Summary:Mentalising impairment (an impaired ability to think about people in terms of their mental states) has frequently been associated with schizophrenia. To assess the magnitude of the deficit and analyse associated factors. Twenty-nine studies of mentalising in schizophrenia (combined n=1518), published between January 1993 and May 2006, were included to estimate overall effect size.
