There is one clinical trial.
Clinically significant anxiety affects up to 20% of preschool-aged children and often fails to respond to currently available treatments. Emerging science suggests that increasing brain capacity for "effortful control" (EC) may help anxious children to regulate emotion and behavior to improve outcomes. Thus, in the proposed study, children will be trained on EC tasks (including selective attention, response inhibition, etc.) to increase capacity for effortful control (EC) over fear behaviors. To determine whether EC training improves brain capacity to regulate fear, investigators will assess neurophysiological and behavioral indices of effortful control and fear reactivity before and after this training.
Description: Error-related negativity (ERN) is assessed through the "Zoo task", a "Go/No-Go" paradigm assessing effortful control. Children view a series of animals on a computer screen and are asked to press a button when a new animal appears (Go trials), unless the animal is an orangutan (i.e., inhibit button response, No-Go trials). The task includes 8 blocks, each containing 30 unique animals (Go trials) and 10 orangutans (No-Go trials) in random order. Event related potentials (ERP; direct responses to stimuli measured using electroencephalography) will be examined from fronto-central recording sites time-locked to error and correct response. Differentiation between these trial types is the primary ERN measure, but ERN in error trials will also be considered, as well as ERPs in correct trials. The number of No-Go errors and response times (RTs) to Go trials will also be considered in analyses, as performance can affect ERN amplitude.Measure: Change from Baseline Error Related Negativity (ERN) at Post-Intervention Time: approximately 10 weeks
Description: Preschool participants watch age appropriate film clips (four fearful, four neutral, and four happy clips). White noise bursts are presented at varying time points to elicit the startle eyeblink response (FPS), recorded from two electrodes under the left eye.Measure: Change from Baseline Fear Potentiated Startle (FPS) at Post-Intervention Time: approximately 10 weeks
Description: Assessed using the Spence Anxiety Scale for Preschoolers (Spence, Rapee, McDonald, & Ingram, 2001). This 34-item parent-report scale provides an overall measure of child anxiety.Measure: Change in Anxiety Symptoms Time: approximately 10 weeks

An HTML report was created for each of the unique drugs, MeSH, and HPO terms associated with COVID-19 clinical trials. Each report contains a list of either the drug, the MeSH terms, or the HPO terms. All of the terms in a category are displayed on the left-hand side of the report to enable easy navigation, and the reports contain a list of correlated drugs, MeSH, and HPO terms. Further, all reports contain the details of the clinical trials in which the term is referenced. Every clinical trial report shows the mapped HPO and MeSH terms, which are also hyperlinked. Related HPO terms, with their associated genes, protein mutations, and SNPs are also referenced in the report.Drug Reports MeSH Reports HPO Reports
