Relieving the global waste problem requires understandings about factors that motivate individuals to take part in waste management behaviours. Building on the Theory of Planned Behaviour (TPB), this study examines the effects of a set of antecedent factors on intentions to engage in waste management behaviours, i.e., reduce-reuse-recycle (3R). The study analysed a cross-sectional online survey responses targeting the Hong Kong (N = 402) and the South Korea (N = 407) general population. Consistent with the literature, results showed that individual intentions to take part in 3R behaviours were predicted by attitudes and perceived behavioural control towards the waste management behaviours, whereas the effects of subjective norms and moral norms on behavioural intentions varied across different contexts. Notably, this study unveiled the potential of social dominance orientation (SDO) to strengthen the TPB framework. Results showed that it exerted a strong influence on existing TPB predictors. Meanwhile, group identification also had a significant association with SDO. Findings provide new evidence and understanding about how individual behaviours could be unconsciously determined by one’s own group identity and social relationships. In addition to previous attempts to incorporate the identity perspective to strengthen the TPB framework, this study illuminates a research direction about the under-explored dynamics between SDO and other known TPB-related variables.
전 세계 폐기물 문제를 완화하려면 개인이 폐기물 관리 행동에 참여하도록 동기를 부여하는 요인에 대한 이해가 필요하다. 본 연구는 계획행동이론(TPB)을 기반으로, 폐기물 관리 행동, 즉 줄이기, 재사용, 재활용 실천 의향에 미치는 요소의 영향을 조사했다. 홍콩(N = 402)과 한국(N = 407) 일반 인구를 대상으로 온라인 설문 조사를 했다. 기존 TPB변수뿐만 아니라 집단 동일시와 사회지배 지향성도 영향을 미친다는 결과 통해 알려졌다
