概要	The New Ecological Paradigm (NEP) scale is the most widely used survey instrument for measuring an individual's general ecological worldview — the degree to which they see humanity as part of, and constrained by, a fragile and finite natural environment. Riley Dunlap and Kent Van Liere introduced the original New Environmental Paradigm in 1978 to capture the emerging post-materialist environmental consciousness, and Dunlap, Van Liere, Mertig, and Jones published the revised 15-item NEP scale in 2000, broadening its content and balancing pro- and anti-ecological items. Respondents rate agreement with statements about the balance of nature, limits to growth, anti-anthropocentrism, the fragility of nature's balance, and the possibility of an ecological crisis. Summing the balanced items yields a score of how strongly a person endorses an ecological versus a dominant social paradigm. The scale functions as a foundational worldview measure that predicts more specific environmental beliefs, attitudes, and behaviors, and it anchors much of quantitative environmental sociology.	The attitude-behavior-context (ABC) framework explains environmentally significant behavior as the joint product of internal attitudes and external contextual conditions, and crucially as their interaction rather than their sum. Gregory Guagnano, Paul Stern, and Thomas Dietz proposed it in 1995 using a natural experiment on curbside recycling, and Stern incorporated it into his 2000 theory of environmentally significant behavior. The core claim is that attitudes most strongly drive behavior when external conditions are neutral — neither strongly enabling nor strongly blocking the action — and that when context is overwhelmingly favorable or prohibitive, behavior is determined by the context regardless of attitude. Providing recycling bins, for example, raises recycling so much that pro-environmental attitudes add little, while in the absence of any collection even strong attitudes cannot produce the behavior. The framework reconciles the often weak and inconsistent attitude-behavior correlations in environmental research by treating context as a moderator. It is typically estimated as an interaction regression and complements value-belief-norm theory.
