Study summary

This study is examining the impact of a therapy group for all anxiety disorders provided by the Stanford Department of Psychiatry and Behavioral Sciences's Psychosocial Treatment Clinic on anxiety symptoms, impairment, and access to quality mental health care.

Read the detailed description

Anxiety disorders are prevalent, impairing, and often precede other psychiatric and medical comorbidity (Kessler et al, 2005). Cognitive Behavior Therapy (CBT) and Acceptance and Commitment Therapy (ACT) are effective, evidence-based treatments for anxiety disorders that can be delivered in either a group or individual format (Deacon \& Abramowitz, 2004; Arch et al 2012). Traditionally, group therapy has been delivered a single diagnosis at a time. This presents challenges to care delivery, however, because a sufficient number of patients with the same diagnosis and the same availability in their schedule must be assembled in order to start a group. Fortunately, CBT and ACT can be used to target key trans-diagnostic constructs such as excessive worry, avoidance, and fear of negative evaluation that may occur in many anxiety diagnoses. Indeed, emerging research suggests these constructs may be closer to the etiological dysfunction in anxiety disorders than the diagnoses themselves and may therefore be the best treatment targets (Craske, 2012). Because of this, there is now movement towards trans-diagnostic approaches that flexibly apply core principles of CBT and ACT to any anxiety disorder.

Group therapy is a cost-efficient and effective care delivery model that is also generally acceptable to patients with anxiety disorders. However, individual therapy is often preferred (Sharp et al, 2004), perhaps due to greater personalization of care relative to standard group therapy. To address this concern the investigators aim to use a pre-treatment assessment to develop a personalized plan for each patient entering a trans-diagnostic anxiety group.

In order to evaluate the effectiveness of this approach, patients enrolled in the group who consent to participate in research will complete assessments of anxiety and related symptoms, quality of life, and cognitive function before and after therapy.

Study population

The research study will be offered to all patients enrolling in a trans-diagnostic anxiety therapy group in the Stanford Department of Psychiatry \& Behavioral Sciences. The purpose of this study is to evaluate the effect of this therapy group, so participants will be limited to those enrolling in the group as part of their clinical treatment.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 18+
  • Enrolled in a trans-diagnostic group therapy for anxiety disorders in the Stanford Psychiatry \& Behavioral Sciences' Psychosocial Treatment Clinic.
  • English fluency

Exclusion criteria

Exclusion Criteria:

  • Unable to provide
  • Acute safety concerns (e.g., suicidality requiring a higher level of care)
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Group Therapy

    Patients in the Stanford Department of Psychiatry and Behavioral Sciences who are enrolling in a trans-diagnostic anxiety therapy group will be invited to participate in research on group processes and outcomes.

What researchers measure

Primary outcomes

  1. Overall Anxiety Severity and Impairment Scale [OASIS]

    Measures overall anxiety severity and anxiety-related impairment due to any anxiety disorder. Total scores are computed by summing scores from all 5 items. Total score ranges from 0 to 20, with higher scores indicating higher severity and impairment of anxiety symptoms. Reduction in OASIS scores therefore indicates better outcome.

    Time frame: 12 weeks

Secondary outcomes

  1. Sheehan Disability Scale [SDS]

    Measures disability. Total scores are computed by summing scores from all 3 items. Total score ranges from 0 to 30, with higher scores indicating greater disability. Reduction in SDS scores therefore indicates better outcome.

    Time frame: 12 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Aug 2019, 18 months.

Of 411 non-industry observational studies under Anxiety Disorders, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 49. This study's 18 months is close to that.

Counting every sponsor, half of 439 studies reached it within 19 months; a quarter within 6 and three quarters within 48.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 25, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
