In terms of reduction of self-reported drinking measures, this review shows that TSF helps to reduce alcohol consumption similarly to other comparison interventions, though without a no treatment control group conclusions are limited. Two studies comparing TSF to other interventions showed a similar reduction in alcohol consumption in all groups. It was not clear whether AA specifically helps people to reduce drinking during treatment and at follow up compared with other interventions. Three studies comparing AA in different conditions with other interventions found few differences between interventions in reducing amount of drinks and percentage of drinking days.
