Integrating behavioral health services within pediatric primary care may help address barriers to these services for youth, especially the underserved. Models of primary care behavioral health include coordinated, colocated, integrated, and collaborative care. This study began exploring the comparative utility of these models by investigating differences in the demographics and diagnoses of patients seen for a behavioral health warm handoff (integrated model) and a scheduled behavioral health visit (colocated model) across 3 pediatric primary care sites.

DNA exhibits many attractive properties, such as programmability, precise self-assembly, sequence-coded biomedical functions, and good biocompatibility; therefore, DNA has been used extensively as a building block to construct novel nanomaterials. Recently, studies on oligonucleotide-polymer conjugates (OPCs) have attracted increasing attention. As hybrid molecules, OPCs exhibit novel properties, e.

Silica coated gold nanorods (GNRs@SiO) with dumbbell-like morphology allowing dual functionalization in an individual nanostructure have attracted great attention for applications such as sensing and biological imaging. We report a detailed study on the feasibility of controlling the morphology of silica coating on GNRs. The morphology of the silica shell can be either cylindrical or dumbbell shaped.

This paper describes the rationale, design, and methods of the Treatment for Anxiety in Autism Spectrum Disorders study, a three-site randomized controlled trial investigating the relative efficacy of a modular CBT protocol for anxiety in ASD (Behavioral Interventions for Anxiety in Children with Autism) versus standard CBT for pediatric anxiety (the program) and a treatment-as-usual control. The trial is distinct in its scope, its direct comparison of active treatments for anxiety in ASD, and its comprehensive approach to assessing anxiety difficulties in youth with ASD. The trial will evaluate the relative benefits of CBT for children with ASD and investigate potential moderators (ASD severity, anxiety presentation, comorbidity) and mediators of treatment response, essential steps for future dissemination and implementation.

Social phobia (SoP) in youth may manifest differently across development as parent involvement in their social lives changes and social and academic expectations increase. This cross-sectional study investigated whether self-reported and parent-reported functioning in youth with SoP changes with age in social, academic, and home/family domains. Baseline anxiety impairment data from 488 treatment-seeking anxiety-disordered youth (ages 7-17, N = 400 with a SoP diagnosis) and their parents were gathered using the Child Anxiety Impact Scale and were analyzed using generalized estimating equations.

The present study examined the psychometric properties, including discriminant validity and clinical utility, of the youth self-report and parent-report forms of the Multidimensional Anxiety Scale for Children (MASC) among youth with anxiety disorders. The sample included parents and youth (N = 488, 49.6% male) ages 7 to 17 who participated in the Child/Adolescent Anxiety Multimodal Study.

Guidelines for conducting effective exposure treatment with anxious youth emphasize preparation for and processing of the exposure task as important elements, but limited research has examined these guidelines. Using multiple regression, this study evaluated the extent to which independent observers' ratings of preparation and processing of in-session exposure tasks were associated with treatment outcome in a sample of 61 anxiety-disordered youth. Results indicated that preparation for exposure was not related to outcome, but postevent processing of the exposure task was significantly associated with clinician-rated diagnostic improvements.
