Shared social competence impairment: Another link between the obsessive-compulsive and autism spectrums?

Recently, there has been a growing interest in the phenotypic, pathogenic, and pathophysiological overlap between autism spectrum disorders (ASD) and obsessive-compulsive spectrum disorders (OCSD). However, social competence impairment is one domain of overlap that has received less attention. Codified as one of three diagnostic categories in ASD, pathological social processing has also been demonstrated in OCSD. Yet, to date no reviews have synthesized the research literature on social competence impairments in OCSD, especially impairments that may parallel those found in ASD. The current review set out to examine the extant literature in this area in the service of advancing understanding of shared phenomenology between these two spectrums of conditions. Further, delineation of shared social competence impairments between ASD and OCSD might highlight candidate endophenotypes for further investigation. Ultimately, understanding the links between OCSD and ASD may aid in development of better intervention and prevention strategies, some of which may directly target maladaptive social processing.

Research Highlights
► Individuals with OCSD and ASD may share social functioning problems.
► Shared social functioning problems may be related to certain endophenotypes.
► Phenotypic, pathophysiological, and pathogenic endophenotypes may be involved.
