The NY Times has an article ("Talk Therapy Lifts Severe Schizophrenics") that discusses cognitive behavioral therapy for people with schizophrenia. The experimenters used the same kind of therapy that is used for depressive people to treat the "negative" symptoms (listlessness, exhaustion and emotional flatness) of schizophrenia.
Just as with depressives the therapy consisted of a combination of addressing false beliefs (like that you are not worthy of the attention of others) and goal setting. It took longer than with depressives but they got good results.
There are also CBT therapies that address the "positive" symptoms of schizophrenia (like the hallucinations) but these are not discussed in te article.
