Comparative study of anxiety, depression, somatization, functional disability, and illness attribution in adolescents with chronic fatigue or migraine.

Quick Summary
This study compared teenage girls and boys with chronic fatigue, migraine headaches, and healthy peers to understand their emotional health and how much school they missed. Teenagers with chronic fatigue that met official diagnostic criteria had higher rates of anxiety, depression, and physical complaints than the other groups, and missed far more school days. Interestingly, parents of teenagers with unexplained chronic fatigue were less likely to think psychological stress was contributing to their child's illness compared to parents of teenagers with migraines.
Why It Matters
This study provides evidence that ME/CFS in adolescents presents with distinct psychological and functional profiles compared to other chronic illnesses, which may help clinicians recognize and appropriately manage the condition. Understanding that higher anxiety and depression co-occur with ME/CFS—and that parents may underestimate psychological contributions—informs holistic treatment approaches and validates the serious functional impact of the illness.
Observed Findings
Adolescents with CDC-CFS had significantly higher anxiety, depression, and somatization scores than those with idiopathic chronic fatigue, migraine, or controls.
School absenteeism showed a hierarchical pattern: CDC-CFS (most days missed) > I-CFS > migraine > healthy controls.
Adolescents with migraine had higher anxiety than those with idiopathic chronic fatigue but lower anxiety than those with CDC-CFS.
Parents of adolescents with idiopathic chronic fatigue attributed illness to psychological or stress factors significantly less often than parents in the CDC-CFS or migraine groups.
56–70% of all study groups were female, with mean age 14.0 ± 2.0 years.
Inferred Conclusions
Adolescents meeting CDC criteria for chronic fatigue syndrome experience greater emotional distress (anxiety, depression) and functional impairment than those with unexplained chronic fatigue alone or other chronic conditions like migraine.
Parental illness attribution differs systematically between diagnostic groups, with parents of idiopathic chronic fatigue cases being less likely to recognize psychological contributions, which may influence help-seeking and treatment engagement.
The pattern of psychological symptoms and absenteeism suggests that CFS in adolescence has substantial psychosocial burden alongside its functional effects.
Remaining Questions
What This Study Does Not Prove
This cross-sectional design cannot establish causation: elevated anxiety and depression may result from living with a disabling illness rather than causing it, and the study does not track whether these symptoms persist or change over time. The study also does not evaluate post-exertional malaise, orthostatic intolerance, or immunological markers, so it does not address core ME/CFS physiological features. Additionally, differences in illness attribution between parent groups may reflect different illness models rather than objective differences in disease etiology.

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 →
Do elevated anxiety and depression in CDC-CFS represent primary features of the illness, secondary consequences of disability, or both?
Why do parents of I-CFS adolescents attribute illness less to psychological factors despite similar or slightly lower symptom scores—does this reflect different illness perceptions or unmeasured biological differences?
What is the longitudinal trajectory of anxiety, depression, and somatization in these adolescent cohorts, and do psychological symptoms predict recovery or outcome?
How do these psychological profiles relate to objective physiological measures (e.g., post-exertional malaise, immune markers, cardiac autonomic function) in ME/CFS versus migraine?
