Method: Participants included 236 adolescents (130 males; M<inf>age</inf> = 16.74 years in spring 2020; 49.6% diagnosed with attention-deficit hyperactivity disorder; 16.1% diagnosed with an anxiety or depressive disorder) in the United States who completed online questionnaires at four timepoints (spring 2020, summer 2020, fall 2020, spring 2021). Results: Repeated measures ANOVA showed that psychological trauma was highest during stay-at-home orders in spring 2020, and decreased for a majority of adolescents by the summer of 2020. However,~20% of adolescents exhibited moderate-to-clinical levels of psychological trauma at each timepoint. Four groups were identified based on the presence of psychological trauma symptoms: (a) resilient group (normal range across all timepoints; 60.6%); (b) moderate fluctuating group (moderate range at 1 or more timepoints; 18.2%); (c) severe fluctuating group (clinical range at 1 or more timepoints; 14.0%); and (d) chronic psychological trauma group (moderate or clinical range across all timepoints; 7.2%). Females, adolescents with preexisting internalizing disorders, and participants whose families were most impacted by the pandemic were more susceptible to experiencing psychological trauma symptoms. Conclusions: Findings highlight at-risk populations and suggest that the COVID-19 pandemic resulted in psychological trauma symptoms for approximately 20% of adolescents at some point during the first year of the pandemic. There is critical need to provide mental health services to adolescents, such as through school-based services, to reduce the negative long-term psychological impact of the pandemic.Pages 404-41411 page(s)application/pdfenIn CopyrightCOVID-19 pandemicadolescentspsychological trauma symptomsHumansLongitudinal StudiesProspective StudiesAdolescentFemaleMalePandemicsPsychological TraumaCOVID-19Article - Refereedhttps://doi.org/10.1037/tra0001311153Breaux, Rosanna [0000-0001-5500-6950]358620871942-969X
