title: Participant satisfaction with appearance-based versus health-based educational videos promoting sunscreen use: a randomized controlled trial.
abstract: BACKGROUND
  Increasing participant satisfaction with health interventions can improve compliance with recommended health behaviors and lead to better health outcomes. However, factors that influence participant satisfaction have not been well studied in dermatology-specific behavioral health interventions. We sought to assess participant satisfaction of either an appearance-based educational video or a health-based educational video promoting sunscreen use along dimensions of usefulness of educational content, message appeal, and presentation quality.
  
  
  METHODS
  In a randomized controlled trial, participants were randomized 1:1 to view an appearance-based video or a health-based video. After six weeks, participant satisfaction with the educational videos was assessed.
  
  
  RESULTS
  Fifty high school students were enrolled and completed the study. Participant satisfaction ratings were assessed using a pre-tested 10-point assessment scale. The participants rated the usefulness of the appearance-based video (8.1 ± 1.2) significantly higher than the health-based video (6.4 ± 1.4, p<0.001). The message appeal of the appearance-based video (8.3 ± 1.0) was also significantly higher than the health-based video (6.6 ± 1.6, p<0.001). The presentation quality rating was similar between the appearance-based video (7.8 ± 1.3) and the health-based video (8.1 ± 1.3), p=0.676.
  
  
  CONCLUSIONS
  Adolescents rated the appearance-based video higher than the health-based video in terms of usefulness of educational content and message appeal.
