Preadolescent sensation seeking and early adolescent stress relate to at-risk adolescents' substance use by age 15

Test-Retest Reliability of Self-Reported Substance Use and Sexual Risk Behavior Among at-Risk Adolescents

Adolescents often engage in behaviors such as substance use and risky sexual activity that can lead to negative health and psychological consequences for themselves and others. Accurate measurement of these behaviors in surveys is challenging given that the behaviors are often viewed as undesirable and/or are illegal, so it is important to test the psychometric properties of instruments used to assess adolescent risk behaviors. The current study aimed to assess the test-retest reliability of a widely used measure of youth risk-taking behavior, the Youth Risk Behavior Survey (YRBS). A sample of 156 at-risk adolescents aged 16-18 years (81% male; 61% White) completed the YRBS retrospectively across intervals ranging from 3 to 12 days during their stay in a residential program at which they were under close supervision and had limited ability to engage in new risk behaviors. Participants were asked to complete the YRBS based on their "typical" (pre-program) behavior at both administrations, which were 10-14 weeks into their stay. The reliability of responses was assessed using kappa and weighted kappa analyses. Findings indicate moderate to substantial reliability for nearly all items, suggesting that at-risk youth reliably reported their engagement in health risk behaviors across multiple administrations and supporting the psychometric strength of the YRBS measure for use with this population.

The age-varying effects of adolescent stress on impulsivity and sensation seeking

Adolescence is defined in part by heightened exposure and sensitivity to stressors. In a longitudinal cohort of youth at risk for substance use problems, we examined the age-varying relationship between stress exposure and traits that are central to the dual systems model. The positive associations between stress exposure, impulsivity, sensation seeking varied as function of age. Specifically, the influence of stress exposure on impulsivity strengthened during early adolescence and remained stable into early adulthood, while the influence of stress exposure on sensation seeking strengthened from early- to mid-adolescence and weakened thereafter. These findings suggest that the maturational imbalance between the capacity to regulate impulsive tendencies and sensation seeking may be exaggerated for youth who are exposed to a high number of stressors.

Cumulative Stressors and Adolescent Substance Use: A Review of 21st-Century Literature

The aim of this review is to assess empirical studies from the last 2 decades that have examined the association between cumulative stressors and adolescent substance use. Cumulative stressors were measured in these studies with adverse childhood experiences or adolescent stressful life events inventories. The 109 articles meeting the eligibility criteria that emerged from the review demonstrated a consistent, yet modest, association between cumulative stressors and adolescent substance use. Of note, several studies found that the associations were moderated or mediated by genetic factors related to cortisol regulation, intrapersonal factors such as low self-control, or interpersonal factors such as peer substance use. The review's findings thus suggest that efforts to reduce the effects of cumulative stressors on substance use could gainfully identify and target these risk moderators and mediators.

Do Trajectories of Sensation Seeking Vary by Sex and Child Maltreatment Subtypes?

Child maltreatment and elevated sensation seeking are associated with a wide range of negative outcomes. Longitudinal data from a study of Puerto Ricans living in two sociocultural contexts were used to determine whether child maltreatment subtypes, sex, or sociocultural context relate to trajectories of sensation seeking. Participants were 2,489 individuals from the Boricua Youth Study (48.5% girls) living in New York and in Puerto Rico (PR; 5-15 years old at Wave 1). Subtypes of child maltreatment were measured using child report on the Parent-Child Conflict Tactics Scale and the Sexual Victimization Scale at Wave 1. The association between child maltreatment subtypes, sex, sociocultural context, and previously established sensation-seeking trajectories across three waves of data collection was probed using multinomial logistic regression. Girls, but not boys, who experienced neglect (adjusted odds ratio; AOR; 95% confidence interval [95% CI] = 5.33 [1.35, 21.03]), or physical abuse (AOR [95% CI] = 3.66 [1.07, 12.54]), were more likely to have an elevated sensation-seeking trajectory than a normative trajectory. For boys, none of the maltreatment subtypes were linked to the elevated sensation-seeking class. Girls exposed to verbal abuse (AOR [95% CI] = 0.33 [0.15, 0.75]) and boys exposed to physical abuse (AOR [95% CI] = 0.39 [0.16, 0.97]) were less likely to belong to the low sensation-seeking class. No significant interactions between sociocultural context (i.e., PR vs. New York) and maltreatment subtype on the development of sensation seeking were found. This research suggests sensation-seeking levels vary by experiences of childhood maltreatment, and that sex moderates the relationship between child maltreatment experiences and sensation seeking, with an association between some maltreatment subtypes and elevated sensation-seeking trajectories found in girls, but not boys. These results underline the importance of considering sex when examining how child maltreatment relates to outcomes.

School-based interventions for preventing substance use in indigenous children ages 7-13: a scoping review protocol

INTRODUCTION

Throughout the world, indigenous peoples share traumatic colonial experiences that have caused gross inequalities for them and continue to impact every aspect of their lives. The effect of intergenerational trauma and other health disparities have been remarkable for Indigenous children and adolescents, who are at a greater risk of adverse mental health and addiction outcomes compared with non-indigenous people of the same age. Most indigenous children are exposed to addictive substances at an early age, which often leads to early initiation of substance use and is associated with subsequent physical and mental health issues, poor social and relational functioning, and occupational and legal problems. The aim of this paper is to report the protocol for the scoping review of school-based interventions for substance use prevention in Indigenous children ages 7-13 living in Canada, the USA, Australia and New Zealand. This scoping review seeks to answer the following questions: (1) What is known about indigenous school-based interventions for preventing substance use and (2) What are the characteristics and outcomes of school-based interventions for preventing substance use?

METHODS AND ANALYSIS

This scoping review will use steps described by Arksey and O'Malley and Levac: (1) identifying the research question(s); (2) identifying relevant studies; (3) selecting the studies; (4) charting the data; (5) collating, summarising and reporting the results and (6) consulting with experts. Our findings will be reported according to the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

ETHICS AND DISSEMINATION

Ethics review approval is not required for this project. Findings from this study will be presented to lay public, at scientific conferences and published in a peer-reviewed journal.

Sensation seeking in 3- to 6-year-old children: associations with socio-demographic parameters and behavioural difficulties

BACKGROUND

The present study investigates whether sensation seeking in pre-school-age children is associated with age, gender and socio-economic status, and how sensation seeking relates to behavioural difficulties.

METHODS

The study sample consisted of 423 three- to six-year-old children whose parents had completed questionnaires on the children's sensation seeking (Sensation Seeking Scale for Young Children), socio-economic status, and behavioural difficulties (Strengths and Difficulties Questionnaire). Multiple linear regression models were applied to investigate associations between sensation seeking and age, gender, socio-economic status and behavioural difficulties.

RESULTS

Sensation seeking was significantly higher in male vs. female children but not associated with children's socio-economic status. Furthermore, sensation seeking was positively correlated with conduct problems, but negatively with emotional symptoms and peer-relationship problems.

CONCLUSION

These results replicate findings in adults and strengthen the assumption that sensation seeking is a personality trait that is already observable in early childhood. Furthermore, our results suggest relationships between higher levels of sensation seeking and externalising behaviour as well as relationships between lower levels of sensation seeking and internalising behaviour.

Longitudinal development of risk-taking and self-injurious behavior in association with late adolescent borderline personality disorder symptoms

Self-injurious behavior and risk-taking behaviors are associated with adolescent borderline personality disorder (BPD). Developmental trajectories of self-injurious and risk-taking behavior in predicting BPD have not been fully understood. The aim of the present study was to examine self-injurious and risk-taking behavior development and their prospective influence on BPD symptoms in adolescence. Data (n = 506; 62.06 % females, 14.53 years) from the German Saving and Empowering Young Lives in Europe cohort were analyzed. Self-injurious and risk-taking behaviors were assessed at baseline and one-year follow-up. BPD symptoms were assessed at two-year follow-up. In fully adjusted stepwise binominal regression analyses, recent onset, termination and maintenance of risky alcohol use and self-injurious behavior remained as significant predictors of BPD. Highest ORs were found for alcohol termination and maintenance of self-injurious behavior. Other facets of risk-taking behavior were not associated with increased ORs of BPD symptoms at two-year follow-up. These findings highlight the importance of self-injurious behavior and specific facets of risk-taking behavior in the development of adolescent BPD. Clinicians should focus on efforts in preventing adolescents from risk-taking and self-injurious behavior, since engaging in young age and therefore in potentially longer periods of these behaviors is associated with the highest risk of BPD.

The Interactive Effects of Parental Knowledge with Impulsivity and Sensation Seeking in Adolescent Substance Use

This study examined whether interactions of parental knowledge of adolescent's whereabouts with impulsivity and sensation seeking in the prediction of adolescent substance use supported the diathesis-stress or differential susceptibility model in 230 15-year old adolescents (53% girls). Interactions between impulsivity and parental knowledge supported the diathesis-stress model with high impulsivity as a vulnerability factor: when impulsivity was higher, low levels of parental knowledge were associated with higher levels of substance use. Interactions between sensation seeking and parental knowledge supported differential susceptibility with low sensation seeking as a susceptibility factor; low parental knowledge was associated with higher substance use and high parental knowledge with lower substance use when sensation seeking was lower. Our results show that impulsivity and sensation seeking should be considered independently. Results support previous research suggesting that impulsivity in adolescence may act as a vulnerability factor and suggests that low sensation seeking may be a susceptibility factor.

The impact of stress latent class membership and transitions on statutory service and alcohol use in adolescents across 33 months

INTRODUCTION

Adolescence is a period of intense physical, biological, and psychological change, and this can result in feelings of stress. We examined the development of stress in early adolescence, and further, how that development impacted on both alcohol-use behaviours and utilisation of government-provided services.

METHODS

We used a shortened, 24-item version of the Adolescent Stress Questionnaire (ASQ) to account for stress, and applied latent transition analysis to examine longitudinal change. Participants were 2230 school children (M_age = 12.5 years at time one) in Northern Irish and Scottish schools who completed a battery of questionnaires 33 months apart.

RESULTS

We identified three stress profiles at baseline and 33 months: (a) High Stress, (b) Typical Stress, and (c) Low Stress. Stress profiles were shown to be associated with, and predict, a theoretically consistent set of outcomes, where adolescents who experienced high levels of stress also suffered from both problematic alcohol behaviours and harms, and utilised services.

CONCLUSIONS

Future studies are recommended to include more exploration into the usefulness of a multivariate conceptualising of ASQ-S scores.

The long-term cognitive consequences of adolescent exposure to recreational drugs of abuse

During adolescence, the brain continues to undergo vital developmental processes. In turn, complex behavioral and cognitive skills emerge. Unfortunately, neurobiological development during adolescence can be influenced by environmental factors such as drug exposure. Engaging in drug use during adolescence has been a long-standing health concern, especially how it predicts or relates to drug using behavior later in life. However, recent findings suggest that other behavioral domains, such as learning and memory, are also vulnerable to adolescent drug use. Moreover, it is becoming increasingly apparent that deficits in learning and memory following adolescent drug use endure into adulthood, well after drug exposure has subsided. Although persistent effects suggest an interaction between drug exposure and ongoing development during adolescence, the exact acute and long-term consequences of adolescent drug exposure on substrates of learning and memory are not fully understood. Thus, this review will summarize human and animal findings on the enduring cognitive deficits due to adolescent drug exposure. Moreover, due to the fact that adolescents are more likely to consume drugs of abuse legally available to adults, this review will focus on alcohol, nicotine, and marijuana. Further, given the critical role of the frontal cortex and hippocampus in various learning and memory domains, the impact adolescent use of the previous listed drugs on the neurobiology within these regions will also be discussed.

The Moderating Role of Spirituality in the Association between Stress and Substance Use among Adolescents: Differences by Gender

Adolescents are exposed to various stressors that may increase the risk for substance use. Due to the detrimental, and potentially long-lasting, effects related to substance use, it is necessary to explore more optimal coping strategies. This study explored the association between substance use and stress among male and female high school students in relation to spirituality as a moderator. To examine these relationships, the study used cross-sectional data collected from 27,874 high school students (Male = 50.7%, Female = 49.3%) across 58 high schools in Maryland that included an ethnically diverse sample (49% Caucasian, 30% African American) with an average age of 16 years old. Bivariate results showed differences in substance use, stress, and spirituality between male and female students. Higher rates of substance use were generally found among male students compared to female students; rates tended to be higher among female students for stress and spirituality compared to their male counterparts. Multilevel analyses indicated a positive association between stress and substance use among male and female students after adjusting for demographic and school-level factors. Both male and female students who reported turning to spiritual beliefs when experiencing problems were less likely to use substances. However, the interaction between stress and spirituality was significant for males only. These findings suggest that stress may increase the propensity for substance use and that spirituality might be a viable coping mechanism useful for helping high school students adapt to stressful circumstances and situations.
