Introduction. Rorschach Perceptual and Thinking Index (PTI) has been proved effective in differentiating adolescents at clinical high risk for psychosis from non-psychotic patients, evaluated with the Structured Interview for Prodromal/Psychosis-risk Symptoms (SIPS). However, the relationships between SIPS and PTI criteria have not been explored. Objectives. The aims of this study were to investigate the relationships between the five PTI criteria, their main variables (X-%; WSum6; M-) and the SIPS subscales (Positive, Negative, Disorganization and General Symptoms). Methods. A sample of 117 help seeking adolescents, 68% females, aged 14-19 years, with anxiety, mood and bipolar spectrum disorders were included in the study. All were recruited at the first visit and evaluated with the Rorschach (according to the standard Comprehensive System Method) and the Structured Interview for Prodromal Symptoms (SIPS). Results. PTI Total score and PTI1 significantly correlated with SIPS negative, disorganization and general subscales (rs0,2–0,4; p<0.05); PTI2 with disorganization and general subscales (rs0,2–0,4; p<0.05); PTI3 with positive subscale (rs=0,22;p=0.02); PTI4 with positive, negative and disorganization subscales (rs0,2–0,4; p=0.02) and PTI5 with disorganization and general subscales (rs=0,2; p< 0.02). WSum6 significantly correlated with positive and disorganization subscales (rs=0,2–0,3; p<0.01); X- with disorganization and general subscales (rs0,2–0,3; p<0.02) and M- with disorganization subscale (rs=0,2; p=0.02). Conclusions. Rorschach PTI criteria and their main variables (X-%; WSum6; M-) show a mild to moderate correlation with specific SIPS subscales and might be helpful in identifying adolescents at risk for psychosis.

Abstract

Introduction. Rorschach Perceptual and Thinking Index (PTI) has been proved effective in differentiating adolescents at clinical high risk for psychosis from non-psychotic patients, evaluated with the Structured Interview for Prodromal/Psychosis-risk Symptoms (SIPS). However, the relationships between SIPS and PTI criteria have not been explored. Objectives. The aims of this study were to investigate the relationships between the five PTI criteria, their main variables (X-%; WSum6; M-) and the SIPS subscales (Positive, Negative, Disorganization and General Symptoms). Methods. A sample of 117 help seeking adolescents, 68% females, aged 14-19 years, with anxiety, mood and bipolar spectrum disorders were included in the study. All were recruited at the first visit and evaluated with the Rorschach (according to the standard Comprehensive System Method) and the Structured Interview for Prodromal Symptoms (SIPS). Results. PTI Total score and PTI1 significantly correlated with SIPS negative, disorganization and general subscales (rs0,2–0,4; p<0.05); PTI2 with disorganization and general subscales (rs0,2–0,4; p<0.05); PTI3 with positive subscale (rs=0,22;p=0.02); PTI4 with positive, negative and disorganization subscales (rs0,2–0,4; p=0.02) and PTI5 with disorganization and general subscales (rs=0,2; p< 0.02). WSum6 significantly correlated with positive and disorganization subscales (rs=0,2–0,3; p<0.01); X- with disorganization and general subscales (rs0,2–0,3; p<0.02) and M- with disorganization subscale (rs=0,2; p=0.02). Conclusions. Rorschach PTI criteria and their main variables (X-%; WSum6; M-) show a mild to moderate correlation with specific SIPS subscales and might be helpful in identifying adolescents at risk for psychosis.
