Modeling sensitivity to social threat in adolescent girls: A psychoneurometric approach.

The Research Domain Criteria (RDoC) project's success rests on the assumption that constructs and data can be integrated across units of analysis and developmental stages. We adopted a psychoneurometric approach to establish biobehavioral liability models of sensitivity to social threat, a key component of potential threat that is particularly salient to the development of adolescent affective psychopathology. Models were derived from measures across four units of analysis in a community sample (n = 129) of 11- to 13-year-old girls oversampled for shy/fearful temperament.

"Don't judge me!": Links between in vivo attention bias toward a potentially critical judge and fronto-amygdala functional connectivity during rejection in adolescent girls.

During adolescence, increases in social sensitivity, such as heightened attentional processing of social feedback, may be supported by developmental changes in neural circuitry involved in emotion regulation and cognitive control, including fronto-amygdala circuitry. Less negative fronto-amygdala circuitry during social threat processing may contribute to heightened attention to social threat in the environment. However, "real-world" implications of altered fronto-amygdala circuitry remain largely unknown.

Validating a mobile eye tracking measure of integrated attention bias and interpretation bias in youth.

Introduction: This study sought to validate a real-world speech task designed to assess attention and interpretation bias in an integrated and ecologically valid manner.

Methods: Thirty adolescent girls gave a speech in front of an emotionally ambiguous judge and a positive judge while wearing mobile eye tracking glasses to assess how long they looked at each judge (i.e.

Using a Smartphone App and Clinician Portal to Enhance Brief Cognitive Behavioral Therapy for Childhood Anxiety Disorders.

Cognitive behavioral therapy (CBT) is an efficacious treatment for child anxiety disorders, but 40%-50% of youth do not respond fully to treatment, and time commitments for standard CBT can be prohibitive for some families and lead to long waiting lists for trained CBT therapists in the community. SmartCAT 2.0 is an adjunctive mobile health program designed to improve and shorten CBT treatment for anxiety disorders in youth by providing them with the opportunity to practice CBT skills outside of session using an interactive and gamified interface.

An integrative review of the vigilance-avoidance model in pediatric anxiety disorders: Are we looking in the wrong place?

Enduring cognitive models of anxiety posit that negative biases in information processing are implicated in the etiology, maintenance, and recurrence of anxiety disorders in youth and adults. Specifically, the vigilance-avoidance model of attention is an influential hypothesis proposed to explain anxious individuals' attentional patterns. The vigilance-avoidance model posits that anxious individuals, relative to nonanxious individuals, initially orient more quickly to threatening stimuli and then later avoid threatening stimuli.

Attention to Peer Feedback Through the Eyes of Adolescents with a History of Anxiety and Healthy Adolescents.

During adolescence, youth may experience heightened attention bias to socially relevant stimuli; however, it is unclear if attention bias toward social threat may be exacerbated for adolescents with a history of anxiety. This study evaluated attentional bias during the Chatroom-Interact task with 25 adolescents with a history of anxiety (18F, Mage = 13.6) and 22 healthy adolescents (13F, Mage = 13.

A Longitudinal Follow-up Study Examining Adolescent Depressive Symptoms as a Function of Prior Anxiety Treatment.

Objective: Children who are fearful and anxious are at heightened risk for developing depression in adolescence. Treating anxiety disorders in pre-/early adolescence may be one mechanism through which depressive symptoms later in adolescence can be prevented. We hypothesized that anxious youth who responded positively to cognitive-behavioral therapy (CBT) for anxiety would show reduced onset of depressive symptoms 2 years later compared to treatment nonresponders, and that this effect would be specific to youth treated with CBT compared to an active supportive comparison treatment.

Adolescent Gaze-Directed Attention During Parent-Child conflict: The Effects of Depressive Symptoms and Parent-Child Relationship Quality.

Although dysfunctions in attention have been implicated in the development and maintenance of depression in adults, findings from studies of depressed adolescents have been inconsistent. While some research has shown that youth with depressive symptoms exhibit increased attention to negative stimuli, other findings demonstrated attentional avoidance. Additionally, given the increase in parent-child conflict during adolescence, parent-child relationship quality may be an important moderating factor in the association between depressive symptoms and attention.

Looking for the negative: Depressive symptoms in adolescent girls are associated with sustained attention to a potentially critical judge during in vivo social evaluation.

Attention biases toward negative stimuli are implicated in the development and maintenance of depression. However, research is needed to understand how depression affects attention biases as they unfold in a dynamic social environment, particularly during adolescence when depression rates significantly increase due to enhanced reactivity to social stress. To examine attention biases in a live, socially evaluative environment, 26 adolescent girls from the community gave a speech in front of a potentially critical judge and a positive judge while wearing mobile eye tracking glasses.

The Integration of Functional Brain Activity from Adolescence to Adulthood.

Age-related changes in human functional neuroanatomy are poorly understood. This is partly due to the limits of interpretation of standard fMRI. These limits relate to age-related variation in noise levels in data from different subjects, and the common use of standard adult brain parcellations for developmental studies.

The role of day-to-day emotions, sleep, and social interactions in pediatric anxiety treatment.

Do day-to-day emotions, social interactions, and sleep play a role in determining which anxious youth respond to supportive child-centered therapy (CCT) versus cognitive behavioral therapy (CBT)? We explored whether measures of day-to-day functioning (captured through ecological momentary assessment, sleep diary, and actigraphy), along with clinical and demographic measures, were predictors or moderators of treatment outcome in 114 anxious youth randomized to CCT or CBT. We statistically combined individual moderators into a single, optimal composite moderator to characterize subgroups for which CCT or CBT may be preferable. The strongest predictors of better outcome included: (a) experiencing higher positive affect when with one's mother and (b) fewer self-reported problems with sleep duration.

Anxiety and Gender Influence Reward-Related Processes in Children and Adolescents.

Objective: This study examined the effects of pediatric anxiety and its interaction with gender on reward processes. Based on the purported greater sensitivity to risk in females than males and the propensity for risk aversion in anxiety, clinical anxiety and female gender were hypothesized to act synergistically in reducing reward sensitivity and increasing risk aversion in a pediatric population.

Methods: This hypothesis was tested in two separate experiments using two independent samples.

Age and Social Context Modulate the Effect of Anxiety on Risk-taking in Pediatric Samples.

Although risk-taking has been studied from a developmental perspective, no study has examined how anxiety, age, risk-valence and social context interact to modulate decision-making in youths. This study probes this question using a risk-taking task, the Stunt Task, in clinically anxious children (n = 17, 10 F, age = 8.3-12.

From anxious youth to depressed adolescents: Prospective prediction of 2-year depression symptoms via attentional bias measures.

Anxious youth are at heightened risk for subsequent development of depression; however, little is known regarding which anxious youth are at the highest prospective risk. Biased attentional patterns (e.g.

Emotional and Nonemotional Conflict Processing in Pediatric and Adult Anxiety Disorders.

Objective: Perturbations in emotional conflict adaptation, an implicit regulatory process, have been observed in adult anxiety disorders. However, findings remain inconsistent and restricted to adults. The current study compares conflict adaptation in youth and adults, with and without anxiety disorders.

Mobile technology boosts the effectiveness of psychotherapy and behavioral interventions: a meta-analysis.

We conducted a meta-analysis on the effects of mobile technology on treatment outcome for psychotherapy and other behavioral interventions. Our search of the literature resulted in 26 empirical articles describing 25 clinical trials testing the benefits of smartphone applications, personal digital assistants (PDAs), or text messaging systems either to supplement treatment or substitute for direct contact with a clinician. Overall, mobile technology use was associated with superior treatment outcome across all study designs and control conditions, effect size (ES) = .

Incidental threat during visuospatial working memory in adolescent anxiety: an emotional memory-guided saccade task.

Background: Pediatric anxiety disorders are among the most common psychiatric mental illnesses in children and adolescents, and are associated with abnormal cognitive control in emotional, particularly threat, contexts. In a series of studies using eye movement saccade tasks, we reported anxiety-related alterations in the interplay of inhibitory control with incentives, or with emotional distractors. The present study extends these findings to working memory (WM), and queries the interaction of spatial WM with emotional stimuli in pediatric clinical anxiety.

Robust resting state fMRI processing for studies on typical brain development based on multi-echo EPI acquisition.

Several methodological challenges affect the study of typical brain development based on resting state blood oxygenation level dependent (BOLD) functional MRI (fMRI). One such challenge is mitigating artifacts such as those from head motion, known to be more substantial in younger subjects than older subjects. Other challenges include controlling for potential age-dependence in cerebrospinal fluid (CSF) volume affecting anatomical-functional coregistration; in vascular density affecting BOLD contrast-to-noise; and in CSF pulsation creating time series artifacts.

Oxytocin and vasopressin modulate risk-taking.

The modulation of risk-taking is critical for adaptive and optimal behavior. This study examined how oxytocin (OT) and arginine vasopressin (AVP) influence risk-taking in function of three parameters: sex, risk-valence, and social context. Twenty-nine healthy adults (14 males) completed a risk-taking task, the Stunt task, both in a social-stress (evaluation by unfamiliar peers) and non-social context, in three separate drug treatment sessions.

Low rate of non-attenders to primary care providers in Israel - a retrospective longitudinal study.

Background: A model that combines reactive and anticipatory care within routine consultations has become recognized as a cost-effective means of providing preventive health care, challenging the need of the periodic health examination. As such, opportunistic screening may be preferable to organized screening. Provision of comprehensive preventive healthcare within the primary care system depends on regular attendance of the general population to primary care physicians (PCPs).
