Alcohol use from adolescence through early adulthood: an assessment of measurement invariance by age and gender

Changes in alcohol consumption among Belgian adults participating in the internet-based one-month-abstinence campaign 'Tournée Minérale'

BACKGROUND AND OBJECTIVE

Temporary abstinence campaigns (TAC) are a promising approach to reduce alcohol consumption. This study examined changes in (at-risk) alcohol consumption and determinants of alcohol consumption among Belgian adults participating in the Tournée Minérale Campaign (TMC, Belgian TAC). In addition, moderating effects of age, sex, education level, successfully refraining from alcohol during TMC, risk drinking, drinking levels and binge drinking were investigated.

METHODS

TMC is a fully automated mass media prevention campaign challenging Belgian adults to refrain from alcohol during the month February. This study includes a baseline, post- (four weeks after TMC) and follow-up (six months after TMC) test using online recruitment and an online questionnaire. Participants were self-selected by signing up on the TMC website. Repeated measures ANCOVAs were used to examine changes over time in alcohol consumption (log transformed due to skewness) and determinants among TMC participants (n = 8,730, 48.4 ± 12.9 years old, 37.4% males) who filled in all three measurements. Moderation effects were assessed for age, sex, education level, successfully refraining from alcohol during TMC, risk drinking, drinking levels and binge drinking at baseline. McNemar tests were used to examine the change in prevalence of risk drinking and binge drinking.

RESULTS

TMC participants showed a significant decrease in weekly alcohol consumption (mean exp(x)-1) and CI) from baseline (6.2 [6.4,6.7]) to post (4.2 [4.1,4.3], F = 22.0, p < .001 d = -2.4 [-2.4,-2.3]) and from baseline to follow-up (5.1 [4.9,5.2], F = 24.2, p < .001, d = -1.5 [-1.5,-1.4]), and an increase from post to follow-up (F = 21.1, p < .001). In the short term (from baseline to post), the decreases were stronger among older, male and lower educated TMC participants, those successfully refraining during TMC, higher risk drinkers and binge drinkers. In the medium term (from baseline to follow-up), changes in alcohol consumption were moderated by education (stronger among lower educated) and risk drinking (increase in lower risk drinkers and decrease in higher risk drinkers). Participants' baseline drinking level moderated changes in alcohol consumption. Both short and medium term increases in alcohol consumption were observed among those with a low drinking level (those who drank 0 to < 4 glasses at baseline), while short and medium term decreases were observed among those with higher drinking levels, i.e. those with moderate (≥ 4 to ≤ 10 glasses), high (> 10 to ≤ 17 glasses) and highest (> 17 glasses) drinking level at baseline. A reduction in the proportion of risk drinkers and binge drinkers and changes in determinants of alcohol consumption (e.g. attitudes towards drinking less alcohol and habit of drinking alcohol) were observed among TMC participants.

CONCLUSIONS

TMC participants reported favourable changes in (the underlying determinants of) alcohol consumption in the short and medium term. Higher level drinkers appear to be especially attracted to participate in TMC and to experience the strongest decreases in alcohol consumption. However, without comparison with a control group of non-participants or comparison points, we cannot simply attribute the changes over time to participation in TMC. Future research with a stronger study design is needed to rule out possible bias (e.g., selection bias, seasonal effects or regression to the mean) and to examine mechanisms and longer term effects of TACs.

Influencer Drinking Norms: Cross-Sectional Mediators of Alcohol-Related Social Media and College Drinking

Background: Social influences from peers, such as the perceptions of how much one's peers drink (i.e., descriptive drinking norms) are robust predictors of college drinking. In the digital age, these influences can happen on social media through viewing posts shared by peers depicting drinking (alcohol-related content). Social media influencers also post alcohol-related content and are popular among students. However, less is known about whether influencer drinking norms potentially mediate the association between viewing influencer alcohol-related content and drinking. Methods: College students who drink alcohol (N = 528) completed an online survey which assessed if they followed influencers who posted alcohol-related content, how often they perceived the influencer shared the content, influencer norms, and personal alcohol consumption and consequences. Results: Findings from two cross-sectional mediation models revealed that influencer norms mediated associations between following more influencers who shared alcohol-related content or frequency of influencer content and participant drinking. Conclusions: These findings suggest that influencer norms are uniquely linked to students' drinking habits. Further, it extends prior research in the influencer domain by examining how perceptions of how much influencers drink (i.e., descriptive norms) may impact college drinking.

Experiences of Discrimination and Alcohol Involvement Among Young Adults at the Intersection of Race/Ethnicity and Gender

Although discrimination is an important social determinant of alcohol involvement, there is a dearth of research testing these associations across race/ethnicity and gender. This is an important research gap given that experiences of discrimination and therefore links with alcohol involvement may vary as a function race/ethnicity and gender intersectional identities. We tested for measurement invariance in discrimination and alcohol involvement and examined group differences in means and covariances. The sample consisted of n = 1187 young adults (ages 18-26; n = 193 Black women, n = 209 Latina women, n = 186 White women, n = 198 Black men, n = 203 Latino men, and n = 198 White men). We found evidence for differential item functioning for discrimination and alcohol involvement that violated assumptions needed to make manifest between-group comparisons. To model the source and degree of differential item functioning, we used partial measurement invariance and dropped a discrimination item that did not reliably overlap with the latent factor for White women. After accounting for differential item functioning, Black women and men reported the highest discrimination, followed by Latinx women and men, and then White women and men. White women reported the most alcohol involvement, followed by White men, Latina women, Latino men, Black men, and Black women. Discrimination and alcohol involvement were positively associated for all groups except White women, though effect sizes varied with Black men exhibiting the largest effect. An intersectionally valid understanding of discrimination and alcohol involvement may necessitate statistical approaches that can test for (and model) differential item functioning prior to making between-group quantitative comparisons.

The impact of the COVID-19 pandemic experiences on college drinking via mental distress: Cross-sectional mediation moderated by race

BACKGROUND

The COVID-19 pandemic has been linked to stress, anxiety, and depression among college students, with heightened distress tied to greater drinking for some individuals. Emerging research suggests that these associations may differ across race, but few studies use adequate samples to examine this, particularly among college students, an at-risk population for both heavy drinking and mental distress. Specifically, pandemic-related stressors and mental distress may be higher among Black students than White students. The current study examined: (1) whether mental distress cross-sectionally mediates the association between pandemic-specific stressors and drinking and (2) whether race (Black or White) moderates these associations.

METHODS

A cross-sectional online survey of 400 college drinkers (43% White, 28% Black) in fall 2020 assessed pandemic-related stressors (e.g., losing a job, contracting COVID-19, changed living situation), mental distress (stress, anxiety, depression), and drinking (past-month drinking, perceived changes since the start of the pandemic).

RESULTS

Cross-sectional mediation models indicated that financial stressors and social distancing were linked to greater quantity and frequency of past-month drinking through greater mental distress. For perceived changes in drinking, only financial stressors were linked to drinking greater quantities and drinking more often (compared to pre-pandemic levels) via mental distress. Moderated mediation models among students identifying as White or Black revealed that changed living situation was a robust stressor across race. Financial stressors and social distancing were linked with greater distress only among White students, whereas essential worker status was a protective factor against distress only among Black students.

CONCLUSIONS

Select stressors were linked to increased drinking through greater mental distress, with differential risks across Black versus White students. Findings suggest campus administrators should focus on connecting students with resources (e.g., counseling centers and health promotion offices) during times of distress.

Educational level and alcohol use in adolescence and early adulthood-The role of social causation and health-related selection-The TRAILS Study

Both social causation and health-related selection may influence educational gradients in alcohol use in adolescence and young adulthood. The social causation theory implies that the social environment (e.g. at school) influences adolescents' drinking behaviour. Conversely, the health-related selection hypothesis posits that alcohol use (along other health-related characteristics) predicts lower educational attainment. From past studies it is unclear which of these mechanisms predominates, as drinking may be both a cause and consequence of low educational attainment. Furthermore, educational gradients in alcohol use may reflect the impact of 'third variables' already present in childhood, such as parental socioeconomic status (SES), effortful control, and IQ. We investigated social causation and health-related selection in the development of educational gradients in alcohol use from adolescence to young adulthood in a selective educational system. We used data from a Dutch population-based cohort (TRAILS Study; n = 2,229), including measurements of educational level and drinking at ages around 14, 16, 19, 22, and 26 years (waves 2 to 6). First, we evaluated the directionality in longitudinal associations between education and drinking with cross-lagged panel models, with and without adjusting for pre-existing individual differences using fixed effects. Second, we assessed the role of childhood characteristics around age 11 (wave 1), i.e. IQ, effortful control, and parental SES, both as confounders in these associations, and as predictors of educational level and drinking around age 14 (wave 2). In fixed effects models, lower education around age 14 predicted increases in drinking around 16. From age 19 onward, we found a tendency towards opposite associations, with higher education predicting increases in alcohol use. Alcohol use was not associated with subsequent changes in education. Childhood characteristics strongly predicted education around age 14 and, to a lesser extent, early drinking. We mainly found evidence for the social causation theory in early adolescence, when lower education predicted increases in subsequent alcohol use. We found no evidence in support of the health-related selection hypothesis with respect to alcohol use. By determining initial educational level, childhood characteristics also predict subsequent trajectories in alcohol use.

Parent-child Relationships and Sexual Minority Youth: Implications for Adult Alcohol Abuse

Sexual minority (lesbian, gay, bisexual, and same-sex attracted) youth and adults report elevated rates of alcohol use and abuse relative to their heterosexual peers; these differences are strongest for sexual minority girls and women. Although preliminary evidence suggests that unsupportive parenting and maladaptive parent-child relationship qualities are associated with concurrent substance use among sexual minority youth, questions remain about the long-term implications of these early familial experiences on drinking behaviors among sexual minority youth and adults. Nationally-representative prospective data (n = 14,800; 53.1% female; Wave 1 Mean age = 15.61; Wave 4 Mean age = 28.51) were used to test the longitudinal association between parent-child relationships and parental autonomy granting between the ages of 13-18, and sexual-orientation-related disparities in alcohol abuse during adulthood. The findings showed that adolescent same-sex attraction was associated with alcohol abuse during adulthood for sexual minority women and that deficits in parent-child relationship quality statistically mediated this association. No sexual orientation differences in alcohol abuse were found among men. The findings suggest that the quality of relationships with parents in early adolescence has long-lasting impact on sexual minority women's vulnerability for alcohol abuse. Early interventions that bolster supportive parent-child relationship qualities may have enduring consequences for sexual minority women's alcohol use across the life course.

Aggressive-Depressive Trajectories in Childhood and Their Associations with Drinking Behaviors and Problems in Adolescence and Emerging Adulthood

Research indicates that externalizing and internalizing pathways emanated in childhood are connected to later drinking behaviors; however, no study has investigated the contemporaneous effects of the two pathways using a person-centered approach that categorizes individuals based on their various developmental patterns. This study examined the distinct patterns of concurrent development of aggression and depressive symptoms in childhood and their associations with later drinking behaviors using data from a 15-year Taiwanese cohort since age 8 (N = 2854, 49% females). Group-based multi-trajectory modeling identified four aggressive-depressive trajectory groups: Moderate, Aggressive, Depressive, and Comorbid, which manifested a sequential risk gradient in alcohol use. Comorbid group, characterized by persistently high levels of aggression and depressive symptoms, has the highest levels of alcohol use and drinking problems and the earliest onset of drinking. Aggressive and Depressive groups have higher levels of alcohol use and earlier onset of drinking than Moderate group. These findings imply the importance of monitoring aggression and depressive symptoms simultaneously and continually in childhood to prevent later drinking.

Sexual Orientation-Related Disparities in High-Intensity Binge Drinking: Findings from a Nationally Representative Sample

Purpose: The purpose of this study was to assess sexual orientation differences in high-intensity binge drinking using nationally representative data. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions III (N = 36,309), a nationally representative sample of U.S. adults collected in 2012-2013. Sex-stratified adjusted logistic regression models were used to test sexual orientation differences in the prevalence of standard (4+ for women and 5+ for men) and high-intensity binge drinking (8+ and 12+ for women; 10+ and 15+ for men) across three dimensions of sexual orientation: sexual attraction, sexual behavior, and sexual identity. Results: Sexual minority women, whether defined on the basis of sexual attraction, behavior, or identity, were more likely than sexual majority women to engage in high-intensity binge drinking at two (adjusted odds ratios [aORs] ranging from 1.52 to 2.90) and three (aORs ranging from 1.61 to 3.27) times the standard cutoff for women (4+). Sexual minority men, depending on sexual orientation dimension, were equally or less likely than sexual majority men to engage in high-intensity binge drinking. Conclusion: This study is the first to document sexual orientation-related disparities in high-intensity binge drinking among adults in the United States using nationally representative data. The results suggest that differences in alcohol-related risk among sexual minority individuals vary depending on sex and sexual orientation dimension.

Financial Stress and Drinking During the Transition to Adulthood: The Role of Parental Financial Support

We investigated the concurrent and prospective associations between financial stress and drinking during the transition to adulthood in the United States, drawing from two distinct stress and coping perspectives as competing explanations for the direction of associations: the Transaction Model of Stress (TMS) and the Conservation of Resources (CoR) model. Because many emerging adults rely on continuing financial support from parents, we examined the role of parental support on these associations. We tested these associations using longitudinal structural equation modeling (SEM) with data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) (N=9,026) collected at two timepoints: early emerging adulthood (ages 18-26) and five years later. Consistent with CoR, financial stress reduced concurrent drinking. Furthermore, parental financial support reduced adult children's financial stress but increased drinking in early emerging adulthood. We discuss the findings in regards to facilitating the transition to adulthood.

Measuring alcohol use across the transition to adulthood: Racial/ethnic, sexual identity, and educational differences

BACKGROUND

Patterns of alcohol use change from adolescence to adulthood and may differ based on race/ethnicity, sexual identity, and education. If alcohol use measures do not operate consistently across groups and developmental periods, parameter estimates and conclusions may be biased.

OBJECTIVES

To test the measurement invariance of a multi-item alcohol use measure across groups defined by race/ethnicity, sexual identity, and college education during the transition to adulthood.

METHODS

Using three waves from the National Longitudinal Study of Adolescent to Adult Health, we tested configural, metric, and scalar invariance of a 3-item alcohol use measure for groups defined by race/ethnicity, sexual identity, and college education at three points during the transition to adulthood. We then assessed longitudinal measurement invariance to test the feasibility of modeling developmental changes in alcohol use within groups defined by these characteristics.

RESULTS

Overall, findings confirm notable variability in the construct reliability of a multi-item alcohol use measure during the transition to adulthood. The alcohol use measure failed tests of metric and scalar invariance, increasingly across ages, both between- and within-groups defined by race/ethnicity, sexual identity, and college education, particularly among females.

CONCLUSIONS

Measurement testing is a critical step when utilizing multi-item measures of alcohol use. Studies that do not account for the effects of group or longitudinal measurement non-invariance may be statistically biased, such that recommendations for risk and prevention efforts could be misguided.
