The DSM-5 outlines the following criterion:
- Two or more of the following (for at least a month), and at least one of them must either be 1,2 or 3.
- delusions
- hallucinations
- disorganized speech
- grossly disorganized or catatonic behavior
- negative symptoms (such as diminished emotional expression)
- Impairment in one major area of functioning: work, interpersonal relations or self-care
- Some signs of the disorder must last continuously for 6 months or more.
- Schizoaffective disorder and bipolar or depressive disorder has been ruled out.
Also if the disturbance is not caused by a substance or another medical condition.
I hope this helps!
