LETS Act: a behavioral activation treatment for substance use and depression

Purpose Substance use disorders (SUDs) often co-occur with major depressive disorder (MDD), yet treatments targeting this comorbidity are limited, especially in resource limited settings where individuals with SUDs often receive treatment. Design/methodology/approach Based upon principles of reinforcement and behavioral economic models of substance use, as well as the Brief Behavioral Activation Treatment for Depression (BATD; Lejuez et al., 2011), the Life Enhancement Treatment for Substance Use (LETS ACT; Daughters et al., 2008) was developed to meet the unique needs of patients with MDD-SUD comorbidity. Findings The current manuscript presents a summary of the theoretical foundations and key components of LETS ACT. Originality/value A specific focus on increasing dissemination via the flexible delivery dependent on patient and treatment setting characteristics is provided throughout.
