THE EFFECTIVENESS OF INTERNET COGNITIVE BEHAVIOURAL THERAPY FOR GENERALIZED ANXIETY DISORDER IN CLINICAL PRACTICE: Research Article: iCBT for GAD in General Practice

Abstract

BACKGROUND: Clinical trials have demonstrated the efficacy of internet cognitive behavioral therapy (iCBT) in the treatment of generalized anxiety disorder (GAD). The current study aims to determine whether these efficacy findings, established under controlled research conditions, translate into effectiveness in practice. METHODS: The sample comprised 588 patients who completed at least one iCBT lesson for GAD through CRUfAD clinic (www.crufadclinic.org). This six-lesson course became available to primary care physicians to prescribe in 2009. Routine data collection included demographics, GAD symptomatology (GAD-7), psychological distress (K-10), and disability (WHODAS). RESULTS: All six lessons were completed by 324/588 (55.1%) patients. When compared with completers, noncompleters tended to be younger and based in rural locations. Prior to discontinuing the course, noncompleters demonstrated statistically significant reductions in psychological distress. For those who completed the course, effect sizes on all outcome measures were medium to large and over 60% of moderate-to-severe GAD cases met criteria for remission upon treatment completion. CONCLUSIONS: The current study indicates that computerized CBT for GAD is effective in generating positive, clinically significant outcomes among typical patients treated under the usual conditions in primary care. Future research should focus on reducing treatment discontinuation among younger people and those based in rural locations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
