Outcome Measures

Primary Outcomes (1)

  • The Change in the Severity of Negative Symptoms

    The assessment of negative symptoms were measured with the Positive and Negative Symptom Scale (PANSS) and the Scale for the Assessment of Negative Symptoms (SANS).The SANS contains 30 particular items divided into 5 symptomatological domains: 1) affective flattening and/or blunting, 2) alogia, 3) avolition and/or apathy, 4) anhedonia, and 5) impaired attention. Each item is scored on a scale from 0 (not at all) to 5 (severe) with a total scoring range of 0 to 150. Higher scores indicate more impairment.The PANSS contains 30 particular items divided into 3 subscores: 1)positive, 2) negative, and 3) general subscore. Each item is scored on a scale from 1 (absent) to 7 (extreme) with a total scoring range of 30 to 210. Higher scores indicate more impairment. The primary outcomes were the changes in the severity of negative symptoms as measured with SANS total score and PANSS negative subscore after 4 weeks of intervention.

Study Arms (2)

Active rTMS

ACTIVE COMPARATOR

Active treatment will be delivered at an intensity that is 90% of the resting motor threshold (RMT). Stimulation will be delivered at 20 Hz with 100 stimulation trains of 20 stimuli each (i.e., 2000 stimuli) and an inter-train interval of 9 sec. Treatment will be applied in sequential order to the left dorsolateral prefrontal cortex (DLPFC). Intervention: Device: Repetitive Transcranial Magnetic Stimulation

Device: Repetitive Transcranial Magnetic Stimulation

Sham rTMS

SHAM COMPARATOR

Sham rTMS stimulation will be delivered using the same stimulation parameters and at the site of active treatment, but the coil will be reversed. This method produces sound and some somatic sensation (e.g., contraction of scalp muscles) similar to those of active stimulation, but with minimal direct brain effects.Intervention: Device: Repetitive Transcranial Magnetic Stimulation

Device: Repetitive Transcranial Magnetic Stimulation

Interventions

The MagPro X100 is connected to a Magnetic Coil which transfers the magnetic stimulation to the tissue. The original coils MC-B65 can be used with the MagPro X100.
