What is the Toronto Alexithymia Scale?

Introduction

The Toronto Alexithymia Scale is a measure of deficiency in understanding, processing, or describing emotions.

Background

It was developed in 1986 and later revised, removing some of the items.

The current version has twenty statements rated on a five-point Likert scale.

The reliability and validity of the TAS-20 was established by a series of articles by Bagby and colleagues (1994).
