title: Dyadic splitting in partner relational disorders.
abstract: The defense mechanism of splitting appears to underlie many interpersonal problems that are presently classified within the category of relational disorders of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 1994) and, accordingly, bridges individual and family psychology. It is suggested here that certain relationships are marked by specific patterns and characteristics that can best be regarded as dyadic splitting. This article presents an overview of splitting in individuals and couples and reviews empirical studies establishing norms and validity of dyadic splitting, as measured by the Dyadic Splitting Scale. Research with samples of men who batter, battered women who return to their abusers, and couples clinically assessed as being narcissistically vulnerable demonstrates the presence of dyadic splitting in these populations. The notion of a defense mechanism influencing relationship dynamics strengthens the appreciation of mutuality between individual and relationship disorders and holds promise for treatment.
