“…National investigations of healthcare experiences among patients with MHSUDs (e.g., patient perceptions of the accessibility of needed services, provider communication skills, and office staff helpfulness/courtesy) have not reported on findings for homeless persons (Burnett-Zeigler, Zivin, Ilgen, Islam, & Bohnert, 2011; Jones et al, 2016; Kilbourne et al, 2006). Studies focused on homeless persons’ experiences have been restricted to a small number of clinics (Chrystal et al, 2015; Zerger et al, 2014), have lacked a non-homeless comparison group (Kertesz et al, 2014), had small samples (Steward et al, 2016), or did not assess patient experiences with care in domains relevant to MHSUD care (e.g., comprehensiveness, care coordination, medication decision-making) (Lebrun-Harris et al, 2013). This is a notable gap in the literature considering that homeless persons disproportionately suffer from MHSUDs and patient experiences with care in general outpatient settings affect MHSUD service use and clinical outcomes (Bauer et al, 2014; Kim et al, 2007; True, Rigg, & Butler, 2015).…”
