About this study

This completed cluster randomized controlled trial evaluated the effectiveness of a play-based nasal hygiene education program on nasal hygiene knowledge and skills among preschool children. The study was conducted in the kindergarten level of a public primary school in Istanbul, Türkiye. Two preschool classrooms were randomly assigned to the intervention and control groups. The intervention group received a structured nasal hygiene education program including visual educational materials, an animation-based video, and play-based skill practice activities, while the control group received no education during the data collection period. Outcomes were assessed at baseline and two weeks after completion of the intervention using performance-based and video-recorded assessments. After post-test measurements, the education program was also provided to the control group.

Treatment and study plan

Play-Based Nasal Hygiene Education Program

Behavioral

The intervention consisted of a structured nasal hygiene education program developed for preschool children. The program included group-based education using visual educational materials, an animation-based educational video, and demonstration of nasal hygiene steps. It also included individual play-based practice stations: nasal air pressure development activities, nasal airflow performance activities, nasal hygiene sequencing cards, and a simulated nasal hygiene practice station. The program targeted both cognitive learning and psychomotor skill development.

Primary outcomes

  1. Change in Nasal Hygiene Knowledge Score

    Time frame: Baseline and two weeks after completion of the intervention

    Children's nasal hygiene knowledge was assessed using the Nasal Hygiene Knowledge Sequencing Test. The test consists of eight visual cards representing the steps of nasal hygiene. Children were asked to place the cards in the correct order. Each correctly ordered card was scored as 1 point and each incorrectly ordered card was scored as 0 points. Higher scores indicate a higher level of nasal hygiene knowledge.

  2. Change in Nasal Air Pressure Performance

    Time frame: Baseline and two weeks after completion of the intervention

    Nasal air pressure performance was assessed using the Nasal Air Pressure Measurement Test. A lightweight paper strip was fixed to the child's nasal bridge, and the child was asked to blow through the nose with the mouth closed. Performance was evaluated based on the angle difference between the baseline position of the paper and the maximum elevation angle achieved during nasal blowing. Higher angle differences indicate better nasal air pressure performance.

  3. Change in Nasal Airflow Performance

    Time frame: Baseline and two weeks after completion of the intervention

    Nasal airflow performance was assessed using the Nasal Airflow Performance Test. A lightweight pom-pom ball was placed inside a cardboard tube attached to a pediatric respiratory mask. Children were asked to blow through the nose with the mouth closed to move the pom-pom out of the tube. Performance was evaluated using two parameters: success in expelling the pom-pom from the tube and the time required to expel the pom-pom. Successful expulsion and shorter completion time indicate better nasal airflow performance.

  4. Change in Nasal Hygiene Skill Score

    Time frame: Baseline and two weeks after completion of the intervention

    Children's nasal hygiene skills were assessed using the Nasal Hygiene Skill Assessment Checklist. The checklist evaluates children's performance of nasal hygiene steps in a simulated environment. Each skill step was scored as "performed" = 3 points, "partially performed" = 2 points, and "not performed" = 1 point. Higher scores indicate better nasal hygiene skill performance. The performance was video-recorded and evaluated by independent observers.

Secondary outcomes

  1. Change in Parent-Rated Independent Nasal Hygiene Performance

    Time frame: Baseline and four weeks after completion of the intervention

    Parents evaluated children's independent nasal hygiene performance using a visual analog scale. Higher scores indicate a higher level of independent nasal hygiene performance.
