This manual represents a state-of-the-art summary of approaches in child sexual abuse interventions, emphasizing interdisciplinary cooperation between professionals in successful case management. Although prepared specifically for the use of professionals in Region II of the Massachusetts Department of Social Services and containing a service directory for the region, this handbook contains technical assistance and intervention procedural information which is generally applicable to child sexual abuse wherever it occurs.
