Development of the Patient's Experience and Attitude Colposcopy Eindhoven Questionnaire (PEACE-q).

ABSTRACT

BACKGROUND: No validated instruments for the evaluation of patient satisfaction in colposcopy do exist. Therefore, this study reports on the development of a Patient's Experience and Attitude to Colposcopy questionnaire. METHODS: Patients who recently received colposcopy participated in a focus group. A panel of experts evaluated the transcriptions and agreed on a 15-item draft questionnaire. The draft questionnaire was completed by 68 women who subsequently came for a colposcopy. For construct validation, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed as well as reliability analysis. Concurrent validity was assessed with the 4-item Patient Health questionnaire (PHQ-4). RESULTS: Construct validation resulted in an 8-item patient perception scale with good psychometric properties (Cronbach's alpha 0.76) and excellent model fit. Two subscales could be discriminated patient procedure perception scale (alpha 0.89) and caregiver attitude perception scale (alpha 0.71). Both subscales intercorrelated moderately (r = 0.28, p = 0.045). The subscale patient perception correlated significantly with the PHQ-4 scale and its anxiety subscale, not with the depression subscale. CONCLUSIONS: We developed a Patient's Experience and Attitude to Colposcopy questionnaire with adequate psychometric properties. Future application in out-patient clinics should further evaluate its clinical relevance.
