Abstract: It consists of 34 items originally designed to develop a clinical tool that assesses beliefs regarding the possible consequences of a change in using behavior.

Psychometric characteristics: The instrument shows an adequate reliability: alpha 0.93
No. of items: 34
Way of administration: Structured, self-administered questionnaire
Way of qualification: The scores in each of the items are added up.
Application context: Treatment Centers and the general population
Population: Alcoholics
