Momentary effects of life stressors on mindfulness and emotion regulation difficulties among adolescents exposed to chronic stressors.

Adolescents faced with chronic stressors (e.g., financial instability, interpersonal violence) are at heightened risk for developing mental health problems, likely due in part to stressors that interfere with effective emotion regulation. Although mindfulness may help to act as a buffer against the deleterious effects of life stressors, a relatively untested assumption is that adolescents can maintain mindfulness during periods of stress. This paper explores this assumption by investigating the real-time, dynamic relationships among life stressors, mindfulness, and emotion regulation difficulties among adolescents exposed to chronic stressors. Eighty-one participants who were 10-18 years old (M = 14.33; SD = 2.20; 56% male; 57% Non-Hispanic White) completed ecological momentary assessments (EMA) three times a day for 7 days and contributed a total of 1186 EMA reports. Multilevel structural equation modelling revealed that the presence (vs. absence) of stressors was associated with lower momentary mindfulness and greater momentary emotion regulation difficulties concurrently and prospectively. Stressors with greater severity were also concurrently, but not prospectively, associated with lower momentary mindfulness and greater momentary emotion regulation difficulties. Findings highlight that exposure to life stressors may degrade momentary mindfulness and emotion regulation. Given that mindfulness and emotion regulation are closely associated with mental health, these results also demonstrate one way that stressors may contribute to health disparities at the micro-level. Going forward, it will be important to investigate methods of helping adolescents learn to maintain mindfulness and adaptive emotion regulation in the face of stressful events. This study was preregistered (NCT04927286).

Exploring perceptions of self-stigma of substance use and current alcohol and marijuana use patterns among college students.

BACKGROUND: While research has examined the effect of stigma from others towards individuals with substance use disorders, few studies have examined the relationship between perceived self-stigma and engagement in substance use more broadly, especially among non-clinical samples. AIMS: The present study examined the relationships between perceptions of self-stigma if one were to develop a substance use disorder, consisting of negative self-esteem and negative self-efficacy, and alcohol or marijuana use behaviors and outcomes. METHOD: Participants (n = 2,243; 71.5% female) were college students within the U.S. recruited to participate in an online survey on substance use with a special focus on alcohol and marijuana. RESULTS: Results indicated no significant differences in stigma scores across individuals with different lifetime alcohol and marijuana use. Stigma ratings did differ between individuals with different profiles of last 30-day alcohol and marijuana use where, generally, individuals with lifetime use but no use in the last 30-day reported higher levels of self-stigma. Correlation analyses indicated that perceived impact of substance use disorder on sense of self-efficacy and self-esteem related negatively to nearly all observed factors of alcohol and marijuana use. CONCLUSIONS: Though self-stigma, and stigma more broadly, has been shown to have negative implications for people with substance use disorders, the present study suggests that for non-clinical populations there may be some protective association between perceived self-stigma and alcohol or marijuana use engagement. This is not to say that self-stigma is a positive clinical intervention. Rather, we interpret these findings to indicate that negative perceptions of substance use disorder on the sense of self may be associated with distinct alcohol and marijuana use behaviors among young adults.

Development and Validation of the Positive Outcomes of Cannabis Use Scale (POCUS) Among Predominantly White Adults in the United States.

Operant conditioning and social learning theories suggest that positive cannabis use-related outcomes are a primary contributor to maintained use and risk for dependence. However, currently there does not exist a reliable, validated measure of positive cannabis-related outcomes. This study sought to develop and psychometrically evaluate the Positive Outcomes of Cannabis Use Scale (POCUS). We collected three samples, college students (N = 883), community adults (N = 214), and college students (N = 615), of predominantly White adults in the United States who completed an online survey. Exploratory and confirmatory factor analyses evaluated scale structure and identified four factors: social enhancement, mood enhancement, cognitive enhancement, and sexual enhancement. Positive outcomes were positively associated with recent use, controlling for expectancies and negative outcomes. Positive outcomes were also differentiated from positive expectancies and more influential in predicting typical use frequency. Findings indicate that the POCUS is psychometrically sound and clinically useful for measuring positive cannabis use-related outcomes among predominantly White adults in the United States.

A cross-sectional examination of race, gender, and intersectionality on protective behavioral strategies and alcohol outcomes among Black and White college students.

College students consistently report problematic alcohol use (e.g., excessive drinking). Protective behavioral strategies (PBS) are behaviors for reducing alcohol use and/or problems and are negatively associated with alcohol misuse among college students. Studies suggest PBS are used more often and/or more effectively by female individuals. Additionally, examinations specifically between Black and White students have yielded mixed findings and are typically underpowered. Scant studies have investigated the intersectionality between race and gender or examined perceived effectiveness of PBS use related to alcohol outcomes. The current cross-sectional study examined if (a) race, (b) gender, and (c) their interaction moderate the associations between perceived effectiveness of PBS use on PBS use (a path) and between PBS use on alcohol outcomes (i.e., alcohol quantity, peak drinks, and problems; b path). A sample size of N = 528 college drinkers ages 18-24 years old (Mage = 19.85; 52.5%, Black, 40.3% White) completed an online survey and were used for analyses. A series of moderated mediation models were conducted. Race did not moderate the a or b paths. The positive association for the a path as well as the indirect effect of PBS perceived effectiveness on lower alcohol outcomes through PBS use were stronger for female students than male students. The intersectionality examination indicated a stronger association between more PBS use and lower consumption, specifically for White male students, and lower problems for Black female students. More attention is needed toward considering intersectionality when identifying at-risk groups and tailoring alcohol intervention efforts.

Longitudinal examination of alcohol use motives, item-level protective behavioral strategies, and alcohol-related consequences.

BACKGROUND: Alcohol misuse among college students is a public health concern. Protective behavioral strategies (PBS) can be used before, during, after, or instead of drinking to reduce alcohol use and negative consequences, but findings on their utility at the aggregate level are mixed. Although recent work has provided important information on the performance of individual PBS items, it is limited by research designs that are cross-sectional, do not examine consequences, or do not examine other important correlates, such as drinking motives. This study examines both the association between item-level PBS and alcohol-related negative consequences and the moderating effect of drinking motives longitudinally. METHODS: College students from two universities (n = 200, 62.5% female, Mage = 20.16) completed the Drinking Motives Questionnaire-Revised, Protective Behavioral Strategies Survey, the Rutgers Alcohol Problem Index, and a measure of the quantity of alcohol use at baseline and 3-month follow-up. Generalized linear models were conducted to assess direct effects of item-level PBS on alcohol-related consequences and the moderating effects of drinking motives. RESULTS: Two PBS items were associated with fewer alcohol-related consequences at follow-up, and two items were associated with greater alcohol-related consequences at follow-up. Drinking motives differentially moderated associations between item-level PBS and alcohol-related consequences for a proportion in the sample. Enhancement motives moderated the greatest number of associations, followed by coping, conformity, and social motives. Certain PBS (e.g., drink slowly, rather than gulp or chug) were moderated by several drinking motives, whereas other PBS items were not moderated by any motives. CONCLUSION: Consistent with previous research, some item-level PBS were associated longitudinally with increased negative consequences, and some were associated with decreased negative consequences. Drinking motives, particularly enhancement, moderated several item-level PBS and consequence associations, suggesting that reasons for drinking may be important for understanding the associations between PBS strategies and alcohol-related consequences.

Alcohol First, Cannabis Last: Identification of an Especially Risky Use Pattern among Individuals Who Co-Use Alcohol and Cannabis.

Background: Alcohol and cannabis co-use is common and confers increased risk for potential harms, such as negative consequences and substance dependence. The existing evidence suggests that factors such as dose of delta-9-tetrahydrocannabinol (THC) consumed and order of use of each substance (i.e., using alcohol or cannabis first or last when co-using) may impact co-use outcomes. Existing co-use research has focused primarily on college-samples or young adults, and few studies have explored these nuanced relations among community samples. Methods: We examined survey data from 87 community members (mean age 32.9 years, 49.4% female) recruited from legal market cannabis dispensaries. Using a combination of regression techniques (i.e., OLS, negative binomial, censor-inflated) we modeled relations among co-use ordering patterns, THC dose and cannabis outcomes as well as interactions with sex assigned at birth and age. Results: Individuals who endorsed co-use reported significantly higher CUDIT scores than those who had never co-used (p < 0.01). Using alcohol first and cannabis last (a pattern we refer to as "AFCL") was more common among females than males (p < 0.01). In the context of typical substance use weeks, more frequently engaging in the AFCL pattern was associated with significantly higher CUDIT scores (p < 0.001) and negatively predicted positive consequences (p < 0.001). Other patterns predicted higher CUDIT scores during heavy use weeks. Conclusions: Results indicate that co-use ordering patterns are related to substance use outcomes. Further research leveraging within-subjects, longitudinal designs is needed to test causal relations between these variables.

Using Latent Profile Analysis to Examine Cannabis Use Contexts: Associations with Use, Consequences, and Protective Behaviors.

OBJECTIVE: College students represent a large portion of the population, and report high rates of cannabis use and related negative outcomes, including interpersonal problems, risky behaviors, or physical dependency. The contexts in which students use cannabis (e.g., at a party, when feeling down or depressed, after a fight with a loved one) likely affect their risk of experiencing consequences. We aimed to discern profiles of cannabis use contexts and compare profiles on use frequency, consequences, and the use of cannabis protective behavioral strategies (PBS). METHOD: College students were surveyed regarding their cannabis use contexts, frequency, consequences, and PBS use (n = 265; female = 72.8%). We used Latent Profile Analysis to identify patterns of cannabis use contexts and auxiliary testing to compare profiles on use frequency, consequences, and PBS use. RESULTS: Our examination revealed three latent profiles of cannabis use. The Social Use Profile was associated with use in predominantly social/uplifting contexts. The Physical & Emotional Pain Profile was also associated with use in these contexts but was defined by additional use in response to pain. The All Contexts Profile was associated with frequent use in all contexts, including those that were least endorsed by the other profiles. Profiles differed in cannabis use frequency, PBS use, and the number of consequences experienced, such that profiles were more likely to be associated with more frequent cannabis use, higher risk of experiencing use-consequences, and using fewer PBS as the number of use contexts increased across the profiles. CONCLUSIONS: The contexts in which people use cannabis are associated with cannabis risk and protection. Prevention and intervention efforts may benefit from considering contexts of cannabis use.

Results of a randomized controlled trial of the cannabis eCHECKUP TO GO personalized normative feedback intervention on reducing cannabis use, cannabis consequences, and descriptive norms.

BACKGROUND: The prevalence of cannabis use disorder and its negative consequences among young adults has highlighted the need for prevention and early intervention programs. However, low treatment prevalence persists due to factors such as lack of perceived need, concerns about stigma, and limited access to treatment. To address these barriers, web-based cannabis interventions have been developed, but their efficacy remain limited. This study aims to evaluate the cross-site efficacy of the Cannabis eCHECKUP TO GO program, a web-based Personalized Normative Feedback and Protective Behavioral Strategies intervention for reducing cannabis use frequency and consequences in college students with willingness to change. METHODS: Participants were 781 students from three universities (two in Canada, one in the US) who reported using cannabis in the past month and expressed interest in reducing or engaging in safer cannabis use. The study randomly assigned them to either an experimental group that received personalized normative feedback or a control group that received information on healthy stress management. The study collected follow-up data 4 weeks after the initial intervention and measured participants' frequency of cannabis use, number of cannabis consequences, descriptive and injunctive norms at both time points. RESULTS: The results showed no significant reductions in cannabis use or negative consequences of use. However, students who received personalized normative feedback experienced a significant reduction in descriptive norms related to cannabis use, to be more in line with actual use. CONCLUSION: This study suggests that more targeted interventions may be necessary for university students who are already using and seeking help to reduce their use.

Disentangling trait and daily experiences of uncertainty and meaning in life: implications for daily anxiety, negative affect, and somatic symptoms.

BACKGROUND: Although there is growing evidence supporting the association between intolerance of uncertainty (IU) and psychopathology, little is known about the covariation of IU and psychological distress day-to-day. The purpose of this ecological momentary assessment (EMA) study was to examine negative emotional and somatic correlates of trait IU and daily uncertainty, while investigating how a source of stability, meaning in life (MIL), might buffer against deleterious effects of IU and uncertainty. DESIGN AND METHODS: Adult community members (n = 62) from a mid-size town in the Rocky Mountain region completed baseline measures of IU and MIL and ecological momentary assessments (EMA) of meaning, uncertainty, affect, and somatic symptoms over the course of one week. RESULTS: Results indicate individuals high in trait IU experience more uncertainty day-to-day and greater distress when they feel uncertain compared to individuals lower in trait IU; however, MIL plays a stronger protective role for high IU compared to low IU individuals. CONCLUSIONS: These findings support and extend previous research showing IU is associated with psychological distress and that MIL may be a critical resource to cultivate. Interventions promoting meaning day-to-day may reduce the effects of uncertainty on the well-being of those highly intolerant of uncertainty.

Preliminary psychometric properties of an inhibition task in young children with Down syndrome.

Background: Executive function (EF) skills are important treatment targets for people with Down syndrome (DS); however, few EF measures have been evaluated for use with young children in this population. Methods: The present study evaluated preliminary psychometric properties of a measure of the EF component of inhibition. Participants were 73 children with DS between 2.5 and 8.67 years old who completed an adapted ability to delay task using a desirable toy. Results: Across two separate trials, latencies to touch the toys were significantly correlated. Latencies increased overall with chronological and mental age, with caveats for the youngest and oldest participants. Conclusion: Findings suggest that an adapted prohibition task is an appropriate method of measuring inhibition for children with DS between 4 and 7 years old, though many children in this chronological age range are at early stages of acquiring this skill set.

The Epidemic-Pandemic Impacts Inventory (EPII): A multisample study examining pandemic-related experiences and their relation to mental health.

The Epidemic-Pandemic Impacts Inventory (EPII) was developed to assess pandemic-related adverse and positive experiences across several key domains, including work/employment, home life, isolation, and quarantine. Several studies have associated EPII-assessed pandemic-related experiences with a wide range of psychosocial factors, most commonly depressive and anxiety symptoms. The present study investigated the degree to which specific types of COVID-19 pandemic-related experiences may be associated with anxiety and depression risk, capitalizing on two large, independent samples with marked differences in sociodemographic characteristics. The present study utilized two adult samples: participants (N = 635) recruited online over a 4-week period in early 2020 (Sample 1) and participants (N = 908) recruited from the student body of a large Northeastern public university (Sample 2). We employed a cross-validated, least absolute shrinkage and selection operator (LASSO) regression approach, as well as a random forest (RF) machine learning algorithm, to investigate classification accuracy of anxiety/depression risk using the pandemic-related experiences from the EPII. The LASSO approach isolated eight items within each sample. Two items from the work/employment and emotional/physical health domains overlapped across samples. The RF approach identified similar items across samples. Both methods yielded acceptable cross-classification accuracy. Applying two analytic approaches on data from two large, sociodemographically unique samples, we identified a subset of sample-specific and nonspecific pandemic-related experiences from the EPII that are most predictive of concurrent depression/anxiety risk. Findings may help to focus on key experiences during future public health disasters that convey greater risk for depression and anxiety symptoms.

Longitudinal Predictors of Neurodevelopmental Outcomes in Children with Down Syndrome.

This study examined longitudinal predictors of neurodevelopmental outcomes in children with Down syndrome (DS). Participants were assessed at Wave 1 during infancy on measures of looking behavior and caregivers provided infant sensory ratings. At Wave 2, child-age participants completed a developmental assessment and caregivers provided ratings of executive function, ADHD symptoms, and autism symptoms. Longer looking durations and greater sensory dysregulation during infancy were predictive of higher ADHD symptom ratings and other neurodevelopmental outcomes during childhood. The findings suggest that early indicators of neurodevelopmental dysregulation may be detectable during infancy in DS.

Psychometric evaluation of a working memory assessment measure in young children with Down syndrome.

BACKGROUND: Working memory involves the temporary storage and manipulation of information and is frequently an area of challenge for individuals with Down syndrome (DS). Despite the potential benefits of intervention, laboratory assessments of working memory that could capture intervention effects have not undergone rigorous evaluation for use with young children with DS. It is critical to evaluate assessments of working memory in young children with DS to ensure the reliable and accurate measurement of performance. AIM: This study evaluated an adapted laboratory measure of working memory for young children with DS 2-8 years old. METHOD: A self-ordered pointing task, the Garage Game, was administered to 78 children with DS (mean = 5.17 years; SD = 1.49). Adaptations were made to the task to minimize potential DS phenotype-related language and motor confounds. RESULTS: Results indicate that the measure is feasible, scalable, and developmentally sensitive, with minimal floor and practice effects for this population within this chronological and developmental age range. CONCLUSION: These findings demonstrate that the Garage Game is promising for use in studies of early working memory and treatment trials that aim to support the development of this critical dimension of executive functioning for children with DS.

Utility of the Brief Young Adult Alcohol Consequences Questionnaire to Identify College Students At-Risk for Alcohol Related Problems: Relative Operating Characteristics across Seven Countries.

Background: It is important to identify students who would benefit from early interventions to reduce harmful drinking patterns and associated consequences. the Brief Young Adult Alcohol Consequences Questionnaire (B-YAACQ) could be particularly useful as a screening tool in university settings. Objectives. The present study examined the utility of the B-YAACQ to distinguish among students at-risk for problematic alcohol use as measured by the AUDIT. Objectives: The present study examined the utility of the B-YAACQ to distinguish among students at-risk for problematic alcohol use as measured by the AUDIT. Methods: A sample of 6382 students (mean age=20.28, SD=3.75, 72.2% females) from seven countries (i.e., U.S., Canada, South-Africa, Spain, Argentina, Uruguay, England) completed the B-YAACQ, the AUDIT and different measures of alcohol use. Results: ROC analyses suggested that a cutoff score of 5 maximized the YAACQ's discrimination utility to differentiate between students at low versus moderate/high risk in the total sample and across countries (except in Canada, where the cutoff was 4). In addition, a cutoff of 7 differentiated between students at low/moderate versus high risk in the total sample, while cutoffs of 10, 9, 8 and 7 differentiate between students at low/moderate versus high risk in Uruguay, U.S and Spain (10), Argentina (9), England (8), and Canada and South-Africa (7), respectively. Students classified at the three risk levels (i.e., low, moderate and high) differed in age (i.e., a younger age was associated with higher risk) and drinking patters (i.e., higher drinking frequency, quantity, binge drinking and AUDIT and B-YAACQ scores in the higher risk groups). Conclusions: This study suggest that the B-YAACQ is a useful tool to identify college students at-risk for experiencing problematic patterns of alcohol use.

Discrete emotions and global affect: Applying empirically driven approaches to experience sampling data to model state and trait affective structure and affect-alcohol use associations in a heavy drinking young-adult sample.

Affective functioning is central to most contemporary models of alcohol use. However, the affective structure at the within- and between-person levels is rarely investigated nor is the differential predictive value of specific affect dimensions assessed across state and trait formats. We examined a) the structure of state and trait affect using experience sampling methodology (ESM) and b) predictive associations between the empirically derived affect facets and alcohol use. Participants were 92 heavy drinking college students aged 18-25 who completed 8 momentary assessments of their affect and drinking a day for 28-days. We found evidence for a single positive affect factor at both the within- (i.e., state) and between-person (i.e., trait) levels. We found a hierarchical factor structure for negative affect, represented by a general, superordinate dimension as well as facet-level sadness, anxiety, and anger dimensions. Associations between affect and alcohol use differed across trait and state levels and across specific types of negative affect. Lagged state positive affect and sadness as well as trait positive affect and sadness were inversely associated with drinking. Lagged state anxiety and trait general negative affect were positively associated with drinking. Thus, our study demonstrates how associations between drinking and affect can be studied in relation to general (e.g., general negative affect) and more specific aspects of affective experiences (e.g., sadness versus anxiety) concurrently within the same study and across trait and state levels of assessment.

Early Birds and Night Owls: Distinguishing Profiles of Cannabis Use Habits by Use Times with Latent Class Analysis.

Background: Understanding, predicting, and reducing the harms associated with cannabis use is an important field of study. Timing (i.e., hour of day and day of week) of substance use is an established risk factor of severity of dependence. However, there has been little attention paid to morning use of cannabis and its associations with negative consequences. Objectives: The goal of the present study was to examine whether distinct classifications of cannabis use habits exist based on timing, and whether these classifications differ on cannabis use indicators, motives for using cannabis, use of protective behavioral strategies, and cannabis-related negative outcomes. Methods: Latent class analyses were conducted on four independent samples of college student cannabis users (Project MOST 1, N=2,056; Project MOST 2, N=1846; Project PSST, N=1,971; Project CABS, N=1,122). Results: Results determined that a 5-class solution best fit the data within each independent sample consisting of the classes: (1) "Daily-morning use",(2) "Daily-non-morning use", (3) "Weekend-morning use", (4) "Weekend-night use", and (5) "Weekend-evening use." Classes endorsing daily and/or morning use reported greater use, negative consequences and motives, while those endorsing weekend and/or non-morning use reported the most adaptive outcomes (i.e., reduced frequency/quantity of use, fewer consequences experienced, and fewer cannabis use disorder symptoms endorsed). Conclusions: Recreational daily use as well as morning use may be associated with greater negative consequences, and there is evidence that most college students who use cannabis do avoid these types of use. The results of the present study offer evidence that timing of cannabis use may be a pertinent factor in determining harms associated with use.

Intersecting sex and American Indian identity moderates school and individual correlates of binge drinking among reservation-area adolescents.

Reservation-area American Indian (AI) youth demonstrate higher rates of binge drinking (BD) than their non-AI peers. However, individual and school-level differences in BD disparities between reservation-area AI/non-AI female and male adolescents remain unexamined. This study applies an Intersectional framework to examine risk and protective factors of BD among reservation-area youth at the intersection of their sex and AI identities. A nationally representative sample of adolescents (N = 14,769; Mage = 14.6, 49% female; 61% AI) attending 103 reservation-serving schools completed a survey between 2015 and 2019. Multilevel modeling was used to examine differences in risk and protective factors of BD between AI and non-AI male and female adolescents. Our findings indicate that the effects of student and school-level risk and protective factors on adolescents' BD are driven primarily by sex within AI and non-AI groups. Implications for future confirmatory research and tailoring school-based prevention programs are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Latent profiles of cannabis use, protective behavioral strategies, and health beliefs in college students.

College student cannabis use is prevalent and heterogeneous, with some students experiencing cannabis-related problems. Cannabis protective behavioral strategies (PBS) are cognitive-behavioral strategies associated with reduced cannabis use and problems. There is a need for theory-informed and person-centered research to better understand cannabis PBS. The current study applied the health belief model (HBM) and latent profile analysis to discern patterns of cannabis use, PBS, and health beliefs among college students. Students (n = 164; Mage = 18.8; 53% female) who endorsed past-month cannabis use completed an online survey between September and November 2017. The 3-profile model best fit the data. Profile 1 (24.3%) represents the "infrequent use/high protection" profile characterized by using cannabis about 1-9 times, high PBS use, high perceived threat and benefits, and moderate perceived barriers. Profile 2 (38.1%) represents the "occasional use/moderate protection" profile characterized by using cannabis about 20-59 times, moderate PBS use, moderate perceived threat and benefits, and low perceived barriers. Profile 3 (37.6%) represents the "frequent use/low protection" profile characterized by using cannabis about 80 or more times, low PBS use, low perceived threat and benefits, and high perceived barriers. Profiles did not differ by age, ethnicity/race, sex, or college year, though varied significantly by age at first cannabis use, cannabis availability, cannabis problems, use frequency, and use context. Results provide preliminary support for distinct patterns of cannabis use, PBS, and health beliefs that align with the HBM. Results highlight the importance of considering how students perceive cannabis PBS and problems and how those beliefs may influence their PBS and cannabis use.

A Comparison of COVID-19 Outcomes Between Reservation-Area American Indian and U.S. National Students.

Introduction: This study presents data from 2 population-based surveys of youth (reservation-area American Indian adolescents and U.S. adolescents) on self, family, and friend morbidity and changes in substance use and negative impacts during COVID-19. Methods: Data were obtained in spring 2021 from surveys of American Indian students living on or near reservations (8th grade, n=398; 10th grade, n=367; 12th grade, n=290) and national students from Monitoring the Future (8th grade, n=11,446; 10th grade, n=11,792; 12th grade, n=9,022). The main outcomes were COVID-19 testing, perceived morbidity/mortality, substance-use changes, and emotional changes during COVID-19. Results: The American Indian sample had a greater proportion of testing (e.g., American Indian 8th grade: 58.1% [95% CI=48.6, 68.8]; Monitoring the Future 8th grade: 43.6% [95% CI=39.8, 47.5]) and friend/family hospitalization (e.g., American Indian 8th grade: 36.2% [95% CI=26.2, 47.5]; Monitoring the Future 8th grade: 11.9% [95% CI=10.6, 13.3]). Across grades, greater proportions of the national sample reported increased anxiety, anger, boredom, loneliness, depression, worry, and trouble concentrating, whereas greater proportions of reservation-area American Indians reported decreased anxiety, loneliness, and depression. Conclusions: Findings indicate that reservation-area American Indian youth experienced unique health consequences 1 year into the COVID-19 pandemic compared with national students, illustrating the need for American Indian-specific COVID-19 public health monitoring and response.

Expectancies that Predict Cannabis Initiation in Response to Legalization.

Background: Recent and prospective changes to nonmedical/recreational cannabis laws in the United States and abroad raise questions about how legalization may influence cannabis use behaviors. Objectives: In the current study, we examined links between legalization, context-specific likelihood of using cannabis, and cannabis expectancies using cross-sectional survey data from 121 college students who had never used or were abstaining from cannabis in a U.S. state where laws prohibit nonmedical cannabis. Results: We found that across scenarios, 61% of students reported they would be more likely to use cannabis if it were legal. Social/sexual facilitation expectancies predicted a higher likelihood of using cannabis after legalization in a social context. Relaxation/tension reduction expectancies predicted a higher likelihood of using in an anxiety relief context. Perceptual/cognitive enhancement expectancies predicted a higher likelihood of using in a pain relief context. Cognitive/behavioral impairment expectancies predicted a lower likelihood of using in social, pain relief, relaxation, and concert contexts. Global negative effects expectancies predicted a lower likelihood of using in relaxation and concert contexts. Conclusions: Our findings suggest that among college students who do not use cannabis, expectancies are linked to cannabis use likelihood in certain contexts if cannabis were legal. This work highlights cannabis expectancies and contexts as possible targets for evidence-based public health education and clinical prevention initiatives related to the potential increase in cannabis use associated with cannabis policy implementation. College students may benefit from initiatives that address cannabis expectancies and enhance harm reduction skills to help them effectively navigate contexts in which cannabis is available to them.
