“…Recent research suggests that many individuals living with mental illness and/or substance use difficulties have a variety of ongoing unmet psychosocial needs after leaving homelessness, even when they receive HF as an intervention. These include ongoing poverty (Gaetz et al, 2016 ), low levels of community integration (Raphael-Greenfield & Gutman, 2015 ), high levels of substance use (Somers et al, 2015 ), ongoing symptoms of mental illness (Gaetz et al, 2016 ), low levels of engagement in meaningful activity (C. A. Marshall et al, 2018 , 2020 ), and food insecurity (Parpouchi et al, 2016 ). Systems that allow for poor adherence to the HF model, that are poorly integrated, that do not adequately account for consumer choice (Oudshoorn, Smith-Carrier, et al, 2021 ), or that target the security and maintenance of a tenancy as a primary indicator of program effectiveness, may contribute to these outcomes.…”
