Borderline Personality Disorder

Borderline personality disorder (BPD) is in Cluster B, but I didn’t discuss it in my Cluster B post because I think BPD deserves a post of its own. People with BPD have high impulsivity, drastic mood swings, terror of abandonment, and extremely volatile relationships. Such individuals also have self-images that vary significantly from one moment to the next.

Relationships with people with BPD can be very difficult, since these individuals have intense fear of being abandoned. They also have black-and-white thinking. Their loved ones tend to be either placed on an ivory tower or (with only small provocation) viewed a hateful, evil person. This is often seen in relationships with therapists, parents, and significant others. A person with BPD may feel an intense attachment to her therapist, to the point of crossing personal boundaries, and then feel abandoned and hateful when the therapist tries to set clearer boundaries. People with BPD often respond to environmental stimulus in extreme ways, not understanding or caring what the repercussions of their responses might be. In the example of the therapist, a patient who feels abandoned might become violent, verbally abusing the therapist or attacking her physically.

People with BPD often self-harm, and make multiple attempts at suicide. Often, the attempts at suicide can be viewed as a manipulative attempt to get attention, though sometimes the suicide is completed. (After all, the more often someone attempts, the more likely it is that completion will eventually happen.) Patients with BPD can also experience psychotic or dissociative symptoms. They might have hallucinations or paranoia.

BPD often occurs with other disorders – bipolar disorder is very common. I imagine this has a lot to do with the mood swings, impulsivity, and psychotic and dissociative symptoms. As I’ve said in previous posts, I have been diagnosed with both bipolar disorder II and BPD. I am still very skeptical of the BPD diagnosis, because all of my symptoms that fit in the BPD category can be explained by my bipolar disorder – and I don’t have the characteristic difficulty with relationships and fear of abandonment which are so strongly associated with BPD.

Another disorder that often occurs with BPD is PTSD. This is most likely because people with BPD have often gone through traumatic experiences such as sexual, physical, or emotional abuse as a child.

In order to be diagnosed with BPD, an individual must have five or more of the following traits: 1) frantic efforts to avoid real or imagined abandonment; 2) a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation; 3) identity disturbance – markedly and persistently unstable self-image or sense of self; 4) impulsivity in at least two areas that are potentially self damaging – spending, sex, substance abuse, reckless driving, binge eating; 5) recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior; 6) Affective instability due to a marked reactivity of mood – intense dysphoria, irritability, or anxiety; 7) chronic feelings of emptiness; 8) inappropriate, intense anger or difficulty controlling anger; 9) transient, stress-related paranoid ideation or severe dissociative symptoms.

I have a former friend who has been diagnosed with BPD. She experienced most of these symptoms. One incident that really sticks out in my mind is that when we were going on a distance drive from city-to-city, we stopped at a truck stop along the way. She went into the bathroom, and I stepped into the book shop. When she found me she was frantic – she’d thought I’d abandoned her in the middle of nowhere and that she’d have no way of getting home. At the time I didn’t understand the symptoms of BPD, and I was shocked at her attack. I mean, why on earth would I abandon her in the middle of nowhere? Especially for no reason at all? I told this story to a BPD guest speaker for our class. She laughed and said that her best friend will hop behind an aisle while shopping and she’ll freak out and think he left her. Even though he’s done this many times, she still freaks out every time.

Unfortunately I lost my friend who had BPD. As I said, at the time I didn’t understand BPD. She was having a particularly hard time with her mental illness at the same time that I was having a particularly hard time with my own. We got into fight after fight after fight. Then one day she invited me to a party. I refused – I was isolating because I was very depressed. She decided that I had decided to “friend dump” her and she friend dumped me first. I’ve made several attempts to rekindle the relationship, but it is unfortunately dead.

That brings me to a point that I think is very important. BPD is highly stigmatized in our society. It’s even highly stigmatized among mental health workers – many of whom won’t take more than one BPD patient at a time. There are people who’ll say you should never be friends with someone who had BPD. I think this stigma is tragic. Every person with BPD that I have met was a wonderful person despite their problems. By understanding the symptoms of BPD, and by talking to them about how we should respond when the affected person is in a “mood,” we can have a healthy and wonderful relationship with someone who has BPD.

Personality Disorders – Cluster C

As mentioned in my opening post about personality disorders, personality disorders are split into three clusters -A, B, and C. This post will discuss cluster C. People with these disorders tend to be anxious and fearful.

Avoidant Personality Disorder is characterized by extreme social inhibition and introversion, which lead to few friends and a tendency to avoid social interactions. Unlike schizoid personalities, people with avoidant personality disorder want to have friends, but they are too afraid of rejection to attempt social interaction. They do not enjoy being alone, and are often bored. They generally have low self-esteem and high self-consciousness.

In order to be diagnosed with avoidant personality disorder, the individual must have four or more of the following characteristics, which create clinically significant problems in functioning: 1) avoids occupations that involve interpersonal contact; 2) unwilling to get involved with people unless certain of being liked; 3) shows restraint within intimate relationships for fear of being shamed or ridiculed; 4) preoccupied with criticism and rejection; 5) inhibited in new interpersonal situations; 6) views self as socially inept, unappealing, and inferior; 7) does not take personal risks or engage in new activities for fear of embarrassment.

Dependent personality disorder is characterized by extreme need to be taken care of. They tend to find one person to cling to, and they ask that person for advice on everyday decisions. They are terrified of separation from the person they are dependent upon. They sacrifice their own needs in order to please their chosen person, and often agree to do unpleasant things. They often remain in physically and emotionally abusive relationships. When their relationship is broken off, they desperately seek another person immediately, and often choose an inappropriate partner because of their fear that they are unable to take care of themselves.

In order to be diagnosed with dependent personality disorder, the individual must have five or more of the following traits, leading to clinically significant impairment of function: 1) difficulty making everyday decisions without excessive advice; 2) needs others to assume responsibility for most major areas of life; 3) has difficulty disagreeing with others; 4) has difficulty initiating projects or of doing things alone; 5) goes to excessive lengths to obtain nurturance and support of others; 6) feels uncomfortable or helpless when alone; 7) urgently seeks another relationship when his source of care is broken off; 8) is terrified of being left alone to take care of himself.

I met someone like this at a party once. He asked the entire group if anyone wanted to go wine tasting with a “bunch” of friends the next weekend, and I agreed. Within a day, he was asking me what to wear, how much money he should bring, and how early I thought we should be. He also told me that his wife had made him convert to Lutheran, and he felt extreme guilt over his conversion and wanted to be Catholic again – but he felt uncomfortable going to Mass alone. I naively volunteered to go to Mass with him a few times until he got used to the new church. “A few times” ended up to be every week. He began depending on me for every small decision in his life. Wanted to be around me every day. Said that he couldn’t eat alone and couldn’t exercise alone, so: could I come over and do those things with him? I was unemployed at the time (lots of time) and have an overly agreeable personality, so I got stuck helping him out way too much. I kept telling him I wasn’t interested in an intimate relationship, but he seemed not to understand this concept. (That may have been my fault for helping him out so much.)

Finally, I got sick of him and said that I couldn’t spend that much time helping him. He needed to learn to be independent. I even suggested that he had dependent personality disorder and ought to seek help. That was mean, perhaps, but I was annoyed. It was a sign of his dysfunctional inability to disagree that he agreed I was right: he must have dependent personality disorder.

Anyway, dependent personality disorder is one of the disorders that will be dropped if diagnosis switches over to the dimensional rather than cluster approach. Which I think is unfortunate since I’ve met someone who clearly has those features.

People with obsessive-compulsive personality disorder are the type of people that Freud would call “anally retentive.” They have an incredible need for symmetry, order, and perfection. They have specific rules and schedules and get very upset when those rules and schedules are broken by themselves or others. They tend to be dysfunctional because they are so obsessed with perfectionism that they aren’t able to finish projects. Unlike people with obsessive-compulsive disorder, they do not have true compulsive rituals like excessively washing hands.

In order to be diagnosed with obsessive-compulsive personality disorder, an individual must have at least four of the following traits, which cause clinically significant impairment of function: 1) preoccupation with details, rules, lists, order, organization, or schedules; 2) perfectionism that interferes with task completion; 3) excessively devoted to work and productivity to the exclusion of leisure activities; 4) overconscientious, scrupulous, and inflexible about matters of morality, ethics, or values; 5) unable to discard worn-out or worthless objects even when they have no sentimental value; 6) reluctant to delegate tasks or to work with others unless they follow his instructions perfectly; 7) has miserly spending style towards self or others; 8) shows rigidity and stubbornness.

What do you know? I know someone like this, too! But I won’t discuss him on my blog. 🙂 Some of my readers know who he is, though.

Personality Disorders – Cluster B

As mentioned in my opening post about personality disorders, personality disorders are split into three clusters -A, B, and C. This post will discuss cluster B. People with these disorders tend to be dramatic, emotional, and erratic.

Patients with histrionic personality disorder are characterized by self-dramatization, over-concern with attractiveness, tendency to irritability, and temper outbursts if attention-seeking is frustrated. These patients often manipulate their partners with seductive behavior, but they are also tend to be very dependent on the partners’ attention. They are generally considered self-centered, vain, shallow, and insincere. These traits are much more commonly seen in women than in men – probably because many of the characteristics (like over-concern with appearance) tend to be “women’s traits.” In fact, some argue that histrionic personality disorder is just another form of anti-social personality disorder, which is much more prevalent in men.

In order to be diagnosed with histrionic personality disorder, the patient must have 5 or more of the following traits: 1) she is uncomfortable in situations in which she is not the center of attention; 2) her interactions with others are often characterized by inappropriate sexually seductive or provocative behaviors; 3) she displays rapidly shifting and shallow expression of emotions; 4) she consistently uses physical appearance to draw attention to herself; 5) she has a style of speech that is excessively impressionistic and lacking in detail; 6) she shows self-dramatization, theatricality, and exaggerated expression of emotion; 7) she is suggestible (i.e. easily influenced by others or circumstances); 8) she considers relationships to be more intimate than they actually are.

This is one of the personality disorders that will be dispensed with if the next DSM moves towards a dimensional model of diagnosis, as mentioned in my earlier post.

Narcissistic personality disorder is characterized by grandiosity, preoccupation with receiving attention, self-promoting, and lack of empathy. There are two types: grandiosity and vulnerable narcissism. In the former, the patient is convinced of their superiority; in the latter the patient expresses superiority defensively due to a low self-esteem. Narcissistic personality disorder is observed more often in men than in women.

In order to be diagnosed with narcissistic personality disorder, the patient must meet five or more of the following traits: 1) he has a grandiose sense of self-importance (exaggerates achievements and talents, expects to be recognized as superior); 2) he is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love; 3) he believes that he is “special” and unique and can only be understood by, or should associate with, other special people; 4) he requires excessive admiration; 5) he has a sense of entitlement; 6) he is interpersonally exploitative; 7) he lacks empathy and is unwilling to recognize or identify with the feelings or needs of others; 8) he is often envious of others or believes that others are envious of him; 9) he shows arrogant, haughty behaviors.

Now, I doubt my ex-boyfriend had a personality disorder, but he did have quite a few of these traits – possibly exacerbated by a lifetime of alcoholism which he had only recently given up when I’d met him. In fact, at one point in our relationship, he went to a neurologist to be checked for long-term side-effects of a past concussion, and he returned with a psychological assessment which said he had “narcissistic personality traits.” At the time, I had laughed it off, but later I began to see it.

This guy thought that he was incredibly smart, good looking, and absolutely amazing at his job. He was always bragging about the quality of his work; however, I saw some of his work a couple of times and found it lacking (which I didn’t say, of course). He was always talking about the future – how he had so many offers for jobs (he was unemployed) and how he’d be making well over $300,0000 a year in no time. He surrounded himself with people that he saw as superior (yes, that includes myself – he was always bragging to everyone about how smart and beautiful I was. It was rather embarrassing and over-the-top.) He also showed a surprising lack of empathy – he felt that anxiety was a sign of weakness in others, but when he had anxiety attacks he felt it was uncontrollable rather than a weakness.

Narcissistic personality disorder is one of the disorders that would be dropped if the diagnosis switched to a dimensional rather than cluster approach.

Because there is a lot of public interest in borderline personality disorder and antisocial / psychopathy, I will mention those Cluster B disorders in another post.

Personality Disorders – Cluster A

As mentioned in my opening post about personality disorders, personality disorders are split into three clusters: A, B, and C. This post will discuss the cluster A personality disorders. Cluster A disorders are characterized by distrust, suspiciousness, and social detachment. Often, people with cluster A personality disorders are considered eccentric or odd.

The characteristic traits of paranoid personality disorder are suspiciousness and mistrust of others, tendency to see oneself as blameless, and tendency to be on guard for perceived attacks by others. The disorder develops in early adulthood. To be diagnosed, a person must exhibit 4 or more of 7 traits: 1) he suspects, without sufficient basis, that others are exploiting, harming, or deceiving him; 2) he is preoccupied with unjustified doubts about the loyalty or trustworthiness of friends or associates; 3) he is reluctant to confide in others because of unwarranted fear that the information will be used maliciously against him; 4) he reads hidden demeaning or threatening meanings into benign remarks or events; 5) he persistently bears grudges; 6) he perceives attacks on his character or reputation that are not apparent to others and is quick to react angrily 7) he has recurrent suspicions, without justification, regarding fidelity of spouse or partner.

Of course, I am unqualified to diagnose anyone with a personality disorder, but I think real-life stories are helpful.

When I worked in retail, there was a guy that I had a crush on. We had been “friends” for almost a year, and I figured it was ok to tell him I liked him. He freaked out and said that I’d betrayed him (because he wasn’t ready to date anyone due to a bad experience in the past).

He soon became incredibly paranoid. He accused me to the manager first of stalking him within the store, then of calling his phone number just to hear the sound of his voice (mind you, this guy never handed his phone number out to anyone, so he was basically accusing me of sneaking into the office and illicitly looking up his number), and finally, he accused me of placing a kilo of marijuana near his car. (Though he couldn’t produce said kilo for evidence.)

Looking back, I realized his behavior had been odd all along. He was huge on conspiracy theory; stockpiled guns; thought everyone was out to get him; didn’t tell anyone where he lived, what his phone number was, or any personal details about his past; and he accused me of being nasty and demeaning when I made a casual comment “Oh, you’ve already started Christmas shopping? Seems a bit early.” And boy could he hold a grudge.

Since then, I’ve wondered what happened to this guy. He was really a sweet, caring person. I worry about his health and safety, since his paranoia clearly had a huge negative impact on his life.

This is one of the personality disorders that would be abolished if the next DSM adopts a dimensional approach as discussed in my previous post. I wonder what category these traits would fall into then?

Schizoid personality disorder is characterized by impaired social relationships and low desire to form attachments to others. To be diagnosed with schizoid personality disorder, a patient must have 4 of the following 7 traits: 1) he neither desires nor enjoys close relationships, including being part of a family; 2) he almost always chooses solitary activities; 3) he has little, if any, interest in having sexual experiences with another person; 4) he takes pleasure in few, if any, activities; 5) he lacks close friends or confidants other than first-degree relatives; 6) he appears indifferent to the praise or criticism of others; 7) he shows emotional coldness, detachment, or flattened affectivity.

This is another personality disorder that would disappear with the dimensional approach.

People with schizotypal personality disorder are also loners. People with scizotypal personality disorder tend to have superstitious beliefs, and some experience psychotic symptoms like believing they have magical powers. They can also be paranoid, have distorted speech, or see special meaning in ordinary objects or events. Schizotypal personality disorder is thought to be related to schizophrenia – perhaps a less severe manifestation or a precursor to schizophrenia.

In order to be diagnosed with schizotypal personality disorder, a patient must have five or more of the following traits: 1) he has ideas of reference (believing innocuous events or objects have strong personal meaning); 2) he almost always chooses solitary activities; 3) he has unusual perceptual experiences (mild hallucinations); 4) he has odd thinking and speech (e.g. vague, circumstantial, metaphorical, overelaborate, or stereotyped); 5) he exhibits suspiciousness or paranoid ideation; 6) he has inappropriate or constricted affect; 7) his behavior or appearance is odd or eccentric; 8) he has a lack of close friends or confidants other than first-degree relatives; 9) he has excessive social anxiety.

This is the only cluster A personality disorder that would not be lost if we switched to the dimensional approach of diagnosis.

Personality Disorders – Clusters and Dimensions

Personality disorders are a difficult topic for me. For one thing, they are highly stigmatized. And I think the term “personality disorder” encourages that stigma by suggesting that there is something terribly wrong with a person’s identity, rather than implying that people with these disorders respond to the world in a highly ineffective manner that creates problems for themselves and others. In fact, Butcher describes “personality disorder” in his textbook Abnormal Psychology as: characterized by “chronic interpersonal difficulties and problems with one’s identity or sense of self.” This description is good as long as we accept that the “problem with one’s identity” is that one’s self-esteem and view of one’s relationships with others is unstable.

Everybody exhibits some dysfunctional beliefs and behaviors, but they should not be diagnosed with a personality disorder unless the behavior is pervasive and inflexible, and causes “clinically significant” distress or impairment in functioning. People with personality disorders generally cause just as many problems for others as they do in their own lives. Most do not recognize the dysfunction in their own thoughts or behaviors; therefore, it is often friends, family, or the law that force people with personality disorders to seek treatment.

Personality disorders are grouped into three clusters:

Cluster A includes paranoid, schizoid, and schizotypal personality disorders. People with cluster A disorders tend to be suspicious, paranoid, and/or withdrawn.

Cluster B includes histrionic, narcissistic, antisocial, and borderline personality disorders. People with these disorders have a tendency towards drama, emotionality, and erratic behavior.

Cluster C includes avoidant, dependent, and obsessive-compulsive personality disorders. These people tend to experience anxiety and fear.

Most personality disorders are not caused by a few traumatic events, but by a build-up of many stressors throughout life – like childhood abuse, neglect, or criminal behavior in parents. A child’s natural temperament may also have a strong impact on the development of a personality disorder later in life.

Compared to the other mental illnesses, there is little research on personality disorders. This is because people with personality disorders often do not feel there is anything wrong with themselves, or if they realize there is something wrong, they have less-than-helpful personality characteristics (such as lack of empathy or withdrawn social interaction). Another difficulty in studying people with personality disorders is the large amount of misdiagnosing that occurs. The criteria for diagnosis are more influenced by a clinician’s judgement than are the criteria for other mental illnesses.

Due to these difficulties in diagnosis of personality disorders, much work has been done in developing dimensional systems as an alternative to the cluster model. A dimensional model would rate a person on a set of personality traits, thus providing an overall behavioral pattern. Such an analysis would theoretically be more empirical than the cluster model. Such changes were proposed for the DSM-5, but they were deemed too complex for rushed clinicians and were shunted off into the “Emerging Measures and Models” section.

One popular dimensional approach is the five-factor model. According to proponents of the Big Five, everyone’s personalities can be defined by our strengths and weaknesses in five traits: neuroticism, openness to experience, extraversion, agreeableness, and conscientiousness. Each of these traits are further separated into sub-traits.

Neuroticism: anxiety, anger/hostility, depression, self-consciousness, impulsiveness, and vulnerability.

Extraversion: warmth, assertiveness, gregariousness, activity, excitement seeking, and positive emotions.

Openness to experience: fantasy, aesthetics, feelings, actions, ideas, and values.

Agreeableness: trust, straightforwardness, altruism, compliance, modesty, and tender mindedness.

Conscientiousness: competence, order, dutifulness, achievement striving, self-discipline, and deliberation.

Using this model, when a patient comes in for analysis, she would be rated high or low for each of the factors. The overall pattern (combined with knowledge of whether the individual experiences clinically significant distress) can be used to diagnose a personality disorder. Using the five-factor model, only six of the personality disorders would remain: borderline, antisocial, schizotypal, narcissistic, obsessive-compulsive, and avoidant. The others (paranoid, schizoid, histrionic, and dependent personality disorders) would be dropped.

Hopefully much research will go into developing a more empirical approach to diagnosis of personality disorders, for I feel that patients would benefit greatly from treatments that target specific dysfunctional traits instead of a generalized “personality disorder.”

If you’re interested, there are quite a few Big Five tests on the internet. I just took the Truity test. If you take it, you don’t have to create an account. There’s a “skip” option. My scores were:

Open to experience: 80%

Conscientiousness: 85%

Extraversion: 57.5%

Agreeableness: 92.5%

Neuroticism: 52.5%

Apparently, a score of 50% is considered “average person.” This test was fun and gives you an idea of what types of questions might be asked with a dimensional approach to diagnosis; however, it was certainly too short and silly to accurately diagnose a personality disorder. I’m surprised I didn’t get a higher score on neuroticism because of my bipolar disorder. Hopefully the test developed by clinical psychologists is much more extensive and precise. 🙂
