||The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive.
Of particular interest to child care and early education researchers is Part 5 of this dataset, the Sample Child File, which contains data on child health, child care access and utilization, child mental health, and child mental health services.

The Child Health Care Access and Utilization Section (CAU) provides information on access to health care, dental care, and health care provider contact, such as having a usual place for sick and preventative care, change in place of care, reasons for a delay in getting medical care, and the inability to afford medical care, time since last dental visit, and visits and telephone contacts to or from medical doctors and other health care professionals. The Child Mental Health Brief Section (CMB) is a behavioral screening for children ages 4 to 17 years with data on the duration of a child?s problem and the impact that the problem has on the child and his/her family. Child Mental Health Services (CMS) section includes information about a health care provider visit for mental health services, medication prescribed for difficulties with concentration, hyperactivity orimpulsivity, receipt of any non-pharmacologic treatment or help for difficulties with concentration, hyperactivity or impulsivity, and the type of provider for this treatment, mental health private practice, clinic, or center.
