N2 - This secondary report from our 52-week, double-blind, relapse prevention trial tested whether stable patients with schizophrenia who were taken off active drug treatment would experience greater improvements in long-term quality of life than those who were continued on antipsychotic treatment. On average, Heinrichs-Carpenter Quality-of-Life Scale total scores improved by 4.3 +/- 10.6 points during treatment with olanzapine (10-20 mg/d; n = 212), but decreased by 7.1 +/- 14.6 points during treatment with placebo (n = 92; P <0.001). Mean Quality-of-Life Scale total scores worsened in both treatment groups for the relapsing patient subgroup, whereas for nonrelapsing patients, those treated with olanzapine had significantly improved mean Quality-of-Life Scale total scores compared with those given placebo. For a subset of nonrelapsing patients who were considered "nonexacerbating" on the basis of minimal non-clinically relevant increases in psychopathology, Quality-of-Life Scale total mean change was no better (P = 0.066) for those given placebo (2.7 +/- 11.0; n = 40) than those treated with olanzapine (5.7 +/- 8.9; n = 174). Path analysis indicated a direct effect of treatment (approximately 29%) on quality of life that was not accounted for by differential changes in psychopathology. In conclusion, stable patients with schizophrenia who were taken off active drug treatment experienced no greater improvements in long-term quality of life than those who were continued on antipsychotic treatment, even in the absence of psychotic symptoms.
