Study Content Highlights

In addition to content on electoral participation, voting behavior, and public opinion, the 1986 ANES contains questions in other areas such as values and predispositions, and evaluation of parties. Special-interest and topical content includes new items on political knowledge, racial attitudes, racial policy, and the introduction of the battery on moral traditionalism.

Study Design Highlights

The 1986 ANES was conducted using 2 randomly-assigned versions or ‘forms’ of the questionnaire. To reduce overall interview length, approximately 25% of content was assigned to half-samples through the form assignments, with 75% of content identical between forms. Questions specific to form ‘A’ covered material relevant to Presidential evaluation, and questions unique to form ‘B’ were race-related. Among design features of the 1986 ANES was the coding of probes used by interviewers for a subset of specific questions.

Administration of the post-election interview began immediately after the November 4 elections, and continued until February 7, 1987. The average interview length was 74 minutes, and 2,176 completions were yielded from 3,645 eligible in the sample.

For the post-election survey, the minimum rate (AAPOR RR1) is 53.9 percent; the estimated rate (AAPOR RR3) is 57.7 percent; the maximum rate (AAPOR RR5) is 70.8 percent. The re-interview rate is 90.5.
