Motivational Network Intervention to Reduce Substance Use and Increase Supportive Connections for Emerging Adults in a Supportive Housing Program.

Background: For transition-aged youth experiencing homelessness (TAYEH) moving to transitional housing, a motivational network intervention (MNI) may help modify high-risk networks, thereby reducing substance use and strengthening prosocial connections.

Methods: Thirty-six TAYEH received a four-session MNI integrated into usual housing case management or usual case management. Intervention acceptability, feasibility, and motivational interviewing fidelity were evaluated.

Results: Nearly all participants would recommend the MNI to others, formed goals, and believed the program improved their lives. Case managers delivered the program with fidelity. However, sample size and number of sessions delivered fell short of targets due to COVID-19 disruptions and other factors and limited our ability to examine preliminary effects on substance use and network outcomes in a fully powered trial.

Conclusion: Case managers can successfully deliver the MNI, but its use may not be feasible unless adaptations are made to accommodate the instability this population faces when they enter housing.
