Psychological Scales Guide
Heard the name of a scale and wondering what it is for? This guide explains, in plain language, what common psychological scales measure, how they are scored, and why a result never makes a diagnosis on its own. Every page is reviewed by a clinical psychologist.
Scales = an information guide
On these pages you read what a scale is and how it is interpreted. You do not take a test; you understand the scale.
Have a result to talk about?
If a result is on your mind, you can start with an intake and talk it through with a clinical psychologist.
