Identifying Children and Adolescents at Elevated Mental Health Risk Before and During COVID-19

To determine whether the prevalence of psychosocial risk in children and adolescents changed from before to during the COVID-19 pandemic and whether these changes differed by age group, sex, and season, based on a standardized psychosocial measure completed as a routine part of primary care.

Children and adolescents aged 5.5 to 17.9 years were screened with a parent report Pediatric Symptom Checklist-17 (PSC-17P) between November 2017 and June 2022. Changes in the prevalence of psychosocial risk (global, internalizing, externalizing, and attention scales) from before to during the pandemic were compared by age group, sex, and season.

In a sample of 459,767 health supervision visits, the prevalence of PSC-17P global, internalizing, and attention risk worsened significantly from before to during the pandemic, especially among female adolescents (ages 12.0-17.9). For a pediatrician seeing a hypothetical sample of 1000 adolescent girls, the expected number at risk would have increased from 103 to 131 on the global scale (26.6% increase), from 189 to 231 on the internalizing subscale (22.0% increase), and from 60 to 82 on the attention subscale (35.7% increase). Seasonality had a large effect, with significantly lower PSC-17P risk in the summer every year.

Data from a large, national sample of pediatric visits suggested that global, internalizing, and attention concerns increased slightly overall from before to during the COVID-19 pandemic, with different patterns by age group and sex. Adolescent girls showed substantially increased global, internalizing, and attention problems. These increases support the need for further research and additional individual and system-level interventions.
