Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcome measures: a.Change in social cognitive deficit score: For self other differentiation- Signal detection theoretical analysis would be used evaluate the sensitivity in decision making using dee prime, criterion and JZS Bayes factor. Mean scores of ToM deficit variable (TDV) scores and HCP TOM tasks would be used for TOM and biological motion perception scores respectively Secondary outcome measures: Association between change in auditory hallucinations severity with change in social cognitive deficit score: Response to brain stimulation would be quantified as change in AHRS scores in two ways: â?¢As a continuous outcome- Pre-treatment score- Post-treatment score/ Pre-treatment score â?¢As a categorical outcome- Participants with 30% change in AHRS scores Timepoint: Time point 1: Baseline Time point 2: After 15 days of intervention | — |
