This is excerpted from a Jack Trimpey / Albert Ellis Debate (1994) on AVRT, which pretty much sums up the difference between AVRT and a "reasoning" approach, in my opinion.
"AVRT declares that the sole cause of all substance addiction is the Addictive Voice, which is the cognitive-emotive expression of an immutable, substance-specific appetite for the pleasure produced by those substances. The Addictive Voice is accepted as a permanent feature of one's psyche, partitioned off from the "true self" through a number of simple dissociative techniques, and then observed rather than acted upon...
In AVRT, there are no conditions for abstinence or for relapse, nor are there any triggers, warning signs of relapse, psychiatric diagnoses, or thresholds of tolerance, that suffice to justify or explain why one would choose to self-intoxicate. AVRT is a mental sorting skill - a filter - that prevents any further use of alcohol or drugs, regardless of "disposing factors." It is completely independent from all philosophies, schools of psychology, and religious doctrines. Indeed, those epistemologies and methodologies, when posed as a primary means to achieve abstinence, may be properly identified as the Addictive Voice itself...
AVRT creates a combative, oppositional attitude patterned after the Addictive Voice itself, and it is not a contemplative, reasoning, approach like REBT."
