Understanding public perceptions toward sustainable healthcare through psychological network analysis of material preference and attitudes toward plastic medical devices
Summary
This paper is not about microplastics; it surveys public attitudes and preferences toward sustainable versus conventional plastic materials used in medical devices, using psychological network analysis.
Recent and potential future health-care users (i.e., the public) are important stakeholders in the transition toward environmentally sustainable healthcare. However, it remains unclear whether, according to the public, there is room for sustainable innovations in materials for plastic medical devices (PMD). This study explores preferences regarding conventional or bio-based PMD, and psychological mechanisms underlying these preferences. We administered two surveys among Dutch adults from a research panel. Results from the first survey (i.e., open-text survey on attitude elements; NStudy1 = 66) served as input for the second survey (i.e., Likert-scale survey on beliefs, emotions, perceived control, social norms, trust, related to current and bio-based PMD, and health and age; NStudy2 = 1001; Mage = 47.35; 54.4% female). The second survey was completed by 501 participants who, in the last two years, received care in which PMD were used, and 500 participants who did not. Cross-sectional psychological networks were estimated with data from the second study using the EBICglasso method. Results showed that participants preferred bio-based over conventional PMD, and this applied regardless of whether devices are used inside or outside of the body. Results also showed emotions play an important role, with emotions regarding bio-based PMD being strongly related to preference. Furthermore, comparing recent and potential future receivers of PMD revealed differences in preference but comparable relations between preference and other psychological variables. This study shows that receivers’ perspectives should not be seen as potential barriers, but as additional motivation for transitioning toward sustainable healthcare. Recommendations for implementation are discussed.

Explicitly and Implicitly Measured Valence and Risk Attitudes Towards Plastic Packaging, Plastic Waste, and Microplastic in a German Sample
This psychology study measured both explicit and implicit attitudes toward plastic packaging and microplastics in German consumers, finding that people simultaneously appreciate the convenience of plastic while expressing concern about pollution. The gap between attitudes and behavior helps explain why plastic consumption continues despite public concern about microplastics.
A community-based cross-sectional study exploring knowledge, attitude, and practice of adults towards the use and hazards of plastic products
A community-based cross-sectional study explored public knowledge, attitudes, and practices around plastic use and health risks, finding gaps in awareness of plastic chemical components despite widespread daily use. The authors recommend targeted public education to promote healthier and more sustainable plastic choices.
Do attitude towards behavior, subjective norms, and perceived control behavior matter on environmentally friendly plastic purchasing intention?
This study investigated whether attitude toward behavior, subjective norms, and perceived behavioral control predict consumer intention to purchase environmentally friendly plastic products, using questionnaire data collected via social media platforms. The findings provide empirical support for the Theory of Planned Behavior as a framework for understanding sustainable plastic purchasing decisions.
Exploring the psychological antecedents of private and public sphere behaviours to reduce household plastic consumption
Researchers surveyed 648 people to understand what psychological factors drive different plastic-reduction behaviors — switching to plastic-free products, political activism, and supporting policy. Personal moral norms predicted all three types of action, while feeling personally capable was the strongest driver of purchase decisions, suggesting that reducing plastic use requires addressing both values and practical barriers.
Public perception of microplastics pollution in Switzerland: Psychological distance, concern, and willingness to engage in mitigation activities
Researchers surveyed over 900 people in Switzerland to understand how the public perceives microplastic pollution and their willingness to take action. The study found that people perceive microplastics as a relatively close threat on most psychological dimensions, and that concern about the issue, particularly concern for nature, is a stronger predictor of willingness to engage in mitigation activities than psychological distance alone.
