WASSP: A Review of its Clinical Application Internationally

Anne Ayre, Per Knudsen and Louise Wright

The Wright and Ayre Stuttering Self-Rating Profile (WASSP, 2000) has been used internationally for assessment, planning therapy and outcome measurement. A review of WASSP was carried out to consider revision and recommendations. Staff from the Stuttering Information Center of Denmark obtained permission to translate WASSP for use in Denmark. They adopted a systematic process in relation to the translation and followed the same method of reliability testing as the authors of WASSP. This paper will reflect on issues, in relation to validity and reliability, which arise when using a clinical tool in a different cultural context, language or age group.
