Outcome Measures

Primary Outcomes (1)

  • Choice of Snack (Healthy vs. Unhealthy) Measured by Direct Observation

    At the baseline and right after the storybook intervention ends, each child will be offered a snack choice: fruit/vegetables (healthy) or cookies (unhealthy). The selection will be recorded using a standardized observation form. The primary outcome will be analyzed as the number and percentage of children selecting the healthy snack. Unit of Measure: Number and Percentage of Children Choosing a Healthy Snack

    Baseline (before intervention) and immediately after the storybook intervention ends (5 days of intervention).

Secondary Outcomes (3)

  • NutriSTEP Questionnaire (OBTA Questionnare)

    Baseline (before intervention) and immediately after the storybook intervention ends (5 days of intervention)

  • Nine-Item Avoidant/Restrictive Food Intake Disorder Screen (NIAS) Parent-Report

    Baseline (before intervention) and immediately after the storybook intervention ends (5 days of intervention)

  • Visual Scales

    Baseline (before intervention) and immediately after the storybook intervention ends (5 days of intervention)

Other Outcomes (3)

  • Height measurement

    At the baseline (before intervention) of the study.

  • Weight Measurement

    At the baseline (before intervention) of the study.

  • Body Mass Index Calculation and BMI z-scores

Interventions

In the first week, children in the intervention group were exposed to a structured, story-based nutrition education program. On the first day, the teacher read the designed storybook to the children for approximately 12-15 minutes. Children in the control group continued their routine classroom activities without exposure to nutrition-related content. During the remaining four days of the week, reinforcement activities were implemented to support the main message of the story, which emphasized the importance of fruit and vegetable consumption and healthy eating. These activities were developed in consultation with a child development specialist and were based on active learning and repetition principles. The reinforcement activities included age-appropriate tasks such as coloring, cutting, pasting, and drawing. Specifically, children participated in activities involving coloring story-related characters, selecting and pasting healthy food items onto visual materials, drawing their fa
