Disorganized attachment
Disorganized attachment is a category that Mary Main and colleagues added to infant attachment research in the 1980s. It describes infants whose reactions to a caregiver don't form a consistent strategy, for example approaching and freezing at the same time. In adult self-help language it's often used interchangeably with fearful-avoidant.
The longer explanation
In the infant research the key feature is a breakdown of strategy: the child seems to want comfort and to be alarmed by its source. Wikipedia's summary quotes the original description of behaviour that "does not appear to the observer to be coordinated smoothly." Disorganized attachment is studied in relation to frightening or highly inconsistent caregiving, but researchers caution against assuming any particular history from the label.
In adults the closest research category is usually fearful-avoidant (high anxiety plus high avoidance).
Example
An adult describes feeling desperate for a partner's attention, then panicking and shutting down as soon as they get it. Self-help writers might call this "disorganized." A clinician would want much more context before saying anything.
What it is not
It isn't a diagnosis, and it isn't proof that someone was abused. It shouldn't be used as an insult for someone whose behaviour confuses you.
Online use vs research use
The infant category comes from careful observation. The adult internet term is much looser and often swaps in for "chaotic."
Chaos isn't chemistry.
