Validation of a scale for rating the delivery of psycho-social treatments for alcohol dependence and misuse: the UKATT Process Rating Scale (PRS).

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.
