This study is double-blind, between group, and sham-controlled. Subjects will be randomized to one of three arms (tRNS, tDCS, or sham) and will remain in that arm for the duration of the study. All subjects will complete an enrollment visit, ten treatment visits (2 visits per day), and 1, 3, and 6 month follow-up visits. Given that durability of effect has been suggested in the literature to be less than 6 months, patients will not be followed beyond 6 months. The outcome of this study will be measured by standard auditory hallucination rating scales including the Positive and Negative Symptoms Scale (PANSS), Auditory Hallucinations Rating Scale (AHRS), and psychotic symptom rating scales (PSYRATS). Both the AHRS and PSYRATS are included as outcome measures to ensure generalizability to existing studies on tES (which use the AHRS) along with the broader body of AH research (which use the PSYRATS). The primary efficacy parameter will be the PSYRATS as this has shown the most evidence for accurate representation of AH.
