Adolescents' motivation toward the environment: Age-related trends and correlates.

From a self-determination perspective, we attempted to replicate previous findings suggesting that higher autonomous environmental motivation (i.e., acting out of choice and pleasure) is associated with the frequency of environmental behaviours such as recycling, paper reuse, and energy conservation. We also compared students' level of autonomous environmental motivation with their level of autonomous academic motivation. We then examined age effects on autonomous environmental motivation and compared them to age effects on autonomous academic motivation. A total of 200 high school students grouped into 5 age cohorts filled out a questionnaire. Results showed that (1) adolescents' autonomous environmental motivation was associated with more frequent environmental behaviours, (2) autonomous motivation was higher in the environmental than the school domain, and (3) autonomous environmental motivation was higher in older than younger students, whereas autonomous motivation toward school was equivalent across age groups.
