False Safety Behavior Elimination Therapy: A Randomized Study of a Brief Individual Transdiagnostic Treatment for Anxiety Disorders

Study Overview
=================
Brief Summary
-----------------
The aim of the current study was to test the efficacy of an individually administered, brief (5-session) transdiagnostic treatment for anxiety disorders. The current treatment (called F-SET) focuses chiefly on the elimination of anxiety maintaining behaviors and cognitive strategies (so-called safety aids) among individuals suffering from a range of anxiety disorders including generalized anxiety disorder (GAD), social anxiety disorder (SAD) and panic disorder (PD). We hypothesized that the F-SET protocol would produce better overall outcome relative to a waitlist control.

Detailed Description
-----------------
The aim of the current study was to test the efficacy of an individually administered, brief (5-session) transdiagnostic treatment for anxiety disorders. The current treatment (called F-SET) focuses chiefly on the elimination of anxiety maintaining behaviors and cognitive strategies (so-called safety aids) among individuals suffering from a range of anxiety disorders including generalized anxiety disorder (GAD), social anxiety disorder (SAD) and panic disorder (PD). Four primary hypotheses were evaluated in the current study: (1) the F-SET protocol would produce better overall outcome relative to a waitlist control, (2) the F-SET protocol would yield clinically significant improvement of primary diagnosis symptoms as well as secondary diagnosis symptoms, (3) the F-SET protocol would create treatment improvement that is maintained during a 1 month follow-up interval and (4) given that reduction of safety aid use is the key mechanism of change in the F-SET treatment, a reduction in safety aid use will mediate the relationship between pre and post treatment.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Transdiagnostic Treatment (F-SET)<br>F-SET treatment consisted of five weekly individual sessions (approximately 50 minutes each). The F-SET protocol is consistent with current CBT protocols for anxiety disorders. | Behavioral: Transdiagnostic Treatment (F-SET)<br>* F-SET treatment consisted of five weekly individual sessions (approximately 50 minutes each). The participants learn to techniques and skills to help them reduce their anxiety. F-SET protocol is consistent with current CBT protocols for anxiety disorders.<br>|
| No Intervention: Waitlist<br>The waitlist control condition was comprised of patients randomly assigned to the waitlist condition (WL). Individuals in this condition were reassessed after five weeks and were then offered treatment, but were no longer followed. | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Structured Clinical Interview for the DSM-IV | Structured Clinical Interview for the DSM-IV (SCID-IV). The SCID-IV (Spitzer, Gibbon, & Williams, 1996) is a structured diagnostic interview designed to provide detailed coverage of Axis-I disorders. The SCID-IV has been shown to be a reliable and valid measure of the Diagnostic and Statistical Manual of Mental Disorders (fourth edition-text revision; American Psychiatric Association, 2000) Axis I disorders (Zanarini et al., 2000). | One Month Follow-up | 
| Clinician Global Impressions Scale (CGI) - Severity of Illness Subscale | Clinician Global Impressions Scale (CGI) - Severity of Illness Subscale. The CGI (Guy, 1976) is a widely used clinician-rated measure of global impressions. The severity of illness subscale from the CGI is composed of a 7-point scale (ranging from 0=not at all ill to 6=among the most extremely ill patients) and is used to assess | One Month Follow-up | 
| Work and Social Adjustment Scale (WSAS) | Work and Social Adjustment Scale (WSAS). The WSAS is a 5-item descriptive measure of subjective interference in various life domains (i.e., work, home management, private leisure, and family relationships). Interference in the past week is rated from 0 (not at all interfering) to 8 (severe interference). The WSAS has demonstrated good internal consistency and has been successfully used in previous studies (e.g., Brown & Barlow, 1995; Ellard, Fairholme, Boisseau, Farchione, & Barlow, 2010). The WSAS was used as an index of overall disability and impairment. The WSAS demonstrated good internal consistency in the present sample (mean inter-item correlation = .28). | One Month Follow-up |
