Young Adults' Mental Health and Unmet Service Needs in the Context of the COVID-19 Pandemic Across Canada and France.

While young adults experienced mental health challenges during the COVID-19 pandemic, little is known about how their mental health needs were subsequently met through access to mental health services (MHS). From October to December 2020, we conducted an online survey of young adults (18-29 years) living in Canada and France to investigate factors associated with unmet MHS needs. Of the 3222 participants expressing a need to access MHS (50.7% of the total sample), 58.2% in Canada and 74.8% in France reported unmet MHS needs. In both countries, those who identified as men and those who lost income due to COVID-19, were more likely to report unmet MHS needs. In Canada, participants from Quebec, those living in rural areas, and those who experienced ethno-racial discrimination had higher odds of reporting such unmet needs. Urgent investments are needed to improve access to MHS for young adults during and after the COVID-19 pandemic.
