The Ritvo Autism & Asperger Diagnostic Scale (RAADS) is a psychological self-rating scale developed by Riva Ariella Ritvo (NPI UCLA and CSC Yale). An abridged and translated 14 question version was then developed at the Department of Clinical Neuroscience at the Karolinska Institute, to aid in the identification of patients who may have undiagnosed ASD.
The following diagnostic systems and rating scales are used in psychiatry and clinical psychology.This list is by no means exhaustive or complete. For instance, in the category of depression, there are over two dozen depression rating scales that have been developed in the past eighty years.

These function scores are each divided by 6 (the number of scores in each set). Parent and child function scores are then summed and divided by 2 to determine the mean function score. The function with the highest mean score is considered the primary cause of the child's school avoidance. The function divisions are as follows:
Most R scores fall between 15 and 35, but any real number is a possible R score since the z-scores tend to positive or negative infinity as the standard deviation decreases. To guarantee that a grade of 100 produces an R score of at least 35, an adjusted Z score formula guaranteed to produce a result above 35 is used.
Each item yields a score of 0 to 6; the overall score thus ranges from 0 to 60. [4] Higher MADRS score indicates more severe depression. Usual cutoff points are: 0 to 6: normal [5] /symptom absent [4] 7 to 19: mild depression [4] [5] 20 to 34: moderate depression [5] 35 to 60: severe depression. [5]
