Abstract:

Objective: This study explores the influencing factors of patients with poor cooperation in pulmonary function tests based on the Theory of Planned Behavior, aiming to provide a basis for constructing a pulmonary function test plan for such patients and improving the quality of pulmonary function tests. Methods: The phenomenological research method in qualitative research was adopted. Fifteen patients with poor cooperation in pulmonary function tests from June to August 2024 in Dali Prefecture People’s Hospital were selected as the research objects through purposive sampling. Semi-structured interviews were conducted, and the interview data was analyzed using Colaizzi’s seven-step analysis method. Results: Combining with the Theory of Planned Behavior, 3 themes were extracted, including behavioral attitude (negative emotions towards the disease, lack of attention to the disease, insufficient understanding of pulmonary function specialized examinations), subjective norms (medical support, influence of social roles, peer effect), and perceived behavioral control (discomfort during the examination, poor communication environment, need for examination guidance). Conclusion: On the basis of improving patients’ understanding of pulmonary function tests, reducing discomfort, and alleviating psychological pressure, providing personalized examination guidance according to patients’ needs is an important way to improve patient’s cooperation towards pulmonary function tests.
