Background: Clinical presentations of child and adolescent psychopathology can vary systematically for boys and girls. While network analysis is increasingly being applied to explore gender differences in psychopathology among adults, there is a dearth of network studies considering differences in symptoms for boys and girls, particularly in developmental trauma-related symptomatology. Methods: This study involves rural children (n = 375, 39.47% girls) and adolescents (n = 291, 51.20% girls) involved with child protection services in Ontario, Canada. Caregivers completed the Assessment Checklist for Children or Adolescents within the first six months of care. Psychometric network analyses were conducted using subscales for boys and girls. Gender differences were examined via network comparison permutation tests, moderated network models, and independent t-tests.Results: Attachment-related interpersonal difficulties were the most central nodes in the child and adolescent networks for both boys and girls. Emotional dysregulation also had high strength centrality for adolescents. While network comparison tests found the overall network structures and global network strength to be invariant between genders for children and adolescents, moderated network models and independent t-tests revealed several gender differences with regards to the expression of various symptoms. Among children, girls exhibited more indiscriminate and pseudomature interpersonal behaviors, whereas boys expressed significantly more non-reciprocal interpersonal behaviors and self-injury. Adolescent girls exhibited more behavioral dysregulation and suicide discourse in the moderated network model; t-tests also indicated higher levels of emotional dysregulation, negative self-image, and other items.Discussion: This study supports evidence of gender differences in the expression of complex trauma symptomatology among girls and boys across development, including that girls tend to exhibit more symptoms. Findings demonstrate the primacy of attachment-specific difficulties and emotion dysregulation, consistent with the transdiagnostic conceptualization of the consequences of developmental trauma.

IntroductionIn the early stages of the COVID-19 pandemic, most Canadian provinces and territories enacted public health measures to reduce virus spread, leading most child care centers across the country to limit or halt in-person service delivery. While it is broadly known that the range of activities available to children and youth reduced drastically as a result, research has yet to explore if and how children's activities shifted in relation to changes in child care arrangements.MethodChildren's activities during the early months of the pandemic were assessed based on parent-report data (n = 19,959). Activity patterns were extracted via latent profile analysis. Thereafter, differences in child-care related outcomes across profiles were compared via logistic regression models.ResultsLatent profile analysis yielded three distinct activity patterns: Screenies (91.5%) were children who engaged in high amounts of screen use relative to all other activities; Analog children (3.1%) exhibited mostly off-screen activities (e.g., reading, physical exercise); and children in the Balanced group (5.4%) appeared to pursue a wide variety of activities. Children were more likely to fall into the Screenies or Balanced profiles when caregivers reported changes in child care arrangements. Moreover, parents of children with Balanced activity profiles were more likely to be planning to use child care when services reopened post-pandemic, compared to parents of children in the Analog group.DiscussionThe present findings call attention to heterogeneity in children's activities during COVID-19, which should be considered in the context of pandemic-related child care closures. Implications for children, families, and child care services during and beyond COVID-19 are discussed.
