title: The significance of personality in pain from gallbladder stones.
abstract: BACKGROUND
  The aim of the study was to investigate the association between personality factors related to coping styles and reported pain due to gallstones.
  
  
  METHODS
  Personality trait measures were completed by 28 consecutive gallstone patients to provide estimates of positive coping resources (Life Regard Index, Sense of Coherence Scale, Sense of Humor Questionnaire) and negative coping resources (Eysenck Personality Questionnaire on Neuroticism, Tension, and Effort Stress Inventory). An overall index of gallstone-related complaints (pain) over the past 7 days/6 months was also obtained. Ultrasonography confirmed the gallstone condition. Multiple regression analyses tested the hypothesis that pain would be moderated by positive coping resources and mediated by negative coping resources.
  
  
  RESULTS
  Reported pain was less severe with positive coping resources (39% of pain variance explained) and more severe with negative coping resources (45% of pain variance explained).
  
  
  CONCLUSIONS
  The results confirm that mental coping resources have a significant role in pain differences among gallstone patients.
