Psychosocial functioning and health-related quality of life in children and adolescents treated with open-label ziprasidone for bipolar mania, schizophrenia, or schizoaffective disorder.
OBJECTIVE
The aim of this study was to examine global functioning, health-related quality of life (HRQOL), and clinical outcome in children and adolescents with bipolar I disorder, schizophrenia, or schizoaffective disorder following ziprasidone treatment.


METHODS
Sixty-three subjects (aged 10-17 years) received open-label ziprasidone, titrated from 10 to 40 mg twice a day (b.i.d.) (low-dose group) or from 20 to 80 mg b.i.d. (high-dose group); fixed doses were used until week 3, followed by flexible doses for 6 months. The Children's Global Assessment Scale (CGAS) characterized functional impairment at baseline and following treatment. The Child Health Questionnaire (CHQ) assessed HRQOL at baseline.


RESULTS
Baseline CHQ showed greater impairment in psychosocial functioning than in physical health. Baseline mean CGAS scores were substantially below normal (i.e., <70), indicating functional impairment. Improvement in CGAS scores occurred as early as the first week of treatment. The low correlations between both CHQ and CGAS and the efficacy measures at baseline indicate that these scales measure different constructs. Nevertheless, there was good correlation between improvements in the CGAS and changes in Brief Psychiatric Rating Scale-Anchored (BPRS-A) and Young Mania Rating Scale (YMRS) during ziprasidone treatment.


CONCLUSIONS
CHQ and CGAS scales may be useful together with standard efficacy measures for children and adolescents with these disorders.
