WHY DO YOU ADOPT ECOLOGICAL BEHAVIORS - VALIDATION OF THE FRENCH VERSION OF THE MOTIVATION TOWARDS THE ENVIRONMENT SCALE

This article presents the French-Canadian validation of the Motivation Towards the Environment Scale (MTES), along with information regardin g its psychometric properties. The ''Echelle de Motivation vis-a-vis l es Comportements Ecologiques'' (EMCE) is based on Self-determination T heory. It consists of 6 subscales measuring intrinsic motivation (IM), four forms of extrinsic motivation (EM. by external, introjected, ide ntified, and integrated regulation), and amotivation. In Study 1, resu lts of a confirmatory factor analysis (using LISREL VII) supported the factorial structure of the scale. In addition, the construct validity of the EMCE was supported by a series of correlational analyses among the 6 subscales, as well as between these subscales and several varia bles relevant to the environment: Finally, results of Study 2 reveal t hat the EMCE subscales displayed satisfactory internal consistency, as well as high temporal stability. The results compared quite favourabl y to those of the English-Canadian version. Directions concerning the future use of the EMCE in environmental research are proposed.
