Medical Metaphors That May Reinforce Misconceptions Are Associated With Increased Trust in the Clinician.

BACKGROUND AND OBJECTIVES:This study measured patient reactions to medical metaphors used in musculoskeletal specialty offices and asked: (1) Are there any factors associated with patient thoughts and emotions in response to common metaphors? (2) Is there a difference between patient ratings of metaphors rated as potentially reinforcing misconceptions and those that are more neutral? METHODS:In a cross-sectional study, 228 patients presenting to multiple musculoskeletal specialty offices rated reactions to 4 metaphors presented randomly from a set of 14. Two were categorized as potentially reinforcing common misconceptions and 2 as relatively neutral. Bivariate tests and multivariable regression identified factors associated with patient ratings of levels of emotion (using the standard assessment manikins) and aspects of experience (communication effectiveness, trust, and feeling comfortable rated on 11-point ordinal scales) in response to each metaphor. RESULTS:Levels of patient unhelpful thinking or distress regarding symptoms were not associated with patient ratings of patient emotion and experience in response to metaphors. Metaphors that reinforce misconceptions were associated with higher ratings of communication effectiveness, trust, and comfort (P < .05). CONCLUSION:The observation that metaphors that validate a person's understanding of his or her illness may elicit trust even if those metaphors have the potential to reinforce misconceptions may account for the common usage of such metaphors. Clinicians can work to incorporate methods for building trust without reinforcing misconceptions.
