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.Design
A process evaluation study based on a systematic conceptual model.
Setting
Five middle schools in New York City.
Participants
Five hundred sixty-two students in 20 classes and their science teachers (n = 8).
Main Outcome Measures
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.
Analysis
Descriptive statistics and Spearman |?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 and Implications
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.
