Linking self‐determined needs and word of mouth to consumer e‐waste disposal behaviour: A test of basic psychological needs theory

E‐waste is recognized as the fastest growing waste stream in the world. It contains toxic substances such as heavy metals and flame retardants that are hazardous to human and ecological health. Despite these environmental and health hazards, the vast majority of consumers are reluctant to dispose of e‐waste and prefer to store obsolete products at home instead of returning them to manufacturers for recycling. To address this alarming problem, we use the basic psychological needs theory (BPNT) and word of mouth (WOM) to profile consumer behaviour changes and explain self‐reported consumer e‐waste disposal behaviours. Based on longitudinal survey data collected over two rounds from Pakistan, the findings support the role of BPNT. Particularly, the results show that positive WOM messages about e‐waste disposal significantly improve consumers' self‐determined needs that, in turn, fuel consumers' integrated motivation for e‐waste and subsequent e‐waste disposal behaviours. The implications of these findings for practitioners regarding consumer behavioural changes are discussed in‐depth.
