Multivariate Assessment of Inhibitory Control in Youth: Links With Psychopathology and Brain Function.

Inhibitory control is central to many theories of cognitive and brain development, and impairments in inhibitory control are posited to underlie developmental psychopathology. In this study, we tested the possibility of shared versus unique associations between inhibitory control and three common symptom dimensions in youth psychopathology: attention-deficit/hyperactivity disorder (ADHD), anxiety, and irritability. We quantified inhibitory control using four different experimental tasks to estimate a latent variable in 246 youth (8-18 years old) with varying symptom types and levels. Participants were recruited from the Washington, D.C., metro region. Results of structural equation modeling integrating a bifactor model of psychopathology revealed that inhibitory control predicted a shared or general psychopathology dimension, but not ADHD-specific, anxiety-specific, or irritability-specific dimensions. Inhibitory control also showed a significant, selective association with global efficiency in a frontoparietal control network delineated during resting-state functional magnetic resonance imaging. These results support performance-based inhibitory control linked to resting-state brain function as an important predictor of comorbidity in youth psychopathology.

Translating Big Data to Clinical Outcomes in Anxiety: Potential for Multimodal Integration.

PURPOSE OF THE REVIEW: This review describes approaches to research on anxiety that attempt to link neural correlates to treatment response and novel therapies. The review emphasizes pediatric anxiety disorders since most anxiety disorders begin before adulthood. RECENT FINDINGS: Recent literature illustrates how current treatments for anxiety manifest diverse relations with a range of neural markers. While some studies demonstrate post-treatment normalization of markers in anxious individuals, others find persistence of group differences. For other markers, which show no pretreatment association with anxiety, the markers nevertheless distinguish treatment-responders from non-responders. Heightened error related negativity represents the risk marker discussed in the most depth; however, limitations in measures related to error responding necessitate multimodal and big-data approaches. Single risk markers show limits as correlates of treatment response. Large-scale, multimodal data analyzed with predictive models may illuminate additional risk markers related to anxiety disorder treatment outcomes. Such work may identify novel targets and eventually guide improvements in treatment response/outcomes.

Social-Emotional Attention in School-Age Children: A Call for School-Based Intervention during COVID-19 and Distance Learning.

Early research indicates that the COVID-19 pandemic and subsequent regulations put children at increased risk of negative mood, anxiety, attention difficulties, and social challenges. Concordantly, these difficulties also are associated with deficits in social-emotional attention in children. On a daily basis, students are required to process and respond to a large amount of complex social-emotional information, including attending to teachers and interacting with peers. These attentional demands and associated stressors have increased as students are required to stare at computer screens during online learning as a result of COVID-19 restrictions. However, there is a dearth of research that investigates the role of social and emotional information on attention in children. The present study assessed the effects of social relevance and emotional valence on attentional demands in children and how functioning is related to individual differences in symptoms and deficits that may be exacerbated by the COVID-19 pandemic. Results show that social and emotional information affect attention in children. Task performance also was associated with negative mood, social stress, and attention focus. This study highlights the need for school-based distance learning interventions to help ameliorate negative social-emotional risks of the COVID-19 pandemic in children. Potential effective avenues include mindfulness-based interventions and attention bias modification training.

Evaluating the development and well-being assessment (DAWBA) in pediatric anxiety and depression.

Enhancing screening practices and developing scalable diagnostic tools are imperative in response to the increasing prevalence of youth mental health challenges. Structured lay psychiatric interviews have emerged as one such promising tool. However, there remains limited research evaluating structured psychiatric interviews, specifically their characterization of internalizing disorders in treatment-seeking youth. This study evaluates the relationship between the Development and Well-Being Assessment (DAWBA), a structured psychiatric interview, and established measures of pediatric anxiety and depression, including the Screen for Child Anxiety Related Disorders (SCARED), the Pediatric Anxiety Rating Scale (PARS), and the Mood and Feelings Questionnaire (MFQ). The study comprised two independent clinical samples of treatment-seeking youth: sample one included 55 youth with anxiety and 29 healthy volunteers (HV), while sample two included 127 youth with Major Depressive Disorder and 73 HVs. We examined the association between the DAWBA band scores, indicating predicted risk for diagnosis, the SCARED and PARS (sample one), and the MFQ (sample two). An exploratory analysis was conducted in a subset of participants to test whether DAWBA band scores predicted the change in anxiety symptoms (SCARED, PARS) across a 12-week course of cognitive behavioral therapy. The results revealed that the DAWBA significantly predicted the SCARED, PARS and MFQ measures at baseline; however, it did not predict changes in anxiety symptoms across treatment. These findings suggest that the DAWBA may be a helpful screening tool for indexing anxiety and depression in treatment-seeking youth but is not especially predictive of longitudinal trajectories in symptomatology across psychotherapy.

Attention control ability, mood state, and emotional regulation ability partially affect executive control of attention on task-irrelevant emotional stimuli.

Executive control of attention is important for goal-directed behavior, and it is influenced by emotional information. This study examined the effect of stimulus valence on a color word flanker task and how individual differences within a general population may affect task performance. 119 participants completed a color word flanker task with task-irrelevant emotional information (positive, negative, neutral). This task was followed by several self-report scales that measured individual differences in attention control ability (ACS), current mood (PANAS), and emotion regulation ability (DERS). Faster reaction times and greater accuracy were associated with negative stimuli. The flanker effect was greater for negative trials than for neutral and positive trials. The greater flanker effect for negative trials was driven by decreased reaction time on negative congruent trials. A significant interaction was evident between stimulus valence and ACS score, such that reaction time was faster for negative trials than for neutral trials among those with low, average, and high ACS. However, this difference was largest for those with high ACS. Further, these relationships between attention control ability and executive control of attention were influenced by level of depressive symptoms (as measured by BDI-II). This study extends our knowledge about the relationship between executive control of attention to emotional stimuli and individual differences related to mood and attentional disorders in a general population. Study results may have important implications for theoretical models of cognitive control and task-irrelevant emotional information across individual differences.
