Background: The COVID-19 pandemic has changed family functioning and increased parenting demands, leading to increased risk for poor psychosocial outcomes. Emerging evidence underscores the significant impact the pandemic has had on maternal mental health concerns. In contrast, paternal mental health has yet to be described. The current study describes the prevalence of depression and anxiety in fathers of young children as well as associated risk and protective factors.Methods: As part of the Parenting during the Pandemic study, fathers (N = 70) of children age 0-8 years old self-reported on mental health symptoms and additional concerns, while mothers (N = 236) provided a partner-report of father perinatal depression.Results:. Clinically significant depression (37.1%) and anxiety (22.9%) were prevalent in fathers. Partner reported perinatal depression was prevalent in 61.9% of fathers. Higher financial strain and previous mental health history were associated with increased risk of both depression andanxiety. Maternal report of paternal depression was associated with higher financial strain, greater number of children in the home, and lower maternal-reported marital quality. Limitations: The current study used cross-sectional data from an online cohort. The sample size limits the generalizability of the findings; future research should continue evaluating this important topic with larger samples.Conclusions: Compared to pre-pandemic population comparisons, paternal depression and anxiety are elevated in the context of the COVID-19 pandemic. Intervention recommendations and implications are discussed.
