>> 1983 PILOT STUDY INTRODUCTION

 During the summer of 1983, the Center for Political Studies of the
 Institute for Social Research, University of Michigan, conducted a
 small pilot survey for the purpose of developing new instrumentation
 for segments of the American National Election Study, 1984. New items
 were tested on several topics including economic well-being, group
 identification, values, political participation, and candidate affect.
 The Pilot Study was designed by a 1984 Study Planning Committee*
 convened by the NES Board of Overseers and was carried out under the
 overall direction of Warren E. Miller, Principal Investigator, and the
 NES Board. A sample of respondents from the American National Election
 Study, 1982, was selected for the Pilot Study. Telephone interviews
 were taken in July with 314 respondents; 274 of these respondents were
 reinterviewed in August. Each wave of interviewing employed two
 questionnaire forms administered to half-samples. A brief description
 of the sampling, field, and coding procedures follows.

 Members of the 1984 Study Planning Committee are: Donald R. Kinder,
 Chair, University of Michigan; Richard A. Brody, Stanford University;
 Stanley Feldman, University of Kentucky Stanley Kelley, Jr.,
 Princeton University; Ethel Klein, Harvard University; Warren
 E. Miller, Arizona State University; Steven J. Rosenstone, Yale
 University; David O. Sears, University of California, Los Angeles;
 and Raymond E. Wolfinger, University of California, Berkeley.
 
 Sampling
 
 All persons (with telephones) interviewed in the 1982 Election Study
 were eligible to be selected for the Pilot Study. All 1982 respondents
 were stratified initially according to degree of interest in politics
 and then, within categories of political interest, by degree of
 urbanicity. From the ordered list and sampling in a systematic manner,
 20 replicates (mini-samples) were drawn with 32 respondents each;
 odd-numbered replicates were assigned questionnaire Form A and
 even-numbered replicates were assigned Form B. Thirteen replicates
 were used in the production phase of the study.
 
 Field Work
 
 Wave I field work began on July 1 and ended on July 25. Interviews
 averaged 34 minutes in length. Wave II field work was carried out from
 August 1 through August 22, with an average length of interview of 26
 minutes. The results are summarized below:

      had a telephone.

>>  1982 PILOT CODING AND DATA PROCESSING
           
Coding was done by the study staff. The coding of all Wave I and Wave
II interviews was completed by late August. Data processing consisted
of a minimal amount of consistency-checking to validate the structural
and substantive aspects of coding, and wild code checks. The data for
Wave I and Wave II were then merged with 1982 Election Study data for
all Pilot respondents. This merged file will be the only data file
distributed for the 1983 Pilot Study. No further data processing is
planned by the study staff or by the Consortium.
           

Data Characteristics

The 1983 Pilot Study data file consists of 1183 variables for 314
respondents. Each data record is ordered as follows:

        1982 Election Study data subset for
        respondents in the Pilot Study                V820001-V820779

        Pilot Study Wave I data, merged
        Samples A and B                               V832001-V832356

        Pilot Study Wave II data, merged        
        Samples A and B                               V833001-V833227

The data are ordered as the questions appear in the interview
schedules. Wave I respondents who refused the reinterview in Wave II
were padded with "missing data" values for all Wave II variables.
           




>>  1983 PILOT DOCUMENTATION FOR THE DATA MAP
           
Documentation for the 1982 data reproduces the text of the Consortium
computer-readable codebook for the 1982 Election Study. Documentation
for Waves I and II is based on the coders' codebooks. Frequencies are
not included in these codebooks. Each question (variable) has:
 
     a) a unique variable number that serves to locate technical
        information about the variable in the data map.
 
     b) a designation of the question number and, for Pilot Study
        variables, the form in which it appears. To filter on form,
        use V832002 in Wave I and V833002 in Wave II.
           
The data map gives the data record location for each variable in the
study. In the variable name fields, two columns of information are
entered for the Pilot Study data. The first column gives the actual
interview schedule question number. The second column records the form
or forms in which the question appears. Entries labelled DEWY
indicate fields padded with zeros.
           
The table below identifies major blocks of substantive information by
variable number.

 Distribution

 The 1983 Pilot Study data file produced by the NES staff is being
 distributed as a Class IV dataset through a special arrangement with
 the Inter-university Consortium for Political and Social Research. At
 Consortium member institutions, the data may be obtained in the usual
 manner for Class IV datasets through the university's Consortium
 representative.
 

>> 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.
