Peer Review Report For: An Integrated Model of Consumer Recycling Behavior: Insights from Protection Motivation, Construal Level, and Regulatory Focus Theories [version 1; peer review: 1 approved, 1 approved with reservations]

The ever-increasing generation of municipal solid waste remains an environmental and managerial challenge. Understanding the psychological underpinnings of consumer recycling behavior (CRB) is essential for designing effective interventions. This study develops and tests an integrated conceptual model grounded in Protection Motivation Theory (PMT), Construal Level Theory (CLT), and Regulatory Focus Theory (RFT) to explain the motivational dynamics of CRB. Drawing on a cross-sectional survey of a convenient sample of Malaysian university students (N = 508), the model examines how threat and coping appraisals, psychological distance of environmental harm, and individual regulatory focus shape intention to recycle. Structural equation modeling results confirm that both threat appraisal (perceived severity and vulnerability) and coping appraisal (self-efficacy and response efficacy) significantly predict recycling intention, while perceived cost serves as a behavioral barrier. All four dimensions of psychological distance—temporal, spatial, social, and hypothetical—negatively predict threat appraisal, with perceived vulnerability showing stronger associations than perceived severity. Mediation analyses reveal that threat appraisal fully mediates the effect of psychological distance on recycling intention. Furthermore, the PORCESS analysis conducted to test moderated mediation hypotheses supports the role of regulatory focus: prevention focus attenuates the impact of psychological distance via severity perception, while promotion focus strengthens it. Findings highlight the interplay between cognitive appraisals, perceived distance, and motivational orientation in shaping pro-environmental intentions, offering actionable insights for the design of targeted recycling campaigns and public communication strategies. Implications for theory and policy, as well as directions for future research, are discussed.
