Codevelopment Between Key Personality Traits and Alcohol Use Disorder From Adolescence Through Young Adulthood

Personality changes related to presence and treatment of substance use (disorders): a systematic review

Heavy substance use (SU) and substance use disorders (SUD) have complex etiologies and often severe consequences. Certain personality traits have been associated with an increased risk for SU(D), but far less is known about personality changes related to SU(D). This review aims to synthesize the existing literature on this research question. A systematic literature search was conducted from November 2022 to February 2023 in PubMed, EbscoHost, and Web of Science. Peer-reviewed original papers on SU(D)-related personality changes were included. Of 55 included studies, 38 were observational population-based studies and 17 were intervention studies. Overall, personality and SU measures, samples, study designs, and statistical approaches were highly heterogenous. In observational studies, higher SU was most consistently related to increases in impulsivity-related traits and (less so) neuroticism, while interventions in the context of SU(D) were mostly associated with increases in conscientiousness and self-efficacy and lasting decreases in neuroticism. Findings for traits related to extraversion, openness, conscientiousness, and agreeableness were mixed and depended on SU measure and age. Studies on bidirectional associations suggest that personality and SU(D) both influence each other over time. Due to their strong association with SU(D), impulsivity-related traits may be important target points for interventions. Future work may investigate the mechanisms underlying personality changes related to SU(D), distinguishing substance-specific effects from general SU(D)-related processes like withdrawal, craving, and loss of control. Furthermore, more research is needed to examine whether SU(D)-related personality changes vary by developmental stage and clinical features (e.g. initial use, onset, remission, and relapse).

Predictors of persistent alcohol use disorder and co-occurring depressive symptoms: Insights from the longitudinal college experiences study

INTRODUCTION

Problematic alcohol use and depression are prevalent in the college student population. The purpose of this study was to identify how personality and social-contextual factors in the first year of college work together to predict stable and potentially co-occurring alcohol use disorder (AUD) and depressive symptoms over a period of approximately 4 years.

METHODS

Participants were first-year college students from the Southeastern United States (N = 209, 90% white, 62% female). Baseline data were collected in the first year of college and follow-up assessments were completed ~1 and ~4 years later (retention rates: 80%+, average ages ~19, 20, and 23 years, respectively). At each assessment, participants completed a comprehensive online survey assessing mental health and substance use, as well as personality, social support, stress, sleep, and other features of peer and romantic partner affiliations.

RESULTS

Results from our random-intercept cross-lagged panel model indicated AUD and depressive symptoms were more likely to co-occur in the transition out of rather than into college. Significant predictors of stable AUD symptoms across the ~4-year period included greater alcohol quantity, marijuana frequency, affiliation with antisocial/substance-using peers, and frequency of drinking with romantic partner in the first year of college. Significant predictors of stable depressive symptoms included greater constraint, greater negative emotionality, lower positive emotionality, greater stress, and less weekday sleep.

CONCLUSIONS

Findings suggest that personality factors, stress, and sleep in the first year of college may be useful targets to screen for in efforts to reduce long-term depressive symptoms in the college context. Disrupting affiliation with antisocial/substance-using peers and romantic partners and reducing the high quantity of alcohol and frequency of marijuana may be more relevant to reducing long-term problematic alcohol use. Implications for incorporating individually-tailored approaches to prevention/intervention are addressed.

Role of pregaming motives in accounting for links between maladaptive personality traits and drinking consequences

College students are at heightened risk of engaging in unhealthy alcohol use that leads to negative consequences (e.g., motor vehicle accidents, poor academic performance). Understanding how individual differences, such as maladaptive personality traits, contribute to that risk could improve intervention efforts. A potential pathway through which personality confers risk for consequences is by influencing students' motivation to drink. In this study of 441 college students, we investigated whether different motivations to pregame, a particularly risky and common drinking practice on college campuses, accounts for links between maladaptive traits and alcohol-related consequences. Results of bivariate analyses showed that all pregaming motives and maladaptive traits (except detachment) were strongly correlated with negative consequences. In path analytic models that adjusted for shared variance between pregaming motives and between maladaptive traits, results showed that traits had indirect effects on total drinking consequences via individual differences in pregaming motives as well as direct effects that were independent of motives. Specifically, antagonism, disinhibition, and negative affectivity predicted more drinking consequences via stronger motives to pregame for instrumental reasons over and above the general motivation to pregame, whereas detachment predicted fewer consequences via weaker instrumental pregaming motives. Antagonism and disinhibition were also associated with more drinking consequences, and detachment with fewer consequences, over and above pregaming motives and general personality problems. Our study indicates that one way maladaptive personality traits may shape alcohol-related consequences in college students is by associations with their motivations to pregame.

The reciprocal relationships between social media self-control failure, mindfulness and wellbeing: A longitudinal study

This paper aims to shed light on the question whether, and how, social media self-control failure is related to mindfulness and wellbeing. Using a 3-wave longitudinal design, the present study among 594 daily social media users examined the reciprocal relationships between social media self-control failure and mindfulness, and between social media self-control failure and wellbeing (as assessed by subjective vitality and life satisfaction). Results of the random-intercept cross-lagged panel model showed that social media self-control failure has a time-invariant negative association with mindfulness and subjective vitality. No full reciprocal influence was found between social media self-control failure and mindfulness, yet part of this trajectory was observed, suggesting that social media self-control failure could impair mindfulness, which, in turn, might increase future social media self-control failure. For wellbeing, life satisfaction was found to predict subsequent drops in social media self-control failure.

Interplay between personality and antisocial peer affiliation as prospective predictors of marijuana use and academic achievement in the transition into and out of college

Marijuana use has increased in recent cohorts and is associated with several negative outcomes, including poorer academic achievement. Less is known about how personality and peer factors in the first two years of college work together to predict problematic marijuana use and potentially co-occurring academic problems three years later. The longitudinal College Experiences Study (N = 209) was used to address this (N = 209, ~90% white, ~40% male); this study collected data from students in their first year of college, as well as ~1 year later (retention = 85%), and again ~4 years after the initial data collection (retention = 80%). Longitudinal data were analyzed via the traditional cross-lagged panel (CLPM) and the random-intercept CLPM approach. Results were consistent in that there was strong stability in problematic marijuana use, constraint, and antisocial peer affiliation across time, which were predominately influenced by stable, trait-like influences. These factors were also highly correlated but there was less evidence that one predicted the other over time. Nonetheless, greater constraint at Wave 1 was associated with significantly greater cumulative GPA in the transition out of college (βs = 0.43-0.44). Results support the importance of early prevention and intervention of problematic marijuana use, as well as the possibility of using personality-targeted approaches in the first year of college to promote growth in behaviors related to constraint (e.g., staying organized, risk avoidant) in an effort to improve academic success and correlated substance use outcomes by the transition out of college.

Punch-Drunk or Drunken Boxing? The Etiology of Alcohol-Related Physical Violence through Adolescence and Young Adulthood

BACKGROUND

Alcohol-related physical violence (ARPV) can be a causal consequence of alcohol consumption, but only for specific individuals (e.g., those predisposed to violence). Studies have not accounted for the shared etiology explaining comorbidity between alcohol use and violent behavior as a potential third-variable explanation of ARPV. The current study examined genetically-informed associations between ARPV, heavy alcohol use (HAU) and overall physical violence (OPV) in adolescence and young adulthood, by testing two proposed theories of ARPV processes (HAU causes ARPV, causal relationships depend upon OPV) and how overarching shared covariance may account for these associations.

METHODS

Using the twin and sibling subsample from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a series of biometric models tested hypotheses individually in adolescence and young adulthood. This included estimating bivariate Cholesky and direction-of-causality models, and trivariate Cholesky, independent pathway, and common pathway models.

RESULTS

HAU had a causal effect on ARPV in adolescence and young adulthood. This effect was not moderated by OPV at either developmental stage. A shared etiology or common latent factor did not explain associations between ARPV, OPV, and HAU, even though ARPV strongly covaried independently with HAU and with OPV. Finally, OPV also had a causal effect on ARPV in adolescence, and in young adulthood for adolescent-onset drinkers.

CONCLUSIONS

Causal theories of ARPV still hold when accounting for shared genetic and environmental variance. Further research on the exact role of violence (predispositions, environmental contexts) is required, as both phenotypes substantially (and separately) explain influences driving ARPV.

Personality, romantic relationships, and alcohol use disorder symptoms in adolescence and young adulthood: An evaluation of personality × social context interplay

Prior research has shown that person-level characteristics (e.g., temperament, personality) correlate and interact with social-contextual factors (e.g., parent-child relationship quality, antisocial peer affiliation) to predict adolescent substance use, but less research has examined similar processes for adult substance use problems. We addressed this gap by testing for personality × romantic partner context interplay in relation to symptoms of alcohol use disorder (AUD) at ages 24 and 29. Participants were twins in the longitudinal Minnesota Twin Family Study (N = 2,769; 52% female). Results support the corresponsive principle of personality in that we found that key personality traits in late adolescence (low constraint, negative emotionality) predicted subsequent "selection" into key social contexts in early adulthood (poorer quality romantic relationships and greater romantic partner alcohol use), which subsequently reinforced those traits and associated outcomes (including correlated AUD symptoms) through late young adulthood. There were few meaningful gender differences in these associations. There was also no support for the personality × romantic partner context interaction as a significant predictor of AUD symptoms at ages 24 or 29. Taken together with prior studies, these results suggest that such interactions may be less relevant to the development of young adult AUD compared to adolescent substance use problems.

Explaining trajectories of adolescent drunkenness, drug use, and criminality: A latent transition analysis with socio-ecological covariates

BACKGROUND

Although there are diverse trajectories in adolescent substance use and criminality, it is less clear why some adolescents follow one pathway and not another. In this study, we examine how different domains in a young person's life, such as temperament, peer, and family factors, are linked to different trajectories and whether some domains are more strongly associated with specific patterns of these behaviours.

METHODS

Data comes from the Longitudinal Research on Development in Adolescence (LoRDIA) study in Sweden. Adolescents were surveyed at baseline (n = 755, age 13, grade 7) and followed up at grades 8 and 9. Latent transition analysis and multinomial logistic regression were conducted.

RESULTS

Four distinct statuses were found, showing heterogeneity in adolescent substance use and criminal behaviours. These statuses were however highly stable. Individual, peer and family domains were all relevant in distinguishing between the statuses. A key finding is that the relative importance of these domains differed between statuses, suggesting differential effects of the domains on the different trajectories. The pre-teen family environment, as well as criminal peers, was most strongly associated with a more entrenched group. This was not the case for a 'Dabblers' group, where novelty-seeking was weakly linked. For the 'Occasional Law Breakers', criminal peers was more strongly associated.

CONCLUSIONS

Our results suggest that substance use and criminality in early to mid-adolescence is more diverse than current theories allow. Moreover, the different trajectories in these behaviours are likely to have different causal mechanisms, which has important implications for theory, policy and practice.

Alcohol use and personality change in middle and older adulthood: Findings from the Health and Retirement Study

OBJECTIVE

Personality is known to predict alcohol consumption, but how alcohol use is related to personality change is less clear, especially at older ages. The present study examined the effects of level of alcohol consumption and history of dependence on change in the Five-Factor Model personality traits in a national cohort of Americans aged over 50.

METHOD

Over 10,000 adults who participated in 2006-2008 waves of the Health and Retirement Study reported on personality and alcohol use and were followed over 4 years.

RESULTS

Latent difference score models indicated decreases in Extraversion to be attenuated for individuals categorized as light-to-moderate drinkers at baseline, whereas decreases in Conscientiousness were accentuated by having experienced alcohol dependence symptoms. Moreover, personality difference scores correlated with changes in the amount of alcohol consumed at follow-up.

CONCLUSIONS

The findings suggest that patterns of alcohol consumption are associated with changes in personality across the second half of the life span.
