Examining Spillover of Sustainable Behaviour: an Intervention Study from the Perspective of Maltese Public Officers

Abstract

It has long been acknowledged that the various burgeoning problems inflicting the world are deeply rooted in human behaviour. Governance often entails policy formulation and strategies that initiate behavioural change to alleviate such problems and foster sustainability. However, this often appears as a strenuous endeavour, especially at the macro level. For this reason, implementing the behavioural spillover mechanism is deemed befitting. Few studies have directed their attention towards the relationship of individuals’ sustainable behaviour across different settings, and such a perspective could indicate the way forward required within various future policy frameworks. Hence, the following intervention study attempts to examine behavioural spillover, which entails the transfer of attitudes from one domain to another, in this case, from a work-home perspective. This chapter builds upon such notion through a case study from the Maltese islands, the smallest EU member state, by providing insights from public officers. Such sampling population was selected as these individuals work closely within governmental structures and should act as agents of change in this regard. The methodological framework employs a positivist paradigm, based on a quasi-experimental design through an identical pretest and posttest Likert-scale questionnaire distributed to 14 public officers who undertook an educational module about sustainability at the University of Malta. These tests aimed to examine whether spillover of sustainable behaviour occurs within a spatio-temporal context – across the two different domains and during the entire intervention adopted. Quantitative findings are utilized to address two core research questions, from which various trends have been identified. Results show that positive spillover occurs for those behaviours which involve the least time, cost, and effort. It transpires that respondents are not willing to adopt drastic lifestyle changes. Such findings lay the foundation for the recommendations delineated in the current study, which might be helpful to other practitioners in public policy, management, and sustainable development.
