The DSM-IV-TR (APA, 2000) lists three negative characteristic symptoms of schizophrenia: alogia, affective blunting, and avolition. Other common negative symptoms include anhedonia and attentional impairment. Poverty of speech is classified as a negative symptom, while hostility, bizarre behaviors, and thought disorders are considered to be positive symptoms.
