The role of personal involvement, credibility and efficacy of conduct in reported water conservation behaviour

We analyse the influence of personal involvement, credibility given to water scarcity, and the perceived efficacy of conducts on reported water conservation behaviour (RWCB). Similarly, we analyse differences in this reported behaviour using age, sex and habitat. Using a Spain-wide survey (n = 637) conducted in 20 cities experiencing or not water scarcity. Data collection was undertaken using Web and paper surveys. Instruments were validated, and measure invariance was tested using habitats. R2 is small but the contribution of each variable resulted statistically significant, except for the credibility given to water scarcity. Discriminant analysis groups 99.4% into two clusters with different RWCB. Credibility of facts and risks do not result significant in the creation of these groups. As involvement is significant and credibility of information is not, we conclude that informative aspects do not help to generate greater RWCB. We suggest possible explanations of the findings, and point out implications for further research
