Trans-adapting outcome measures in rehabilitation: Cross-cultural issues.

Most outcome measures in rehabilitation are developed in the US and are later translated and used in the international rehabilitation community. Translating or rather trans-adapting outcome measures is an important process by which treatment efficacy can be proven and comparability can be established across cultures. This article explores some of the pitfalls the lack of adherence to international trans-adaptation guidelines can result in. We recommend the application of increased use of these guidelines in order to improve the quality of trans-adaptation, strengthen the international rehabilitation community's scientific position, and provide enhanced services to our patients.
