Schizophrenia is among the most severe forms of mental illness, yet some people with the disease are as happy as those in good physical and mental health, according to a new study. “People with schizophrenia are clearly less happy than those in the general population at large, but this is not surprising,” said the lead author. “What is impressive is that almost 40 percent of these patients are reporting happiness and that their happiness is associated with positive psychosocial attributes that can be potentially enhanced.”
