PDF Summary:I Hate You--Don't Leave Me, by Jerold J. Kreisman and Hal Straus

Borderline Personality Disorder (BPD) affects millions of people, yet it remains widely misunderstood—even among mental health professionals. Those with BPD often struggle with intense emotions, unstable relationships, impulsive behaviors, and a fragmented sense of self. These symptoms can lead to cycles of crisis and despair, affecting not only the person with BPD but also their loved ones.

In I Hate You--Don't Leave Me, Jerold J. Kreisman and Hal Straus explain what BPD is, where it comes from, and how it manifests in daily life. You'll learn about the biological and developmental roots of BPD, how it's diagnosed, and what treatment options are available. The authors also provide strategies for managing crises and improving communication with those who have BPD, offering practical guidance for both patients and the people who support them.

In the separation-individuation stage, between ages two and three, children begin to detach from their main caregiver and form a unique sense of self. It's vital for future mental well-being that the child can successfully move through this developmental stage. Throughout the entire process of separation-individuation, the child starts to define the limits between themselves and others, which is made more complex by two main conflicts—the wish for independence versus wanting intimacy and dependence, and fear of being overwhelmed versus fear of being left behind.

(Shortform note: The separation-individuation stage is important for later mental well-being because it teaches the child that they can be independent without losing the comfort and protection of their caregiver. When a caregiver encourages the child to explore the world and then welcomes them back, the child learns that they can be independent and still have a safe place to return to. This process helps the child’s brain understand that they can be independent without losing the comfort and protection of their caregiver.)

Contextual Factors and Prognosis

Kreisman and Straus claim that societal factors influence BPD. It’s a pathological reaction to the stresses of modern society. The breakdown of traditional family structures, increasing divorce rates, and the frequency of substance abuse and child neglect have all created a feeling of instability and insecurity. Economic uncertainty, political violence, and weakened group loyalties have further eroded our sense of belonging and identity. These societal factors have led to a reduced feeling of identity validation, declining social connections, solitude, loneliness, and impulsivity. The lack of stabilizing forces in our lives has made it difficult for us to feel in control and familiar, leading to many unhealthy patterns.

BPD in Non-Western Countries

The authors’ view of BPD as a pathological reaction to modern society may not hold up in non-Western countries. Peter Tyrer, Geoffrey M. Reed, and Michael J. Crawford argue that BPD is not limited to Western or highly industrialized societies. They point out that epidemiological and clinical research over the past three decades has shown that personality disorders, including BPD, are prevalent in diverse cultural and regional settings. When comparable diagnostic methods are used, similar patterns of prevalence, comorbidity, and impairment are found across different societies. This suggests that BPD is not simply a culture-specific reaction to modern societal stressors but rather reflects enduring disturbances in personality functioning that can manifest in various cultural contexts.

However, the outlook for BPD has improved beyond earlier expectations. In the 1980s, people believed that personality disorders were stable and didn't change over time. It’s now widely recognized that personality characteristics can shift at any stage in life.

(Shortform note: This shift in thinking about personality disorders was influenced by a broader change in how psychologists viewed personality in general. In the 1980s, researchers began conducting large-scale studies that tracked people's personalities over many years. These studies showed that people's personalities often change in predictable ways as they age, challenging the old belief that personality stays the same throughout life.)

Research tracking people with BPD over time has shown notable progress. In these studies, as many as two-thirds of individuals stopped exhibiting the core symptoms of BPD after a decade. Patients improved whether or not they received treatment, although those who did recovered more quickly. The majority of patients continued with their treatment, and relapses decreased over time. However, some patients persisted in having difficulty with interpersonal skills, which negatively impacted their work and personal connections. This suggests that more acute symptoms of BPD—like suicidal thoughts or self-harming actions, destructive impulsivity, and quasi-psychotic thinking—respond more quickly to treatment or time than enduring symptoms, like abandonment fears, feelings of emptiness, and dependency. Those who overcome the illness demonstrate improved ability to trust and form fulfilling relationships.

Limitations of BPD Prognosis

The authors’ optimistic outlook for people with BPD is based on studies that excluded people with BPD who also had major psychotic disorders or significant cognitive impairment. Therefore, the positive prognosis may not apply to these subgroups. People with BPD who also have psychotic disorders like schizophrenia or schizoaffective disorder may have a more complex clinical picture, with symptoms that are more severe and persistent. The presence of psychotic symptoms can complicate treatment and may lead to a less favorable long-term outcome. Similarly, people with BPD who have significant cognitive impairment may face additional challenges in treatment, such as difficulties with learning new coping skills or engaging in psychotherapy. This can also impact their long-term prognosis, potentially leading to a slower or less complete recovery.

Managing Borderline Personality Disorder: Identifying, Treating, and Intervening in Crises

Next, we'll discuss how BPD is diagnosed and managed.

Diagnosing and Assessing BPD

According to Kreisman and Straus, BPD is a common but often misunderstood condition. It’s estimated that 3-6% of the US population has BPD, and 15-25% of patients who seek psychiatric treatment receive this diagnosis. However, BPD is unfamiliar to most people and is often misunderstood by mental health professionals. The diagnosis is fairly recent, and for many years, "borderline" served as a broad category for patients who didn't fit other, more recognized diagnoses. The label "borderline" originated in the 1930s, but the condition wasn't clearly defined until the 1970s.

(Shortform note: Recent studies support the authors’ view of BPD as a common but often misunderstood condition. In a 2020 study, researchers found that BPD affects 1.6% of adults worldwide, with a range of 0.7% to 2.7% across different countries. This suggests that BPD is a significant mental health issue worldwide, affecting a small but meaningful portion of the population. The relatively narrow range of prevalence rates across countries also suggests that the identification of BPD has become more consistent over time.)

In 1980, the third edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-III) was the first to include the diagnosis of Borderline Personality Disorder. It's now formally acknowledged to be a significant psychological issue in the U.S. BPD is frequently misdiagnosed as other conditions, including depression, anxiety, bipolar disorder, schizophrenia, or ADHD. It can also coexist with other conditions, such as depression, anxiety, bipolar disorder, schizophrenia, somatization disorder, dissociative identity disorder, ADHD, PTSD, alcoholism, substance use disorder, disordered eating, phobias, OCD, hysteria, antisocial personality disorder, and other personality conditions. Around 90% of people who have BPD also have another significant psychiatric diagnosis. Additionally, BPD frequently links to major medical conditions, particularly in women. This encompasses persistent head pain and other aches, joint inflammation, and illnesses affecting the heart and blood vessels, digestive tract, urinary tract, lungs, liver, immune system, and cancer.

BPD and Medical Illnesses

Frances R. Frankenburg and Mary C. Zanarini conducted a study to determine whether people with BPD have more medical illnesses than people with other psychiatric conditions. They found that people with BPD had more medical illnesses, even after accounting for other psychiatric conditions. This suggests that people with BPD are more vulnerable to medical illnesses, not just that they have more psychiatric diagnoses. The study also found that people with BPD used more health-care services than people with other psychiatric conditions. This suggests that people with BPD have more medical needs, not just that they have more psychiatric diagnoses.

Next, we’ll discuss BPD’s clinical presentation and explore some diagnostic approaches.

Clinical Presentation

According to Kreisman and Straus, BPD is linked to self-harming actions, including substance abuse, disordered eating, and compulsions. Over half of people with BPD abuse substances, and about one-third of those diagnosed with substance abuse disorders also have BPD. Substance abuse could be a means of managing symptoms, coping with loneliness, or feeling connected to others. BPD is linked to eating disorders like anorexia and bulimia. People with eating disorders often struggle with their self-concept and feel empty inside. They may engage in self-destructive behaviors like starving themselves or bingeing and vomiting to feel more in control.

(Shortform note: The clustering of self-harming behaviors is important because it suggests a more entrenched pattern of self-harm that may require more intensive treatment. For example, people with BPD and substance abuse disorders are more likely to have a history of suicide attempts and to have been hospitalized for psychiatric reasons. Similarly, people with BPD and eating disorders are more likely to have a history of self-harm and to have been hospitalized for psychiatric reasons. This means that people with BPD and co-occurring disorders may need more intensive treatment than people with BPD or the co-occurring disorder alone. For example, people with BPD and substance abuse disorders may need to be treated for both disorders simultaneously, and people with BPD and eating disorders may need to be treated for both disorders in a specific order.)

Additionally, BPD is linked to compulsive behaviors like gambling, shoplifting, and promiscuity. These actions might help them seek excitement, punish themselves, or feel something when they feel numb. Those who have BPD might also be drawn to cults because they provide a sense of belonging, acceptance, and a clear leader to follow.

Impulsive Behaviors in BPD

Lieb et al. note that BPD is characterized by a pattern of affective instability, disturbed interpersonal relationships, identity disturbance, and impulsive, self-damaging behaviors. They note that these impulsive behaviors can include excessive spending, substance misuse, unsafe sexual activity, binge eating, or reckless driving. However, the authors suggest that these behaviors are best understood as non-specific manifestations of broader behavioral dysregulation rather than unique or defining markers of the disorder. They also don’t mention any specific tendency for people with BPD to join cults.

Kreisman and Straus also note that BPD has a strong link to a high risk of suicide. Up to 70% of people with BPD make suicide attempts, and around 10% of these are successful—almost a thousandfold increase over the general population rate.

The likelihood of suicide among those with BPD persists throughout life and may even increase with age. Having a past of self-injury is the biggest predictor of suicide. Men with BPD are more likely to die by suicide than women. People with BPD who also have depression, bipolar disorder, or substance abuse problems are more likely to die by suicide. The risk is also higher in people who have BPD and were abused as children. Signs of an unclear sense of self, emptiness, and abandonment fears are the most strongly linked to suicide attempts.

Creating a Safety Plan

The patterns described here can help you create a safety plan for yourself or a loved one with BPD. In Loving Someone with Suicidal Thoughts, Stacey Freedenthal explains that creating a safety plan before a crisis occurs is one of the most helpful things you can do when suicidal thoughts are present. A safety plan is a written document that outlines specific steps to take when suicidal thoughts or behaviors arise. It should include:

• Warning signs: List the specific thoughts, feelings, or behaviors that indicate a crisis is building. This might include increased self-harm urges, feelings of emptiness, or intense fear of abandonment.
• Coping strategies: Identify activities or techniques that help manage distress, such as deep breathing, listening to music, or engaging in a favorite hobby.
• Support network: List people to contact when feeling unsafe, such as friends, family members, or a therapist.
• Professional help: Include contact information for mental health professionals, crisis hotlines, and emergency services. Freedenthal emphasizes that the safety plan should be created collaboratively with the person experiencing suicidal thoughts and, ideally, with input from a mental health professional.

Diagnostic Approaches

Diagnosing BPD is challenging due to symptom overlap with other disorders. Kreisman and Straus explain that BPD is among the ten personality disorders included in the DSM-5. Personality disorders involve a set of emerging characteristics that stand out in a person's behavior. These characteristics are usually fairly rigid and lead to unhealthy ways of seeing the world, acting, and interacting with others.

Diagnosing BPD is challenging because its symptoms often mimic those of other disorders, such as schizophrenia, anxiety, bipolar disorder, and ADHD. BPD frequently co-occurs with other conditions, leading clinicians to sometimes overlook BPD as a significant factor in assessing a patient. As a result, individuals with BPD often undergo assessments at various hospitals and clinics and receive different diagnostic labels. Abandonment fears and identity disturbance are the most effective criteria to differentiate borderline personality disorder from bipolar disorder.

Research on Differentiating BPD and Bipolar Disorder

Joel Paris, a psychiatrist and professor at McGill University, has conducted research comparing patients with BPD and bipolar disorder. He found that disturbances in attachment patterns and self-definition are more effective in distinguishing BPD from bipolar disorder than the symptom clusters associated with bipolar disorder. This finding supports Kreisman and Straus's assertion that abandonment fears and identity disturbance are key criteria for differentiating BPD from bipolar disorder. Paris's research suggests that clinicians should prioritize assessing these features when evaluating patients with complex mood and personality symptoms.

The DSM-5 uses a categorical approach to diagnose BPD, but some suggest a dimensional model. The DSM-5 lists nine criteria for diagnosing BPD; a person must meet five of them to be diagnosed. However, the categorical method has been criticized for being too rigid. If someone with BPD loses one symptom, they no longer meet the criteria for diagnosis, even if they still have the disorder.

Some suggest a spectrum-based method, which would acknowledge that BPD exists on a spectrum. The dimensional method would weigh the criteria differently, depending on which signs are more common and long-lasting. This method would additionally assess how effectively someone can function in daily life.

Choosing a Diagnostic Approach

When deciding whether to use the categorical approach or a dimensional method, consider which method has more empirical support for predicting the clinical outcomes you’re most interested in. For example, if you’re trying to predict the likelihood of self-harm, you might favor the dimensional approach if it has stronger evidence for predicting this outcome. Conversely, if you’re more concerned with predicting treatment response, you might lean toward the categorical approach if it has better predictive validity in this area.

Approaches to Crisis Management and Treatment

When it comes to treatment, Kreisman and Straus note that approaches based on cognitive and behavioral methods focus on altering current thought processes and repetitive actions. These treatments don't focus as much on the past as psychodynamic methods do. Instead, they emphasize problem-solving and are frequently limited in duration.

(Shortform note: Cognitive and behavioral methods are more structured and skills-focused, while psychodynamic methods focus on the emotional meaning of your recurring relationship patterns, including with your therapist. Cognitive and behavioral methods are often more structured and skills-focused, while psychodynamic methods focus on the emotional meaning of your recurring relationship patterns, including with your therapist.)

Meanwhile, exploratory therapy aims to change personality organization. With this method, the therapist gives the patient minimal direct guidance. Instead, they challenge the patient to highlight how certain behaviors are destructive and to analyze unconscious factors that might be driving them, with the aim of eliminating them.

In the initial phase of treatment, the main objectives are to reduce self-harming behaviors that disrupt therapy, reinforce the patient's dedication to change, and build a dependable, trustful bond between doctor and patient. The subsequent phases highlight the importance of developing an independent, self-accepting identity, building stable and trusting connections, and adapting to solitude and experiencing separations (even from your therapist).

Structural Theories of Personality

The idea of changing “personality organization” through exploratory therapy comes from structural psychoanalytic theories. In Psychoanalytic Diagnosis, Nancy McWilliams explains that structural theories group people into broad levels of personality functioning—such as neurotic, borderline, and psychotic—based on how integrated their sense of self is, how they relate to others, and how they defend against anxiety. The goal of exploratory therapy, from this perspective, is to help someone move toward a more integrated level of functioning. This involves developing a more coherent sense of self, forming more stable relationships, and relying on more flexible coping strategies.

Next, we'll explore the different treatment modalities and crisis intervention strategies for BPD.

Therapeutic Approaches

According to Kreisman and Straus, medications can help manage specific BPD symptoms. Although the FDA has not approved any medications for BPD, doctors often prescribe them off-label to target particular symptoms. The American Psychiatric Association recommends using medications to address clusters of specific symptoms: unstable moods, impulse control issues, and cognitive-perceptual disturbances.

Mood stabilizers like lithium and antiseizure drugs can stabilize mood, lessen anxiety, and manage impulsivity, aggressiveness, irritability, and anger. Neuroleptics (antipsychotics) can help with distrust, dissociation, and a sense of detachment from reality. They can also reduce anger, aggressiveness, anxiety, obsessive thoughts, impulsiveness, and sensitivity in relationships. Anxiolytics (anti-anxiety medications) can help with anxiety, but they might heighten impulsiveness and be addictive. Opiate antagonists can help reduce self-harm. Omega-3s can help reduce aggressive and depressive tendencies. Agents that affect glutamate as a neurotransmitter can help reduce self-injurious behavior.

A More Restrictive Approach to Medication for BPD

The National Institute for Health and Care Excellence (NICE) in the UK takes a more restrictive approach to medication for BPD. They advise against using psychiatric drugs specifically for BPD or its symptoms, such as self-harm, emotional instability, risk-taking, and transient psychotic symptoms. They recommend considering drug treatment, especially sedatives, only for short-term use during a crisis, with a clear time limit of no more than one week. This stance contrasts with the more medication-oriented approach described above, which suggests a broader use of various medications to manage specific BPD symptoms.

Kreisman and Straus add that various psychotherapy methods help treat BPD. However, no single approach has proven to be better than the others. Therapists should tailor treatment methods to the individual needs of patients instead of attempting to use a universal method.

For example, individuals experiencing suicidal ideation or practicing self-mutilation might respond most effectively to cognitive or behavioral strategies. Psychodynamic protocols might be better suited for higher-functioning patients. Budget or time constraints may lead to shorter therapies, while recurring harmful behaviors might necessitate more prolonged and intensive approaches.

Certain therapists adhere strictly to procedures specified in manuals. Others might use a diverse therapy method that integrates different techniques. Patients should comprehend and feel at ease with the clinician's methods.

Outcome Rating Scales

You can use this information by asking your therapist to use outcome rating scales. In The Heart and Soul of Change, the authors explain that outcome rating scales are brief questionnaires that clients complete at the beginning and end of each session. These scales ask clients to rate their overall well-being, the quality of the therapeutic relationship, and their progress toward treatment goals. The authors argue that using these scales can improve therapy outcomes by giving clients a voice in the process and helping therapists adjust their approach based on real-time feedback. They note that the scales take only a minute or two to complete and can help identify when therapy isn’t working so that changes can be made. The authors also suggest that using these scales can help clients feel more empowered and engaged in their own treatment.

Crisis Intervention and Stabilization

In terms of crisis intervention, Kreisman and Straus note that the SET-UP approach is a structured communication method for dealing with BPD crises. It was initially created for medical staff and later adjusted for the relatives and loved ones of people with BPD. It aligns with the aims of official programs implemented by clinicians. SET-UP aims to address urgent situations, improve dialogue, and prevent escalation in disagreements. It aids in managing the overwhelming emotions by providing built-in responses that target deep-seated fears, diffuse borderline eruptions, and avert an escalation into bigger confrontations. It pinpoints unhelpful thoughts and behaviors and collaborates with the borderline person to adjust them.

(Shortform note: A precursor to the SET-UP approach is Marshall Rosenberg’s Nonviolent Communication, which introduces a stepwise conversational script for de-escalating highly charged emotional interactions. Rosenberg’s method, which he explains in his 1999 book, is based on the idea that we can communicate more effectively and compassionately by focusing on four key components: observations, feelings, needs, and requests. By breaking down communication into these components, Rosenberg provides a clear framework for expressing oneself and understanding others without resorting to blame, criticism, or defensiveness. The stepwise nature of Nonviolent Communication (NVC) is particularly effective in de-escalating conflicts because it encourages individuals to slow down and reflect on their own emotions and needs before reacting impulsively. This structured approach helps prevent misunderstandings and reduces the likelihood of emotional outbursts. By teaching individuals to identify and articulate their feelings and needs clearly, NVC fosters a more empathetic and collaborative environment, making it easier to resolve conflicts peacefully and constructively.)

It prioritizes harmful urges and suggests constructive, reasoned ways to handle emotional distress. It stresses understanding yourself and other people and tackles issues related to relationships and faith. It also seeks to change the borderline person's skewed perceptions of themselves and others, addresses their sensitivity to rejection and fears of being abandoned, tackles traumatic or anxiety-inducing circumstances, and fosters mentalization, mindfulness, and the bravery to face difficult realities. It can additionally help those who need brief and regular communication, even outside of emergencies.

(Shortform note: In Psychotherapy for Borderline Personality Disorder, Anthony W. Bateman and Peter Fonagy argue that the key to treating BPD is to help patients develop their ability to reflect on their own and others' thoughts and feelings. They say that this reflective capacity is the engine behind mentalization, mindfulness, and the ability to face painful realities. By encouraging patients to consider what might be going on in their own and others' minds, especially when they're upset, therapists help them build this skill. This approach teaches patients to be curious about their experiences and to consider different possibilities instead of jumping to conclusions.)

SET-UP is a communication framework with three parts: Support, Empathy, and Truth. In addressing harmful actions, crucial choices, or other emergencies, engagement with the person with borderline should incorporate all three aspects equally. This is the main continuous approach to sustaining a productive exchange in the present. The support aspect involves a personal statement using "I" to express concern. The focus is on the speaker's emotions and serves as a personal commitment to attempt to assist.

(Shortform note: In Overcoming Borderline Personality Disorder, Valerie Porr warns that intense, repetitive efforts to rescue a loved one from every emotional emergency can inadvertently reinforce crisis behaviors. Attention and frantic caretaking often function as powerful rewards. Family members need to combine empathy and validation with firm, predictable limits so that they reinforce skillful, non-crisis behavior instead of escalating emergencies. This also protects them from the exhaustion, resentment, and burnout that eventually undermine their capacity to be compassionate and effective.)

Empathy involves recognizing their distress and turbulent emotions by addressing them directly. It should be conveyed in an objective manner with little personal input from the speaker. The emphasis is on the distressing experiences of the person with borderline, not those of the speaker. Truth acknowledges the reality of what's happening and stresses that someone with BPD is responsible for their own life and others’ efforts to assist can’t replace this fundamental obligation. Truth statements recognize that there is a problem and focus on the concrete matter of how to fix it. They need to be communicated neutrally and matter-of-factly, without blame or sadistic punishment. Truth also aims to start considering potential solutions and counter sensations of hopelessness or helplessness.

The Potential Pitfalls of “Truth”

While the authors stress the importance of “Truth” in helping someone with BPD, it’s important to note that this approach can backfire if not handled with care. If the person with BPD feels that their emotions are being dismissed or invalidated, they may perceive the environment as invalidating, which can exacerbate their distress and lead to a crisis. For example, if a person with BPD is expressing intense fear of abandonment and the response is a matter-of-fact statement like, “You know that’s not going to happen,” without first acknowledging and validating their fear, they may feel dismissed and become more agitated. This can lead to a shutdown in communication and a refusal to engage with further help.

Another crisis intervention strategy is hospitalization, which is frequently employed for acute crises. Kreisman and Straus explain that hospitalization provides a structured, supportive environment that helps those with BPD manage their chaotic emotions and behaviors. It also provides a break from highly emotional relationships that can trigger their symptoms. Hospitalization is often used for acute crises, such as suicide attempts, aggressive outbursts, episodes of psychosis, or self-harming behaviors. Insurers typically restrict hospitalizations to several days and only cover the charges when there is a documented danger to self or others.

(Shortform note: The authors’ description of hospitalization for acute crises may be outdated. In the UK, the National Institute for Health and Care Excellence (NICE) has issued new guidelines for managing acute crises in people with BPD. These guidelines recommend that crisis care for people with BPD should be based on an agreed crisis plan, delivered as far as possible by specialist community services (such as crisis resolution and home-treatment teams) in the least restrictive setting. Admission to an acute psychiatric inpatient unit should be considered only when there is significant risk to self or others that cannot be safely managed by these community-based alternatives.)

While a patient is in short-term hospitalization, they undergo a full evaluation of their physical and neurological state. The center prioritizes providing structure, setting limits, support, and fostering a constructive relationship. Treatment concentrates on practical, adaptive responses to turmoil. Career and life skills are assessed. Meetings involving relatives may be initiated. A formal agreement between the individual and the team might strengthen shared expectations and boundaries. Short-term hospitalization aims to address the crises that triggered it and end harmful behaviors. Individual and contextual strengths are recognized and supported. Significant treatment concerns are identified or reassessed, and changes to therapy techniques and medications might be recommended. As the main priority is to get the patient back to the external world swiftly and prevent any setbacks or reliance on the hospital, the planning for discharge and aftercare starts as soon as they are admitted.

(Shortform note: Short-term hospitalization can be a double-edged sword for people with BPD, especially those with a history of trauma. While it offers immediate safety and stabilization, the experience can sometimes be retraumatizing. The Substance Abuse and Mental Health Services Administration (SAMHSA) warns that without realizing it, service providers may retraumatize individuals in their care by replicating the very dynamics that were part of the original trauma. For example, the loss of autonomy, strict routines, and unfamiliar environments in hospitals can mirror past experiences of powerlessness or confinement. This can lead to increased anxiety, distrust of medical professionals, and even avoidance of future treatment. To mitigate these risks, SAMHSA recommends that all behavioral health services adopt trauma-informed care principles. This approach recognizes the widespread impact of trauma and emphasizes safety, trustworthiness, choice, collaboration, and empowerment in all aspects of care. By creating environments that feel safe and respectful, providers can help prevent retraumatization and support more effective healing for people with BPD and trauma histories.)

Extended hospital stays are uncommon and typically available to the extremely affluent or to people with outstanding psychiatric insurance plans. Often, when ongoing long-term care is needed without requiring full-time residency, therapy can proceed in a more flexible setting, like partial hospitalization. Advocates of extended hospital stays acknowledge the risk of becoming more dependent, but they assert that genuine personality transformation might need comprehensive, rigorous treatment in a regulated setting. Reasons for extended hospitalization include consistently low drive, social supports that are insufficient or detrimental, major functional impairments that prevent self-sufficiency or employment, and multiple unsuccessful attempts at outpatient therapy and short hospital stays. In extended hospitalizations, the environment might have less structure.

(Shortform note: While extended hospital stays may be necessary for some people with BPD, they can also be harmful. Psychiatric hospitals are “total institutions,” meaning that they’re isolated from the outside world and have their own rules and routines. This can make it difficult for people to adjust to life outside the hospital, even if their symptoms have improved. For example, people who have spent a long time in a psychiatric hospital may have difficulty finding a job or housing, and they may feel isolated from their friends and family.)

The patient is motivated to take a more active role in their treatment. Beyond present practical matters, the patient and staff investigate previous transference topics and archetypal behavioral patterns. The hospital may serve as a laboratory where the borderline patient pinpoints particular issues and tests out solutions through engagement with the staff and fellow patients. Longer hospitalization builds upon the objectives of short-term care, focusing not just on recognizing dysfunction but also on making changes. The most evident indicators of effective hospital care include improved impulse management, less frequent mood swings, enhanced capacity for trust and relationship-building, a clearer sense of self, and greater frustration tolerance.

(Shortform note: In The Neuroscience of Psychotherapy, Louis Cozolino explains that early relationships shape the organization of neural networks that encode implicit expectations of self and others. These procedural memories form stable interpersonal schemas that are automatically activated in current relationships and repeated as transferential patterns in therapy. Within a safe and attuned therapeutic relationship, these patterns can be brought into awareness, emotionally experienced, and gradually reorganized.)

During a lengthy hospital stay, educational and career goals can be achieved. While moving from the hospital, many patients can start commitments to work or school. It might be possible to finalize adjustments to unhealthful arrangements—like leaving home, divorcing, etc. A significant risk of extended hospitalization is that patients may regress. Day or partial hospital care involves the patient participating in hospital activities for some or most of the day before heading home at night. Partial hospitalization can also take place at night, after one's job or studies, and they might provide sleeping accommodations if no other options are available.

(Shortform note: The National Collaborating Centre for Mental Health (NCCMH) and the National Institute for Health and Care Excellence (NICE) in the UK recommend that people with BPD should only be admitted to inpatient care in cases of crisis, and that these stays should be brief. This is in line with the UK’s community-based approach to mental health care, which aims to keep people out of hospitals and in their communities as much as possible. The authors argue that long-term or partial hospitalization can be counterproductive for people with BPD, as it can reinforce their dependence on others and prevent them from developing the skills they need to manage their emotions and relationships.)

This strategy suits people who aren't a risk to themselves or others and need less oversight. This method lets individuals with BPD remain part of the hospital program and gain from the structured and intense environment while still living independently. Partial hospitalization generally causes less dependency compared to long-term hospital stays. Partial hospital care is generally less costly than conventional inpatient treatment, so it's often chosen for budget reasons. This approach may be beneficial for individuals diagnosed with BPD who need more comprehensive care without constant supervision, risk major regression from being hospitalized, are moving from a hospital setting to everyday life, have to keep up with work or studies while needing hospital care, or have significant financial constraints. The therapeutic setting and goals at the hospital resemble those of the corresponding inpatient program.

Partial Hospitalization and the Problem of Compartmentalization

A potential problem with partial hospitalization is that it can reinforce the feeling of living in two worlds. In Psychotherapy for Borderline Personality Disorder, Anthony Bateman and Peter Fonagy argue that for individuals with BPD, the effectiveness of treatment depends on establishing a stable, coherent therapeutic frame that is firmly linked to the person’s everyday interpersonal world. If the treatment context is experienced as a separate, compartmentalized reality that can’t be integrated with the emotionally charged situations of ordinary life, then any increase in mentalizing and affect regulation achieved in sessions will remain fragile and tends to break down when the individual returns to their usual relational environment, reinforcing experiences of fragmentation and living in “different selves” across different contexts.
