TRANSDIAGNOSTIC VERSUS DIAGNOSIS-SPECIFIC CBT FOR ANXIETY DISORDERS: A PRELIMINARY RANDOMIZED CONTROLLED NONINFERIORITY TRIAL: Research Article: Transdiagnostic versus Diagnosis-Specific CBT

Open access

Abstract

BACKGROUND: Transdiagnostic cognitive-behavioral treatments for anxiety disorders have been gaining increased attention and empirical study in recent years. Despite this, research on transdiagnostic anxiety treatments has, to date, relied on open trials, or comparisons to waitlist conditions, published benchmarks, or relaxation-based interventions. METHODS: The current study was a randomized clinical trial examining the efficacy of a 12-week transdiagnostic cognitive-behavioral group treatment in comparison to 12-week diagnosis-specific group Cognitive-Behavioral Therapy (CBT) protocols for panic disorder, social anxiety disorder, and generalized anxiety disorder. RESULTS: Results from 46 treatment initiators suggested significant improvement during treatment, strong evidence for treatment equivalence across transdiagnostic and diagnosis-specific CBT conditions, and no differences in treatment credibility. CONCLUSIONS: This study provides evidence supporting the efficacy of transdiagnostic CBT by comparison to current gold-standard diagnosis-specific CBT for social anxiety disorder, generalized anxiety disorder, and panic disorder. Transdiagnostic group CBT has the benefit of potentially easing dissemination and increasing access to evidence-based treatments for anxiety without sacrificing efficacy.

  • Norton (2012) found lower drop-out rates during group TD-CBT, but no significant differences in anxiety severity at post-treatment compared to relaxation training.

    “although Norton (2012) found lower drop-out rates during group TD-CBT, there were no significant differences in anxiety severity at post-treatment compared to relaxation training.”

    From Systematic review and meta-analysis of transdiagnostic psychological treatments for anxiety and depressive disorders in adulthood (2015) · cites this paper as Norton (2012)

    The paper’s background discussion reports that an earlier Norton trial found greater dropout with relaxation training than with transdiagnostic group CBT, alongside statistically equivalent outcomes. However, the cited 2012 paper’s own trial compared transdiagnostic CBT with diagnosis-specific CBT, not relaxation training; the passage also does not specify a post-treatment anxiety-severity comparison. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Norton and Barrera (2012) found no significant differences between group-based TD-CBT and disorder-specific group CBT for anxiety disorders.

    “In contrast, in another RCT, Norton and Barrera (2012) found no significant differences between group-based TD-CBT and disorder-specific group CBT for anxiety disorders.”

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.
