| | | | Summary: | 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. Implementation of a
redesigned NHIS, consisting of a basic module, a periodic module, and
a topical module, began in 1997 (see NATIONAL HEALTH INTERVIEW SURVEY,
1997 [ICPSR 2954]). The 2005 NHIS contains the Household, Family,
Person, Sample Adult and Sample Child files from the basic
module. Each record in the Household-level File (Part 1) contains data
on type of living quarters, number of families in the household
responding and not responding, and the month and year of the interview
for each sampling unit. The Family-level File (Part 2) is made up of
reconstructed variables from the person-level data of the basic module
and includes information on sex, age, race, marital status, Hispanic
origin, education, veteran status, family income, family size, major
activities, health status, activity limits, and employment status,
along with industry and occupation. As part of the basic module, the
Person-level File (Part 3) provides information on all family members
with respect to health status, limitation of daily activities,
cognitive impairment, and health conditions. Also included are data on
years at current residence, region variables, height, weight, bed
days, doctor visits, hospital stays, and health care access and
utilization. A randomly-selected adult in each family was interviewed
for the Sample Adult File (Part 4) regarding respiratory conditions,
use of nasal spray, renal conditions, AIDS, joint symptoms, health
status, limitation of daily activities, and behaviors such as smoking,
alcohol consumption, and physical activity. The Sample Child File
(Part 5) provides information from an adult in the household on
medical conditions of one child in the household, such as respiratory
problems, seizures, allergies, and use of special equipment like
hearing aids, braces, or wheelchairs. Also included are variables
regarding child behavior, the use of mental health services, and
Attention Deficit Hyperactivity Disorder (ADHD) as well as responses
to the SDQ-EX, which is the extended version of the Strengths and
Difficulties questionnaire on child mental health. The 2005 data
contain the Child Mental Health Brief (CMB), Child Mental Health
Services (CMS) and Child Influenza Immunization (CFI) sections. The
Injury/Poison Episode File (Part 6) is an episode-based file that
contains information about the external cause and nature of the injury
or poisoning episode and what the person was doing at the time of the
injury or poisoning episode, in addition to the date and place of
occurrence. The Injury/Poison Episode Verbatim File (Part 7) contains
edited narrative text descriptions of the injury or poisoning,
provided by the respondent. The Sample Adult Cancer File (Part 8) has
been added in 2005 and examines diet and nutrition, physical activity,
tobacco use, cancer screening, genetic testing, and family history.
Imputed income files for 2005 are now available through the NCHS Web
site at www.cdc.gov/nhis. |

| | | Data Collection Notes: | (1) The User Guide contains information regarding the
merging of files and the use of weight variables, along with
information regarding changes to the 2005 NHIS. (2) Beginning in 2005,
the NHIS no longer allows an emancipated minor (someone between the
ages of 14-17 and living on their own without supervision of an adult
family member or legal guardian) to be an eligible respondent or a
sample adult or sample child. An emancipated minor is not eligible to
be the respondent for the Sample Child questionnaire even if they are
the parent of the sample child. (3) Questionnaires have been provided
in both English and Spanish. (4) The Injury/Poison Episode Verbatim
File (Part 7) is available only with SPSS and SAS setup files. (5) To

| | | | Sample: | The NHIS uses a stratified multistage probability design.
The sample for the NHIS is redesigned every decade using population
data from the most recent decennial Census. A redesigned sample was
implemented in 1995. This new design includes a greater number of
primary sampling units (PSUs) (from 198 in 1994 to 358), and a more
complicated nonresponse adjustment based on household screening and
oversampling of Black and Hispanic persons, for more reliable
estimates of these groups. |
|---|
| | | Weight: | These data contain multiple weight variables for each part.
Users should refer to the User Guide for further information regarding
the weights and their derivation. Additionally, users may need to
weight the data prior to analysis. |

| | | Mode of Data Collection: | face-to-face interview |

| | | | Note: | A list of the data formats available for this study can be found in the
summary of holdings. Detailed file-level information (such as record length, case count, and variable count) is listed in the
file manifest. |

| | | Restrictions: | In preparing the data files for this collection, the
National Center for Health Statistics (NCHS) has removed direct
identifiers and characteristics that might lead to identification of
data subjects. As an additional precaution, NCHS requires, under
Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that
data collected by NCHS not be used for any purpose other than
statistical analysis and reporting. NCHS further requires that
analysts not use the data to learn the identity of any persons or
establishments and that the director of NCHS be notified if any
identities are inadvertently discovered. ICPSR member institutions and
other users ordering data from ICPSR are expected to adhere to these
restrictions. |
