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%.

Objectives: This report provides an overview of the National Home Health Aide Survey (NHHAS), the first national probability survey of home health aides. NHHAS was designed to provide national estimates of home health aides who provided assistance in activities of daily living (ADLs) and were directly employed by agencies that provide home health and/or hospice care. This report discusses the need for and objectives of the survey, the design process, the survey methods, and data availability. METHODS NHHAS, a multistage probability sample survey, was conducted as a supplement to the 2007 National Home and Hospice Care Survey (NHHCS). Agencies providing home health and/or hospice care were sampled, and then aides employed by these agencies were sampled and interviewed by telephone. Survey topics included recruitment, training, job history, family life, client relations, work-related injuries, and demographics. NHHAS was virtually identical to the 2004 National Nursing Assistant Survey of certified nursing assistants employed in sampled nursing homes with minor changes to account for differences in workplace environment and responsibilities. RESULTS From September 2007 to April 2008, interviews were completed with 3,416 aides. A public-use data file that contains the interview responses, sampling weights, and design variables is available. The NHHAS overall response rate weighted by the inverse of the probability of selection was 41 percent. This rate is the product of the weighted first-stage agency response rate of 57 percent (i.e., weighted response rate of 59 percent for agency participation in NHHCS times the weighted response rate of 97 percent for agencies participating in NHHCS that also participated in NHHAS) and the weighted second-stage aide response rate of 72 percent to NHHAS.

Objectives: This report describes how the continuous National Survey of Family Growth (NSFG) (begun in 2006) was designed, planned, and implemented. The NSFG is a continuous national survey of men and women 15-44 years of age designed to provide national estimates of factors affecting pregnancy and birth rates; men's and women's health; and parenting.

Methods: The survey used in-person, face-to-face interviews conducted by trained female interviewers. One person per household was interviewed from a national area probability sample. The data collection used computer-assisted personal interviewing (CAPI). Separate questionnaires were used for male and female respondents. The last section of the questionnaires used a self-administered technique called audio computer-assisted self-interviewing or ACASI. Each data collection period lasted 12 weeks-10 weeks for "Phase 1," the main data collection protocol, and 2 weeks for "Phase 2," an intensive attempt to locate and interview nonrespondents.

Results: Each year, about 5,000 persons were interviewed in about 33 areas, called primary sampling units (PSUs). Over a 4-year period, 110 PSUs will be used. This report gives an overview of the procedures used in the conduct of the continuous NSFG. A later report will describe response rates and other results of the data collection, but the early fieldwork has gone well.

Objectives-This methods report provides an overview of how medication data were collected and processed in the 2004 National Nursing Home Survey (NNHS) and how analysts may use the medication data. The 2004 survey marked the first time that medication data were collected on sampled nursing home residents in the NNHS. Information about medications, which are an important component of nursing home care, can help policy makers, researchers, and members of the long-term care community better understand which medications are taken by U.S. nursing home residents. Methods-The medication data were collected in the Prescribed Medications (PM) module of the 2004 NNHS. The computer-assisted personal interviewing (CAPI) instrument, which included a drug lookup list, allowed interviewers to enter a maximum of 25 medications taken on the day before the facility interview and a maximum of 25 medications taken regularly but not on the day before the facility interview. This medication information, which is documented in residents' medication administration records, was collected during a face-to-face interview at the nursing home facilities. All data were provided by facility respondents who used residents' administrative and medical records to answer the survey items. The data were entered into the CAPI instrument that was loaded onto each interviewer's computer laptop. Results and conclusions-Data were collected on 13,507 current residents, 98.5 percent of whom took one or more medications. A stand-alone PM Public-use File has been released. This file, which includes the sampling weight and design variables from the resident file, can be linked to the 2004 NNHS Current Resident Public-use File to generate national estimates on medications by various resident characteristics.

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.

Objectives: This report presents detailed information on the National Asthma Survey (NAS), a module of the State and Local Area Integrated Survey program conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics. NAS, sponsored by the CDC's National Center for Environmental Health, was designed to produce national prevalence estimates of adults and children with asthma; to describe the health, socioeconomic, behavioral, and environmental predictors that relate to controlling asthma better; and to characterize the content of care and limitations of persons with asthma. National prevalence estimates were constructed to be consistent with those produced from the CDC's National Health Interview Survey (NHIS), although prevalence estimates for subpopulations may or may not be consistent with NHIS.

Methods: Two separate random-digit-dial telephone studies were fielded: a national study and a four-state study in Alabama, California, Illinois, and Texas. Children aged 0-17 years and adults aged 18 years and over were included in both studies. The screening procedure differed between the studies. Percentages can be generated for the four states combined or for each state separately. A substudy was conducted in the national study to examine the accuracy of proxy reports of asthma.

Results: Data were collected from February 2003 to March 2004. A total of 955 detailed asthma interviews were completed in the national study and 5,741 in the four-state study. A data file has been released for each study that contains asthma, health, and demographic data, as well as sampling weights. The weighted overall response rates were 47.2% for the national sample and 48.5% for the four-state sample.

Objectives: This report provides an introduction and overview of the National Nursing Assistant Survey (NNAS),the first national probability survey of nursing assistants working in nursing homes. The NNAS was designed to provide national estimates and to allow for separate estimates to be calculated for nursing assistants by geographic location of the agency and for workers by tenure at the sampled facility. This report includes a description of relevant research that led to federal interest in sponsoring the NNAS, types of data collected, methodology, linkage between the NNAS and the 2004 National Nursing Home Survey (NNHS), advantages of combining establishment and worker surveys, and potential uses of the data.

Methods: The NNAS was conducted as a supplement to the 2004 National Nursing Home Survey. The design was a stratified, multistage probability survey. Nursing facilities were sampled and then nursing assistants were sampled within the facilities. Telephone interviews were conducted with nursing assistants using Computer-Assisted Telephone Interviews (CATI). The survey instrument consisted of sections on recruitment, training and licensure, job history, family life, management and supervision, client relations, organizational commitment and job satisfaction, workplace environment, work-related injuries, and demographics.

Results and conclusions: A total of 3,017 interviews were completed from September 2004 to February 2005. The overall response rate was 53.4 percent. A public-use data file has been released that contains the interview responses and sampling weights. The file also includes ownership, bed size, and geographic location of the facility where the nursing assistant was sampled. Estimates based on the sampling weights can be used to produce national estimates.

Objectives: This report describes how Cycle 6 of the National Survey of Family Growth (NSFG) was designed, planned, and implemented. The NSFG is a national survey of women and men 15-44 years of age designed to provide national estimates of factors affecting pregnancy and birth rates; men's and women's health; and parenting. Cycle 6, conducted in 2002, was the first time the NSFG included a sample of males.

Methods: The survey used in-person, face-to-face interviews conducted by trained female interviewers. One person per household was interviewed from a national area probability sample in about 120 sample areas, with oversamples of teenagers, African Americans, and Hispanics. The data collection used computer-assisted personal interviewing (CAPI). Separate questionnaires were used for female and male respondents. The last section of the questionnaires used a technique called audio computer-assisted self-interviewing (ACASI). In order to control costs and nonresponse errors, survey managers statistically analyzed results from interviewers' visits to sampled households each day, and used those results to allocate interviewer labor and other resources more efficiently. This management improved response rates and made the sample more representative.

Results: Over 12,500 interviews were completed, about 7,600 with females and about 4,900 with males. The response rate was about 80 percent for females and about 78 percent for males. The survey procedures were adapted during the fieldwork to achieve the desired response rates and to control costs.

Objectives-This report presents the development, plan, and operation of the National Survey of Children's Health(NSCH), a module of the State and Local Area Integrated Telephone Survey, conducted by the Centers for Disease Control and Prevention's(CDC) National Center for Health Statistics. This survey was designed to produce national and State-specific prevalence estimates for a variety of physical, emotional, and behavioral health indicators and measures of children's experiences with the health care system. The survey also includes questions about the family (e.g., parents' health status, stress and coping behaviors, family activities) and about respondents' perceptions of the neighborhoods where their children live. Primary funding for this survey was provided by the Maternal and Child Health Bureau, Health Resources and Services Administration. Additional support was received from the CDC's National Center for Infectious Diseases, using funds provided by the National Vaccine Program Office. Methods-A random-digit-dial sample of households with children under 18 years of age was selected from each of the 50 States and the District of Columbia. One child was randomly selected from all children in each identified household to be the subject of the survey. The respondent was the parent or guardian who knew the most about the child's health and health care. Results-A total of 102,353 interviews were completed from January 2003 to July 2004. The weighted overall response rate was 55.3%. A data file has been released that contains demographic information on the selected child, substantive health and well-being data for the child and his/her family, and sampling weights. Estimates based on the sampling weights generalize to the noninstitutionalized population of children in each State and nationwide.

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 National Center for Health Statistics, Centers for Disease Control and Prevention. 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. This study included two additional modules to provide health care coverage estimates for all children and to collect data on the reasons that low-income uninsured children lack health care coverage. Primary funding for this survey was provided by the Maternal and Child Health Bureau, Health Resources and Services Administration.

Methods: A random-digit-dial sample of households with children under 18 years of age was selected from each of the 50 States and the District of Columbia. Depending on the health care needs of the children in each household, a detailed interview was conducted for one randomly selected child with special needs and a brief health insurance interview was conducted for one randomly selected child without special needs. The respondent was the parent or guardian who knew the most about the child's health and health care.

Results: A total of 196,888 household screening interviews were completed from October 2000 to April 2002. This resulted in 38,866 completed special-needs interviews and 176,296 completed health insurance interviews for children without special needs. The weighted overall response rate for special-needs interviews was 61.0%.
