Abstract
When sleep problems in adolescents ascent in severe disabling fatigue, which lasts for at least six months and is not alleviated by rest, they can be diagnosed with chronic fatigue syndrome (CFS).
FitNet is an online cognitive behavioral therapy for adolescents with CFS.
Because of the promising results on effectiveness in a randomized controlled trial, FitNet was implemented in routine clinical practice.
The goal of this thesis was to investigate the effectiveness of FitNet after implementation in routine clinical practice.
First, the effects of FitNet (N = 241, age 12-18) on Fatigue Severity, Physical Functioning and School Attendance was compared with the results of the previous randomized controlled trial by using a benchmark comparison.
Second, the effect of FitNet on Fatigue Severity, Physical Functioning and School Attendance was compared with Face-to-Face cognitive behavioral therapy (CBT) (N = 84, age 11-18).
FitNet was expected to have a greater decrease in CFS symptoms than Face-to-Face CBT
Third, it was investigated whether anxiety has a negative impact on the effectiveness of FitNet.
The benchmark comparison showed that the confidence interval of the percentage recovered patients in the present study overlapped with the interval of the randomized controlled trial.
These findings suggest that FitNet is equally effective after implementation in clinical routine practice as during the randomized controlled trial.
The comparison with the Face-to-Face CBT found that, on average, participants showed a significant decrease in all three CFS symptoms, but there was no difference between the Faceto-Face group or the FitNet group.
Furthermore, anxiety did not negatively influence the effects of FitNet.
Together, these findings suggest that FitNet is an effective treatment for reducing symptoms in CFS patients.
