Methods and Findings of the Evaluation of the Intervention Program

ComponentMethods of EvaluationKey Findings
1. Training of kindergarten staff1. Interview of preschool staff focusing on the appropriateness of the content1. Acceptability for the course on general nutrition knowledge was high. Preschool staff found it useful and the level was appropriate. Some kitchen staff thought the catering software was too advanced for them due to their relatively lower educational level.
2. Pre- and postcourse questionnaires testing the understanding of core content and the use of the catering software2. Nonetheless, after training, 76% of the kitchen staff were able to operate the software on their own.
3. Awareness and attendance of preschool staff in the courses3. Overall, 96% of the preschool staff were aware of the courses. Attendance was also high at 93%.
2. A curriculum promoting healthy diet and lifestyle1. Interview of preschool staff focusing on the appropriateness of the curriculum1. Teachers who were responsible for delivering the health education lessons had positive feedback and thought the content was appropriate.
2. Observation of sessions to learn satisfaction and acceptance of teachers and children.2. The “healthy activities,” although acceptable to the children, the timing (after lunch) was impractical because it shortened the lunch break (which includes a nap). Nevertheless, dancing in the activity room was highly acceptable to children and preschool staff.
3. Questionnaires for parents on their knowledge of their children’s dietary habits and health behaviors3. Parents’ response showed that they were familiar with their children’s dietary habit and health knowledge.
3. Collaboration between families and schools1. Interview of parents and preschool staff1. Parents were too busy to attend all the lectures. They were more prepared to attend twice: at the start and during the intervention. Parents liked the idea of tracing their children’s growth curve, although they found the lecture material difficult.
2. Awareness and attendance of parents in the courses2. This was reflected by a high awareness at 92% but a lower attendance rate at 69%.
3. Compliance and usefulness of the handbook3. Parents would welcome the feedback to be sent via text messages or a smartphone app. However, they still preferred to use a handbook as a means to communicate with the teachers. On average, 96% of the handbooks were handed in on time; 99% of the children in the intervention group had a complete set of BMI records.
