The ecological and societal problems caused by product obsolescence and consumerism in modern economies constitute a ‘wicked human‐made problem’ of significant magnitude. Current (old) ways of thinking cannot address these problems. Accordingly, in this paper, we critically explore the novel idea of integrated personhood and worldviews to theorise research on self‐repairers and their repair behaviours to extend product lifetimes. We conducted a structured and systematic review of published work (n=183) to identify the conceptual content of the field to inform our theorisation. Our findings highlight three key issues. Firstly, constricted theorisation undermines understanding of self‐repairers and their product lifetime extension (and spillover) behaviours. Secondly, the underlying conceptual complexity is typically underestimated. Thirdly, the dominance of voluntarist and deterministic studies impedes new directions in research. From our review, an integrated worldview‐personhood framework emerges that can deepen understanding of avant‐garde self‐repairers’ engagement with product lifetimes.
In this paper, we respond to the call for more holistic and culturally diverse research to advance understanding of (non)sustainable consumption behaviour. Our conceptual model incorporates materialism, environmental concern, social consumption motivation, pro-environmental self-identity and sustainable consumption behaviours. This paper contributes to knowledge by examining the mediating role of pro-environmental self-identity to more fully explain consumers’ (non)sustainable consumption behaviour. An international online panel survey was employed in the UK (n = 1037) and China (n = 1025). Findings show that pro-environmental self-identity partially or fully mediates the relationships between materialism, environmental concern, social consumption motivation and sustainable consumption behaviours. Important cultural differences also emerged, for example, the positive effect of materialism on Chinese consumer’s sustainable consumption, which is contrary to Western evidence. We suggest bolder, culturally informed and more reflexive marketing strategies are needed to significantly advance sustainable consumption, thus effectively helping to redress the crisis facing our planet.
