This study assessed service integration promoted by home visitors and community coalitions in Baltimore's Comprehensive Family Support Strategy. The study first assessed home visitors' coordination of services for their clients. Two yearly home visitors surveys (n = 32) assessed changes in their perceptions of 11 community resources' availability, service quality, and referrals made to those resources. There were statistically significant increases in the percentage of home visitors who (a) reported availability of seven resources, (b) gave high service quality ratings for six resources, and (c) referred clients to all 11 resources. The study also assessed six community coalitions' actions to promote service integration during 1 year through observation of coalition meetings. Coalitions discussing more service integration exhibited greater increases in home visitors' perceptions of high service quality and referrals. Home visiting practitioners should consider including coalitions as part of their program models in order to better link clients to appropriate community resources.
