Design and Operation of the National Survey of Children's Health, 2011-2012.

Objectives This report presents the development, plan, and operation of the 2011-2012 National Survey of Children's Health, a module of the State and Local Area Integrated Telephone Survey, conducted by the National Center for Health Statistics. Funding was provided by the Maternal and Child Health Bureau, Health Resources and Services Administration. The survey was designed to produce national and state prevalence estimates of the physical and emotional health of children aged 0-17 years, as well as factors that may relate to child well-being including medical homes, family interactions, parental health, school and after-school experiences, and neighborhood characteristics.

Design and operation of the National Survey of Children with Special Health Care Needs, 2009-2010.

OBJECTIVES: This report presents the development, plan, and operation of the 2009-2010 National Survey of Children with Special Health Care Needs, a module of the State and Local Area Integrated Telephone Survey. The survey is conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. This survey was designed to produce national and state-specific prevalence estimates of children with special health care needs (CSHCN), to describe the types of services that they need and use, and to assess aspects of the system of care for CSHCN. METHODS: A random-digit-dial sample of households with children under age 18 years was constructed for each of the 50 states and the District of Columbia. The sampling frame consisted of landline phone numbers and cellular(cell) phone numbers of households that reported a cell-phone-only or cell-phone-mainly status. Children in identified households were screened for special health care needs. If CSHCN were identified in the household, a detailed interview was conducted for one randomly selected child with special health care needs. Respondents were parents or guardians who knew about the children's health and health care. RESULTS: A total of 196,159 household screening interviews were completed from July 2009 through March 2011, resulting in 40,242 completed special-needs interviews, including 2,991 from cell-phone interviews. The weighted overall response rate was 43.7% for the landline sample, 15.2% for the cell-phone sample, and 25.5% overall.

Nonresponse in the National Survey of Children's Health, 2007.

OBJECTIVES: For random-digit-dial telephone surveys, the increasing difficulty in contacting eligible households and obtaining their cooperation raises concerns about the potential for nonresponse bias. This report presents an analysis of nonresponse bias in the 2007 National Survey of Children's Health, a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. METHODS: An attempt was made to measure bias in six key survey estimates using four different approaches: comparison of response rates for subgroups, use of sampling frame data, study of variation within the existing survey, and comparison of survey estimates with similar estimates from another source. RESULTS: Even when nonresponse-adjusted survey weights were used, the interviewed population was more likely to live in areas associated with higher levels of home ownership, lower home values, and greater proportions of non-Hispanic white persons when compared with the nonresponding population. Bias was found (although none greater than 3%) in national estimates of the proportion of children in excellent or very good health, those with consistent health insurance coverage, and those with a medical home. However, the level and direction of the bias depended on the approach used to measure it. There was no evidence of significant bias in the proportion of children with preventive medical care visits, those with families who ate daily meals together, or those living in safe neighborhoods.

Design and operation of the Survey of Adult Transition and Health, 2007.

OBJECTIVES: This report documents the survey design and operating procedures for the 2007 Survey of Adult Transition and Health (SATH). Sponsored by the Maternal and Child Health Bureau of the Health Resources and Services Administration, SATH was conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics as a module of the State and Local Area Integrated Telephone Survey program. A follow-back survey design was used to attempt to locate and contact 10,933 eligible cases originally identified in the 2001 National Survey of Children with Special Health Care Needs (NS-CSHCN). These data examine the transition experience of adolescents as they switched from pediatric health care providers to those that treat adults only. Eligible persons were aged 14-17 years as of 2001, had at least one special health care need, and lived in English-speaking households. In 2007, these cases involved young adults aged 19-23. State estimates cannot be obtained from SATH. METHODS: Telephone numbers sampled in 2001 were dialed to locate the 2001 NS-CSHCN respondent. This person was asked for current contact information for the eligible SATH young adult to be contacted directly. Data were collected from June 12 through August 26, 2007. RESULTS: Although we were unable to contact 7409 (68%) of the 2001 parent/guardian respondents, almost all of the young adults we were able to contact participated (98%). The SATH public-use microdata file contains interview data collected in 2007 from 1,865 young adults, along with variables from the 2001 NS-CSHCN public-use file. The unweighted interview completion rate was 17.5%.

Design and operation of the National Survey of Adoptive Parents, 2007.

OBJECTIVE: This report presents the development, plan, and operation of the National Survey of Adoptive Parents (NSAP), a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. NSAP was designed to produce national estimates of the characteristics, health, and well-being of adopted children and their families, the preadoption experiences of the adoptive parents, and their access to and utilization of postadoption supports and services. Funding for the survey was provided by the Office of the Assistant Secretary for Planning and Evaluation and the Administration for Children and Families, both of the Department of Health and Human Services. METHODS: The National Survey of Children's Health, 2007 (NSCH) was a random-digit-dial telephone survey of households with children under age 18 years. In households with more than one child, one child was randomly selected to be the subject of the interview. Children identified as adopted, 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. RESULTS: 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%.

Design and operation of the National Survey of Adoptive Parents of Children With Special Health Care Needs, 2008.

OBJECTIVE: This report presents the development, plan, and operation of the National Survey of Adoptive Parents of Children with Special Health Care Needs (NSAP-SN), a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The survey was designed to produce national estimates of the characteristics, health, and well-being of adopted children with special health care needs (CSHCN) and their families, the preadoption experiences of the adoptive parents, and their access to and utilization of postadoption services. Funding was provided by the Office of the Assistant Secretary for Planning and Evaluation and the Administration for Children and Families, both of the U.S. Department of Health and Human Services. METHODS: The National Survey of Children with Special Health Care Needs 2005-2006 (NS-CSHCN), a random-digit-dial telephone survey of households with children, included questions that identified whether the sampled child was adopted. Adopted CSHCN under age 18 in 2008 who lived in households where English was spoken were eligible for the NSAP-SN follow-up interview. The NSAP-SN interview was a follow-back telephone call 1 to 3 years after the original NS-CSHCN interview. Sampled children included CSHCN 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. RESULTS: A total of 1,007 NSAP-SN interviews were completed from February 2008 to July 2008. The interview completion rate (i.e., cooperation rate) for eligible respondents was 67.3%. The overall response rate, taking account of nonresponse to NS-CSHCN, was 37.7%.

Design and operation of the National Survey of Children with Special Health Care Needs, 2005-2006.

OBJECTIVES: This report presents the development, plan, and operation of the National Survey of Children with Special Health Care Needs (CSHCN), a module of the State and Local Area Integrated Telephone Survey, conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. This survey was designed to produce national and state-specific prevalence estimates of CSHCN, describe the types of services that they need and use, and assess aspects of the system of care for CSHCN. Funding for this survey was provided by the Matemal and Child Health Bureau, Health Resources and Services Administration. METHODS: A random-digit-dial sample of households with children younger than 18 years of age was constructed for each of the 50 states and the District of Columbia. All children in each identified household were screened for special health care needs. If CSHCN were identified in the household, a detailed interview was conducted for one randomly selected child with special health care needs. Detailed interviews were also conducted for a separate national sample of children, to generate estimates for children without special health care needs, and permit comparisons with CSHCN on all study measures. The respondents were parents or guardians who knew about the children's health and health care. RESULTS: A total of 192,083 household screening interviews were completed from April 2005 to February 2007. This resulted in 40,840 completed special-needs interviews and 6,113 completed interviews for children in the comparison (referent) sample. The weighted overall response rates were 56.1% for special-needs and 50.3% for referent-sample interviews.
