Abstract
Background It is not yet clear whether chronic fatigue syndrome (CFS) is associated with elevated levels of personality disorders. Purpose This study aims to determine the prevalence of DSM-IV axis II personality disorders among patients with CFS. Methods We examined the prevalence of personality disorders in a sample of 92 female CFS patients and in two well-matched control groups, i.e., normal community individuals (N = 92) and psychiatric patients (N = 92). Participants completed the assessment of DSM-IV personality disorders questionnaire (ADP-IV), which yields a categorical and dimensional evaluation of personality disorder features. Results The prevalence of personality disorders in CFS patients (16.3 %) was significantly lower than in psychiatric patients (58.7 %) and was similar to that in the community sample (16.3 %). Similar results were found for dimensional and pseudodimensional scores, except for the Depressive (DE) and ObsessiveCompulsive Personality Disorder (O-C) subscales. Patients with CFS had significantly higher levels of DE features compared to normal controls and similar dimensional scores on the O-C scale compared to psychiatric controls. Conclusions Although the CFS sample was characterized by depressive and obsessivecompulsive personality features, this study provides no evidence for the assumption that these patients generally show a higher prevalence of axis II pathology. Given the conflicting findings in this area, future studies using multiple measures to assess personality disorders in CFS are needed to substantiate these findings.
