Passive Sensing of Preteens' Smartphone Use: An Adolescent Brain Cognitive Development (ABCD) Cohort Substudy.

Background: Concerns abound regarding childhood smartphone use, but studies to date have largely relied on self-reported screen use. Self-reporting of screen use is known to be misreported by pediatric samples and their parents, limiting the accurate determination of the impact of screen use on social, emotional, and cognitive development. Thus, a more passive, objective measurement of smartphone screen use among children is needed.

From screen time to the digital level of analysis: a scoping review of measures for digital media use in children and adolescents.

Objectives: This scoping review aims to facilitate psychometric developments in the field of digital media usage and well-being in young people by (1) identifying core concepts in the area of "screen time" and digital media use in children, adolescents, and young adults, (2) synthesising existing research paradigms and measurement tools that quantify these dimensions, and (3) highlighting important areas of need to guide future measure development.

Design: A scoping review of 140 sources (126 database, 14 grey literature) published between 2014 and 2019 yielded 162 measurement tools across a range of domains, users, and cultures. Database sources from Ovid MEDLINE, PsycINFO and Scopus were extracted, in addition to grey literature obtained from knowledge experts and organisations relevant to digital media use in children.

Rates of Incidental Findings in Brain Magnetic Resonance Imaging in Children.

Importance: Incidental findings (IFs) are unexpected abnormalities discovered during imaging and can range from normal anatomic variants to findings requiring urgent medical intervention. In the case of brain magnetic resonance imaging (MRI), reliable data about the prevalence and significance of IFs in the general population are limited, making it difficult to anticipate, communicate, and manage these findings.

Objectives: To determine the overall prevalence of IFs in brain MRI in the nonclinical pediatric population as well as the rates of specific findings and findings for which clinical referral is recommended.

From 'screen time' to the digital level of analysis: protocol for a scoping review of digital media use in children and adolescents.

Introduction: Research on the relationship between digital media exposure and child development is complex, inconsistent and fraught with debate. A highlighted area of inadequacy surrounds the methodological limitations of measuring digital media use for both researchers and clinicians, alike. This protocol aims to (1) identify core concepts in the area of screen time and digital media use in children and adolescents (2) map existing research paradigms and screening/measurement tools that serve to underpin and operationalise core concepts and (3) provide an initial step in integrating these findings into a consolidated screening toolkit.

Web-based assessment and brief intervention for alcohol use in women of childbearing potential: a report of the primary findings.

Background: There is a need for more effective assessment and primary prevention programs aimed at accurately measuring and reducing alcohol consumption among women before conception in underserved, high-risk populations. Health information technology may serve this purpose; however, the effectiveness of such tools within this population is not known.

Methods: We conducted a small-scale randomized controlled trial to test the effectiveness of an adapted Web-based alcohol assessment and intervention tool among low-income, nonpregnant women of reproductive age who were receiving Women Infant and Children (WIC) services in San Diego County and who reported currently drinking at a moderate risk level.
