Tóm tắt	The Ecological Footprint Knowledge Scale (EFKS) measures individuals' understanding of the ecological footprint concept—how much land and resources one's consumption requires—and knowledge of personal and global footprint impacts. Developed from the ecological footprint framework (Wackernagel & Rees, 1996), the EFKS assesses both conceptual comprehension (what is an ecological footprint?) and applied knowledge (how to estimate footprint, what factors affect it). The scale is critical for evaluating environmental education effectiveness, understanding why some individuals adopt sustainable consumption despite high footprint knowledge gaps, and identifying knowledge barriers that block behavior change.	The Environmental Concern Scale (ECS) measures the degree to which individuals worry about and feel affected by environmental problems, pollution, and ecological degradation. Originally developed by Weigel and Weigel (1978), the ECS focuses on emotional and affective responses to environmental issues—anxiety, worry, and perceived personal threat from pollution—rather than abstract values or beliefs. The scale is widely used in public opinion research, conservation communication effectiveness studies, and assessing emotional responses to environmental threats like climate change and air pollution.
