Domain sets and measurement instruments on participation and environmental factors in spinal cord injury research

The understanding and measurement of participation and environmental context in spinal cord injury (SCI) is critically important. However, there is limited understanding of the environment-participation relationship in SCI research. There is little consensus on what is and on how to measure participation and its environmental determinants in the SCI. The objective of this article is to develop a set of International Classification of Functioning, Disability and Health (ICF)-based SCI Participation and Environment Domain Set and measurement instruments that intend to measure those domains. ICF categories from the ICF components of activities and participation and environmental factors based on the comprehensive ICF Core Set for SCI and the ICF Core Set for vocational rehabilitation were merged. Measurement instruments were selected based on published systematic reviews of measurement instruments in SCI. There were 128 ICF categories or domains in total (38 for environmental factors and 90 for activities and participation). There were six measurement instruments on environmental factors and six for participation based on existing systematic reviews. This article presents a domain set that is relevant to conducting research on the social and environmental perspectives, in an effort to understand and measure functioning in SCI (i.e., "SCI participation domain set" and "SCI environment domain set," respectively). The sample of SCI Participation and Environment Measurement Instruments gathered indicate the comprehensiveness and depth of the different domains. Guiding principles on the utilization of these measurement instruments depending on the purpose and design of a research study are highly recommended to investigators.
