Breaking the plastic habit: Drivers of single-use plastic reduction among Thai university students.

This study investigated the decision-making dynamics for pro-environmental behavior among Thai university students, focusing on reducing the consumption of single-use plastics (SUP). By adopting a dynamic approach to the Theory of Planned Behavior (TPB), the research examined the influence of psychosocial factors, including attitudes, perceived behavioral control, and subjective norms, on SUP reduction intention at different phases of behavior change. Using structural equation modelling, we analyzed quantitative data (n = 317) from the selected universities. The results revealed that attitudes predicted behavioral intentions only among individuals in the contemplation phase of reducing SUP. Attitudes had a small but limited influence on the behavioral intentions of students who had not yet acted. Perceived behavioral control, on the other hand, significantly impacted behavioral intentions across all phases of behavior change, highlighting its importance in SUP reduction. The study also confirmed subjective norms' positive influence on students' behavioral intentions in the pre-contemplation phase. Practical implications suggested segmenting residents based on their behavior change phase so that public policymakers can allocate resources more efficiently and effectively by tailoring campaigns to specific behavior change phases, ultimately promoting sustainable behavior among university students.

Pro-environmental behavior regarding single-use plastics reduction in urban-rural communities of Thailand: Implication for public policy.

The study investigates residents' behavior towards reducing the use of single-use plastic (SUP), specifically in the context of food packaging. The widespread view holds that pro-environmental behavior (PB) results from a person's moral and rational deliberations. In reducing single-use plastic (SUP) consumption and waste, the relative roles of rationality and morality models in validating PB among rural and urban residents are not yet clear. In this empirical study, we compared the relative efficacy of two models for explaining people's SUP reduction behavior: the theory of planned behavior (TPB; rationality) and the value belief norm (VBN; morality). We investigated Thailand's rural (Sichang Island) and metropolitan (Nonthaburi city) areas. As a result, we surveyed people living on Sichang Island (n = 255) and in Nonthaburi city (n = 310). We employed structural equation modeling (SEM) for data analysis in this study. Findings showed that while morality better justified all the study participants' SUP reduction behavior, rationality underpinned behaviors of rural residents, while morality better explained the actions of city residents. We discussed future theoretical development and a policy roadmap based on these findings.

Identifying the determinants of face mask disposal behavior and policy implications: An application of the extended theory of planned behavior.

A study in Nigeria examined the psychological factors affecting face mask disposal behavior (DB) during the COVID-19 pandemic. The Theory of Planned Behavior (TPB) was used, with awareness of consequences and institutional barriers added. 1183 respondents completed an online survey, and structural equation modeling was used to analyze the data. The original TPB model revealed that attitudes, perceived behavioral control, and subjective norms explained 65% of the variance in respondents' behavior. Behavioral intention and perceived behavioral control accounted for 59.3% of the variance in DB. The extended TPB model, which included awareness of consequences and perceived institutional barriers, improved the model's explanatory power by 12.8%. Both TPB models adequately predicted face mask (FM) disposal behavior, with implications for policymakers and waste management authorities to design interventions to promote proper FM disposal behavior.

Pesticide Safety Behavior among Cocoa Farmers in Nigeria: Current Trends and Determinants.

BACKGROUND: There is a strong link between pesticide exposure risk and farmers' safety behavior. However, there is a lack of understanding of farmers' safety behavior in pesticide use and the psychological factors that influence it, especially in Nigeria. OBJECTIVE: This study aimed to identify safety behaviors in pesticide use and their determinants among cocoa farmers in Nigeria using the Health Belief Model (HBM). METHODS: We used a suitable questionnaire to retrieve data from 391 cocoa farmers across three major cocoa-producing belts in Nigeria. The data were analyzed using both descriptive and inferential statistics. RESULTS: Findings showed that cocoa farmers in this study sprayed insecticides, herbicides, and fungicides on their cocoa farms. The study revealed that most pesticides were not approved for cocoa production by the authority, but the farmers were still using them. The study participants overused surveyed pesticides as the quantities applied were beyond the recommended dosage by the manufacturers. Correlation analysis showed a relationship between education status, pesticide training, perceived susceptibility and cue to action, and the farmers' pesticide overuse. In all, 42.7% of the farmers showed unsafe behaviors, 49.1% showed intermediate behaviors, and just 8.2% reported safe behaviors in pesticide use. Multiple linear regression analysis showed that perceived barriers, susceptibility, self-efficacy, and cue to action were related to age, education status, and farm experience and accounted for 59.3% of the total variance in the farmers' pesticide safety behaviors. Perceived barriers had the most significant negative influence on the farmers' behaviors, while perceived susceptibility, self-efficacy, and cue to action positively influenced the farmers' behavior. CONCLUSION: Future intervention programs in Nigeria incorporating significant variables, especially perceived barriers, in their designs with proper implementation could be more effective.

Using the Socio-Ecological Model to Frame the Influence of Stakeholders on Cocoa Farmers' Pesticide Safety in Nigeria: Findings from a Qualitative Study.

PURPOSE: The aim of this study was to explore the roles of stakeholders on cocoa farmers' safe pesticide use in Nigeria using the socio-ecological model as the theoretical framework. METHODS: This was a cross-sectional qualitative study where participants were purposefully selected based on some criteria. Then, they were interviewed in-depth using a semi-structured interview approach. The interview guide was designed based on other literature and the study objectives. The interview transcripts were transcribed verbatim and analyzed using the content analysis technique. RESULTS: In all, 57 participants were involved in the interview process across all the study locations. Five layers of influence (cocoa farmers, pesticide retailers, extension officers, pesticide importers and government agencies) were considered. At individual level, cocoa farmers complained about lack of information from other stakeholders regarding pesticide use except retailers due to the farmers' proximity to their stores. However, pesticide safety information from the retailers were found to be inadequate due to their interest in financial gains rather than a focus on human health and the environment. Additionally, most retailers had no understanding about the characteristics of products they sold as they could not read pesticide labels. Furthermore, lack of motivations, human resources and facilities hindered effective extension education in the rural communities. Also, pesticide importers took efforts to train the farmers within their network, but majority of these trainings focused on lead farmers who were expected to disseminate the information to others. Besides, the agencies did organize training or workshop sometimes, but it was inadequate due to budget constraint. Lastly, environmental or agri-policies relating to Nigerian cocoa farmers concerning safe pesticide use and disposal were also inadequate. CONCLUSION: Generally, there was a large information gap with respect to pesticide safety between cocoa farmers and other stakeholders which undermined pesticide use safety. This study highlighted the need for government agencies in Nigeria to develop mechanisms to monitor information exchange among other stakeholders and cocoa farmers with respect to safe pesticide use and disposal.
