The large, well documented literature on adult environmental attitudes and behaviors contrasts with the relatively few investigations conducted with children. The factors and processes influencing youngsters’ environmental attitudes and behavior are barely known. In this study we analyze children’s ecological worldviews and pro-environmental behaviours using a well-validated, scarcely used tool: the set of games designed by Evans et al. (2007). Given that the affective dimension of environmental attitudes also seems relevant when explaining ecological behaviours, a measurement of children’s emotional connection to nature was also included.

108 children from 6 to 12 participated in the study. At the same time, 108 parents filled a questionnaire registering their ecological worldviews and pro-environmental behaviours, as well as the importance they give to their child spending time in nature.

Our results showed that this tool is adequate to register Spanish children's ecological worldviews, pro-environmental behaviours and emotional connection to nature. Children's emotional connection to nature and pro-environmental behaviours were significantly different according to age, but no gender differences were found. Younger children (6 to 9 years old) showed higher emotional connection to nature than older ones (10 to 12 years old), and they also reported carrying out ecological behaviors more frequently. No differences were found regarding children’s ecological worldviews. Furthermore, contrary to previous studies using this tool, a positive and significant relationship was found between children’s ecological worldviews and pro-environmental behaviours. Similarly to previous studies, parents’ ecological worldviews and pro-environmental behaviours were not related to those of their children. However, a positive and significant relation was found between the importance parents give to their children spending time in nature and children’s emotional connection to nature as well as children’s ecological worldviews. Finally, a structural equation model was proposed to explain children’s pro-environmental behaviours through their ecological worldviews, emotional connection to nature, age, and the importance parents give to children spending time in natural settings.
