About this study
Official title: Development and Validation of the Air Quality Awareness Scale (AQAS) for Parents of Children With Allergic Diseases: A Cross-sectional Study
This cross-sectional study aims to assess the level of awareness, knowledge, and preventive behaviors regarding air quality and air pollution among parents of children with physician-diagnosed allergic respiratory diseases (asthma and/or allergic rhinitis). The survey will evaluate parents' understanding of air pollution effects, sources, and protective measures, as well as sociodemographic and clinical correlates influencing awareness.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Air Quality Knowledge QuestionnaireBehavioural
A structured, self-administered questionnaire on air quality and pollution will be provided to all participants.
The survey consists of a total of 23 main items and an additional demographic information section.
The demographic section collects data on parent's age, gender, education level, occupation, and the child's age, gender, diagnosis (asthma and/or allergic rhinitis), and disease duration.
The main questionnaire includes:
- 5 items assessing knowledge of air pollution and air quality concepts;
- 10 items measuring awareness of air pollution sources, health impacts, and environmental conditions;
- 8 items evaluating attitudes and protective behaviors toward air pollution (e.g., monitoring air quality index, modifying outdoor activities, using indoor air filters).
Responses are based on a Likert-type scale. The tool is designed to quantify parental understanding, awareness, and preventive practices related to air quality in the context of childhood allergic airway diseases.

| Parents of Children with Allergic Airway Diseases | This cohort includes parents or primary caregivers of children aged 2-18 years who have been clinically diagnosed with allergic airway diseases (asthma and/or allergic rhinitis) by a pediatric allergy specialist. Participants will complete a structured questionnaire assessing their awareness, knowledge, and preventive behaviors regarding air pollution and air quality. Receives: Behavioral: Air Quality Knowledge Questionnaire |
What is being measured
The primary outcome is the main question the study is designed to answer.
Level of Parental Knowledge and Awareness About Air Quality
The primary outcome is the overall score obtained from the Air Quality Knowledge and Behavior Questionnaire, reflecting parents' knowledge and awareness regarding air quality and air pollution.
The composite score will be derived from the 5 knowledge and 10 awareness items, each rated on a Likert scale (e.g., 1 = strongly disagree to 5 = strongly agree).
Higher total scores indicate greater knowledge and awareness of air pollution, its sources, and its health effects.
Measured: At baseline (single survey administration)
