Abstract:
OBJECTIVE: The process of somatization in chronic fatigue syndrome (CFS) was investigated using the concept of illusory mental health (IMH). IMH involves self-reporting low emotional distress alongside performance-based assessment of distress.
METHOD: We studied IHM and physical symptoms in 175 women across four groups: (a) CFS plus depression; (b) CFS with no depression (CFS-ND); (c) depressive disorder without CFS; and (d) healthy controls (HC). IMH was assessed using a self-report measure plus the performance-based Early Memory Index (EMI).
RESULTS: CFS-NDs were no more likely to have IMH compared with HCs. Among the CFS-NDs, IMH was associated with more physical symptoms. For CFS-NDs, EMI added meaningfully beyond self-reported mental health in predicting physical symptoms.
CONCLUSION: Findings refute reducing CFS to somatization, but there is a subgroup of CFS whose lacking access to emotional distress is associated with heightened physical symptomatology.
