Childhood trauma in Chronic Fatigue Syndrome: focus on personality disorders and psychopathology.
Sáez-Francàs, Naia, Calvo, Natalia, Alegre, José et al. · Comprehensive psychiatry · 2015 · DOI
Quick Summary
This study looked at whether ME/CFS patients who experienced childhood trauma are more likely to have personality disorders and mental health challenges like depression. Researchers surveyed 166 ME/CFS patients using questionnaires about their childhood experiences and current mental health. They found that about one-third had experienced childhood trauma, and nearly half had signs of a personality disorder. Importantly, emotional trauma (like neglect or abuse) was more strongly connected to personality disorders than physical trauma.
Why It Matters
Understanding how childhood trauma and personality factors contribute to ME/CFS psychopathology can improve clinical assessment and psychological support strategies for this population. This study provides evidence that emotional trauma history may be particularly relevant to mental health outcomes in ME/CFS, informing targeted intervention development and clinician awareness of psychological comorbidities.
Observed Findings
33.1% of ME/CFS patients reported childhood trauma; emotional neglect (21.7%) and emotional abuse (18.1%) were most common
47.6% of patients met criteria for at least one personality disorder
Emotional childhood trauma was significantly associated with personality disorder presence (OR=2.18, p=0.034), but physical trauma showed no significant difference
Trauma severity was related to higher number of PDs, more severe depressive symptoms (p=0.025), and elevated suicide risk (p=0.001)
Patients with both PD and childhood trauma history showed the most severe depressive, irritable symptoms and highest suicide risk
Inferred Conclusions
Emotional childhood trauma (rather than physical trauma) is specifically associated with higher frequency of personality disorder diagnosis in ME/CFS patients
Trauma severity is dose-dependently related to multiple domains of psychopathology including depression and suicide risk
Combined presence of personality disorders and childhood trauma history indicates a subgroup at particularly high risk for severe psychiatric symptoms
Remaining Questions
What is the temporal relationship between childhood trauma, personality disorder development, and ME/CFS onset?
What This Study Does Not Prove
This study cannot establish causality or temporal sequence—it does not prove that childhood trauma causes personality disorders or ME/CFS, only that they are associated. The cross-sectional design means we cannot determine whether trauma preceded CFS onset or whether other unmeasured factors explain the associations. Additionally, findings in this specific CFS cohort may not generalize to all ME/CFS populations.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
