PURPOSE: To assess chronic obstructive pulmonary disorder (COPD) patients' defensive profile compared with healthy participants and to test whether specific ego defense mechanisms are associated with health-related quality of life (HRQoL) and self-reported dyspnoea severity. METHODS: In a cross-sectional study, we assessed, in 80 patients with COPD and 80 age- and gender-matched healthy participants, psychological distress (Hospital Anxiety and Depression Scale) and defense mechanisms/styles (Defense Style Questionnaire). Patients had their HRQoL evaluated with the St. George's Respiratory Questionnaire and underwent a comprehensive clinical evaluation with determination of functional parameters and dyspnoea severity. RESULTS: COPD patients presented higher scores in undoing, acting out, autistic fantasy, denial, and splitting defenses compared with healthy controls. Overall, patients showed a more immature (P = 0.001) and/or neurotic (P = 0.006) defensive profile. Higher scores of denial (P = 0.044), somatization (P = 0.009), and undoing (P = 0.032) defenses were associated with poorer HRQoL, independently of the anticipated significant associations of clinical and psychological distress variables with impaired HRQoL. Somatization was strongly independently associated with more severe self-reported dyspnoea. CONCLUSIONS: COPD patients exhibit a relatively immature and neurotic defensive profile. Clinicians and consultation-liaison psychiatrists should consider the patients' underlying personality structure, especially somatization tendencies, since it is independently associated with HRQoL and dyspnoea severity.
