        ABBREVIATED INTERVIEW FORM - PRE
        -------------------------------------------------------------------

        VCF0015A and VCF0015B codes other than 0 indicate cases where the
        interview is shortened or lacking specific questions due to
        administrative problems or considerations (e.g. accomodation for mail
        or telephone mode).

        This flagging does not include 'Form' desigN assignments(see VCF0012,
        VCF0012A and VCF0012B).

        1980: The abbreviated Pre interviews were administered as replacements
        for discovered 'fake' interviews.

        1992 NOTE:  In addition to the 'long-form' or full questionnaires
        designed for personal interviewing, short-form questionnaires for
        telephone administration were prepared in both the pre and post waves
        for panel cases of respondents who had since 1990 moved out of range
        possible for personal interviews.  Please see the full 1992 NES
        documentation for a complete description of study administration.
        See also VCF0017 and note that, contrary to the intentions of the
        study design, use of the short-form questionnaire was not limited to
        telephone mode, nor was long-form use confined to personal mode
        interviewing.  [Note also that in several cases the shorter interview
        was administered to 'cross-section' respondents-- 4 cases pre, 4 cases
        post].

        1996 NOTE:  CAPI interviewing (Computer Assisted Personal
        Interviewing) was introduced in 1996, and the Pre 'VQ file' or CAPI
        application was revised several times while in the field.  Beginning
        with the CAPI instrument having revision date 9/25/96 through all
        subsequent versions, some questions (most of the items related to 1996
        candidate Ross Perot) were dropped from Pre interviewing. This
        variable identifies interviews administered without these questions.

        2000: In the Pre, Buchanan traits and affects were dropped beginning
        with the 09/28/00 VQ.

                   sections, which were slightly more complete in the Spanish
                   Pre form]
