Outcome Measures

Primary Outcomes (1)

  • Clinical Severity Rating (CSR): change over time

    Diagnoses are assigned a dimensional clinical severity rating on a scale from 0 (no symptoms) to 8 (extremely severe symptoms), with a rating of 4 or higher representing the clinical threshold for diagnostic criteria. Observer-assessed.

    Baseline, post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1-year follow-up.

Secondary Outcomes (16)

  • Overall Anxiety Severity and Impairment Scale (OASIS): change over time

    Baseline, weekly during treatment (through up to 18 weeks/sessions) post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1-year follow-up

  • Overall Depression Severity and Impairment Scale (ODSIS): change over time

    Baseline, weekly during treatment (through up to 18 weeks/sessions) post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1-year follow-up

  • Generalized Anxiety Disorder-7 (GAD-7): change over time

    Baseline, post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1-year follow-up

  • Patient Health Questionnaire-9 (PHQ-9): change over time

    Baseline, post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1-year follow-up

  • Posttraumatic Stress Disorder Checklist-5 (PCL-5): change over time

    Baseline, post-treatment (immediately after treatment completion of up to 18 weeks/sessions), 1 year follow-up

  • +11 more secondary outcomes

Study Arms (2)

Metacognitive therapy (MCT)

EXPERIMENTAL

Transdiagnostic MCT, focused on modifying dysfunctional metacognitions and thereby reducing attentional and cognitive processes central to maintaining anxiety disorders.

Behavioral: Metacognitive therapy (MCT)

Unified protocol (UP)

ACTIVE COMPARATOR

Transdiagnostic cognitive-behavioral therapy, focused on emotion regulation processes central to the development and maintenance of anxiety disorders, particularly neuroticism.

Behavioral: Unified protocol (UP)

Interventions

MCT is delivered in weekly face-to-face sessions

Metacognitive therapy (MCT)

UP is delivered in weekly face-to-face sessions
