Outcomes
Primary Outcome Measures
Change in the Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) at Post-treatment and 3-month Follow-up.
Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) scores range from 0-56 with higher scores indicating more severe anxiety.
Responder Status
Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) scores range from 0-56 with higher scores indicating more severe anxiety. Responder status was defined as a ≥ 50% improvement (i.e., reduction) in SIGH-A scores from pre-treatment to post-treatment.
Remission Status
Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) scores range from 0-56 with higher scores indicating more severe anxiety. Remission status was defined as a SIGH-A score < 8 and Clinical Global Impression Improvement score = 1 ("very much improved") or 2 ("much improved") at post-treatment.
Responder Status
Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) scores range from 0-56 with higher scores indicating more severe anxiety. Responder status was defined as a ≥ 50% improvement (i.e., reduction) in SIGH-A scores from pre-treatment to 3-month follow-up.
Remission Status
Structured Interview Guide for the Hamilton Anxiety Rating Scale (SIGH-A) scores range from 0-56 with higher scores indicating more severe anxiety. Remission status was defined as a SIGH-A score < 8 and Clinical Global Impression Improvement score = 1 ("very much improved") or 2 ("much improved") at 3-month follow-up.

5. Study Description
Brief Summary
This study is investigating a new indication of Transcranial Magnetic Stimulation (TMS) by conducting a pilot randomized-controlled trial (RCT) comparing structural neuronavigation-directed TMS to Sham-TMS Placebo therapy for treatment of Generalized Anxiety Disorder (GAD).
Detailed Description
Participants will complete structural MRI for neuronavigation. Participants will be randomly assigned to treatment condition. TMS or Sham-TMS sessions will occur daily 5 days/week for 6 weeks. Assessments will occur at pretreatment, weekly during treatment, post-treatment, and 3 month.
