Scale for the Assessment of Positive Symptoms (SAPS)

This scale is assessed by the interviewer, and is used tomeasure the level, distribution, and severity of positive symptoms of schizophrenia. It consists of 4 subscales and 34 items evaluating the evangelists, delusions, strange behavior and formal thought disorder. Each item has a score of 0 to 5, with a total score of 0–170. The scale was developed by Andreasen [11] and the adaptation of the Turkish form was made by Erkoç et al. (Erkoç et al., 1991, Düşünen Adam, not indexed in SCIE).
