testing the efficacy of an online integrated treatment for comorbid alcohol misuse and emotional problems

Conditions: Alcohol Use Disorder

Summary: considering the high comorbidity between alcohol use disorders and emotional problems, there is currently a need for accessible, integrated treatments designed to target both disorders simultaneously. evidence suggests that the combined use of cognitive behavioural therapy (cbt) and motivational interviewing (mi) may be effective at reducing the combined symptoms of the two disorders. however, much of the empirical work has focused on testing the usefulness of cbt/mi for alcohol misuse and comorbid depression, and the majority of these studies involve in-person treatment. therefore, additional empirical research is required to determine the efficacy of combined cbt and mi for alcohol use and both anxiety and depression using an online intervention. this may help inform future treatments in this domain, and potentially be able to inform the development of online, accessible interventions for this population. participants (n = 214) with elevated levels of alcohol use and emotional problems will be recruited from central and eastern canada. participants will be randomly assigned to either the treatment group (i.e., combined cbt and mi), or the psycho-educational control group. individuals in the treatment group will be given 8-weeks to work through 12 online modules. throughout the modules, participants will identify goals related to alcohol use and mood, learn strategies to cope with alcohol cravings, triggers, and social pressures, and learn how to prevent relapse. modules will also include content designed to target anxiety and depression, focusing on strategies designed to help reduce negative thinking and worry, increase behavioural activation, and increase self-care (e.g., relaxation techniques, sleep hygiene). participants randomly assigned to the control (i.e., psycho-education) condition will receive links to websites that provide general psychoeducation about alcohol and mental illness. all participants will complete online assessment measures at baseline, at the end of treatment, and at follow-up approximately 4 months later) in order to assess the efficacy of the treatment. at the end of the study, individuals in the control group will be given full access to the treatment.
