The synergistic impact of motivations on sustained pro-environmental consumer behaviors: an empirical evidence for single-use plastic products

Abstract

Purpose

This paper employed the self-determination theory (SDT) to examine the synergistic impacts of intrinsic, extrinsic and prosocial motivations in promoting sustained pro-environmental consumption behaviors (PECB). To provide evidence for the study’s theoretical framework, the authors focus on the behavior of reducing single-use plastics.

Design/methodology/approach

A mall-intercept survey for consumption of single-use plastic products in three big cities of Vietnam (Hanoi, Da Nang and Ho Chi Minh city) was conducted to test the theoretical framework. In total, 468 consumers completed the questionnaires. Data were analyzed with SPSS and AMOS.

Findings

Intrinsic and prosocial motivations are found to be significant predictors of sustained PECB. More importantly, beyond the direct effects of intrinsic and prosocial motivations, the authors also found positive interaction effects between intrinsic and extrinsic motivation and between intrinsic and prosocial motivation on encouraging sustained PECB.

Originality/value

This research offers a new insight for encouraging sustained PECB. Different from the extant perspectives which usually deal with initiating PECB, the authors emphasize sustaining the behavior. Moreover, this research examines the interaction effects between intrinsic and extrinsic motivations and between intrinsic and prosocial motivations in sustaining PECB.
