Cohort profile: Impact of Maternal and Paternal Mental Health - Assessing Concurrent Depression, Anxiety and Comorbidity in the Canadian Family (IMPACT study).

The IMPACT study will examine the influence of parental mental illness in the first 2 years of a child's life with a focus on understanding the mechanisms by which single (maternal or paternal) versus dual (maternal and paternal) parental depression, anxiety and comorbidity symptoms affect family and infant outcomes. Future analyses planned to address the research objectives of IMPACT will consider the longitudinal design and dyadic interparental relationship.
