Two-Dimensional Scalogram Analysis: Analyzing the Scalability of Attitudes toward Abortion.
Dancer, L. Suzanne
The usefulness of L. Guttman's partial order scalogram analysis is investigated in this study of the structure of a set of items that measure attitudes toward legal abortion. These items, drawn from the National Opinion Research Center's "General Social Survey," have been the focus of considerable applied research investigating predictors of attitudes toward abortion. The data constitute a probability sample of non-institutionalized adults in the contiguous United States. The abortion item includes seven possible situations for which the respondent is to choose whether or not an abortion should be legal. Since the survey items bear some of the characteristics of a perfect scale, they are also useful in demonstrating applications of theoretical research aimed at extending Guttman's model to include response patterns not defined by the original scalogram model. Prior to describing the experimental methodology, three models developed to incorporate non-scale response patterns into the scalogram model are summarized as a contrasting background for the Guttman approach. For each of the 7 years of data analyzed in the study proper, a two-dimensional POSAC-I (Partial Order Scalogram Analysis with Base Coordinates) space fit the data quite well, indicating that the responses of those surveyed do not support the hypothesis of a single order among attitudes toward reasons for legalized abortions. Using this ordinal factor analysis it was possible to determine the structure of the abortion scale items. One table, one figure, and 26 computer-generated scalograms are provided. (TJH)
