GroupA(29): depressive personality was present before and persisted after treatment. GroupB(5): depressive personality scores became higher after treatment. GroupC(15): depressive personality was present before treatment and decreased to within the normal range after treatment. GroupD(15): depressive personality did not appear either before or after treatment. There were no significant differences in any parameters among the four groups by ANOVA.
