Deficits in social functioning are prevalent in individuals with schizophrenia and can often be as debilitating as
the illness itself. Recent research has suggested that problems in social functioning can be seen long before the onset of
schizophrenia and are generally present throughout the course of the disease. Recent literature on social functioning is
critically reviewed for high-risk groups, first-episode psychosis, and later schizophrenia. Deficits in social functioning
begin as early as childhood and often continue throughout the course of schizophrenia. However, social functioning can
stabilize or even improve later in the course of the illness. Implications and directions for future research are discussed.
