Does the Narrative Voice Influence Parental Perceptions of Pediatrician Blogs?

Abstract

To determine parental perceptions of pediatrician blog posts by narrative voice. Three blog posts each on 2 topics (vaccines and sleep) were written by an established physician blogger and varied by narrative voice (personal, third person objective and mixed). Topics were chosen to be applicable to all parents. Blog posts were evaluated by a communications expert, 2 research investigators, and 3 parents to confirm differences in narrative voice. We sampled parents of children 0 to 18 years old in 4 primary and subspecialty care clinics, and 1 inpatient medical unit. Participants were randomized to read 2 blog posts (1 per topic) that varied by narrative voice. Participants rated their perceptions of the accuracy, reliability, and appeal for each blog posts on a 5-point Likert Scale. The Kruskal-Wallis test was used to compare the distribution of parental rankings for accuracy, reliability, and appeal. The average participant age (n=258) was 39.8 (SD 9.7), 83% were female. Blog posts written in the third person objective voice were rated as more accurate and reliable than those in the personal or mixed voice. There was effect modification by topic, with parents rating the sleep blog posts as more accurate than the vaccine blog posts. There was no difference in the appeal of information by narrative voice or topic of blog post. The narrative voice used to convey information on pediatrician blog posts can influence reader perception of accuracy and reliability. Physician bloggers can enhance parental trust of their content using study findings.
