The development of a Dutch protocol for perceptual speech analysis and quality of life measurements in cleft palate patients.

A protocol for perceptual speech analysis in cleft palate patients will be developed. This protocol is based on the CAPS-A protocol (John et al., 2006). Also a questionnaire concerning quality of life in these patients will be developed. The translation guidelines of Varni (2003) will be used. For both instruments the validity and reliability will be extensively tested.
