The goal of this study is to evaluate the efficacy of Alpha-Stim technology in the treatment of anxiety by using a double-blind clinical trial over a period of five weeks. Cranial-electrotherapy stimulation (CES) is a noninvasive procedure that has been used for decades in the United States to treat anxiety, depression, and insomnia. Although many studies on CES have been published in previous decades, most have used relatively small samples using various frequencies and links of treatment. Given the positive results of the many general studies that have been performed to date, this study seeks to add to the current literature by addressing previous criticisms using a large sample size (n=150)and using participants that represent more than a single type of anxiety along with comorbidity. Such a population is believed to better represent typical treatment complications.
