Cognitive behavior therapy (CBT) is widely acknowledged to be the most well-researched, and possibly the most effective therapy option for a wide variety of disorders. The problem is that it is not widely available, particularly in the treatment of patients with substance abuse disorders. In this new study, researchers developed a computer-based training in CBT skills(cutely labeled CBT4CBT) specifically for the treatment of substance abuse. This program consisted of six lessons based on a CBT manual published by the National Institute on Drug Abuse. Each lesson begins with a movie illustrating a vignette in which a substance abuser fails to use appropriate skills (for example, is unable to refuse a drug when offered). This is followed by a description of the cognitive skills required and then by are petition of the video taped vignette in which the drug user is able to successfully use the relevant skill. Other components of each lesson include interactive assessments of symptoms, instructions on how to generalize CBT principles to situations other than substance abuse, and a videotape of a patient completing a homework assignments based on the lesson. Participants are then given the same assignment to take with them.
