Personality Disorders in Primary Care: A Structured Approach to Management presented by Dr. Jadah Johnson

Personality disorders represent a persistent and often under-recognized challenge in primary care. Unlike episodic mental health conditions, these disorders typically present as enduring patterns of interpersonal difficulty, emotional dysregulation, and complex care interactions over time. For many primary care providers, the challenge lies not in assigning a diagnosis, but in managing behaviours that impact therapeutic relationships and care continuity.

In a recent Alethea Learning Session, Dr. Jadah Johnson presented a structured, evidence-informed framework to support primary care providers in recognizing and managing personality disorders, particularly Cluster B presentations, through practical, sustainable strategies.

Reframing the Clinical Challenge

A central theme of the session was the need to move away from diagnosis-focused approaches toward pattern recognition. Personality disorders often emerge through consistent patterns such as:

• Persistent interpersonal conflict
• Emotional responses disproportionate to context
• Rigid or maladaptive coping strategies
• Recurrent crises across settings

Cluster B traits, including borderline, narcissistic, antisocial, and histrionic presentations, are especially relevant in primary care due to their association with high healthcare utilization and complex care dynamics.

Differentiating Cluster B Presentations

Understanding key distinctions can help guide management:

• Borderline Personality Disorder (BPD): Emotional instability, fear of abandonment, impulsivity, and recurrent crises
• Narcissistic Personality Disorder (NPD): Sensitivity to criticism, difficulty with empathy, need for validation
• Antisocial Personality Disorder (ASPD): Disregard for norms, manipulation, limited remorse
• Histrionic Personality Disorder: Attention-seeking and heightened emotional expression

These patterns are less about formal diagnosis and more about anticipating behaviours that influence care delivery.

Attachment and the Clinical Relationship

Attachment dynamics play a central role in shaping patient behaviour. Patients may demonstrate:

• Rapid shifts between idealization and devaluation
• Boundary testing
• Sensitivity to perceived inconsistency

These behaviours reflect maladaptive coping mechanisms rather than intentional manipulation.

Key implications for primary care providers:

• Maintain consistency and predictability
• Set clear, explicit boundaries
• Recognize and manage emotional responses within the care relationship

Risk Assessment: Structured, Not Reactive

Risk assessment is essential, particularly in patients with borderline traits.

Suicide risk:
Primary care providers should distinguish between chronic baseline risk and acute escalation by assessing history, triggers, and changes from baseline.

Violence risk:
When relevant, consider impulsivity, substance use, and history of aggression.

A structured, measured approach is more effective than reactive responses.

Treatment Approach

Psychotherapy remains the primary treatment modality, with strong evidence for structured approaches such as Dialectical Behaviour Therapy (DBT).

Primary care providers play an important role in reinforcing therapeutic strategies, supporting adherence, and coordinating care. Medications are adjunctive and should be used cautiously to target specific symptoms, avoiding unnecessary polypharmacy.

Practical Strategies for Primary Care

Dr. Johnson emphasized several high-yield strategies:

• Set and maintain boundaries: Define expectations and avoid reactive changes
• Use structured communication: Stay focused and validate without reinforcing maladaptive behaviours
• Avoid crisis-driven care: Recognize recurring patterns and prioritize long-term management
• Support without overextending: Provide continuity without assuming full responsibility for complex needs

Referral Considerations

Referral to psychiatry may be appropriate in cases of diagnostic uncertainty, escalating risk, or need for specialized psychotherapy. However, given access limitations, primary care often remains the central point of continuity.

Key Takeaways

• Personality disorders are best understood as longitudinal patterns
• Cluster B traits are common and impact care delivery
• The therapeutic relationship requires structure, boundaries, and consistency
• Risk assessment should distinguish chronic risk from acute escalation
• Psychotherapy is the foundation of treatment; medications play a limited role
• Effective care relies on structured, sustainable approaches rather than reactive management

For primary care providers managing complex behavioural presentations, this framework emphasizes a critical shift: focus on patterns, maintain structure, and build stable, consistent care relationships over time.
