Internet-based therapy for adolescents with chronic fatigue syndrome: long-term follow-up.
Nijhof, Sanne L, Priesterbach, Loudy P, Uiterwaal, Cuno S P M et al. · Pediatrics · 2013 · DOI
Quick Summary
This study followed adolescents with ME/CFS for nearly 3 years after they completed an internet-based cognitive behavioral therapy program called FITNET. About 59% of teenagers had recovered from their illness by the end of the follow-up period, and most of those who improved right after treatment stayed better. Interestingly, teens who received standard care also recovered at similar rates over time, though it took longer.
Why It Matters
This study provides important evidence that internet-based CBT can produce lasting improvements in adolescent ME/CFS, offering an accessible alternative to face-to-face treatment when availability is limited. The finding that usual care eventually achieves similar recovery rates, albeit more slowly, adds nuance to treatment planning and suggests that time and other factors beyond structured intervention may facilitate recovery in some adolescents.
Observed Findings
58.9% of adolescents had recovered from CFS at mean 2.7-year follow-up
Recovery rate for FITNET group was 64% compared to 52.8% for usual care (not statistically different)
Most adolescents who recovered immediately after FITNET treatment remained recovered at long-term follow-up
Each additional month of pretreatment disease duration decreased odds of recovery by 4%
Each additional point on maternal focus on bodily symptoms decreased odds of recovery by 11%
Inferred Conclusions
Internet-based CBT produces sustained improvements in adolescent CFS that persist beyond 2 years.
Unusual care achieves comparable long-term recovery rates to structured internet-based therapy, although at a slower pace.
Longer illness duration before treatment and higher maternal bodily symptom focus are associated with lower recovery odds.
Internet-based CBT may be a practical alternative to face-to-face CBT when access is limited.
Remaining Questions
Why do usual care groups eventually achieve similar recovery rates, and what mechanisms drive recovery in these adolescents?
What This Study Does Not Prove
This study does not prove that FITNET is superior to usual care for long-term recovery, since both groups showed similar recovery rates at follow-up. It also does not establish causation for the predictors identified (disease duration, maternal focus on symptoms)—these may be markers of other underlying factors affecting recovery. The lack of a pure no-treatment control limits conclusions about the natural history of adolescent ME/CFS.

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 →
