title: Personality dimensions and type D personality in female patients with ulcerative colitis.
abstract: OBJECTIVE
  Psychological factors such as personality traits may affect the adjustment capacity and Quality of Life (QOL) in Ulcerative Colitis (UC) patients. Type D personality has some similarities with general personality traits of UC patients. The aims of this study were to compare NEO personality profile and type D personality between healthy normal group and UC patients; and to determine the possible relationship between type D personality and QOL in UC patients.
  
  
  METHODS
  The sample of study comprised of 58 UC patients and 59 healthy control subjects (from their family members). All participants were requested to fill out NEO-FFI, Type D personality (Ds14) Scale and WHO-Quality of Life Questionnaire.
  
  
  RESULTS
  The findings indicated that UC patients scored higher in neuroticism (P<0/01); lower in extraversion (P<0/01) and openness (P<0/05) than healthy controls but their differentiation were not significant in agreeableness and conscientiousness. The findings showed that 59% of UC patients and 33% of the control subjects had type D personality; and the differences in frequency of type D between the two groups were significant (P<0/05). The mean QOL scores of type D personality in UC patients was significantly lower than patients without type D personality (F= 7/55, P<0/01). Type D personality could better predict QOL of UC patients than NEO dimensions.
  
  
  CONCLUSIONS
  Differences were observed between UC patients and their healthy family members, in terms of personality factors. Type D personality may be regarded as an important factor that may bring about some adverse effects in QOL among UC patients.
