title: Personality-related core beliefs in patients diagnosed with fibromyalgia plus depression: A comparison with depressed and healthy control groups.
abstract: BACKGROUND
  Personality has an important role in understanding both fibromyalgia syndrome (FMS) and major depressive disorder (MDD).
  
  
  OBJECTIVE
  This study considers the question that specific personality features may characterize depressed FMS patients.
  
  
  METHODS
  To this end, 125 individuals were included in the study: 40 of them diagnosed with FMS+ MDD, 40 with MDD only and 45 healthy controls. Individual Beck Depression Inventory (BDI) and Personality Belief Questionnaire-Short Form (PBQ-SF) scores were compared between the three groups.
  
  
  RESULTS
  The mean scores for each personality domain of the PBQ-SF were the highest in the MDD group and the lowest mean scores appeared in the control group. Dependent personality and obsessive-compulsive personality scores were higher in the MDD group (t = 2.510, P = 0.014 and t = 2.240, P = 0.028, respectively) in comparison with the FM+ MDD group. However, this difference disappeared when PBQ-SF scores were controlled for depression severity.
  
  
  CONCLUSIONS
  Although some common personality features are evident in FMS patients, it seems that the differences identified are primarily related to depression symptom severity.
