Symptom MeasuresState
Paranoia. Five visual analog scales were used to assess state paranoia: (1) I am being deliberately harmed or upset; (2) I am being followed; (3) There is a conspiracy against me; (4) I am being persecuted; (5) I am being laughed at behind my back. For each item, participants rated how they were feeling “right now” from 0 (not at all) to 100 (totally). A total score was used. The internal reliability of this scale was high (Cronbach alpha = 0.86).
