The articles were empirical quantitative, qualitative, or mixed-methods studies published within 2017- 2021 where study participants were clinically diagnosed with schizophrenia and intervention approaches were within the scope of family involvement. Twenty-four articles met the inclusion criteria for review. Evidence supports a professionally engaged relationship between patients, families, and providers with open knowledge exchange, communication, and collaboration.
