title: C U L8ter: YouTube distracted driving PSAs use of behavior change theory.
abstract: OBJECTIVE
  To examine the inclusion of health behavior theory in distracted driving PSAs on YouTube.com.
  
  
  METHODS
  Two-hundred fifty PSAs were assessed using constructs from 4 prominent health behavior theories. A total theory score was calculated for each video. Multiple regression analysis was used to identify factors associated with higher theory scores.
  
  
  RESULTS
  PSAs were generally lacking in theoretical content. Video length, use of rates/statistics, driving scenario depiction, and presence of a celebrity were positively associated with theory inclusion.
  
  
  CONCLUSIONS
  Collaboration between health experts and PSA creators could be fostered to produce more theory-based distracted driving videos on YouTube.com.
