Drawing on the norm activation theory, this research developed a theoretical framework and tested it using structural equation modelling and mediation analysis. This research focuses on the unique context of Jordan, a region grappling with severe water scarcity. Data were collected using an online survey with 222 completed questionnaires retained for data analysis.
The results indicate that WC does not have a significant direct effect on purchase intentions of sustainable apparel (PISA). This finding challenges the assumption that conscientiousness towards water scarcity would drive prosocial behaviours such as purchasing sustainable apparel. However, the findings reveal a full mediation effect of perceived environmental apparel knowledge (PEAK) and perceived environmental concern (PEC) on the relationship between WC and PISA. Such a finding raises awareness of the need to develop consumers' PEAK and PEC by educating them on the importance of WC and the effect of the apparel industry on water preservation. A significant relationship exists between PISA and purchase behaviour of sustainable apparel (PBSA), affirming the role of intentions in driving sustainable purchase behaviours of consumers.
This study provides novel insights into the role of WC in facilitating PISA and PBSA by testing a theoretical model that incorporates various environmental factors. Likewise, it extends the geographical scope of sustainability research and underscores the importance of considering diverse environmental conditions when studying consumer behaviour. The findings provide insights for marketers and policymakers in water-scarce regions, enabling them to develop strategies to promote sustainable apparel consumption.
