The Role of Individual Differences and External Variables in a Test of the Sufficiency of Fishbein's Model to Explain Behavioral Intentions to Conserve Water

The sufficiency of fishbein's attitude model was tested with respect to behavioral intentions to conserve water. Regression analysis showed subjective norms (SN) to be the variable most highly correlated with intentions. It was also found that, contrary to the model, SN and evaluative attitudes (Aact) did not adequately mediate all the variation in intentions accounted for by the variables included in this analysis. Age was found to be an important external variable in explaining water conservation intentions, The equations of the models which predict SN and Aact were also analvzed. Analysis of regressions for dichotomized groups revealed strong individual differences in regression equations. Age, along with SN and Aact, was found to be an important variable in accounting for individual differences. The findings are discussed in relation to the sufficiency of Fishbein's model and the role of individual differences in Understanding water conservation intentions.
