DSM-IV and DSM-IV-TR (published in 2000) criteria for schizoaffective disorder were poorly defined and poorly . These and unreliable criteria lasted 19 years and led clinicians to significantly overuse the schizoaffective disorder diagnosis.

Psychiatric Disorders: Schizophrenia, Depression and Conduct Disorders

The symptoms of schizophrenia are classified as positive or negative. These classifications help describe the characteristics of the disorder and predict the effects of antipsychotic medication. Positive symptoms are those additional to expected behavior (i.e., “excessive” function) and include delusions, hallucinations, agitation, and talkativeness. Negative (deficit) symptoms are those missing from expected behavior (i.e., decreased function) and include lack of motivation, social withdrawal, flattened affect, cognitive disturbances, poor grooming, and poor or impoverished speech content (see later text). Positive symptoms respond well to most traditional and atypical antipsychotic agents. Negative symptoms respond better to atypical than to traditional antipsychotics (see Chapter 19).

To test whether the differences between the correlations in causal and perceptual words for the two groups (H4) wereinfluenced by differences in essay length, we conducted partial correlations with word count as a covariate.
