Anatomy of positive messages in healthcare consultations: component analysis of messages within 22 randomised trials

Background: Patients desire both honesty and hope from their healthcare practitioners. A recent systematic review of 22 randomised trials found that healthcare practitioners who deliver positive messages improve patient outcomes, most notably by reducing pain. However, the verbal and non-verbal components of positive messages within these trials varied greatly, which presents a barrier to the implementation of person-centered care. Objective: This study investigates common components of positive messages within the reviewed trials. Methods: We extracted the verbal and non-verbal language used to deliver positive messages in 22 trials from a recent systematic review. Three independent researchers coded the components of the messages using content analysis. Results: Positive messages in our sample had between 2 and 18 different components. These were clustered into 5 areas: specifying the positive outcomes, making the message personal, drawing on associations and meanings, providing a supportive psychological context and providing a rationale. Messages were reinforced through repetition in half the studies. Within the clusters, the most common components of positive messages were suggestions of specific effects (18 studies) and personalised formulations (15 studies). Most studies did not describe the components of positive messages adequately. Conclusions: Positive messages within randomized trials are complex interventions, with most including strong suggestions about specific effects, presented confidently and made personally relevant to the individual patient. Future trials of positive messages should report all components of these interventions.
