A second objective of this study is to test a new method to measure social cognition. Recent research showed that interview and performance based tests are poorly associated with every day activity of people with schizophrenia. This study is planning to evaluate the feasibility of new assessment methods for social cognition in everyday life using portable electronic devices (Experience Sampling Method and an activity watch). These devices will be carried by participants in their everyday life and will ask about feelings and levels of social activities at random times and record basic physiological and activity levels.
