The Revised Pro-Environmental Behavior Scale (R-PEBS) is a psychometric tool used to measure the frequency and extent of individuals' engagement in behaviors that promote environmental sustainability. The scale helps identify specific actions that people take in their daily lives to reduce their ecological footprint and contribute to environmental conservation. The revised version aims to improve clarity and relevance, adapting to modern environmental challenges.

Respondents typically rate their frequency of engaging in these behaviors using a Likert scale (e.g., from 1 = "never" to 5 = "always"). The total score reflects the individual's overall level of pro-environmental behavior. Higher scores suggest a greater commitment to sustainability and ecological responsibility.

(QUALYs) is a measure used to evaluate the value of health outcomes by considering both the quantity (years of life) and quality of life. It's a widely used metric in health economics, especially for cost-effectiveness analyses of healthcare interventions. QUALYs combine life expectancy with a weighting factor representing the quality of life during those years, where 1 represents perfect health and 0 represents death.

Healthcare and social system utilization refers to the frequency and types of services used by individuals, while cost savings in this context involves reducing the financial burden on these systems through efficient resource use, preventive measures, or improved treatment outcomes. Cost savings in healthcare and social services can be measured through reduced hospital visits, fewer medications, shorter hospital stays, or less reliance on long-term care services.

The primary aim of assessing healthcare utilization and cost savings is to analyze how specific interventions or programs (such as lifestyle changes, treatments, or preventive health measures) can improve health outcomes while reducing the costs incurred by the healthcare and social systems.

Willingness to Pay (WTP) refers to the maximum amount an individual is willing to pay for a specific good or service, reflecting their perceived value of that item. In health economics, WTP is often used to gauge how many individuals value health improvements, treatments, or healthcare interventions.

The Nature Connectedness Index (NCI) is a psychological measure designed to assess an individual's emotional and cognitive relationship with nature.

Resilience refers to the capacity to adapt and thrive in the face of adversity, stress, or trauma.

The PSS consists of a series of questions that assess various aspects of perceived stress over a specific time frame (usually the past month). The PSS can be administered in different versions, commonly consisting of 10 or 14 items. Participants respond using a 5-point Likert scale (0-4). Th scores for each item are summed to produce a total score, which can range from 0 to 40 (in the 10-item version) or up to 56 (in the 14-item version). Scores can be categorized into ranges (e.g., low, moderate, high stress) to help assess individuals' stress. Higher scores indicate higher levels of perceived stress.

The OECD-4 refers to a set of four indicators used by the Organisation for Economic Co-operation and Development (OECD) to assess subjective well-being and quality of life among individuals and populations. This framework aims to provide a comprehensive understanding of well-being beyond traditional economic measures, focusing instead on people's perceptions of their lives.

The OECD-4 indicators provide a valuable framework for assessing subjective well-being and quality of life. By focusing on life satisfaction, positive and negative feelings, and overall health, the OECD-4 offers insights into individuals' perceptions of their lives and well-being.
