title: Using a systematic conceptual model for a process evaluation of a middle school obesity risk-reduction nutrition curriculum intervention: choice, control & change.
abstract: OBJECTIVE
  To use and review a conceptual model of process evaluation and to examine the implementation of a nutrition education curriculum, Choice, Control & Change, designed to promote dietary and physical activity behaviors that reduce obesity risk.
  
  
  METHODS
  A process evaluation study based on a systematic conceptual model.
  
  
  METHODS
  Five middle schools in New York City.
  
  
  METHODS
  Five hundred sixty-two students in 20 classes and their science teachers (n = 8).
  
  
  METHODS
  Based on the model, teacher professional development, teacher implementation, and student reception were evaluated. Also measured were teacher characteristics, teachers' curriculum evaluation, and satisfaction with teaching the curriculum.
  
  
  METHODS
  Descriptive statistics and Spearman ρ correlation for quantitative analysis and content analysis for qualitative data were used.
  
  
  RESULTS
  Mean score of the teacher professional development evaluation was 4.75 on a 5-point scale. Average teacher implementation rate was 73%, and the student reception rate was 69%. Ongoing teacher support was highly valued by teachers. Teacher satisfaction with teaching the curriculum was highly correlated with student satisfaction (P < .05). Teacher perception of amount of student work was negatively correlated with implementation and with student satisfaction (P < .05).
  
  
  CONCLUSIONS
  Use of a systematic conceptual model and comprehensive process measures improves understanding of the implementation process and helps educators to better implement interventions as designed.
