摘要：This Campbell systematic review examines the effects of cognitive behavioural therapy (CBT) when used in outpatient settings to reduce drug use (of e.g. cannabis, amphetamines, ecstasy, or cocaine) among young people aged 13‐21. The review summarizes findings from seven studies, all of which were randomised controlled trials. CBT is not any better at reducing the use of non‐opioid drugs among adolescents than other treatments when used in outpatient settings. The review is based on only a small number of studies, several of which show weaknesses and flaws in their methodology. There is a need to fund additional trials of CBT interventions, based on rigorous study designs and with a potential to add to the global CBT evidence base. The majority of included CBT studies were conducted in the U.S. The findings of this review may therefore only have limited applicability in other social and cultural settings. Future trials of CBT interventions should be conducted in a broader range of countries.
