Background Good quality friendships and relationships are critical to the development of social competence and are associated with quality of life and mental health in childhood and adolescence. Through social distancing and isolation restrictions, the COVID‐19 pandemic has had an impact on the way in which youth socialize and communicate with friends, peers, teachers and family on a daily basis. In order to understand children's social functioning during the pandemic, it is essential to gather information on their experiences and perceptions concerning the social changes unique to this period. The objective of this study was to document children and adolescents' perspectives regarding their social life and friendships during the COVID‐19 pandemic, through qualitative interviews. Methods Participants ( N = 67, 5–14 years) were recruited in May and June 2020. Semi‐structured interviews were conducted via a videoconferencing platform. A thematic qualitative analysis was conducted based on the transcribed and coded interviews (NVivo). Results The upheavals related to the pandemic provoked reflection among the participants according to three main themes, each of which included sub‐themes: (1) the irreplaceable nature of friendship, (2) the unsuspected benefits of school for socialization and (3) the limits and possibilities of virtual socialization. Conclusions The collection of rich, qualitative information on the perspectives of children and adolescents provides a deeper understanding of the consequences of the pandemic on their socialization and psychological health and contributes to our fundamental understanding of social competence in childhood.

Objective: To report preliminary empirical data on a novel, developmentally appropriate, observational postconcussive symptoms inventory for infants, toddlers, and preschoolers. Setting: Emergency departments of 2 tertiary, urban pediatric hospitals. Participants: Ninety-eight children (0-8 years of age; mean age at injury = 33.00, SD = 24.7 months) with mild traumatic brain injury (concussion) divided into younger (0-2 years) and older (3-8 years) age groups. Design: Observational study. Main Measure: The Report of Early Childhood Traumatic Injury Observations & Symptoms (REACTIONS) documents 17 postconcussive symptoms representing observable manifestations thereof and was completed by parents in the acute (24-48 hours; n = 65), subacute (7-14 days; n = 78), and/or persistent phase (25-35 days; n = 72) post-mild traumatic brain injury. Results: Different patterns of postconcussive symptoms were reported by age group, with behavioral manifestations particularly salient in younger children. More children younger than 2 years had sleep and comfort-seeking symptoms at each of the 3 postinjury time points. Conclusion: Postconcussive symptoms may manifest differently after mild traumatic brain injury sustained during early childhood. To fully understand and address their presence and evolution, developmentally sound measures such as the REACTIONS inventory are required.
