Objective Psychosocial interventions targeting glycemic health in youth with type 1 diabetes (T1D) have been promising. Nonetheless, disparities in T1D treatment and outcomes are pervasive among racially/ethnically minoritized (REM) youth and a systematic review examining the inclusion of REM youth in psychosocial interventions is lacking. Therefore, the present systematic review examined the literature to determine the inclusion of REM youth with T1D in psychosocial interventions. Methods A systematic literature review was conducted per PRISMA guidelines for psychosocial intervention studies of youth (<19 years) with T1D between 2011 and 2022 using PubMed, PsycINFO, CINAHL, and MedLine. Tables of contents for JPP, CPPP, and Diabetes Care were also reviewed. The date last searched was April 26, 2022. Studies were examined for risk of bias using the QualSyst rating system. Results Twenty-four studies met inclusion criteria with a total of 3,117 participants. Studies utilized various psychological interventions (e.g., CBT, MI, behavioral modalities). Seventeen studies reported participants’ race/ethnicity and eleven studies included >20% REM youth. Conclusions One study examined the impact of interventions on REM youth or whether the intervention reduces existing racial/ethnic disparities. Implications for future research and practice are discussed.
