Which disorder primarily features social awkwardness and emotional detachment?

Schizoid Personality Disorder is characterized predominantly by a pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings. Individuals with this disorder often prefer solitary activities and may have little interest in forming close relationships, including those with family members. This emotional detachment is a hallmark of the disorder, as individuals typically display indifference to social norms and emotional interactions, leading to feelings of aloofness and isolation.

In contrast, Obsessive-Compulsive Disorder is primarily marked by the presence of obsessions (intrusive thoughts) and compulsions (repetitive behaviors), which do not primarily involve social awkwardness or emotional detachment. Borderline Personality Disorder is characterized by instability in interpersonal relationships, self-image, and affects, along with marked impulsivity, which is contrary to the features of social withdrawal seen in Schizoid Personality Disorder. Paranoid Personality Disorder centers on pervasive distrust and suspicion of others, rather than the emotional and social detachment emphasized in Schizoid Personality Disorder. Thus, Schizoid Personality Disorder is the most accurate choice for defining a disorder with these specific defining traits.
