The Effect of Text Versus Video Presentations of Patient Narratives in a Web-based Patient Decision Aid

摘要

Over the past several years the Internet has developed a more prominent role as a source for medicalpatients to search for health related information. The current study examined the use of web-basedpatient decision aids and how the format of patient narratives influenced treatment preferences andknowledge about the treatments options. Fifty-three women viewed a web-based decision aid withpatient narratives displayed in a full-video format, full-text (no video) format, no patient video format,or no patient text format. The patient narrative format had no influence on knowledge or treatmentpreference, but time spent viewing specific webpages within the decision aid was predictive oftreatment choice. Participants that spent more time viewing the lumpectomy webpage were significantlymore likely to prefer lumpectomy with radiation, while participants who spent more time viewing themastectomy webpage were significantly more likely to prefer mastectomy. These results suggest that aconfirmation bias may be present.
