The aim of this study was to investigate the effectiveness of cognitive-behavioral therapy in quality of life in schizophrenic   patients.
Materials and Methods: The population of this quasi-experimental study with the control group included all patients afflicted with chronic schizophrenia who were residual in Karaj care centers in 1394.Among these centers two were randomly selected. Then, among patients who met inclusion criteria, thirty were randomly selected and replaced in two groups; fifteen in experimental group and fifteen in control group. The experimental group received 8 sessions of cognitive-behavioral intervention but control group remained on the waiting list.
