Which phase refers to periods with only negative or attenuated criterion A symptoms?

• A. Prodromal/Residual Periods in Schizophrenia
• B. Symptoms of Schizophrenia
• C. Treatment Nonadherence Predictor
• D. Relapse in Brief Psychotic Disorder

Answer: (A)

Negative or attenuated criterion A symptoms define the prodromal or residual phases of schizophrenia. In these phases, the full set of active psychotic symptoms isn’t met, but there are lingering signs: negative symptoms such as reduced motivation, social withdrawal, flat affect, or alogia, and sometimes mild, attenuated positive symptoms that aren’t severe enough to meet the diagnostic threshold. The prodromal phase comes before a full psychotic break, while the residual phase follows an acute episode and may persist with these lasting symptoms. Other options don’t describe a phase where only negative or attenuated criterion A symptoms are present.
