Aims and objectives: This study aims to identify the effects of type D personality on symptom control and quality of life and to explore factors influencing quality of life among asthma patients in Korea. Background: Psychological factors such as depression and stress are well known to be related to medical outcomes and quality of life in asthma patients. People with type D personality are vulnerable to stress, show poor prognosis in disease and experience low quality of life. Design: A descriptive cross-sectional design was used. Methods: A total of 144 patients with asthma participated in this study. Data were collected through face-to-face interviews using structured questionnaires: the Type D Personality Scale-14, Asthma Control Test and Asthma-Specific Quality of Life. Results: About 33% of participants were classified into the type D personality group. The type D personality group showed statistically significantly lower symptom control and asthma-specific quality of life compared to the non-type D personality group. Based on forward stepwise multiple regression, the most significant factor of quality of life was symptom control, followed by type D personality, hospitalisation within the previous one year, and lifetime hospitalisation experiences. Conclusions: The prevalence of type D personality in asthma patients was high, and type D personality was significantly associated with poor symptom control and low quality of life. Psychosocial interventions might be beneficial to improve symptom control and quality of life in asthma patients with type D personality. Relevance to clinical practice: Nurses should be aware of the high prevalence of type D personality and the effects on symptom control and quality of life in asthma patients. Nurses should also provide personality-specific interventions to improve quality of life in such patients.
