The Development and Validation of the Partial Denture Experience Questionnaire (P-DEQ): Reliability and Validity.

The P-DEQ demonstrates promising reliability and content validity for assessing the complex experience of living with a removable denture. The instrument is sensitive to the nuanced, often ambivalent, emotional states of wearers. Whilst this initial validation is based on cross-sectional data, longitudinal testing is required for item reduction and to fully establish the P-DEQ as a robust measure that can detect change over time.
