title: Children's use of mental health services in different Medicaid insurance plans.
abstract: This study examined the effect of different Medicaid insurance plans on children's mental health service use through survey, claims, and encounter data collected between February 1998 and February 1999. Participants were assigned to 1 of 3 insurance plans: fee-for-service, a Health Maintenance Organization and a prepaid carve-out. Logistic and stratified logistic regression were used to examine the effect of plan on service utilization, adjusting for caregiver report of need for services and psychosocial functioning. There was no difference in service use by plan controlling for demographic characteristics; however, when psychopathology and caregiver report of need for services were included in the model, the odds of using services in the Health Maintenance Organization was half of and the odds in the carve-out 29% less than the odds of using services in fee-for-service. Characteristics of the interaction between need, psychopathology, and insurance plan that may be associated with the reduction in service use are discussed.
