19-related stressors and indices of mental health and well-being in the initial phase of the pandemic (April/May 2020) while accounting for participants' pre-pandemic levels of these outcomes in January of 2020 (N = 519; Mage = 25.4; 62.8% women). Social/relational stressors were most strongly associated with increased symptoms of anxiety/depression, and financial stressors were most strongly associated with decreased satisfaction with life. Extending this research longitudinally (Aim 2), we sampled young adults bi-monthly across a year-long period (September 2020 to August 2021). Multilevel models revealed within-person associations between each stressor domain and mental health/well-being; young adults reported more symptoms of depression/anxiety and lower satisfaction with life in months that stressors were relatively more salient. Interactions between stressors and time revealed associations were generally stronger in earlier months and decreased linearly across the pandemic. Taken together, longitudinal evidence indicates that COVID-19-related stressors, especially social/relational stressors, have direct and time-varying associations with mental health and well-being.

Effect of COVID-19 Anthropause on Water Clarity in the Belize Coastal Lagoon

The COVID-19 pandemic halted human activities globally in multiple sectors including tourism. As a result, nations with heavy tourism, such as Belize, experienced improvements in water quality. Remote sensing technologies can detect impacts of “anthropauses” on coastal water quality. In this study, MODIS satellite data were employed along the Belizean coast to investigate impacts of the COVID-19 shutdown on water quality. The attenuation coefficient at 490 nm, Kd(490), was used as an indicator of water quality, with a lower Kd(490) indicating increased water clarity. Four Coastal Management Zones were characterized by marine traffic as high traffic areas (HTAs) and two as low traffic areas (LTAs). Monthly composites for two periods, 2002-2019 (baseline) and 2020 were examined for Kd(490). For months prior to the COVID-19 shutdown in Belize, there was generally no significant difference in Kd(490) (p>0.05) between 2020 and baseline period in HTAs and LTAs. Through the shutdown, Kd was lower in 2020 at HTAs, but not for LTAs. At the LTAs, the Kd(490)s observed in 2020 were similar to previous years through October. In November, an unusually active hurricane season in 2020 was associated with decreased water clarity along the entire coast of Belize. This study provides proof of concept that satellite-based monitoring of water quality can complement in situ data and provide evidence of significant water quality improvements due to the COVID-19 shutdown, likely due to reduced marine traffic. However, these improvements were no longer observed following an active hurricane season.

Young Adults Underestimate How Well Peers Adhere to COVID-19 Preventive Behavioral Guidelines.

To combat the rampant spread of the SARS-CoV-2 virus that is responsible for the COVID-19 pandemic, the Centers for Disease Control and Prevention (CDC) has provided Americans with empirically supported preventive behavioral guidelines (e.g., wearing a face mask). However, there is a need to develop behavioral strategies that can effectively increase adherence to these guidelines, especially for young adults, who report particularly poor adherence. Across several domains of prevention science, norms-based interventions have successfully motivated constructive health behavior by correcting normative misperceptions, but these strategies are only relevant when these misperceptions are widespread. We examined the accuracy of young adults' perceptions of peers' adherence to CDC-recommended behavioral guidelines (i.e., perceived social norms) to assess the rationale for employing norm-correcting strategies. Young adult college students (N = 539; Mage = 19.5 years) self-reported their level of adherence to a list of preventive behavioral guidelines and estimated the norms regarding the extent to which other young adults adhered to these guidelines. We measured adherence and perceived norms for each guideline in terms of adherence frequency, ranging from 0 to 100% of the time. We found that young adults, on average, underestimated the extent to which other young adults adhere to each of the recommended preventive behaviors. That is, young adults tended to think that other young adults are failing to adhere to CDC guidelines, whereas our self-reported data showed adherence frequency may be quite high. Moreover, we found positive associations between self-reported adherence and perceptions of others' adherence-that is, those who underestimated others' adherence also self-reported lower adherence to guidelines. Findings from this study establish proof-of-concept for the development of norms-based strategies designed to improve young adults' adherence to preventive behavioral guidelines that are both specific to the COVID-19 pandemic and that prepare for future contagious outbreaks.

Young adults' physical distancing behaviors during the initial months of the COVID-19 pandemic: Adherence to guidelines and associations with alcohol use behavior.

Throughout the COVID-19 pandemic, the scientific and public health communities have become increasingly focused on understanding young adults' physical distancing behaviors and the role that young adults have on viral potentiation and community spread. In the present study, we surveyed a group of 560 young adults (ages 22-28) from the greater Seattle area in April 2020, during statewide "shelter-in-place" recommendations, to examine young adults' self-reported adherence to physical distancing guidelines. Self-report measures were used to identify strong adherers and poor adherers, which we then compared in terms of engagement in specific physical distancing behaviors and alcohol use behaviors pertaining to physical distancing adherence. We found that most young adults are classified as strong adherers, and that poor adherers reported more frequent violations of physical distancing guidelines including having friends over to their residence or going over to other residences. Poor adherers were also significantly more likely to engage in high-risk alcohol use behavior, such as heavy episodic drinking, compared to those young adults who were classified as strong adherers. Our results provide initial evidence that young adults who engage in high-risk drinking may be at greater risk for non-adherence to government recommended physical distancing guidelines. This deeper understanding of young adult behavior during the COVID-19 pandemic can better inform public health outreach to increase physical distancing adherence currently, as well as in preparation for future contagious health crises that may require societal-level adherence to behavioral guidelines.

Changes in Young Adults' Alcohol and Marijuana Use, Norms, and Motives From Before to During the COVID-19 Pandemic.

PURPOSE: Alongside the SARS-CoV-2 virus, the COVID-19 pandemic is associated with several secondary health effects. There is concern for increased substance use motivated by coping with stress, anxiety, depression, and boredom-all of which may be elevated during the pandemic. The current study examined intraindividual changes (from pre-COVID to during COVID) in young adults' alcohol and marijuana use, perceptions of peers' use (i.e., norms), and motives for use. METHODS: A community sample of young adults (N = 572; Mage= 25.14; 60.8% women) was recruited in Washington State. By using a repeated-measures design, data were collected prior to the COVID-19 pandemic (January 2020) and again during the initial acute phase of the pandemic (April/May of 2020). RESULTS: Young adults, on average, increased alcohol use frequency but decreased the amount consumed per drinking occasion. No changes in marijuana use were identified. Young adults (on average) perceived that peers had increased the frequency and total amount of alcohol use and perceived that peers were engaging in heavier marijuana use than prior to COVID-19. For alcohol use motives, there was a significant increase in depression coping motives and significant decreases in social, enhancement, and conformity motives. Boredom motives for marijuana use significantly increased, while celebration motives decreased. CONCLUSIONS: Using a prospective design with a sample initially recruited in Washington State, these data indicate that (a) young adults' patterns of alcohol use may have changed, (b) young adults tend to think that peers are engaging in heavier alcohol/marijuana use than before the pandemic, and (c) motives for using alcohol/marijuana may have changed during the pandemic.

Social norms and vaccine uptake: College students' COVID vaccination intentions, attitudes, and estimated peer norms and comparisons with influenza vaccine.

BACKGROUND: Vaccination may be critical to curtailing the spread of the SARS-CoV-2 virus responsible for the COVID-19 pandemic, but herd immunity can only be realized with high vaccination coverage. There is a need to identify empirically supported strategies to increase uptake, especially among young adults as this subpopulation has shown relatively poor adherence to physical distancing guidelines. Social norms - estimates of peers' behavior and attitudes - are robust predictors of health behaviors and norms-based intervention strategies may increase COVID vaccine uptake, once available. This study examined the extent that vaccination intentions and attitudes were associated with estimated social norms as an initial proof-of-concept test. METHOD: In November of 2020, 647 undergraduate students (46.21% response rate) completed online surveys in which they reported intentions to get COVID and influenza vaccines, perceived importance of these vaccines for young adults, and estimated social norms regarding peers' vaccination behaviors and attitudes. RESULTS: Students reported significantly greater intentions to get a COVID vaccine (91.64%) than an influenza vaccine (76.04%), and perceived COVID vaccination as significantly more important than influenza vaccination. The sample generally held strong intentions to receive a COVID vaccine and thought that doing so was of high importance, but participants, on average, perceived that other young adults would be less likely to be vaccinated and would not think vaccination was as important. Multiple regression models indicated that estimated social norms were positively associated with participants' own intentions and perceived importance of getting a COVID vaccine. CONCLUSIONS: These significant associations highlight the potential value in developing and testing norms-based intervention strategies, such as personalized normative feedback, to improve uptake of forthcoming COVID vaccines among young adults.

Changes in college student alcohol use during the COVID-19 pandemic: Are perceived drinking norms still relevant?

With widespread concern for increased alcohol use during the COVID-19 pandemic, there is a pressing need to examine changes in young adults' alcohol use and to identify antecedents of increased use. We tested the hypothesis that self-reported changes in alcohol use during the pandemic (frequency, quantity, heavy episodic drinking) would relate to perceptions of peers' changes in alcohol use. In April of 2020, 507 college students self-reported changes in their alcohol use and perceived changes in use for typical students at their university (i.e., norms). Most students in our sample reported decreased alcohol use and perceived decreases in peers' alcohol use. Perceptions of peers' changes in alcohol use behavior strongly related to changes in students' own alcohol use. Findings provide strong support for norms-based strategies that can correct normative misperceptions by highlighting the fact that most college students are not in fact engaging in heavier alcohol use during the COVID-19 pandemic.

Increases in Loneliness Among Young Adults During the COVID-19 Pandemic and Association With Increases in Mental Health Problems.

PURPOSE: Young adults are at high risk for increases in loneliness and mental health problems during the COVID-19 pandemic. The present study examined increases in loneliness in a young adult sample, for whom increases were greater, and association with increases in depression and anxiety. METHOD: Data from 564 young adults (ages 22-29, 60.7% women) were collected in January 2020 (pre-pandemic) and April/May 2020 (during pandemic). RESULTS: Loneliness increased from January to April/May and changes in loneliness were greater for females, those with higher perceived social support in January, and those with greater concerns about the pandemic's social impacts. Depression (but not anxiety) increased during this time with changes in loneliness accounting for much of the increase in depression. CONCLUSIONS: Intervention strategies with young adults need to address loneliness and feelings of reduced social support during this time, especially for those who may have had greater disruption in their social lives.
