Frontal Systems Behavior Scale in schizophrenia: relationships with psychiatric symptomatology, cognition and adaptive function.

Schizophrenia patients often exhibit impairments in executive functioning on formal testing and exhibit behaviors consistent with executive/frontal impairment in daily life. The Frontal Systems Behavior Scale (FrSBe) assesses behaviors associated with frontal lobe damage including executive dysfunction, apathy and disinhibition. We examined the reliability and validity of the FrSBe in 131 schizophrenia outpatients.
