National Longitudinal Surveys

NLSY79 Interviews

Interviews with NLSY respondents were conducted yearly from 1979 through 1994. The original interview schedule, which called for personally-administered interviews, was maintained from 1979 through 1986. In 1987, budget constraints dictated a more limited telephone interview. Personal interviews resumed with the 1988 round.

During the 1993 interviews, the traditional paper and pencil interview (PAPI) instruments used during previous interviews were replaced with computer-assisted interviewing (CAPI) for the eligible sample of NLSY respondents. Experimental CAPI administrations with select respondents had taken place during the 1989 and 1990 interviews with documented improvements in data quality. Table 1 summarizes the interview modes used during the 1989-1993 NLSY surveys.
