title: Association between anger and first-onset primary spontaneous pneumothorax.
abstract: OBJECTIVE
  Primary spontaneous pneumothorax (PSP) is a frequent and problematic disease, but its underlying causes and pathophysiology remain unclear. This study examined whether anger, which is related to many psychosomatic diseases, is a psychosocial factor associated with first-onset PSP.
  
  
  METHODS
  We administered the State-Trait Anger Expression Inventory, Stress Response Inventory, Coping Scale, Beck Depression Inventory and Global Assessment of Recent Stress to 91 patients with first-onset PSP and to 77 patients with recent minor trauma as controls.
  
  
  RESULTS
  The scores on anger-in, anger-out, state anger and trait anger were significantly higher in the PSP group than in the control group. Logistic regression analysis revealed that low body mass index and trait anger could be associated with PSP.
  
  
  CONCLUSIONS
  We hypothesize that anger could play a role in the pathophysiology of PSP.
