title: Application of an algorithm-driven protocol to simultaneously provide universal and targeted prevention programs.
abstract: OBJECTIVE
  Our objective was to develop a model to simultaneously prevent eating disorders and weight gain among female high school students.
  
  
  METHODS
  Of 188 female 10th graders enrolled in health classes, 174 elected to participate in the current study. They were assessed on-line and decided to participate in one of four interventions appropriate to their risk.
  
  
  RESULTS
  The algorithm identified 111 no-risk (NR), 36 eating disorder risk (EDR), 16 overweight risk (OR), and 5 both risks. Fifty-six percent of the EDR and 50% of the OR groups elected to receive the recommended targeted curricula. Significant improvements in weight and shape concerns were observed in all groups.
  
  
  CONCLUSIONS
  An Internet-delivered program can be used to assess risk and provide simultaneous universal and targeted interventions in classroom settings.
