INTRODUCTION

The National Immunization Survey - Teen (NIS-Teen) is sponsored and 
conducted by the National Center for Immunization and Respiratory Diseases 
(NCIRD). The NIS-Teen is a random-digit-dialing telephone survey 
of households followed by a mailed survey to teens' immunization 
providers to monitor adolescent immunization coverage.

The target population for the NIS-Teen is children between the ages of 
13 and 17 years living in the United States at the time of the 
interview. Data from the NIS-Teen are used to produce timely estimates 
of vaccination coverage rates for all adolescent vaccinations 
recommended by the Advisory Committee on Immunization Practices 
(ACIP).

The 2022 NIS-Teen public-use data file is available in ASCII format. 
A SAS program (in ASCII format) is provided to facilitate reading the
ASCII data file and creating a SAS dataset. The SAS program contains,
for each variable in the ASCII file, the variable name, its starting
position and end position, labels, and formats. An R program (in ASCII
format) is also provided to facilitate reading the ASCII data file and
creating an R dataset. The R program contains, for each variable in
the ASCII file, the variable name, its starting position and end
position, labels, and formats. 

The data file NISTEENPUF22.DAT can be used for processing by 
statistical software packages that accept ASCII-formatted input, 
or it can be transferred to another computer for processing.

For more information about the 2022 NIS-Teen PUF, data users should 
consult the 2022 NIS-Teen PUF Data User's Guide and the 2022 NIS-Teen
PUF Data Documentation, Codebook, and Frequencies. Users of these 
data must review that descriptive and explanatory documentation to 
analyze the data correctly. These documents are available in PDF 
format.

The 2022 NIS-Teen PUF Data User's Guide provides detailed information 
about the design of the 2022 NIS-Teen sample, the questionnaires, the 
weighting and estimation procedures, and other important information 
needed for analyzing these data.  

The 2022 NIS-Teen PUF Data Documentation, Codebook and Frequencies 
contains indexes of the variables (in both data-file-position 
order and alphabetical order), the variable responses, and 
either unweighted frequencies of categorical variables or 
unweighted summary statistics for continuous variables.

The 2022 NIS-Teen files are large. Please use caution and check the 
capacity of your disk drive before downloading them.

Documents in PDF format can be viewed with Adobe Acrobat software.

UNIQUE IDENTIFIERS AND WEIGHTING

The unique teen identification number is SEQNUMT. Because only one
teen is selected for the interview per household, SEQNUMT is also
a unique household identifier.

In 2022, the NIS-Teen PUF contains interviews collected by cell phones only. 
To produce estimates for the U.S. proper, the RDD-phase sampling weight is 
called RDDWT_C (RDDWT_C_TERR if territories are to be included), and the 
provider-phase sampling weight for children with adequate provider data is 
called PROVWT_C (PROVWT_C_TERR if territories are to be included).
