First published: 10 May 2019 | Last updated: 20 May 2019

Aim: The aim of this study was to describe the development and validation of the UK Alcohol Treatment Trial Process Rating Scale (UKATT PRS), a manual based method for monitoring and rating the delivery of psychosocial treatments of alcohol dependence and misuse.

Methods: Following adaptation and further development of a validated rating scale, the ability of the UKATT PRS to rate the delivery of video-recorded treatment in the UK Alcohol Treatment Trial (UKATT) was tested.

Results: Tests of the validity and reliability of the UKATT PRS show that it is valid and reliably able to detect the two treatments for which it was designed and to discriminate between them.

Conclusions: The UKATT PRS is a valid and reliable method of rating the frequency and quality of therapeutic style and content in the delivery of two psycho-social treatments of alcohol use and dependence.
