Individuals
who match this personality disorder type have an extremely fragile self-concept
that is easily disrupted and fragmented under stress and results in the
experience of a lack of identity or chronic feelings of emptiness. As a result,
they have an impoverished and/or unstable self structure and difficulty
maintaining enduring intimate relationships. Self-appraisal is often associated
with self-loathing, rage, and despondency. Individuals with this disorder
experience rapidly changing, intense, unpredictable, and reactive emotions and
can become extremely anxious or depressed. They may also become angry or
hostile, and feel misunderstood, mistreated, or victimized. They may engage in
verbal or physical acts of aggression when angry. Emotional reactions are
typically in response to negative interpersonal events involving loss or
disappointment.
Relationships
are based on the fantasy of the need for others for survival, excessive
dependency, and a fear of rejection and/or abandonment. Dependency involves
both insecure attachment, expressed as difficulty tolerating aloneness; intense
fear of loss, abandonment, or rejection by significant others; and urgent need
for contact with significant others when stressed or distressed, accompanied
sometimes by highly submissive, subservient behavior. At the same time, intense,
intimate involvement with another person often leads to a fear of loss of an
identity as an individual. Thus, interpersonal relationships are highly
unstable and alternate between excessive dependency and flight from
involvement. Empathy for others is severely impaired.
Core
emotional traits and interpersonal behaviors may be associated with cognitive
dysregulation, i.e., cognitive functions may become impaired at times of
interpersonal stress leading to information processing in a concrete, black-and
white, all-or-nothing manner. Quasi-psychotic reactions, including paranoia and
dissociation, may progress to transient psychosis. Individuals with this type
are characteristically impulsive, acting on the spur of the moment, and
frequently engage in activities with potentially negative consequences.
Deliberate acts of self-harm (e.g., cutting, burning), suicidal ideation, and
suicide attempts typically occur in the context of intense distress and
dysphoria, particularly in the context of feelings of abandonment when an
important relationship is disrupted. Intense distress may also lead to other
risky behaviors, including substance misuse, reckless driving, binge eating, or
promiscuous sex.
