Background: Patients with severe alcohol use disorder (SAUD) demonstrate multifaceted impairments in social cognition abilities, including emotional decoding or Theory of Mind. Such impairments are associated with real‐life interpersonal difficulties, which in turn could contribute to the persistence of SAUD. However, little is known regarding how patients with SAUD make decisions in a social context and this literature has not been comprehensively reviewed. Objectives: The main aim of this paper was to conduct the first review specifically focusing on social decision‐making abilities in SAUD. Following PRISMA guidelines for scoping reviews, we describe existing knowledge regarding the difficulties experienced by patients with SAUD during social interactions. Our second objective was to propose perspectives for future research, based on the shortcomings identified in the available literature. Design: We searched three online databases (PubMed, PsycINFO, and Scopus) and identified 14 papers using behavioral tasks to assess social decision making in patients with SAUD. Results: Included studies assessed social decision making through three paradigms: (1) economic games (four papers), (2) moral dilemmas (four papers), and (3) interpersonal problem‐solving (six papers). Results indicated that patients with SAUD behave differently from controls in all three paradigms. Conclusions: Previous studies suggested large‐scale social decision‐making impairments or biases in SAUD. However, in light of the limited number of studies available and of the restricted set of processes measured, we call for the extension of this field through more ecologically relevant and model‐based paradigms in order to elucidate the underlying mechanisms of these effects.
