Development and validation of the Disease Knowledge Questionnaire for Allergic Rhinitis
This study developed and validated a reliable and valid 22-item Disease Knowledge Questionnaire for Allergic Rhinitis, based on the Common-Sense Model of Self-Regulation, to effectively assess patients' disease knowledge, prevention beliefs, and behavioral intentions.

Allergic rhinitis is a common, chronic condition that affects millions of people, causing a runny nose, sneezing, and itchy eyes. While the physical symptoms are well known, the way a person understands their own illness plays a massive role in how well they manage it. If a patient does not grasp what triggers their condition, how long treatments take to work, or how to prevent flare-ups, they are less likely to follow medical advice or feel in control of their health. This gap between having a diagnosis and truly understanding the disease is a major hurdle in modern healthcare. To bridge this gap, researchers need a reliable way to measure exactly what a patient knows and believes. Without a clear picture of a patient's knowledge, doctors cannot tailor their education to fill the specific holes in understanding.
A team of researchers at Renmin Hospital of Wuhan University set out to build such a tool. They created a new questionnaire designed specifically to test how much patients with allergic rhinitis know about their condition. The study was grounded in a psychological framework called the Common-Sense Model of Self-Regulation. This model suggests that when people face a health threat, they build a mental picture of the illness based on their own experiences and the information they have gathered. This mental picture includes ideas about what caused the sickness, how long it will last, how serious it is, and whether it can be controlled. The researchers used this idea to structure their questions, ensuring they covered the full range of a patient's understanding, from the causes of the allergy to the methods used to prevent it.
The process of creating this questionnaire was rigorous and involved several stages of refinement. The team started by reviewing existing medical literature and conducting interviews with doctors to gather a wide list of potential questions. They then consulted with a group of nineteen experts from various fields, including ear, nose, and throat specialists and nursing educators. These experts reviewed the questions, suggesting changes to make the language clearer and more accurate. Through this process, the initial list of questions was trimmed and polished. The final version of the questionnaire contains twenty-two questions divided into four main areas: the causes and symptoms of the disease, the impact the disease has on a person's life, the available treatments, and methods for prevention.
To test whether this new tool actually worked, the researchers distributed it to 392 patients with allergic rhinitis who visited a hospital in Wuhan. They asked the patients to answer the questions and then analyzed the results to see if the test was consistent and accurate. The analysis showed that the questionnaire was highly reliable. When the researchers checked if the questions within each section were consistent with one another, the results were very strong. They also used statistical methods to confirm that the four sections of the test were measuring distinct but related ideas, just as the researchers had intended. The data revealed that the tool successfully captured the different layers of a patient's knowledge, from knowing that pollen can trigger an attack to understanding that specific therapies can change the course of the disease.
The findings from this study offer a practical way for healthcare providers to assess their patients. The researchers found that the questionnaire could clearly identify which patients had a strong understanding of their condition and which ones were missing key information. For instance, the study highlighted that many patients were unsure about the duration of immunotherapy or did not realize that the disease could be well-controlled with treatment. By using this tool, doctors can now pinpoint these specific knowledge gaps. Instead of giving general advice, they can focus their education on the exact areas where a patient is confused. This approach allows for more personalized care, helping patients move from simply reacting to symptoms to actively managing their health with confidence.
While the study was conducted at a single hospital, the results suggest that this new questionnaire is a solid and effective instrument for measuring disease knowledge. It provides a standardized way to look at what patients know and believe, which is a crucial first step in improving how allergic rhinitis is managed. The researchers conclude that this tool can help design better health education programs, ultimately leading to better outcomes for people living with this chronic condition. By understanding the patient's mind, doctors can better support the patient's body.
