A Cross‐National Study of Nuclear Attitudes, Normative Support, and Activist Behavior: Additive and Interactive Effects1

Abstract

We tested the cross‐national similarity of additive and interactive variants of the Contingent Consistency Hypothesis in regard to antinuclear activist behavior. We predicted that attitudinally consistent behavior is influenced (a) more by specific than general attitudes, (b) by facilitation between normative support and personal attitudes in an interactive manner, and (c) by a fundamental or basic social‐psychological process that can be demonstrated in people from different countries and cultures. These three hypotheses were tested for general (pacifist) attitudes, specific (antinuclear) attitudes, normative support, and antinuclear political activism in samples of college students from the U. S., England, and Sweden. In each sample, specific attitudes were strong, unique predictors of activist behavior (more so than general attitudes), while normative support had no additive influence on this behavior beyond that explained by attitudes for U. S. and British students. Interaction effects were found for both pacifist and nuclear attitudes in conjunction with normative support among the U. S. students, but only for pacifist attitudes in the British sample and only with antinuclear attitudes in the Swedish sample. In contrast with other studies where interaction effects were hypothesized for behaviors that were deviant or typically initiated by others, the present interactions were obtained for lawful behaviors that are often begun and/ or performed alone. With some notable variations, these results were confirmed in each sample, partially validating the cross‐national generality of the interactive attitude‐behavior model for activist behavior.
