Promoting Source Reduction Behavior: The Role of Motivational Information
ABSTRACT 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.

ABSTRACT: The majority of environmental education takes place in informal settings, of which so-called free-choice learning is typical. What is understood by this is a kind of learning which is self-determined and driven by the needs and interests of the learner. The voluntariness of participation in interventions and the fact that they take place in turbulent action settings lead to formidable challenges for impact evaluation, particularly because often no randomized control trials (RCTs) or before-and-after measurements can be carried out. In this article, the evaluation of five different interventions from a large-scale program on consumer climate education provides the empirical background for illustrating the problems confronting quasi-experimental impact analyses in a free-choice context and presenting a possible solution based on propensity score matching (PSM). In a quasi-experimental control-group design, intervention participants and nonparticipants filled out questionnaires featuring the same behavioral intentions. The challenges due to selection processes were met with radius matching on the basis of sociodemographic characteristics as covariates. Sensitivity analyses on the basis of Rosenbaum Bounds and the Hodges-Lehmann point estimator were used for assessing the robustness of treatment effects against unobserved confounding variables. The analyses show that all the interventions under study positively influenced intentions to seek further advice or information on the topics covered. Furthermore, for all the interventions, significant positive effects on the intentions relating directly to climate-friendly behavior could be identified. In this context, PSM and sensitivity analyses proved to be effective methods. However, there were several limitations due to conceptual and methodological issues, and these are discussed below.Evaluation Review 12/2011; 35(6):673-722. · 1.20 Impact Factor

ABSTRACT: In this article the authors study existing waste-disposal intentions and behavior-influencing factors at the household level in Santiago de Cuba. The authors analyze the perceived reputation of the behavior, two different attitude components (sentiment and cost-value ratio), and perceived difficulties. Our focus is to compare three types of waste-disposal behaviors and derive specific interventions. The behaviors most suitable to Cuba are recycling, composting, and reuse. Analysis with structural equation modeling (SEM) reveals relevant differences in factor influence for attitude components and perceived reputation. Recycling and composting are most strongly influenced by affective aspects of attitude, whereas the general attitude toward reuse seems to have a more rational basis. The influence of perceived reputation on recycling is strong, that on composting is moderate, and no influence at all is found for reuse. The authors combine the SEM results with those of the qualitative data analysis of problems and incentives assessed from the participants and suggest behavior-specific interventions.Environment and Behavior 01/2008; 40(4). · 1.27 Impact Factor
