Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in severity of negative symptoms before and after TMS intervention, i.e., change in Positive and Negative Syndrome Scale - Negative subscale (PANSS-N)
Lasso di tempo: Negative symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
Schizophrenia negative symptoms assessed using Positive and Negative Syndrome Scale - Negative subscale (PANSS-N) Minimum value: 7 (each of the 7 items scored 1 = absent) Maximum value: 49 (each of the 7 items scored 7 = extreme) Higher score indicates: Worse outcome (greater severity of negative symptoms) |
Negative symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.

|
Change in cognitive function scores before and after intervention
Lasso di tempo: MATRICS Consensus Cognitive Battery (MCCB) will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and 4 weeks ( Day 42) after completion of TMS treatment.
|
MATRICS Consensus Cognitive Battery (MCCB) total score and subtest scores
|
MATRICS Consensus Cognitive Battery (MCCB) will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and 4 weeks ( Day 42) after completion of TMS treatment.
|
|
Change in positive symptom scores before and after intervention
Lasso di tempo: Positive symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
Positive and Negative Syndrome Scale - Positive subscale (PANSS-P) Minimum value: 7 (each of the 7 items scored 1 = absent) Maximum value: 49 (each of the 7 items scored 7 = extreme) Higher score indicates: Worse outcome (greater severity of positive symptoms) |
Positive symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
|
Change in general symptom scores before and after intervention
Lasso di tempo: General symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
Global Assessment of Functioning (GAF) score.
The score ranges from 0 to 100 points.
Higher scores indicate better levels of functioning.
|
General symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
|
Change in anxiety symptoms before and after intervention
Lasso di tempo: Anxiety symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
Anxiety symptoms measured using Hamilton Anxiety Rating Scale (HAMA).
Each item scored 0 (not present) to 4 (severe), total score range 0-56.
Higher scores indicate more severe symptoms.
|
Anxiety symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
|
Depressive symptoms changes
Lasso di tempo: Depressive symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
Depressive symptoms measured using Hamilton Depression Rating Scale (HAMD).
Measure of depression severity - total score ranges from 0 (no depression) to 76 (most severe depression)
|
Depressive symptoms will be measured at baseline (Day-4±2), immediately after the 50th session of TMS (Day 14), and at 2 weeks (Day 28), and 4 weeks ( Day 42) after completion of TMS treatment.
|
|
Safety as measured by number of participants with Adverse Events
Lasso di tempo: Record the adverse events reported on that day after completing the day's TMS treatment. This should be done every day during the treatment period (Day 0 - Day 14)
|
Number of Adverse Events reported during TMS treatment
|
Record the adverse events reported on that day after completing the day's TMS treatment. This should be done every day during the treatment period (Day 0 - Day 14)
|
|
Resting-state functional MRI (rsfMRI) scan
Lasso di tempo: Resting-state functional MRI will be measured at baseline (Day-4±2), and immediately after the 50th session of TMS (Day 14).
|
Functional MRI scan will be conducted before and after treatment to assess treatment-induced changes in brain connectivity
|
Resting-state functional MRI will be measured at baseline (Day-4±2), and immediately after the 50th session of TMS (Day 14).
