摘要	Environmental barriers measurement is the general methodological strategy for assessing the environmental-factors component of the WHO ICF, which conceives disability as the product of an interaction between a person and the world they inhabit. Rather than a single questionnaire, it is an approach: enumerate the relevant environmental domains defined by the ICF — products and technology, the natural and built environment, support and relationships, attitudes, and services, systems, and policies — and then characterize each factor by its valence (whether it acts as a barrier or a facilitator) and its extent. Because the ICF treats the environment as something that can either hinder or help, the strategy deliberately measures both negative and positive influences rather than only obstacles. The assessed factors are then linked statistically to participation outcomes, and the deeper aim is to model the interaction between a person's capacity and their environment, so that the disabling or enabling role of context can be estimated. Specific instruments such as the Craig Hospital Inventory of Environmental Factors are particular realizations of this broader strategy.	Person-environment fit is an analytic framework that treats disability not as a property of the individual but as a misfit between a person's capacity and the demands their environment places on them. Rooted in ecological models of aging and disability — most famously the competence-press model, in which behavior depends on the balance between personal competence and environmental press — it aligns closely with the biopsychosocial conception of the WHO ICF, where disability emerges from the interaction of the person and contextual factors. The framework asks, for any activity or life situation, whether the environment demands more than the person can supply: when demand exceeds capacity there is misfit and disability is expressed, and when demand is within capacity there is adequate fit and participation proceeds. Crucially, this reframing implies that misfit can be reduced from either side — by raising the person's capacity or, often more powerfully, by lowering environmental demand and adding support. The practical thrust is to target interventions on the environment, not only on remediating the person.
