Twenty-Item Toronto Alexithymia Scale (TAS-20)

The 26-item Toronto Alexithymia Scale (TAS) was developed in 1985 as the first reliable and valid self-report measure of the alexithymia construct. It was modified in 1992 to develop a revised and improved twenty-item version, which is called the Twenty-Item Toronto Alexithymia Scale (TAS-20). The TAS-20 has become the most widely used measure of the alexithymia construct. Articles reporting the development and psychometric properties of the TAS-20 are listed on the Recent Publications page of this website.
Investigators are encouraged to use the TAS-20 in their research on the alexithymia construct. A package containing a master copy of the scale, scoring instructions, reliability, validity, and normative data can be obtained upon payment of a copyright fee of US$40.00 or CAN$50.00. Cheques should be made payable to the Department of Psychiatry, Mount Sinai Hospital and sent to the attention of Dr. Graeme J. Taylor at the following address. Unfortunately we are unable to process credit card payments at this time, nor can we accept payment by electronic bank transfer. For faster delivery, please include your email address with your cheque and the package will be sent as an attachment file.
