Background and objectives: Substance use disorders (SUDs) are present in up to 70% of patients with bipolar disorder (BD) and contribute to high rates of disability, morbidity, and treatment non-adherence. Despite this prevalence, few trials have investigated targeted psychosocial interventions for comorbid BD and SUDs.
Methods: Using PubMed and PsycINFO, we conducted a search of the literature up to January 2018 for psychosocial interventions targeted to patients with comorbid BD and SUDs. We identified eight total trials. Of these studies, four randomized and two open trials targeted the types of substance use (alcohol and illicit drugs) of primary concern to mood stability; the remaining two studies, both open trials, targeted smoking cessation.
Results: None of the randomized trials provided consistent evidence for management of both mood symptoms and substance use though integrated group therapy (IGT) demonstrated consistent beneficial effects on substance use outcomes. Other treatments showed benefit for mood symptoms without benefits for alcohol or illicit substance use. Small pilot studies of combined treatments for smoking cessation provided some initial promise.
Conclusions: At present, IGT is the most-well validated and efficacious approach if substance use is targeted in an initial treatment phase. For a subsequent phase, additional psychosocial BD treatments may be needed for mood and functioning benefits.
Scientific significance: This review synthesizes the psychosocial interventions that have been conducted in comorbid BD and SUDs while also providing a perspective on which intervention elements are helpful for addressing substance use versus mood symptoms in patients with these co-occurring conditions.
