Self-report measures offer a unique source of information in the assessment and intervention of individuals with autism spectrum disorder. However, it is not known if children with autism spectrum disorder can answer self-report questionnaires accurately and consistently. As a step to address this issue, we examined validity indexes of the Behavior Assessment System for Children, Second Edition, self-report of personality in 139 children and adolescents with and without autism spectrum disorder aged 8-17 years. There were no significant differences between groups on parents' education, first language spoken at home, intelligence quotient, and age. We examined the influence of diagnosis of autism spectrum disorder, age group, intelligence quotient, and attention problems on the self-report of personality validity indexes (indicators of overly negative or positive, random, inattentive or inconsistent responses). The findings suggest that participants with autism spectrum disorder were more likely to show at least one validity caution on their self-report of personality as compared to their matched typically developing peers. However, this difference might be a result of comorbid attention problems, rather than having a diagnosis of autism spectrum disorder. The diagnosis of autism spectrum disorder was not a significant predictor of the validity indexes. Participants, with and without autism spectrum disorder, with fewer attention problem ratings, higher intelligence quotient scores, and adolescents compared to children showed better validity outcomes.

Despite average or above cognitive and verbal abilities, many children with autism spectrum disorder (ASD) experience difficulties in functional and social communication. Executive functioning (EF) may be the cognitive and regulatory mechanism that underlies these difficulties. Parents rated 92 children with ASD as demonstrating significantly more challenges than 94 typically developing children on measures of EF (Behavior Rating Inventory of Executive Function; BRIEF), functional communication (FC), and verbal conversation (VC) skills. For both groups, the BRIEF metacognition scale emerged as a strong predictor of FC, while the BRIEF behavior regulation and the inhibit scale were predictive of VC skills. These findings suggest that targeting EF domains specifically may improve FC and VC skills in children with ASD.

Parents and professionals are concerned that second language exposure may delay communication in children with ASD. In this study 174 youth (6-16 years) with and without ASD, exposed to a second language, were compared on executive function (EF) and functional communication (FC) with their peers without exposure. There were no significant differences between groups on age, IQ, and socioeconomic status. Parents reported on language exposure and rated EF and FC skills within everyday social contexts. The findings indicated that second language exposure in children with ASD is not associated with delay in cognitive and functional communication skills rather there was evidence of a reduced clinical impact as indexed by a lower percentage of children whose FC and EF ratings fell within the clinical range.

Background: Up to 20% of mothers experience antenatal depression and approximately 30% of these women are treated with serotonergic psychotropic pharmacological therapy during pregnancy. Serotonergic antidepressants readily cross the placenta and the fetal blood-brain barrier, altering central synaptic serotonin signaling and potentially altering serotonin levels in the developing fetal brain. Objective: The aim of this study is to assess the impact of prenatal exposure to serotonergic antidepressants, accounting for maternal mood disturbances, on markers of stress regulation during childhood. Methods: We will follow PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and will search MEDLINE, Embase, CINAHL, PsycINFO, and ClinicalTrials.gov for full-length studies that assessed physiological (eg, cortisol level, heart rate variability, salivary amylase, pupillary size, C-reactive protein) indices of stress regulation in children of pregnant people who were treated with a serotonergic antidepressant at any point during pregnancy. We will assess the quality of observational studies using the Newcastle-Ottawa Scale and the quality of experimental studies using the Cochrane risk-of-bias tool. When possible, we will conduct a random-effects meta-analysis. If meta-analysis is not possible, we will conduct a narrative review. If a sufficient number of studies are found, we will perform subgroup analysis and assess outcomes measured by drug class, dose, trimester of exposure, and child’s age and gender. Results: We registered our review protocol with PROSPERO (International Prospective Register of Systematic Reviews; CRD42021275750), completed the literature search, and initiated title and abstract review in August 2021. We expect to finalize this review by April 2022. Conclusions: Findings should identify the impact of prenatal antidepressant effects on stress regulation and distinguish it from the impact of prenatal exposure to maternal mood disturbances. This review should inform decisions about serotonergic antidepressant use during pregnancy. [ABSTRACT FROM AUTHOR]

Objective: To determine the SARS-CoV-2 seroprevalence among school workers within the Greater Vancouver area, British Columbia, Canada, after the first Omicron wave., Design: Cross-sectional study by online questionnaire, with blood serology testing., Setting: Three main school districts (Vancouver, Richmond and Delta) in the Vancouver metropolitan area., Participants: Active school staff enrolled from January to April 2022, with serology testing between 27 January and 8 April 2022. Seroprevalence estimates were compared with data obtained from Canadian blood donors weighted over the same sampling period, age, sex and postal code distribution., Primary and Secondary Outcomes: SARS-CoV-2 nucleocapsid antibody testing results adjusted for test sensitivity and specificity, and regional variation across school districts using Bayesian models., Results: Of 1850 school staff enrolled, 65.8% (1214/1845) reported close contact with a COVID-19 case outside the household. Of those close contacts, 51.5% (625/1214) were a student and 54.9% (666/1214) were a coworker. Cumulative incidence of COVID-19 positive testing by self-reported nucleic acid or rapid antigen testing since the beginning of the pandemic was 15.8% (291/1845). In a representative sample of 1620 school staff who completed serology testing (87.6%), the adjusted seroprevalence was 26.5% (95% CrI 23.9% to 29.3%), compared with 32.4% (95% CrI 30.6% to 34.5%) among 7164 blood donors., Conclusion: Despite frequent COVID-19 exposures reported, SARS-CoV-2 seroprevalence among school staff in this setting remained no greater than the community reference group. Results are consistent with the premise that many infections were acquired outside the school setting, even with Omicron., Competing Interests: Competing interests: CO'R is an employee of the Vancouver School District, but the latter was not involved in the design, analysis, interpretation of data or the drafting of this manuscript.
