I have no personal knowledge about this study, it is far out of my area. If anyone contacts them please comment if it's still ongoing.
Supposed to pay $350 to participants, who will receive both rTMS and placebo (but won't know when they get which)
"Persons travel from all over the US to enroll in our TMS trial for voices. Reasonable transportation costs are covered by grant funding. Participants need to be 18-55 years old, have a diagnosis of schizophrenia, schizoaffective disorder, or affective disorder (depression or bipolar disorder), and experience "voices" at least 3-4 times per day. Individuals with a history of seizures or serious medical conditions may not participate in the study. Participants also cannot abuse drugs or alcohol for at least 30 days prior to study enrollment and during the study itself, and will need to stay on a steady dose of psychiatric medication for that period of time also. We do not require participants to be on psychiatric medication in order to enroll on the study, however. A prior history of drug or alcohol problems does not exclude people from enrolling in the study. "
