Abstract
In schizophrenia, social cognitive impairment is considered one of the greatest obstacles to social participation. Although numerous measures have been developed to assess social cognition, only a limited number of them have become available in Japan. We are therefore planning this evaluation study for social cognition measures in Japan (ESCoM) to confirm their psychometric characteristics and to promote research focused on social cognition. Participants in the cross-sectional observational study will be 140 patients with schizophrenia recruited from three Japanese facilities and 70 healthy individuals. In our primary analysis, we will calculate several psychometric indicators with a focus on whether they can independently predict social functioning. In secondary analyses, we will assess the reliability and validity of the Japanese translations of each measure and conduct an exploratory investigation of patient background, psychiatric symptoms, defeatist performance belief, and gut microbiota as determinants of social cognition. The protocol for this study is registered in UMIN-CTR, unique ID UMIN000043777.

Schizophrenia is a severe mental disorder for which complete recovery is difficult to achieve by conventional therapies
Through voting and discussion by an expert panel and two observational studies, six measures from a pool of 108 candidates were recommended for assessing social cognitive impairment in schizophrenia and other mental disorders [5,6,7]
The present study aims to simultaneously assess measures of social cognition and quantitatively determine which measures are psychometrically superior
Summary
Schizophrenia is a severe mental disorder for which complete recovery is difficult to achieve by conventional therapies. Measures for assessing social cognitive impairment have been developed from various perspectives Many of these measures are based on original theories, and reliability and validity have not been sufficiently examined for some of them [5]. To address this problem, the Social Cognition Psychometric Evaluation (SCOPE) study was conducted in the United States from 2012 to 2017. Through voting and discussion by an expert panel and two observational studies, six measures from a pool of 108 candidates were recommended for assessing social cognitive impairment in schizophrenia and other mental disorders [5,6,7]. The results were based on data collected in only the United
