National Survey of Adoptive Parents


NSAP is the first large, nationally representative survey of adoptive families across adoption types.  A secondary sample focuses on adopted children with special health care needs. These data provide information on the health and well-being of adopted children in the U.S., as well as information about their family’s well-being and adoption-related experiences, including parents’ reasons for adoption and decisions about adoption type, adoption preparation, openness, post-adoption financial and nonfinancial service utilization, and more.

Mode of Collection: 
Telephone Interview Survey.
Selected Content: 
The NSAP was intended to gather information on the characteristics of adopted children and their families and to gain insights into their adoption-related experiences and post-adoption service utilization and needs. Topics include types of adoption, adoption by relatives, contact with birth families, physical health, social and emotional well-being, and parenting.
Population Covered: 
Adopted children in the U.S. ages 0-17, excluding step-parent adoptions.

Children identified as adopted through the National Survey of Children's Health (NSCH) and who did not live with a biological parent and who lived in households where English was spoken, were eligible for the NSAP follow-up interview. The NSAP interview was a call-back scheduled at the end of the NSCH telephone interview. Sampled children included those adopted from other countries, from the U.S. foster care system, and from private domestic sources. Respondents were either the adoptive mother or the adoptive father.

Response Rates and Sample Size: 

A total of 2,089 NSAP interviews were completed from April 2007 to July 2008. The interview completion rate (i.e., cooperation rate) for eligible respondents was 74.4%. The overall response rate, taking into account nonresponse to NSCH, was 34.6%.
