Development of the Zero-Waste Attitude Scale for College Students : Exploratory Factor Analysis and Reliability Verification
Summary
Researchers developed and validated a 19-item multidimensional scale to measure zero-waste attitudes in Korean college students, capturing four factors — environmental participation, resource circulation, microplastic and health awareness, and daily environmental practice — with a cumulative explanatory variance of 50% and strong reliability.
Purpose: Global environmental crisis and exposure to microplastics are emerging as serious health problems that threaten human health, and the importance of zero-waist practice is being emphasized. This study aims to develop a multidimensional 'zero-waist attitude measurement tool for college students' by reflecting the characteristics of domestic university students who have a high proportion of single-person households and are familiar with delivery culture and are vulnerable to disposable product consumption, and to verify its validity and reliability. Method: The questions were composed according to the methodological procedure of scale development. Item analysis, exploratory factor analysis (EFA), and reliability verification were conducted based on the data collected from 182 domestic university students. Results: As a result of factor analysis, the final scale composed of a total of 19 items was derived, including four sub-factors: 'environmental participation and social practice', 'resource circulation practice', 'microplastic and health impact', and 'environmental practice in life'. The cumulative explanatory variance of this scale was 50.01%, and the reliability of the entire tool was .83. Conclusion: The developed tool is a multidimensional scale that goes beyond the existing fragmentary recycling measurement, and encompasses the perception of the health risk of microplastics and environmental hormones and the trend of SNS-based social practice of college students. This can be used as a useful indicator to evaluate the needs of environmental health education programs for college students in the future and the effectiveness of health promotion interventions.
