NCT02382224

Brief Summary

The purpose of this study is to examine the efficacy of a worry exposure intervention, a form of cognitive behavioral therapy (CBT), in comparison to a waitlist condition for the treatment of Generalized Anxiety Disorder. There will be a total of 60 subjects enrolled at the University of Texas at Austin. Patients will be randomized (like a flip of a coin) to either 12-sessions of WE therapy or a 12-week waitlist before being offered entry into therapy.

Outcome Measures

Primary Outcomes (1)

  • Change in Penn State Worry Questionnaire (PSWQ).

    The PSWQ will be administered 6 separate occasions. The investigators will measure the change in PSWQ scores from pre-treatment to weeks 3, 6, 9, 12, and 38. The PSWQ is a 16-item inventory designed to capture the generality, excessiveness, and uncontrollability of pathological worry. It has been shown to have good internal consistency with samples consisting of older adults with GAD, community subjects, and undergraduates. It has also demonstrated good test-retest reliability over 8-10 weeks.

    Up to 6 months

Secondary Outcomes (1)

  • Beck Anxiety Inventory (BAI).

    Up to 6 months

Study Arms (2)

Worry Exposure for GAD

EXPERIMENTAL

WE is an optimized protocol that incorporates elements of CBT, without the addition of other miscellaneous methods of treatment. A therapist manual will be used and followed at all times to ensure standardized delivery of the program. Interventions that uniquely focus on addressing GAD symptoms will include confronting physical or imagined stimuli through in vivo exposure and WE respectively. Avoidance behaviors will be monitored and reduced systematically, an outcomes will be assessed at baseline, during the 12-week intervention, and at 6-month follow-up.

Behavioral: Worry Exposure for GAD

12-week Waitlist

PLACEBO COMPARATOR

Those who are randomized to the waitlist condition will wait for 12 weeks before beginning the worry exposure.
