Assessment of Preferences for Delivery of Spine Care Information: A ChatGPT and Survey-Based Study

Abstract

Study DesignSurvey-based study.ObjectiveTo identify how to effectively tailor spine care information to different educational backgrounds, beyond general readability.MethodsAn internet-based survey (Connect™, CloudResearch) recruited 600 U.S. adults evenly distributed across age brackets (18-80). <i>Participants were presented with six clinical scenarios, each with a question, five answer choices, and asked to choose the most sensible answer.</i> ChatGPT-4 generated five response levels per question, scored with the Flesch Reading Ease scale to represent varying educational or readability levels. Chi-squared tests and standardized residual analysis compared preferred reading levels across education groups.ResultsOf the 600 participants (mean age 45 ± 15.7, 50.8% female), preferred selections were postgraduate (50.6%) and 8th-12th grade levels (22.1%). Bachelor's degree holders significantly favored postgraduate-level content (55.3%), while postgraduate respondents predominantly preferred 8th-12th grade or simpler (56.2%). Participants with less than a bachelor's degree similarly preferred 8th-12th grade or lower (53.5%). Standardized residual analysis revealed bachelor's participants selected postgraduate content more frequently than expected, whereas postgraduate and below-bachelor participants selected it less than expected.ConclusionsWhile postgraduate-level responses were the most frequently selected overall, preferences varied substantially by education level. Both postgraduate and below-bachelor participants tended to favor simpler content, while bachelor's-level respondents consistently preferred more complex language. These findings underscore that simplifying medical information may improve accessibility across diverse educational backgrounds. <i>When tailoring content by education level is not feasible, aiming for an 8th-12th grade reading level may offer the most effective balance between clarity and comprehensiveness in spine care communication.</i>
