While research regarding the effectiveness of the wraparound process is steadily mounting, little is known about how this service delivery model works and for whom. Using data gathered on 176 youth who participated in the wraparound process, the authors examine client and service factors associated with outcomes. Bivariate logistic regression analyses were conducted to determine the likelihood of treatment success based on select child and service characteristics. Results reveal that youth who exhibited lower levels of impairment at service entry were most successful in transitioning to and preserving a home placement, while those who possessed higher numbers of collateral supports were more likely to attain treatment goals. Findings also underscore the value of a planning process that promotes youth and family involvement in community activities. High adherence to this element of practice was found to predict both goal attainment and youth success in transitioning to a home setting. Implications for the implementation of the wraparound process with youth who are in residential care or at risk of out-of-home placement are discussed. (Contains 3 tables.)
