Do Peers, Neighborhood Disorder, Religiosity, Spirituality, and Family Support Influence Polysubstance Use Among Older Youth Transitioning from Foster Care?

Purpose: Few studies have explored polysubstance use among youths aging out of foster care, despite higher rates of substance misuse for youths exiting foster care than those in the general population. Polysubstance use has been linked to substance use disorders, health problems, cognitive impairment, suicide, and overdose.

Method: This study investigates understudied risk and protective factors associated with polysubstance use with data from 384 youth who turned 17 years old between December 1, 2001, and June 30, 2003, and were transitioning out of foster care from the Missouri Children's Division. We conducted bivariate analyses with chi-square tests for categorical variables and Analysis of Variance with continuous independent variables. Then we conducted a multinomial logistic regression to explore differences between individuals who used 1 or no substances, individuals who used only alcohol and marijuana, and individuals who used 2 or more substances.

Results: Bivariate analyses found that being white, having deviant peers, and living in a more disordered neighborhood were risk factors for polysubstance use. Multinomial logistic regression results found that being white (RR = 6.89, p < .001), having deviant peers (RR = 1.15, p < .001), and living in a more disordered neighborhood (RR = 1.13, p < .05), increased the risk engaging in polysubstance use.

Discussion: Similar to findings in other studies, we found that deviant peers and neighborhood disorder increase the risk of polysubstance use, but family support, church attendance, and spirituality were not protective against polysubstance use.

Conclusion: Interventions should work to reduce deviant peer relationships among foster youth.
