摘要：2.1 Background Intervention research typically assesses the impact of one intervention intended to produce a desired change or outcome. Often, however, the context of the setting or needs of the participants reveal multiple points of intervention that could be addressed to achieve the desired outcome. This possibility is especially likely when the research takes place in the real‐life context of community participation among people with disabilities. For example, many people with disabilities have difficulty attaining competitive employment (an outcome that provides the person with a disability with direct access to his/her community). Previous research identified numerous barriers to employment, including but not limited to poor social skills, lack of work experience, lack of transportation, discriminatory hiring practices, and lack of needed on‐the‐job supports. Each of these barriers presents a possible point for intervention.
