The 1987 Pilot Study, like its predecessors, provides an opportunity for
social scientists to refine existing NES measures and develop and test new
instrumentation. This Pilot Study carries new measures of foreign policy
attitudes, system support, and morality. A significant portion of
the study is devoted to experiments in question wording and question order
effects.

Study Design 

The Pilot Study can be thought of as a three-wave panel. A subsample of 457
respondents to the 1986 National Election Study were interviewed between May 5
and May 30, 1987; 360 of these people were reinterviewed between June 2 and
July 2, 1987. The ICPSR dataset includes variables from the 1986 NES for the
457 Pilot Study cases. To facilitate the testing of the new items, two forms
were used in each of the two waves. 

Study Administration 

The Survey Research Center at the Institute for Social Research administered
the pilot study by Computer Assisted Telephone Interviewing (CATI).  Responses
to open-ended questions, however, were recorded in pencil in separate
booklets, and later coded by the SRC coding section.  To facilitate your use
of the dataset, we have prepared paper and pencil questionnaires so that the
flow of the questioning can be more easily seen.
                                
Study Processing 

Interviewing on the study ended July 2nd, and coding continued for two
additional weeks. After the various components of the dataset had been merged
together, the study staff scanned the frequencies for each variable. Beyond
these very minimal checks, the NES staff has not done any processing of these
data. If you discover any problems in the data or encounter difficulty using
the data file, please contact me or a member of the project staff so we can
assist you and alert other users to the problem.
                
How to Order the 1987 Pilot Study 

If you are at an institution that is a member of the ICPSR, you should contact
your Consortium representative and order this Class IV dataset in the usual
manner. If you are not affiliated with an ICPSR member institution, you can
also secure the 1987 Pilot Study Data and accompanying documentation from the
ICPSR. Contact for details.

           TO: Santa Traugott, NES Study Staff
           SUBJECT: 1987 NES Pilot Study
           FROM: Steve Heeringa, Sampling Section
           DATE: 13 July l9B7
           
         
           The 1987 NES Pilot Study is a reinterview of a probability sample
of n=633 of the original 1086 Form A respondents to the 1986 NES post-election
survey. (Sample selection was actually restricted to 955 of the 1986 NES Form
A respondents who provided a telephone number for recontact). Using an
experimental approach that followed ideas first brought to the NES staff in
the form of a memo from John Zaller, the Pilot Study sample was
disproportionately allocated across five strata of sample respondents. The
five strata were defined using 1984 NES quintile ranges for a special voter
knowledge and interest index. Based on the 1984 scoring system, an
index value was assigned to each of the 1986 NES Form A respondents. Table 1
below describes the distribution, of the 1986 NES Form A respondents to the
five voter knowledge strata. (Note: Since the strata are defined on the basis
of 1884 quintile ranges, each of the five voter knowledge strata will not
necessarily contain exactly 20% of the l986 sample cases).
           
           Underlying this stratified sampling approach is a reasoning which
says that the Pi1ot Study respondents shou1d bear a characteristic resemb1ance
to the 1986 NES respondents or prospectively to the cross-section of
respondents who will participate in the l988 NES. If an equal probability
sample of 19866 NES respondents is selected for the Pilot Study contact,
nonresponse will distort this characteristic representation whenever the
response (or observation) probability is correlated with the characterist in
of interest. The vote, knowledge index is one such characteristic.
Conventionally, adjustments for nonresponse are introduced through post-survey
weighting. The procedure involves formation of nonresponse adjustment strata
and assignment of case weights which reflect the nonresponse pattern within
the strata.
           
           Drawing heavily on past experience with the NES Pilot Study series,
the current design for the 1987 NES Pilot shifts the nonresponse adjustment
born the post-survey period to the stage at which the sample is designed and
selected. For the l987 Pilot Study, strata of NES respondents defined by the
quintile ranges of the knowledge index for l984 respor,dents were
disproportionately sampled. Sampling rates for the five knowledge strata were
set inversely proportional to the 1985 Pi1ot study response rate experience.
(See Table 1 ) .
           
           In theory, if the 19B7 response rate experience is identica1 to
that for l985, the l987 Pilot Study data base will emerge from the process
with a knowledge index distribution which parallels that of the original 1986
NES data set. No further nonresponse correction may be needed. The sampling
plan does not guarantee the elimination of nonresponse bias from the data
set. The extent to which this sampling strategy succeeds in attenuating Pilot
Study nonresponse bias is a function of the correlation between such biases
and the stratifying variable and the extent to which there is exchangability
in characteritics among respondents and nonrespondents
within the individual sample design strata.
           
RECONSTRUCTING A "STANDARD" SAMPLE
           
           Some analysts of the 1987 NES Pilot Study data may feel
uncomfortable with the sampling plan and its implicit nonresponse adjustment
or they may wish to perform certain analyses in which the sample is
standardized with that of prior Pilot Study datasets. To aid these
researchers, Sampling Section has resampled the 1987 NES Pilot Study sample
control file, effectively reconstructing a data subset (sma11er in case count)
with the equa1 probability (EPSEM) sample design properties and nonresponse
characteristics of past Pilot Studies. After resampling, the EPSEM data subset
of n=515 cases should mimic the response outcome of a 1 in 2.10 sampling of
the original n=1086 Form A respondents to the l986 NES.
           
           The EPSEM subset of cases is flagged in the 1987 NES Pilot Study
data set by a value of '1' for variable 872317.

>> CODEBOOK INFORMATION

The following example from the 1948 NES study provides the standard 
format for codebook variable documentation. 

Note that NES studies which are not part of the Time-Series usually
omit marginals and the descriptive content in lines 2-5 (except for
variable name).

Line 2 - VARIABLE NAME.  Note that in the codebook the variable name
         (usually a 'number') does not include the "V" prefix which is 
         used in the release SAS and SPSS data definition files
         (.sas and .sps files) for all variables including those
         which do not have 'number' names.  For example the variable
         "VERSION" in the codebook is "VVERSION" in the data definition
         files.

Line 2 - "NAME".  This is the variable label used in the SAS and SPSS
         data definition files (.sas and .sps files).  Some codebooks 
         exclude this.

Line 3 - COLUMNS.  Columns in the ASCII data file (.dat file).

Line 4 - CHARACTER OR NUMERIC.  If numeric and the variable is a decimal
         rather than integer variable, the numer of decimal places is 
         also indicated (e.g. "NUMERIC  DEC 4")

Line 5 - Values which are assigned to missing by default in the Study's
         SAS and and SPSS data definition files (.sas and .sps files).

Line 7 - Actual question text for survey variables or a description of 
         non-survey variables (for example, congressional district).
         Survey items usually include the question number (for example
         "B1a.") from the Study questionnaire; beginning in 1996 
         non-survey items also have unique item numbers (for example
         "CSheet.1").

Line 9 - A dashed or dotted line usually separates question text from
         any other documentation which follows.

Line 10- When present, annotation provided by Study staff is presented
         below the question text/description and preceding code values.

Lines 11-16
         Code values are listed with descriptive labels.  Valid codes
         (those not having 'missing' status in line 5) are presented
         first, followed by the values described in line 5.  For
         continuous variables, one line may appear providing the range
         of possible values.  A blank line usually separates the 'valid'
         and 'missing' values.

Lines 11-16
         Marginals are usually provided for discrete variables.  The
         counts may be unweighted or weighted; check the Study codebook
         introductory text to determine weight usage.
