Daily sensation-seeking and urgency in young adults: Examining associations with alcohol use and self-defined risky behaviors

Prospective associations between sleep, sensation-seeking, and mature screen usage in early adolescents: findings from the Adolescent Brain Cognitive Development study

STUDY OBJECTIVES

Early exposure to mature content is linked to high-risk behaviors. This study aims to prospectively investigate how sleep and sensation-seeking behaviors influence the consumption of mature video games and R-rated movies in early adolescents. A secondary analysis examines the bidirectional relationships between sleep patterns and mature screen usage.

METHODS

Data were obtained from a subsample of 3687 early adolescents (49.2% female; mean age: 11.96 years) participating in the Adolescent Brain and Cognitive Development study. At year 2 follow-up, participants wore Fitbit wearables for up to 21 nights to assess objective sleep measures and completed a scale about sensation-seeking traits. At year 3 follow-up, they answered questions about mature screen usage.

RESULTS

Of the sample, 41.8% of the sample reported playing mature-rated video games and 49% reported watching R-rated movies. Sensation-seeking traits were associated with R-rated movie watching 1 year later. Shorter sleep duration, later bedtime, more bedtime variability, and more social jetlag (discrepancy between the mid-sleep on weekdays and weekends) were associated with mature-rated video gaming and R-rated movie watching 1 year later. Sleep duration variability was associated with mature-rated video gaming. There was also an interaction effect: those with higher sensation-seeking scores and shorter sleep duration reported more frequent R-rated movie usage than those with longer sleep duration. Secondary analyses showed bidirectional associations between later bedtimes, more variability in bedtimes, and more social jetlag with mature screen usage.

CONCLUSIONS

Early adolescents with sensation-seeking traits and poorer sleep health were more likely to engage in mature screen usage.

A socioemotional network perspective on momentary experiences of family conflict in young adults

Family conflict is an established predictor of psychopathology in youth. Traditional approaches focus on between-family differences in conflict. Daily fluctuations in conflict within families might also impact psychopathology, but more research is needed to understand how and why. Using 21 days of daily diary data and 6-times a day experience-sampling data (N = 77 participants; mean age = 21.18, SD = 1.75; 63 women, 14 men), we captured day-to-day and within-day fluctuations in family conflict, anger, anxiety, and sadness. Using multilevel models, we find that days of higher-than-usual anger are also days of higher-than-usual family conflict. Examining associations between family conflict and emotions within days, we find that moments of higher-than-usual anger predict higher-than-usual family conflict later in the day. We observe substantial between-family differences in these patterns with implications for psychopathology; youth showing the substantial interplay between family conflict and emotions across time had a more perseverative family conflict and greater trait anxiety. Overall, findings indicate the importance of increases in youth anger for experiences of family conflict during young adulthood and demonstrate how intensive repeated measures coupled with network analytic approaches can capture long-theorized notions of reciprocal processes in daily family life.

Changes in Restless Sleep, Self-Control, and Alcohol-Related Problems with Police from Late Adolescence to Adulthood

Sleep quality is crucial for healthy adolescent brain development, which has downstream effects on self-control and involvement in risky behaviors, such as alcohol use. While previous studies have found that sleep and facets of self-control are associated with patterns of alcohol use, few have assessed whether these constructs are tied to alcohol-related problems with law enforcement during the transitional period from adolescence to adulthood. The current study uses self-report panel data from ages 16 to 27 from a population-based sample of U.S. youth (N = 956; 36.86% female). The goal of the current study is to assess the association between changes in restless sleep, impulsivity, sensation seeking, and problems with police during or shortly after consuming alcohol from adolescence to adulthood to begin to address this gap in the existing literature. Results from a multivariate latent growth curve model reveal that faster increases in restless sleep and slower declines in impulsivity are associated with slower declines in police contact. Correlated changes between restless sleep, impulsivity, and police contact are slightly greater from ages 16-21 than for ages 22-27, with males showing stronger associations. The reported results suggest that identifying developmental mechanisms between changes in poor sleep, impulsivity, and alcohol use behaviors during this life-course phase will be crucial moving forward to help divert youth away from alcohol-related contact with the police.

A comparative analysis of distracted driving behavior among drivers of different income levels: A case study in huainan, China

This research aims to investigate the differences and causes behind distracted driving behavior among drivers with varying income levels. A comparative survey of 1121 drivers in Huainan City, China, was conducted, including 562 drivers from high-end communities representing the high-income group, and 559 drivers from general communities representing the low-income group. Employing social norms, risk perception, and experience as independent variables, the study further examines the role of in-group bias as a mediating variable, with distracted driving behavior serving as the dependent variable, through the construction of two structural equation models for analysis. The study found that among the high-income driver group, in-group bias significantly mediates the impact of social norms, risk perception, and experience on distracted driving behavior; however, this mediating effect is less pronounced in the low-income driver group. This finding is crucial for understanding the potential distracted driving behaviors induced by in-group bias within the high-income driver group and for effectively promoting driving safety. In summary, this research provides new insights into reducing distracted driving behavior among the high-income driver group, thereby enhancing road safety.

Brain-derived neurotrophic factor Val66Met polymorphism moderates the relationship between impulsivity, negative emotions, and binge drinking intensity in university students

Studies on the genetic factors involved in binge drinking (BD) and its associated traits are very rare. The aim of this cross-sectional study was to investigate differences in the association between impulsivity, emotion regulation and BD in a sample of young adults according to the rs6265/Val66Met variant in the brain-derived neurotrophic factor (BDNF) gene, a well-known candidate gene in alcohol use disorders. We recruited 226 university students (112 women), aged between 18 and 25 years old, from two centers in France. The participants completed measures related to alcohol consumption, depression severity, state anxiety levels, impulsivity (UPPS-P), and difficulties in emotion regulation [Difficulty in Emotion Regulation Scale (DERS)]. The relationship between the BD score and the clinical characteristics in the BDNF genotype groups was assessed by partial correlation analyses and moderation analyses. The partial correlation analyses showed that, in the Val/Val genotype group, the BD score was positively related to UPPS-P Lack of Premeditation and Sensation Seeking scores. In the Met carriers group, the BD score was positively related to UPPS-P Positive Urgency, lack of Premeditation, lack of Perseverance and Sensation Seeking scores and to Clarity score of the DERS. Moreover, the BD score was positively associated with depression severity and state anxiety scores. The moderation analyses revealed that BDNF Val/Met genotype moderated the relationship between several clinical variables and BD. The results of the present study support the hypothesis of common and specific vulnerability factors regarding impulsivity and emotion regulation difficulties associated with BD according to this BDNF rs6265 polymorphism.

Are you more risk-seeking when helping others? Effects of situational urgency and peer presence on prosocial risky behavior

Introduction

Prosocial risky behavior (PRB) proposes that individuals take risks for others' benefits or social welfare, and that this may involve trade-offs between risk and social preferences. However, little is known about the underlying cognitive mechanisms of risk-seeking or aversion during PRB.

Methods

This study adopted the dilemma-priming paradigm to examine the interaction between the risk levels of personal cost and situational urgency on PRB (Experiment 1, N  = 88), and it further uncovered the modulation of the risk levels of failure (Experiment 2, N  = 65) and peer presence (Experiment 3, N  = 80) when helping others.

Results

In Experiment 1, the participants involved in risky dilemmas made more altruistic choices for strangers in urgent situations compared to those for strangers in non-urgent situations. However, increasing the risk levels of personal cost decreased the frequencies of help offered to strangers in urgent situations. Experiment 2 further established that, similar to the risk of personal cost, increasing the risk levels of failure when helping others also decreased the frequencies of help offered to strangers in urgent situations. Furthermore, in dilemmas involving a low-risk personal cost, Experiment 3 showed that peer presence encouraged the participants to make more altruistic choices when providing help to strangers in non-urgent situations.

Discussion

Individuals demonstrate obvious risk-seeking behavior when helping others and that both non-urgent situations and peer presence weaken the effect of increased risk aversion on PRB in a limited manner.
