title: The Burdens in Prosthetic Dentistry Questionnaire (BiPD-Q): development and validation of a patient-based measure for process-related quality of care in prosthetic dentistry.
abstract: OBJECTIVE
  To develop and validate an instrument for the assessment of patient-based measures of process-related quality of care in prosthodontic patients.
  
  
  METHODS
  In this nonrandomized study, the new Burdens in Prosthetic Dentistry Questionnaire (BiPD-Q) was developed in two steps using a total of 128 prosthodontic patients in a mixed-method approach, combining quantitative-qualitative methodologies. First, the item pool for the instrument was created using semistructured interviews and a group of experts in prosthodontics. This resulted in a preliminary version of the questionnaire. Second, an assessment of redundancy, completion rates, face validity, difficulty, and distribution of the core set of the items was performed. The final version of the BiPD-Q had psychometric core properties (reliability and validity) evaluated.
  
  
  RESULTS
  The BiPD-Q consisted of 25 items. Reliability was satisfactory (Cronbach's alpha = .87). The mean score of all items of the BiPD-Q was significantly correlated with mean perceived burdens during treatment as rated by the clinician (r = 0.26; P < .01) and with overall satisfaction with the treatment procedures as rated by patients (r = .31; P < .01), indicating sufficient convergent validity.
  
  
  CONCLUSIONS
  A reliable and valid instrument for the assessment of patient-based process-related quality of care in prosthodontics has been developed. The BiPD-Q allows comparisons of different dental procedures within a treatment course and of different treatment providers. The use of this type of questionnaire appears to be a valuable tool for dental health care research. The outcomes of research using the BiPD-Q may result in a more pleasant treatment experience for future patients.
