Asthma, a chronic inflammatory condition affecting the airways, significantly impacts both respiratory function and quality of life. Recent studies have highlighted the psychological dimensions of chronic diseases like asthma. Despite growing evidence linking asthma with various psychopathological conditions, comprehensive data remains scarce. This study aims to explore the psychopathological status of asthma patients and identify demographic and clinical factors associated with higher levels of psychopathological symptoms. Data were collected from 42 asthma patients attending the Asthma Outpatient Clinic at the University of Thessaly, Greece. Participants completed a detailed questionnaire on demographics and clinical parameters, along with the Symptoms Checklist-90 (SCL-90) to assess psychological symptoms. The sample included patients with varying asthma severity: 38% with severe asthma and 62% with mild-moderate asthma, with a mean age of 60.8 ± 15.6 years. Results indicated that 23.8% exhibited somatization symptoms, 23.8% showed compulsive behaviors, 33.8% reported interpersonal sensitivity, and 38.1% experienced depression and 38.1% aggressiveness. Additionally, 45.2% struggled with fearful anxiety, 4.8% showed paranoid ideation, and 11.9% had traits of psychoticism. Women had significantly higher psychopathology scores than men. Factors such as longer disease duration, uncontrolled asthma, severe asthma, and comorbid conditions like atopy and gastroesophageal reflux disease (GERD) were linked to higher psychopathological scores. The study found a high prevalence of psychopathological symptoms among asthma patients. Female gender, prolonged asthma duration, persistent symptoms, comorbid diseases (GERD, atopy) and greater disease severity were significantly associated with higher psychopathology, underscoring the need for integrated mental health care in asthma management.
