Digital media use frequency, online behaviors, and risk for negative mental health in adolescents in high-achieving schools.

Replicated evidence shows that adolescents enrolled in high-achieving schools exhibit elevated mental health problems relative to national norms, reflecting risk factors such as achievement and social pressures. The frequency of digital media use is similarly a potential risk factor for poor youth mental health, although mediators of this association have not been identified. 2952 youth from three high-achieving U.

Paternal expressed emotion influences psychobiological indicators of threat and safety learning in daughters: A preliminary study.

This preliminary study examined the association of children's anxiety, paternal expressed emotion (EE), and their interaction with psychophysiological indices of children's threat and safety learning. Participants included 24 father-daughter dyads. Daughters (ages 8-13 years, 100% Latina) self-reported their anxiety levels and completed a differential threat conditioning and extinction paradigm, during which psychophysiological responding was collected.

Brain Mechanisms of Attention Orienting Following Frustration: Associations With Irritability and Age in Youths.

Objective: Childhood irritability is a common, impairing problem with changing age-related manifestations that predict long-term adverse outcomes. However, more investigation of overall and age-specific neural correlates is needed. Because youths with irritability exhibit exaggerated responses to frustrating stimuli, the authors used a frustration functional MRI (fMRI) paradigm to examine associations between irritability and neural activation and tested the moderating effect of age.

Association of Digital Media Use With Subsequent Symptoms of Attention-Deficit/Hyperactivity Disorder Among Adolescents.

Importance: Modern digital platforms are easily accessible and intensely stimulating; it is unknown whether frequent use of digital media may be associated with symptoms of attention-deficit/hyperactivity disorder (ADHD).

Objective: To determine whether the frequency of using digital media among 15- and 16-year-olds without significant ADHD symptoms is associated with subsequent occurrence of ADHD symptoms during a 24-month follow-up.

Design, Setting, And Participants: Longitudinal cohort of students in 10 Los Angeles County, California, high schools recruited through convenience sampling.

Anxiety symptoms and children's eye gaze during fear learning.

Background: The eye region of the face is particularly relevant for decoding threat-related signals, such as fear. However, it is unclear if gaze patterns to the eyes can be influenced by fear learning. Previous studies examining gaze patterns in adults find an association between anxiety and eye gaze avoidance, although no studies to date examine how associations between anxiety symptoms and eye-viewing patterns manifest in children.

Latent structure of negative valence measures in childhood.

Background: Internalizing disorders (IDs), consisting of the syndromes of anxiety and depression, are common, debilitating conditions often having onsets in adolescence. Scientists have developed dimensional self-report instruments that assess putative negative valence system (NVS) trait-like constructs as complimentary phenotypes to clinical symptoms. These include various measures that index temperamental predispositions to IDs and correlate with neural substrates of fear, anxiety, and affective regulation.

Test-retest reliability and validity of a frustration paradigm and irritability measures.

Background: Data on the reliability and validity of assessments for irritability, particularly behavioral paradigms, are limited. This study examined the test-retest reliability and validity of a frustration paradigm (the Affective Posner 2 task) and two irritability measures [the Affective Reactivity Index (ARI) and Child Behavior Checklist (CBCL) irritability].

Methods: Participants were 109 youth from a general population sample of twins (aged 9-14 years).

The Inventory of Callous-Unemotional Traits (ICU) in Children: Reliability and Heritability.

Callous-unemotional (CU) traits comprise the core symptoms of psychopathy, yet no study has estimated the heritability of CU traits in a community sample of children using an instrument designed solely to assess CU traits. The current study uses data from 339 twin pairs aged 9-14 to examine the reliability and heritability of the parent-report Inventory of Callous-unemotional Traits (ICU) at two assessments approximately 3 weeks apart. Time-specific measurement error was taken into account to obtain a more accurate estimate of the heritability reflecting the latent liability to CU traits.

Externalizing Outcomes of Youth with and without ADHD: Time-Varying Prediction by Parental ADHD and Mediated Effects.

Although parental attention-deficit/hyperactivity disorder (ADHD) is a risk factor for multiple negative youth outcomes, it is unknown how change in parental ADHD symptoms over time affects change in child ADHD symptoms; moreover, mediators of these predictions are largely unknown. Parents of 230 5-10 year-old children (68 % male) with (n = 120) and without ADHD (n = 110) were followed prospectively for 6-7 years across three separate waves. Parents self-reported their ADHD and depression symptoms and similarly rated offspring ADHD, oppositional defiant disorder (ODD), and conduct disorder (CD) symptoms; youth self-reported their substance use.

The Twin Study of Negative Valence Emotional Constructs.

The Twin Study of Negative Valence Emotional Constructs is a multi-site study designed to examine the relationship between a broad selection of potential measures designed to assess putative endophenotypes for negative valence systems (NVS) and early symptoms of internalizing disorders (IDs). In this article, we describe the sample characteristics, data collection protocols, and measures used. Pre-adolescent Caucasian twin pairs were recruited through the Mid-Atlantic Twin Registry; data collection began in February of 2013.
