Objective: The concepts of functionality and remission in schizophrenia are being subject for a substantial amount of research. At the same time, an increasing number of scales are developed in our country and worldwide, which are intended to measure the level of functionality in severe mental disorders. Functional remission is an important goal of treatment, which provides possibility of an autonomous lifestyle for schizophrenia patients, allowing them to readapt to their relationships with parents, work life, other interpersonal communications and social environments. The "Functional Remission of General Schizophrenia" (FROGS) Scale was developed in French and is suitable for use in research as well as for clinical evaluation of patients. We intended to carry out a validity and reliability study on this scale in order to make it eligible for use in the conditions within Turkey.
