A comparison of videotape and audiotape assessment of patient-centredness in family physicians' consultations

Abstract

The aim of this study was to compare videotape and audiotape assessments of doctors' patient-centred behaviour in primary care consultations. The patient-centredness scale of Henbest and Stewart was used to measure the quality of 856 doctor-patient interactions in 258 consultations performed by 47 primary care physicians recorded on videotape. Assessments were performed once using only the sound track and a second time using both the sound and video-tracks. On a nominal quality scale of 0-3, the average score for all consultations was 1.94 (S.D. 0.63) by audio assessment, and 1.94 (S.D. 0.59) by video assessment (P<0.8). There was excellent agreement between audio and video scores over a wide range of scores. Little information (<5%) was lost when using audiotape compared to videotape. It was technically easier to assess the video recordings. Audio recording is equivalent to video recording for the assessment of patient-centredness using the scale of Henbest and Stewart in primary care consultations.
