Abstract
We examined the longitudinal course of, and pre- and during-pandemic risk factors for, self-injury and domestic physical violence perpetration in young adults during the COVID-19 pandemic. Data came from a Swiss longitudinal study (N = 786, age ˜22 in 2020), with one prepandemic (2018) and four during-pandemic assessments (2020). The prevalence of self-injury did not change between April (during the first Swiss national lockdown) and September 2020 (postlockdown). Domestic violence perpetration increased temporarily in males. Prepandemic self-injury was a major risk factor for during-pandemic self-injury. Specific living arrangements, pandemic-related stressor accumulation, and a lack of adaptive coping strategies were associated with during-pandemic self-injury and domestic violence. Stressor accumulation had indirect effects on self-injury and domestic violence through negative emotions.
