Social advocacy: a conceptual model to extend post-intervention effectiveness

Commercial marketing literature highlights benefits from brand advocates who recruit and promote in the interest of the commercial entity. However, a similar focus is lacking on how advocacy can extend the effectiveness of social change initiatives. We utilise a case study to demonstrate the benefit of social advocacy and its impact on behaviour change, and thereby propose an advocacy model. To develop this conceptual model, we discuss several key areas; behaviour change and advocacy, advocate identification, and how to influence advocacy within communities and individuals. This research provides a guiding framework for practitioners to develop programs and interventions with advocacy triggers and strategies to enhance the longevity and effectiveness of social change programs through participant-based advocacy. Thus, giving intervention programs in a variety of organisational structures e.g. non-profit, corporate, government etc. a specific model to increase the effectiveness of social programs. Our paper extends behaviour change literature by leveraging social marketing concepts to modify and extend the transtheoretical model.
