The moderating role of behavioral difficulty in the attitude-behavior relationship remains a controversial topic in social psychology. Previous research has been unclear in establishing the direction of this moderation, and 3 theoretical models have been proposed: positive and linear; negative and monotonic; and quadratic. The current paper reports analyses of survey data from 5 different studies that afford measures of environmental attitude, behavior, and behavioral difficulty. Across these studies, we found a substantial and unmoderated average attitude-behavior relationship (r = .54). The data also show that the attitude-behavior relationship is weaker for extremely easy and extremely difficult behaviors. Additional analyses suggest, however, that these reductions in the attitude-behavior relationship are probably because of methodological reasons.
