National Evaluation of Welfare-to-Work Strategies: 2-Year Child Outcomes Study Survey File

09/10/2001

The Two-Year Child Outcomes Study (COS) Public Use data file and documentation
include:

NOTE:  All files are in ASCII


  \C2PCOVER.TXT describes the contents of the COS files and documentation and
provides important information about calculating impacts with the data set.


  \C2README.TXT (this file) provides a list and brief description of the files
included on this CD.



\NEWWS\PUBLIC\2YEAR\COS\DATA\N2PC1730.TXT

This is the ASCII data file with responses to sections of the survey
administered to COS respondents (N=3,018). The file includes both the original
survey items from the COS modules of the Two-Year Client Survey and created
variables for Child Outcomes Study: covariates used in impact calculations,
subgroups, child outcomes, targeted intervening outcomes, and non-targeted
intervening outcomes. Each sample member has 14 records of data.

The file is sorted by each sample member's randomly generated IDNUMBER and
by record number.


IMPORTANT !!!:

1) Survey responses must be weighted to make the findings generalizable to the
Full Impact sample.  The variable that weights the responses is called FIELDWGT
and is included in the Two-Year Client Survey public use data file (CD #2). See
C2PCOVER.TXT and N2PS_IMP.TXT (on CD #2) for details.

2) Respondents' additional background characteristics and administrative records
data are stored on the Full Impact Sample public use data file (CD #1).

3) Most outcomes for COS respondents and a few additional outcomes for focal
children are stored on the 2-Year Client Survey public use data file (CD #2).
These data should be merged (by IDNUMBER) with outcomes from the COS file for
the most accurate and complete analysis of program effects.

4) Scores on literacy tests administered during the 2-year COS interview are
stored on the Two-Year Literacy and Math Test Scores public use file (CD #4).
COS respondents did not take the math test.

\NEWWS\PUBLIC\2YEAR\COS\CODEBOOK\N2PC_CBK.TXT

This file contains the data codebook, a comprehensive description of
N2PC1730.TXT. For each variable on the data file the codebook
provides the following information:  The name of the variable and
its starting and ending columns on the ASCII file, the variable's SAS
informat (5.0 is the default), the variable label,  a brief
description of the variable and any issues with the variable.
(Note: The data are stored in ASCII, so informats can be changed to
conform to any statistical or econometric software package.) The codebook
also displays the N, NMISS, MEAN, Standard Deviation, Minimum, and
Maximum for each variable.  For variables with 51 values or less,  a
frequency distribution is listed.  The frequencies show the value
labels. These may be copied and, if necessary, modified to be read into
SAS or any other statistical or econometric software package.



\NEWWS\PUBLIC\2YEAR\COS\LAYOUT\N2PCIPUT.TXT

This file contains the body of a SAS input statement (variable name,
starting column, length, informat)  which will read N2PC1730.TXT.
To run this input statement in SAS you must add the word INPUT to the
top line and a semicolon to the bottom line.  This statement can be
modified to input the data into any statistical or econometric software
package.


\NEWWS\PUBLIC\2YEAR\COS\MEANS\N2PCMEAN.TXT

SAS PROC MEANS output contains the following information for all
variables:

        N, NMISS, MEAN, STD DEV, MINIMUM, MAXIMUM


\NEWWS\PUBLIC\2YEAR\COS\LABEL\N2PCLABL.TXT

SAS variable label statements for each variable of the data file.
Labels can be modified to conform to syntax rules of any statistical or
econometric software package.



\NEWWS\PUBLIC\2YEAR\COS\MEMOS


  \N2PCVARS.TXT provides additional background information on survey responses
and outcome measures created from these data.

  \N2PCCOVA.TXT contains SAS code that shows how covariate and subgroup
   measures were created.



\NEWWS\PUBLIC\2YEAR\COS\OUTPUT

 \BRAKHLTH.LST SAS output showing control group means on the Bracken raw score
and the maternal reports of the child being in very good or excellent health
within each site and comparing across sites. Shows data in Table 5.1 of the COS
2-year impact report.


  \CSEMPLOY.LST SAS output showing control group means on employment variables
within each site and comparing across sites. Shows data in Table 8.1 of the COS
2-year impact report.


  \GLMBRAKN.LST SAS output showing impacts on the Bracken raw score.   Shows
data in Table 6.2 of the COS 2-year impact report.


  \LOGHLTH.LST SAS output showing impacts on the whether the focal child was in
very good or excellent health.  Shows data in Table 6.2 of the COS 2-year
impact report.


  \EDURSKSG.LST SAS output showing impacts on the mean Bracken score for the
subgroups based on education/literacy risks. Shows data in the COS 2-year
impact report's Appendix Table 7.1.


  \CUMRSKSG.LST SAS output showing impacts on the measure of whether the focal
child was in very good or excellent health, for the subgroups based on the
total number of composite risks.  Shows data in the COS 2-year impact report's
Appendix Table 7.11.


\NEWWS\PUBLIC\2YEAR\COS\TABLES

\SAMTBL1.TXT displays sample sizes for full impact sample, Two-Year Client
Survey respondents, 2-year Child Outcomes Study survey respondents, Private
Opinion Survey respondents, and sample members who completed literacy and math
tests at baseline.  The table also shows random assignment dates.
