Voila!

Here you will find an overview of some of the more recent models of personality that conceptualize BPD, an annotated version of the DSM diagnostic criteria in current use in the USA, and a list of further key related behavioral and cognitive patterns often observed in those suffering from BPD.

recommended siteThe Dialectical Behavioral Model [Linehan 1993]
Identifies six behavioral patterns in BPD:

1. Emotional vulnerability. Individuals with BPD have severe difficulty in regulating negative emotions -- including sensitivity to negative emotional stimuli, emotional intensity, and a slow return to an emotional baseline.

2. Self-invalidation. Individuals with BPD have unrealistically high standards and expectations for self with a tendency to invalidate or fail to recognize emotional responses, thoughts, beliefs, and behaviors.

3. Unrelenting crises. Individuals with BPD often engage in "parasuicidal" behavior, i.e., nonfatal, intentional self-injurious behavior that results in actual tissue damage, self-mutilation, and self-inflicted burns, with little or no intent to cause death.

4. Inhibited grieving. Individuals with BPD are often unable to cry or express strong sadness appropriately.

5. Active passivity. Individuals with BPD fail to engage actively in solving their own life problems while actively soliciting problem solving from others.

6. Apparent competence. Individuals with BPD often appear more competent than can be demonstrated through their behavior or accomplishments.


recommended siteThe Diagnostic Interview for Borderlines, Revised (DIB-R) [ Gunderson/Kolb 1989]
This common clinical test looks for these four clusters of symptoms:

1. Affect (subjective feelings)
Chronic/major depression, helplessness, hopelessness, worthlessness, guilt, anger (including frequent expressions of anger), anxiety, loneliness, boredom, emptiness

2. Cognition (intellectual reasoning)
Odd thinking, unusual perceptions, nondelusional paranoia, quasipsychosis

3. Impulsivity (behavioral) Substance abuse/dependence, sexual deviance, manipulative suicide gestures, other impulsive behaviors

4. Interpersonal relationships Intolerance of aloneness, abandonment, engulfment, annihilation fears, counterdependency, stormy relationships, manipulativeness, dependency, devaluation, masochism/sadism, demandingness, entitlement


recommended siteThe Borderline Symptom List [Bohus/Limberger 2001]
This test, developed by the major German researchers of BPD, focuses on seven "BPD factors":

1. self-image
2. affect regulation
3. auto-aggression (self-injurious behaviors)
4. dysthymia (constant low-grade depression)
5. social isolation
6. intrusions
7. hostility


recommended siteZanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD) [Zanarini 2003]
This is a brand-new test specifically designed for clinicians to administer in order to assess changes in BPD symptomatology, developed by Dr. Mary Zanarini, a prominent BPD researcher.


recommended siteThe Personality Disorder Beliefs Questionnaire (PDBQ)
[as implemented by A. Arntz, R. Dietzel and L. Dreessen in: Assumptions in borderline personality disorder: specificity, stability and relationship with etiological factors, 1999.]

This questionnaire (not in general use, but highly interesting) provides 6 sets of 20 "Assumptions" held by those suffering from the various personality disorders. The following 20 have been the most commonly affirmed by those diagnosed with BPD:

1. I will always be alone.
2. There is no one who really cares about me, who will be available to help me, and whom I can fall back on.
3. If others really get to know me, they will find me rejectable and will not be able to love me; and they will leave me.
4. I can't manage by myself, I need someone I can fall back on.
5. I have to adapt my needs to other people's wishes, otherwise they will leave me or attack me.
6. I have no control of myself.
7. I can't discipline myself.
8. I don't really know what I want.
9. I need to have complete control of my feelings otherwise things go completely wrong.
10. I am an evil person and I need to be punished for it.
11. If someone fails to keep a promise, that person can no longer be trusted.
12. I will never get what I want.
13. If I trust someone, I run a great risk of getting hurt or disappointed.
14. My feelings and opinions are unfounded.
15. If you comply with someone's request, you run the risk of losing yourself.
16. If you refuse someone's request, you run the risk of losing that person.
17. Other people are evil and abuse you.
18. I'm powerless and vulnerable and I can't protect myself.
19. If other people really get to know me they will find me rejectable.
20. Other people are not willing or helpful.

Annotated DSM-IV-TR Diagnostic Criteria for Borderline Personality Disorder

These annotations are provided as an informational service only, and should not be viewed as conclusive; for specifics on your individual situation, please consult your mental health professional.


To diagnose a patient as suffering from Borderline Personality Disorder, the
Diagnostic and Statistical Manual of the American Psychological Association IV-TR
[revised edition, 2000]

requires that clinicians follow the following diagnostic criteria:

(Scroll down just a bit to see links to my detailed notes on each criterion, plus a listing of some key behavioral traits and cognitive patterns.)

[*In the following annotations, I use the term "Borderline" to refer to sufferers of this disorder sheerly for the sake of brevity; a human being obviously cannot be defined by a mental disorder alone.]



[For non-USA contexts, also see the World Health Organization's International Classification of Mental Health and Behavioural Disorders -- ICD-10, F60.31: Emotionally Unstable Personality Disorder, Borderline Type]

And here are two personal write-ups of what each DSM criterion feels like to someone who suffers from BPD:
A Personal Reflection
and
Shadowlands

Borderline Personality Disorder

A pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following

Only 5 of the following 9 criteria are technically required for a clinical diagnosis. Some patients demonstrate 5, some demonstrate all 9. Because of the relative looseness of this schema, it is possible for the symptoms to vary quite a bit from person to person. A Borderline who "acts in" by turning their anger onto themself in the form of self-injury (cutting etc) can "quack" very differently from a high-functioning Borderline on the narcissistic end of the spectrum who takes out these aggressions on those around them.

This makes diagnosis extremely difficult, especially given the tendency of those with the disorder to dissimulate in therapy or focus on the symptoms (depression, addiction, etc) rather than on the underlying disorder as causal.

This "5 of 9" standard was set by the DSM-III in 1980, although it has its strong critics, and other diagnostic models are competing for the next release of the DSM, including an adaptation of the "five-factor" model of personality.

It is very important to note that each of these criteria represents a behavior or cognitive pattern shared to some extent by all of us; the pathological nature of these criteria lies in their life-long presence, influence on the sufferer's perception of quality of life, rigidity in the face of all rational counterexplanation, resistance to change, the self-perpetuating nature of the traits, and their effect on the overall functionality of the person in relationships and society.

BPD is a severe mental health disorder with a completed suicide rate of 10 - 12%, one of the highest of all psychiatric diagnoses. An estimated 2% of the general population, 27.6% of all psychiatric patients, 25 - 50% of spousal batterers, and an unknown but estimated 25% of prison inmates in the United States suffer from BPD.

1. frantic efforts to avoid real or imagined abandonment.
[Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5]

These "frantic efforts" can include:
verbal violence
sudden exaggeration of physical maladies requiring caretaking
accusations of abuse
physical blocking of exit pathways to the partner
threats to children or intimate bystanders
suicidal intimations or blatant threats of self-harm
threats to expose actual damaging information shared in confidence
threats to expose fictitious damaging information
threats to destroy, or actual destruction of cherished possessions
threats of sexual infidelity
threats of divorce
compulsive revelation of sexual infidelities
threats of legal retribution
physical attack/abuse

The feared abandonment can be imaginary; that is, virtually anything at all can and may be interpreted as abandonment or 'intent to abandon' by someone with BPD. Borderlines appear to have a hair-trigger response to what they perceive as 'invalidation' of any kind. This becomes extremely frustrating for those who interact with the Borderline, since at times every single word or action (real or referential) may be interpreted as secretly harboring malicious abandonment (it is not coincidental that many partners of Borderlines first wonder whether their loved one suffers from clinical paranoia).

In layman's terms, the Borderline brain is hard-wired for rejection, and someone with untreated BPD may be virtually incapable of perceiving any other outcome to an emotional attachment, despite all rational evidence to the contrary. Tragically, the off-kilter behaviors that accompany this foregone conclusion in their minds are very often the sole cause of relationships and interpersonal attachments falling apart.

Many folks ask why, if a person with BPD is so afraid of abandonment, they are so often the one to terminate the relationship and flee voluntarily. This "first strike" behavior is actually quite logical from the Borderline's perspective: abandon or be abandoned. This subjective sense of personal 'control' over intimate circumstances appears to be very appealing to many with this disorder, all the more so because of a general tendency to perceive so many other life factors as beyond their control.

Another trigger for abandonment fear can be real or imaginary illness on the part of a loved one or partner. Borderlines appear to have an extremely difficult time with the mere possibility of the loss of a loved one, and will often flee (rather than offer support) when confronted with this scenario.


2. a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation.

Folks with BPD appear to have been deeply damaged in their early emotional attachment ("bonding") processes; this finds its expression in the inability to realistically assess the limits and boundaries of interpersonal relationships.

A black-and-white pattern of relating to others -- often called the abandonment/engulfment cycle -- results in the premature idealization of a new friend or partner. This idealization is akin to a kind of juvenile symbiosis unconsciously intended to replace an absent or damaged relationship to a parental caretaker figure. Adults with BPD can move extremely quickly into revelations of a very personal nature and soon become extremely demanding of the time, resources and loyalty of new partners or acquaintances. As reality sets in, the Borderline is often extremely disappointed and discouraged that this new relationship does not (and cannot) replace their subconscious ideal of parental unconditional love.

Additionally, intimacy and trust have an inversely proportional relationship in BPD; this is the least intuitively rational aspect of the disorder. As personal closeness grows, so does the irrational fear that the new loved one/friend will reject the "real" person underneath the complex of BPD. The Borderline begins placing demands of loyalty on the other that get increasingly irrational -- all in the semi-conscious attempt to "prove" that the other will inevitably reject them. These incredibly deep-rooted fears, alas, too often wind up becoming a self-fulfilling prophecy.

Unable to retain a balanced view of the other person (and frightened by the encroaching intimacy they are not emotionally equipped to handle), the Borderline then "splits" the other person into an all-evil representation and demonizes them as utterly uncaring, disappointing, abusive, etc. Often this results in the Borderline completely and arbitrarily severing the relationship (which in turn is extremely hurtful to the person on the receiving end of the dynamic).

When another person is split 'bad', they can do no right. All arguments begin and end with an assignment of blame to the other participant(s). This can reach irrational levels quite quickly -- a Borderline can be so invested (consciously or not) in their self-image as "abandoned victim" that they literally re-write personal history to place themselves in this role. Whereas this tendency is irritating enough in most normal scenarios, it can reach the level of actual legal damage to the other, as in false accusations of abusive or criminal acts. There are many documented instances of this mechanism invoked in disputed custody cases, for instance.

See this page for more on the "rescripting of memory" in BPD.

This splitting can reverse itself with surprising speed. There is no predicting when or how a partner or friend will be "split back" to sainthood; often this happens when the Borderline has left for another idealized relationship, only to return begging forgiveness when the new person inevitably disappoints. Unfortunately, the cycle is ongoing and, without appropriate treatment intervention, will last as long as the relationship is able to.

American culture places inordinate value on so-called "true romance", which is well simulated by the jealously exclusive Borderline idealization process. This can make it very difficult to distinguish its pathological dimensions at first blush. As the relationship proceeds, many non-Borderline partners who have failed to register the early warning signs of emotional dysfunction are caught very unhappily by surprise in this dynamic when their partner begins cruelly devaluing or abusing them, engages in infidelities, or sometimes suddenly vanishes.

Many non-Borderlines have noticed this idealization pattern quite markedly in the Borderline's relationship to family members and close friends, who may be idealized beyond reason one moment and utterly discarded the next. Possessions, places, pets, philosophies, politics, religious or political beliefs can also be "split" good or evil.

It is very common for Borderlines to express their emotional ambivalence via withholding or rationing of affection, sexual activity, financial support, or other sensitive components of a relationship. There is a specific form of "Borderline Sulk" known among non-Borderline spouses that manifests as an age-inappropriate, aggressive walling-off from all communication with loved ones.
Yet when the other is split 'good' again, no one can be a more generous, supportive or understanding partner than a Borderline. This leads loved ones to frequently comment on the Dr. Jekyll/Mr. Hyde persona of folks with BPD.

Perhaps most importantly of all, Borderlines primarily split themselves. This fundamentally shaky relationship to self is the backbone of many clearly identifiable BPD behaviors and feelings. A person with BPD often finds it near-impossible to take accountability for small errors without vilifying themself completely and risking utter self-hatred. They tend to hold themselves to a standard of inhuman perfection -- and to fail in even the smallest way, in their minds, is to court justified self-annihilation. The often-noted inability of those with BPD to apologize for (or even acknowledge) mistakes they've made can be related back to this splitting mechanism.

3. identity disturbance: markedly and persistently unstable self-image or sense of self

Some Borderlines have an almost eery chameleon-like quality to their social interactions: voice, gestures, clothing, opinions can change according to the person or group being idealized at the moment.

Lacking a stable relationship to self, it is common for folks with this disorder to exhaustively question every fundamental belief others may take for granted: their religious convictions, sexual orientation or preferences, moral precepts, goals and purpose in life. Unable to provide it for themselves, Borderlines consistently seek external validation of their self-value. Often, the assimilation into a group with strict guidelines and principles (military, religious or even cultist organizations) can substitute for this acceptance.

Another facet of this lack of identity is an observed tendency on the part of those with BPD to frequently quit jobs and/or change careers. In many ways, even an older person with BPD can be much like a teenager fresh out of high-school, unsure of their future goals and plans and reluctant to commit to one career path.

Many loved ones wonder whether the person with BPD in their life suffers from Multiple Personality Disorder (now known as Dissociative Identity Disorder), because their self-presentation can shift so radically from situation to situation. This has many causes, one of them being a tendency of those with BPD to dissociate under stress [see criterion 9, below].

4. impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating).
[Note: Do not include suicidal or self-mutilating behavior covered in Criterion 5]

Some studies have found that over 60% of those with addictive problems also suffer comorbid personality disorders. This status of "dual diagnosis" makes treatment much harder; causality can be very difficult to pinpoint in these cases. Mind-altering and escape-promising substances and habits are extremely tempting to those suffering the constant emotional pain of this disorder.

There is some biochemical evidence that the same neural pathways damaged by the disorder are also those which can render a person prone to addictions of all kinds. Certainly alcoholism, sexual addiction, and substance abuse are commonly found in this clinical population.

See these links for more on addictions and BPD.

Life-threatening road rage and a yen for aggressive public confrontation with service persons or strangers can be displayed by folks of both sexes with BPD. This appears to relate to an extremely short fuse for tolerating delay or apparent dismissal, and may be related more closely to Criterion 2.

Eating disorders (in particular) and impulsive behaviors such as spending sprees, shoplifting, gambling or hair-pulling are often comorbid with BPD. Compulsive behaviors such as situation-inappropriate hoarding of food or clothing, extreme skin-picking or Body Dysmorphic Disorder (an unrealistically negative image of one's body) are commonly co-diagnosed as well.

See these links for more on Impulse Control Disorders, Compulsive Disorders, Eating Disorders and BPD.

5. recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior

Once upon a time, when a person received a diagnosis of self-injurious behavior (cutting, self-harm, self-mutilation), the diagnosis of BPD followed right behind. Although modern psychology has learned to distinguish between the two, a general rule of thumb is that whereas not all self-injurers have BPD, many folks with BPD -- although not all! -- self-injure in some fashion.

Cutting or burning one's own skin with knives, pins, razors, cigarettes or cigarette lighters are the most commonly known expressions of self-injury. Abuse of alcohol and controlled substances or street drugs could also be considered self-injury, as could the reckless practice of unprotected sex with strangers of dubious status vis-a-vis sexually transmitted diseases. A marked tendency to neglect physical self-care, to the point of often becoming physically ill when easily preventable, also points in the direction of a self-destructive mind-set.

The secret habit of literally inducing illness in oneself is a separately diagnosed disorder known as Munchausen's Syndrome. Here, folks deliberately harm their bodies by breaking their own limbs, insisting upon unnecessary invasive surgery, or ingesting or injecting toxins. While not technically the same disorder, Munchausen's shares a large diagnostic overlap with BPD.

Extreme amounts of tattoos or piercings, constant skin-picking or extreme shaving, severe restriction of diet or sleep according to arbitrary rules, fanaticism for the questionable "quick-results" promises of non-mainstream health fads -- these may all be indicative of self-injurious tendencies when observed in the presence of other diagnostic criteria for BPD.

For more on self-injury and eating disorders, see these links.

6. affective instability due to a marked reactivity of mood (e.g., intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days)

There is a big debate in the mental health community over whether BPD can be viewed as a subset of Bipolar Disorder, and I address this debate elsewhere on this site. As mental health professionals continue to research the topic, the salient point for diagnostic purposes is that a person with BPD is subject to extreme and sometimes astonishingly rapid shifts of mood.

It is quite common for someone with BPD to feel literally suicidal one moment, and an hour later feel "fine" and wonder what all the fuss is about.

Technically speaking, even rapid-cycling Bipolar Disorder (known as Bipolar II) does not cycle that rapidly. These mood shifts may occur many times a day in someone with BPD. There is a marked tendency towards drama and chaos -- Borderlines often lead themselves into crisis situations as though they can't control it. This "addiction to crisis" may have both learned and biochemical roots.

These mood shifts appear to be triggered both by internal as well as by external sources or triggers -- sources, however, which the person with BPD is not often capable of identifying on their own. Standard soothing techniques used with people suffering from depression, while sometimes helpful in the short run, are ineffective in changing the course of these Borderline moods. It remains unclear what part of these BPD up- and down-swings are due to actual affective disturbance (a possible genetic component) and what part to self-destructive cognitive patterns.

7. chronic feelings of emptiness

Borderline "emptiness" is often confused with boredom or depression. Lacking a sufficiently mature sense of self, or identity, a person with BPD is highly likely to fall into a lethargic, painful dysphoric state in which nothing and no one seems appealing.
[dysphoria="a feeling or spell of dismally low spirits", constant low-grade misery]

This is most often encountered when the Borderline has no intimate relationship or during cycles of long-term committed relationships after the idealization period has worn off. Most apparent here is the Borderline's seeming inability to relax, to enjoy peaceful down-time (without crisis!) in the company of friends and loved ones, to occupy oneself alone with hobbies or interests for any extended length of time.
For more information on BPD & depression, see these links.

Borderline "emptiness" is often frantically assuaged with the acquisition of material possessions or money, adrenalin-seeking behaviors and addictions. Hoarding/collecting behaviors and a tendency towards addictive substances are both subjectively intended to combat these extremely unpleasant sensations of diffuse "lack."

Indeed, a sense of entitlement or insistence on the "right" to make up for perceived discriminatory withholding of resources (affection, material objects, schooling, privilege, children, etc) -- despite factual evidence to the contrary -- is a key BPD cognitive pattern in this context.

8. inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights)

Only a few "primitive" emotions are easily accessible to someone suffering from BPD -- and situationally inappropriate anger is chief among them. Lacking a more differentiated capacity for expressing (or even recognizing) intense emotion, a person with BPD is easily triggered into towering, inappropriate rage. Unfortunately, this rage is then aimed at anyone in an intimate relationship with this person, transforming it from merely regrettable emotional underdevelopment into true interpersonal or domestic violence. Rages can come on with astonishing speed and violence, and are very difficult to explain to anyone who is only nominally acquainted with the person with BPD.

The person with BPD tends to dissociate during periods of rage, during which they are not responding to the current surroundings and situation, but rather to a traumatic incident in their past. This can render them virtually oblivious to the effect of their rage on others, which can be highly dangerous. A Borderline in a full-blown rage is not a person to be reasoned with or otherwise tolerated -- if the rage is clearly out of control, it is appropriate to remove oneself from the immediate area and notify the authorities.

Rages are in general brought on by a triggered suspicion of abandonment or an intimation of criticism/invalidation, and can include (as in Criterion 1):
shouting
uncharacteristic cursing
harsh verbal abuse
physical abuse, domestic violence
threats to children or bystanders
the destruction of property
self-injurious episodes

Besides physical violence to their person, numerous non-Borderlines report having experienced incidents such as holes punched in the walls, telephones ripped out, furnishings destroyed, knife battles, gunplay, arson attempts, and other extremely dangerous (even potentially deadly) incidents. It's the unpredictability of these rages, and the seemingly innocuous events that precipitate them, that are so very difficult for those in relationships with a Borderline to tolerate.

[Note: if you find yourself in this situation with a loved one, remove any lethal weapons from the home and please read these resources immediately.]

Although raging is certainly one of the more universal hallmarks of the disorder, some folks with BPD do not appear to rage as violently or frequently as others. Some researchers characterize these tendencies as "outward-acting" and "inward-acting" -- the former taking their anger out on those around them and the latter on themselves in the form of self-injury. Many cases appear to be a mix of both, depending on the situation.

9. transient, stress-related paranoid ideation or severe dissociative symptoms

Times of stress can bring anyone's most dysfunctional coping mechanisms to the fore, and this is particularly true in someone suffering from BPD.
Chief among these is dissociation, or the subjective re-playing of past traumas in present scenarios. A tone of voice, sound, sight or smell may 'trigger' the dissociation by stimulating the part of the brain keyed to remember past injury. In self-defense, the Borderline dissociates, removing themself emotionally from the present source and responding to it as though it were the past situation. Dissociation is particularly common in survivors of childhood sexual abuse.
For many more details on dissociation, see these links.

Most Borderlines suffer from the belief that people are fundmentally ill-willed towards them and will ultimately betray and abandon them. (See this list for an excellent summary of common beliefs held by people with BPD.)

Paranoid ideation can include the temporary conviction that loved ones are poisoning, illicitly harming, or (quite common) committing infidelities behind the Borderline's back -- all despite overwhelming objective evidence to the contrary. If the paranoia extends beyond the belief that intimate loved ones will ultimately abandon them (for instance, if the person sees patterns of actual personal persecution in random unrelated events, is abrasive with everyone, seeks no friendships, often fears being spied or evesdropped upon, or sees murderous intent in all strangers), and appears long-lasting, an alternate diagnosis of Paranoid Personality Disorder might be considered.

Criterion 9 can also include brief periods of psychosis. This involves true unlinking from reality -- seeing headless angels descending, hearing voices issuing dire commands, engaging in extreme self-injury such as attempted auto-castration. Depending on the severity and duration of the psychotic episode(s), the person with BPD may carry an additional diagnosis of "depression with psychotic features."

If the person with BPD exhibits episodes of manic behavior -- wild euphoria, delusions of personal invincibility, taking on the persona of famous characters -- an alternate or comorbid diagnosis of Bipolar Disorder may be considered.

Key BPD-Related Behavioral and Cognitive Patterns

'One law for me, another for everyone else'

This kind of blind universal self-exception is fundamental to the cognitive distortions that underlie all personality disorders. It is the entrenched rigidity of this belief in the face of all rational counter-argument -- and many folks with BPD are above-average in intelligence -- that defines the very pathology of BPD.

Common variations include "I'm allowed to have affairs but my partner is not", "I'm not an addict but others using these same drugs/substances are", or "I am a devout Christian [or other religious or political adherent] and nothing I do contradicts this."

Extreme Foreshortening of Emotional Horizons

Observers usually note that a person with BPD will retain an impressionistic emotional memory of others based solely on the most recent interaction with that person. Their cognition and memory being impaired by a noradrenalin-maintained hypervigilance, folks with BPD are commonly unable to take a longer-term perspective on life events. Certainly this factor plays into the impulsive behaviors associated with this disorder -- stories are legion of Borderlines 'burning their bridges' in many contexts.

Linked to this is the distorted cognitive principle that "Feelings Create Facts", next:

"Feelings Create Facts"

The deeply entrenched belief that the subjective, fleeting feelings of the moment determine all reality forever ... or at least until the next impression sets in.

For complex reasons, Borderline pathology includes a relatively fast-and-loose relationship to historical fact when the individual is emotionally aroused in some way. If a Borderline feels abused, in their mind, abuse must have factually happened. For obvious reasons, this is an extremely confusing world-view for others to comprehend; all the more so, given the obvious intellectual clarity of the individual in other contexts.

For more on this, see: Memory and BPD

"Attention is a Zero-Sum Game"

Many Borderlines are incapable of perceiving the limitless quality of emotional affection or attention in general. If someone else receives praise or notice, Borderlines fear that there will be less to go around for them. The recognition received by anyone else, the reasoning goes, has the effect of personally dimishing the Borderline, and they immediately take a hostile, defensive stance against this perceived new 'enemy.'

This apparent jealousy is not a rational cognitive process, and many non-Borderlines have remarked on the highly age-inappropriate behavior of Borderlines in contexts such as children's birthday parties, others' weddings, spouse's job promotions or similar celebratory events that focus on others. (Imagine, for example, your consternation while attending your law firm's celebration of your attaining full partnership after ten years, to be called into the bathroom by your seething middle-aged spouse sobbing that "you're getting all the attention -- and you'll be sorry!" -- a scenario recently related to me by a site visitor).

In many cases, this jealousy is expressed via seemingly interminable conversations (often in the dead of night) revolving endlessly around one's supposed infideities or "betrayals" as a partner.
In some cases, a Borderline's pathological jealousy of a spouse or partner can express itself in violence, suicide or even homicide; if you find yourself in this situation, please notify the appropriate authorities, as this is an intolerable and potentially very dangerous irrationality to live with. Folks freshly separated from a violent Borderline relationship must take extra care to make use of all legal venues that ensure their own self-protection. Many (possibly preventable) tragedies have resulted from this "If I can't have you, nobody can!" mind-set.

This extreme BPD egocentrism, based as it is on a foundation of anxiety and crippling self-loathing, can lead to innumerable conflicts in life as the Borderline overpersonalizes each interaction in this way -- and struggles resentfully to hang on to what is tragically felt to be a limited quantity of love & attention in the world.

Situational Competency

The intense fear of abandonment, triggered by dysfunctional attachment perceptions, usually applies only to those with whom the Borderline is emotionally intimate, therefore the 'outside world' often sees no irrational behaviors. Someone with BPD who is relatively high-functioning may exhibit little impairment on the job or in other non-familial contexts.

This trait makes it particularly difficult for spouses and family locked in a cycle of domestic abuse to attain external validation of their experiences.

Lack of Object Constancy

"Object Constancy" is a term used in a field of psychology known as Object Relations theory. It denotes the learned ability of a young child to retain a constant internal image of a thing in mind, despite its shifting outward appearance (for instance, the accurate size of a toy whether viewed from close up or from afar. A classic child psychology experiment in this area is the demonstration of two glasses of different sizes containing the same amount of liquid -- can the child perceive that the amount of fluid remains constant when its physical shape changes?).

Folks with BPD have been theorized to possess an unstable object constancy in regards to the loved ones in their lives: when that person is not physically present, someone with BPD slowly loses an emotionally consistent 'sense' of that person's existence. Many non-Borderlines have noted the curious (and often irritating, sometimes even abusive) tendency of Borderlines to telephone excessively, to inappropriately "check up" on their loved one's behaviors outside the home, to keep small physical mementos or photographs of the loved one with them at all times, or to insist that they physically see the partner in person at frequent intervals.

As one person with BPD put it, "It's as though the outlines of the absent person, no matter how well I know them, begin to fade and lose their clarity, leaving room for all sorts of doubts and fears of my own to begin creeping in."

Projection, Splitting, Displacement, Magical Thinking, Triangulation

Read this for a description of some common ego defense mechanisms used by those with BPD.

Gaslighting

After the 1944 film of the same name (Gaslight), in which Ingrid Bergman plays a Victorian newlywed who, through a devious series of manipulations (e.g., slowly dimming the gaslights) by her mentally ill husband, is slowly persuaded that she and not he is the unbalanced spouse.

Many folks with BPD or BPD traits are extremely invested in denying the level of their dysfunction -- personality disorders are "ego-syntonic", or viewed by the individual as a natural and necessary way to think and be. Borderlines may wage a permanent war with all their loved ones as to "who is really the sick one here?"

Blatant denial of events or conversations that have occurred, endless circular conversations on who-did-what-when, and actually changing or removing physical evidence of dysfunctional behaviors are all gaslighting techniques.

It's a commonplace in the psychiatric community that the spouse or partner of someone with BPD is usually the first to present clinically, worried about "going mad" themself.

Interpersonal Manipulation

Quite a bit has been written on the topic of manipulative behavior and BPD. Indeed, people with the disorder have traditionally been stigmatized in the mental health community for precisely this reason: "master manipulators", "emotional vampires" or "users" are terms that unfortunately still get lots of play in clinics and hospitals around the country.

Certainly most of the dysfunctional behaviors expressed by those with the disorder are perceived by others as blatant attempts to sway others into fulfilling their immediate wishes. Borderlines are experts at 'sideways fulfilment' of their needs. Loved ones and others are often drawn into highly complicated interpersonal games whose goals are to provide the Borderline with things the Borderline is seemingly unable (or perceives her/himself as unable) to provide for her/himself -- or to fulfill a misplaced need for "safety."

Whether or not this is a conscious process is up for debate (albeit a debate with enormous legal ramifications); what is certain is that someone with Borderline Personality Disorder clearly lacks the social/emotional skills to fulfill these needs in healthier ways.
