Difficult patient, or something else? A review of personality disorders

These clues may suggest a personality disorder

If you find that encounters with a particular patient are growing increasingly difficult, consider whether the following behaviors, attitudes, and patterns of thinking are coming into play. If they are, you may want to consider using a screening tool, which we’ll discuss in a moment.

❚  Clues to cluster A disorders

• The patient has no peer relationships outside immediate family.
• The patient almost always chooses solitary activities for work and personal enjoyment.

❚  Cluster B clues

• Hypersensitivity to treatment disagreements or cancelled appointments are common (and likely experienced as rejection).
• Mood changes occur very quickly, even during a single visit.
• There is a history of many failed relationships with providers and others.
• The patient will describe an individual as both “wonderful” and “terrible” (ie, splitting) and may do so during the course of one visit.
• The patient may also split groups (eg, medical staff) by affective extremes (eg, adoration and hatred).
• The patient may hint at suicide or acts of self-harm.⁷

❚  Cluster C clues

• There is an excessive dependency on family, friends, or providers.
• Significant anxiety is experienced when the patient has to make an independent decision.
• There is a fear of relationship loss and resultant vulnerability to exploitation or abuse.
• Pervasive perfectionism makes treatment planning or course changes difficult.

• Anxiety and fear are unrelieved despite support and ample information.

Consider these screening tools

Several screening tools for personality disorders can be used to follow up on your initial clinical impressions. We also highly recommend you consider concurrent screening for substance abuse, as addiction is a common comorbidity with personality disorders.

❚ First-line treatment of personality disorders is psychotherapy; medications are mainly used for symptom management.

❚ A sampling of screening tools. The Standardised Assessment of Personality Abbreviated Scale (SAPAS)⁹ is an 8-item measure that correlates well with disorders in clusters A and C.

BPD (cluster B) has many brief scale options, including the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD).¹⁰ This 10-item questionnaire demonstrates sensitivity and specificity for BPD.

The International Personality Disorder Examination (IPDE) includes a 15-minute screening tool to help identify patients who may have any personality disorder, regardless of cluster.¹¹

Improve patient encounters with these Tx pearls

In the family medicine clinic, a collaborative primary care and behavioral health team can be extremely helpful in the diagnosis and management of patients with personality disorders.¹² First-line treatment of these disorders is psychotherapy, whereas medications are mainly used for symptom management. See Black and colleagues’ work for a thorough discussion on psychopharmacology considerations with personality disorders. ¹³

The following tips can help you to improve your interactions with patients who have personality disorders.

❚ Cluster A approaches

• Recommend treatment that respects the patient’s need for relative isolation.¹⁴

• Don’t be personally offended by your patient’s flat or disinterested affect or concrete thinking; don’t let it diminish the emotional support you provide.⁶
• Consult with a health psychologist (who has expertise in physical health conditions, brief treatments, and the medical system) to connect the patient with a long-term therapist. It is better to focus on fundamental changes, rather than employing brief behavioral techniques, for symptom relief. Patients with personality disorders tend to have better outcomes with long-term psychological care.¹⁵

❚  Cluster B approaches

• Set boundaries—eg, specific time limits for visits—and keep them.⁸
• Schedule brief, more frequent, appointments to reduce perceived feelings of abandonment.
• Coordinate plans with the entire clinic team to avoid splitting and blaming.¹⁶
• Avoid providing patients with personal information, as it may provide fodder for splitting behavior. ⁸
• Do not take things personally. Let patients “own” their own distress. These patients often take an emotional toll on the provider.¹⁶
• Engage the help of a health psychologist to reduce burnout and for more long-term continuity of care. A health psychologist who specializes in dialectical behavioral therapy to work on emotion regulation, distress tolerance, and interpersonal effectiveness would be ideal.¹⁷
