STUDY CONTENT HIGHLIGHTS:
All cases and data from the component studies are present; the ANES 1982 Method Comparison Study is currently not available except in this derivative file. For variables from the 1980 Time Series study, variable naming does not match the variable names used for the 1980 Time Series study release. In the codebook documentation, "T" and "P" are flags used to identify when individual variables represent either the telephone or in-person (Time Series) study.
STUDY DESIGN HIGHLIGHTS:
For the telephone study, different methods were used to identify Congressional districts depending upon whether the case was assigned to the Ann Arbor or Berkeley facility. For questions concerning Congressional candidates or districts, users are cautioned about comparing face-to-face (Time Series) data with data produced by the telephone facilities. Only one CATI facility used a method for district identification which could be compared to the Time Series method of district identification; full documentation is present in the codebook. Another difference between the CATI facilities is found in the administration of a subset of questions which were asked using either branching or 7-point scale format depending upon case assignment to the Ann Arbor or Berkeley sample.
The total sample for each study was drawn to constitute a representative national cross-section, using traditional area probability sampling for the 1982 Time Series study and using Random Digit Dialing (RDD) for the 1982 Method Comparison study. Administration of the Time Series post-election interview began immediately after the November 2 elections, and continued until January 31, 1983; the average interview length was 72 minutes, and an eligible sample of 1,960 persons (cases of unknown eligibility counted as eligible) yielded 1,418 completions. 1982 Method Comparison Study telephone interviews were conducted November 3, 1982 - February 3, 1983 with average interview length unknown; 497 full or partial interviews were completed at the Ann Arbor facility and 501 at the Berkeley facility, for a total of 998 full or partial telephone interviews. The number of eligible persons in the total telephone sample (or in the samples for either CATI location) is unknown.
