Disorganized Attachment

Disorganized attachment is an infant attachment pattern identified by the researchers Mary Main and Judith Solomon in 1986 as a fourth category beyond the three original patterns, secure, anxious-ambivalent, and avoidant, that Mary Ainsworth had described in her Strange Situation procedure, added after Main and Solomon noticed that a meaningful number of infants displayed behavior toward their caregiver that did not fit cleanly into any of Ainsworth's original organized strategies. Infants showing this pattern display contradictory, disoriented, or seemingly fearful behavior in the caregiver's presence, such as approaching the caregiver while looking away, freezing in place with a dazed expression, or beginning to approach and then abruptly retreating, patterns Main and Solomon interpreted as reflecting a fundamental conflict: the caregiver, who should ordinarily function as a source of safety, is simultaneously experienced by the infant as a source of fear, leaving no single coherent strategy available for managing distress. Research has consistently linked disorganized attachment to more severe disruptions in early caregiving, including child maltreatment, and also to caregivers who are themselves struggling with unresolved trauma, loss, or frightening and frightened behavior of their own that they inadvertently display toward the infant, even without any deliberate intent to harm. Disorganized attachment has been identified in longitudinal research as carrying a substantially elevated risk, compared with the other attachment patterns, for later behavioral, emotional, and psychiatric difficulties, and it forms the developmental backdrop against which clinical conditions such as reactive attachment disorder are later diagnosed.
