Discussion
Overall, severity of addiction does not seem to be differentially influenced by the interventions from studies included in this review. TSF improved scores in drinking consequences in the same way as other comparison treatments, though regression to the mean cannot be discounted as a factor. Similarly, there is no conclusive evidence from a number of different studies to show that AA helps patients to accept therapy and keep patients in therapy any more or less than other interventions. Similarly, there was no evidence that other TSF interventions impacted the number remaining in treatment any more or less than relapse prevention treatment.
