One of the widely used psycho-diagnostic tests is the Rorschach Inkblot Test (RIBT).
The studies on Perceptual Thinking Index (PTI) from the RIBT protocol, developed to diagnose schizophrenia, have been conducted in many countries but, there is dearth of studies in Indian context. Forty-five subjects, 15 each in schizophrenia, Anxiety Spectrum Disorders (ASD) and Normal Control (NC) group were randomly assessed with socio-demographic data sheet, Positive and Negative Syndrome Scale (PANSS), Hamilton Anxiety Rating Scale (HAM-A) and Rorschach Test. Statistical analyses including effect size (ES) estimation revealed that variables of PTI have differentiated schizophrenia from ASD and normal group. Medium to large ES of five out of seven variables between the groups have also revealed effectiveness of the index.
