Testing a model of perceived information adequacy and uncertainty reduction in physician‐patient interactions

Abstract

Abstract This study, guided by information theory and uncertainty reduction theory, proposed and tested a model of perceived information adequacy and uncertainty reduction in doctor‐patient interactions. Fifty‐six patients in a cardiology clinic participated in the study which included a pre‐visit and a post‐visit survey. The results confirmed the existence of illness uncertainty, relational uncertainty, and medical setting uncertainty as perceptually related, but relatively distinct constructs. Results also indicated that perceived information adequacy is a valid predictor of post‐visit illness uncertainty. The model generally was supported. In addition, this study provides evidence for the reliability and validity of scales that were developed to measure sources of uncertainty and perceptions of information adequacy in doctor‐patient interactions. Discussion highlights consideration of practical implications, limitations, and directions for future research.
