In a study of the conservation behavior of 103 grocery shoppers in Chelsea, Michigan, an information and prompting strategy was used to test various rationales for adopting source reduction behavior. The experimental intervention consisted of mailing an educational pamphlet to participants. The experimental design included four treatment groups: a control and three others. These three other treatment groups each received a pamphlet giving environmental, economic, or a combination of environmental and economic rationales to reduce waste at the source. From data collected in pre-and postintervention survey instruments, it was shown that both environmental and economic rationales for practicing source reduction led to significant increases in reported source reduction behavior. Additionally, the type of conservation behavior promoted (e.g., toxics use reduction) and the location in which it is practiced (i.e., at home, at a store) were found to have an impact on the success of the interventions. Participants were more likely to adopt home-based source reduction of nontoxics over either store-based activities or activities involving toxics use reduction.

"However, these variables have numerous limitations in long term (Geller, Winett & Everett, 1982; Katzev & Johnson, 1984). The past studies have found positive relationship between motivation of consumers and environmental behaviour (De Young et al, 1993). It implies that motivation for green consumerism can be influenced by knowledge of relevant issues and previous purchase experiences (Young et al, 2010). "

[Show abstract][Hide abstract] ABSTRACT: One of the activities of psychology is to promote positive change in personal behavior. This article show the usefulness of the theory for behavior change through design effective messages to behavioral change and development programs of psychosocial intervention. The theoretical model focuses in factors of behavioral changing: self-efficacy, skills, disposition and intention (MAHDI). The article describes the theory, shows how they can be applied to the selection environmental behavior, as well as their appropriate application in complementary intervention strategies that includes needs analysis, development and piloting program, applicability, social marketing and evaluation. Finally, how the theory can contribute to design youth intervention programs is discussed.
