Childhood mental health disorders are on the rise in the United States. To ensure equitable access to care, it is important to examine the characteristics of children and families who access services. This study compares the demographic characteristics of two samples of families who participated in National Institute of Mental Health-funded studies of a Multiple Family Group model, entitled the 4Rs and 2Ss Multiple Family Group (4Rs and 2Ss) in New York City. One sample is currently receiving services, and the other received services a decade ago. Significant differences in demographic characteristics were found between the two samples pertaining to child race, child nativity, caregiver age, primary caregiver, caregiver marital status, caregiver race, caregiver education, caregiver employment, and family income. Families currently engaging in the public mental health service system are primarily White, and are less disadvantaged than families a decade ago. These differences are examined in light of changing policy and epidemiological trends, and potential unintended consequences are discussed.
