Children in the virtual reality (VR) group watched a 360° Ice Age video via headset starting three minutes before and continuing throughout the allergy test. The video, selected by pediatric experts, was age-appropriate, visually rich, and emotionally neutral. VR provided immersive distraction to reduce pain, fear, and anxiety. After the test, children and parents rated pain (WBFPS), fear (CFS), anxiety (CAS-S), and satisfaction through structured forms.

The Wong-Baker FACES scale includes six facial expressions scored from 0 ("No Pain") to 10 ("Worst Pain"). Children select the face that best represents their pain. Valid for ages 3-18, it is widely used for its simplicity and strong psychometric properties and has been translated into many languages, including Turkish.

The Child Fear Scale consists of six facial expressions scored from 0 (no fear) to 10 (highest fear) in increments of two. Fear increases progressively across the faces. Its validity and reliability were confirmed by Avşan et al. (2024), and it aligns with pain scales in format and scoring.

The Child Anxiety State Scale (CAS-S), developed by Ersig et al. (2013), was validated in Turkish by Özalp Gerçeker et al. (2019). Designed for children aged 4-10, it resembles a thermometer and measures current anxiety ("right now"). The scale has strong psychometric properties and is suitable for clinical use.

The Visual Analog Scale (VAS) for care satisfaction was used to evaluate children's satisfaction with the care received during the allergy testing procedure. Children were asked to indicate their level of satisfaction on a scale ranging from "0 - Not satisfied at all" to "10 - Very satisfied."
