Examining the Bidirectional Associations Between Sleep Duration, Screen Time, and Internalizing Symptoms in the ABCD Study.

PURPOSE: The likelihood of meeting sleep duration and screen time guidelines decreases as children develop toward adolescence. Simultaneously, the prevalence of internalizing symptoms increases. The purpose of this paper was to examine the bidirectional associations between sleep duration and screen time with internalizing symptoms in a one-year longitudinal study starting in late childhood. METHODS: Participants were 10,828 youth (47.8% female) enrolled in the Adolescent Brain Cognitive Development Study. At baseline (mean age 9.9 years) and one-year follow-up (mean age 10.9 years), youth self-reported screen time for weekdays and weekend days. Responses were separately dichotomized as >2 versus ≤2 hours/day (meeting behavioral guidelines). Caregiver-reported youth sleep duration was dichotomized as <9 versus 9-11 hours/night (meeting behavioral guidelines). Caregivers reported internalizing symptoms via the child behavior checklist. The withdrawn/depressed, anxious/depressed, and somatic symptom child behavior checklist subscale t-scores were separately dichotomized as ≥65 (borderline clinical levels of symptoms and above) versus <65. Analyses were gender-stratified. RESULTS: In females, longer baseline sleep duration was protective against withdrawn/depressed symptoms (odds ratio [OR] 0.6, 95% confidence interval [CI] 0.4-0.8) and somatic complaints (OR 0.8, 95% CI 0.6-0.97) one year later. In females, greater baseline weekend screen time was associated with increased risk of withdrawn/depressed symptoms (OR 1.6, 95% CI 1.1-2.2) one year later. No other significant associations were observed. DISCUSSION: Longitudinal associations between sleep duration, weekend screen time, and internalizing symptoms were unidirectional (behavior preceding internalizing symptoms), among females only, and specific to withdrawn/depressed and somatic symptoms. These prospective study findings warrant attention and inform future research in this cohort.

Emerging research areas and contributions of NIH in violence research across the lifespan and throughout different settings.

This commentary provides background for NIH's interest in research designed to better understand the causes and consequences of violence and the development, evaluation, and implementation of preventive and treatment interventions to address the resulting trauma, injuries, and mortality from violence. The manuscript describes the context that contributed to a range of initiatives from the NIH focused on violence research, with a particular emphasis on firearms violence prevention research, and opportunities and gaps for future research.

Efforts to advance NIH-funded behavioral and social sciences research on structural racism and health.

This commentary provides background and context for the increasing attention to research designed to better understand and address the impact of structural racism on health, with particular attention to the role of the behavioral and social sciences. The manuscript describes the impetus provided to this work by recent public health crises of COVID-19 and the racial justice movement that emerged following the murder of George Floyd in the summer of 2020. A range of initiatives from the National Institutes of Health (NIH) focused on structural racism and health equity are discussed in this context and opportunities and gaps for future research are identified.

Providing Incentives to Youth Participants in Research: A Literature Review.

The provision of financial incentives to youth involved in research remains an understudied and contentious issue. Although the practice is common and often accepted, a comprehensive understanding of the current status of the literature regarding the potential benefits and limitations is lacking. The primary question this article seeks to answer is as follows: "What are the concerns and best practices identified in the literature for the appropriate and ethical provision of incentives to children and adolescents?" Following a thorough review and screening process, 25 articles were selected and central themes were identified within them. Themes include the following: the wage-payment model, effectiveness for recruitment, effectiveness for retention, financial versus alternative incentives, coerciveness, influence on validity of results, and other ethical dilemmas. Gaps in the literature are discussed. Overall, the literature suggests financial incentives can be provided appropriately to children as long as necessary precautions are taken.

Victim Offender Overlap: Dual Trajectory Examination of Victimization and Offending among Young Felony Offenders over Seven Years.

The relationship between victimization and offending has been shown consistently across different samples, settings, and crime types. This study uses data from the Pathways to Desistance Study to examine dual trajectories of offending between the ages of 15 and 24 in a sample of male felony offenders. The dual trajectory models demonstrate substantial convergence in victimization and offending. And while there are sizable numbers of youth who continue to be victimized, but desist or decrease in their offending behaviors, very few youth continue to offend in the absence of continued victimization. This study also proposes and tests three criminological theories that have been employed as explanations for the victim-offender overlap - low self-control, lifestyles/routine activities, and street-code attitudes. The logistic regression results indicate that involvement in risky and/or unstructured, unsupervised activities is a key correlate of the victim-offender overlap. The strength of the relationship between routine activity variables and the victim-offender overlap supports the provision of structured, supervised activities for youth and young adults as a way of preventing future victimization and offending, particularly among youth who have high exposure to violence.

Teen dating violence: building a research program through collaborative insights.

The National Institute of Justice (NIJ) has an emerging portfolio of research in the area of teen dating violence (also known as adolescent relationship abuse). This article begins with a discussion of the developments that prompted NIJ to focus on teen dating violence. Next, the article highlights specific accomplishments and contributions that NIJ has made to helping develop knowledge and scientific understanding of adolescent relationship abuse, particularly around the prevention of teen dating violence perpetration and victimization. This is followed by a presentation of some of the key findings from NIJ-funded research. We then move to a discussion of some of the complex issues around definition, measurement and research methods and how NIJ has been involved in addressing those issues. The article concludes with some thoughts about the intersection of teen dating violence research, policy, and practice and highlights several research gaps that are in need of additional attention.
