It can be concluded that on the basis of empirical evidence, within the time frame of this literature search, little is known about community participation of people with ID. Many researchers did not clearly define community participation and were concerned with limited areas of community participation; research is seldom based on a theoretical framework. Most studies focus on people with mild ID, and there are few reports of the subjects' sample. However, one conclusion can consistently be drawn from the review: people with ID living in community settings participate more than people living in a segregated setting, but their participation level is still much lower than non-disabled and other disability groups.

It can be concluded that little has been published about the impact of environmental factors on community participation. Many studies do not clearly define the concept of community participation. Research on the impact of environmental factors on community participation so far seems not to be based on a theoretical framework. Most studies focused on the impact of services on community participation in general.

IMPACT-S is a reliable and valid generic measure of activity limitations and participation restrictions that fits the ICF.

Implementing effective interventions in general education increases the chances of success for students with disabilities. Often the effectiveness of interventions is not known. The aim of this review was to investigate what interventions are used in general education and what is known about their effectiveness so that educational institutions can exchange best practices and students with disabilities have better opportunities for successful participation in general education. A systematic literature search was conducted in four databases. Three investigators assessed the relevance of the studies identified. In only half of the studies is information on the effectiveness of interventions reported. Due to enormous variety in the types of interventions, effect measures, disability groups, and focus on different types of education, we chose to focus on reading interventions for improving the reading skills of students with reading and/or learning disabilities. Other interventions are shortly mentioned. All of the eight reading interventions found seem to have positive influences on reading skills. However, the methodological quality in some studies was low. Still, recommendations for actual interventions in general education are made. Measuring the effectiveness of interventions systematically and publishing the information helps others to implement effective interventions without having to reinvent them.

Language for all is a method developed in the Netherlands for providing information in such a way that as many intended readers as possible both comprehend and accept this information. Readers include people with a large variety of reading abilities including people with low literacy skills. Language for all can be characterized as a more accessible variant of plain language with some characteristics of easy language. In three studies the comprehension and acceptance of and preference for texts written in Language for all was evaluated, comparing original texts with a version in Language for all. Information written in Language for all was significantly better understood and accepted, and was preferable to the original version. In conclusion, Language for all is a promising effective, inclusive, and comprehensive method to provide information to people with and without low literacy skills. Further research is recommended.
