Case Formulation: Creating Problem Lists and Using Diagnosis Summary & Study Notes

🧭 Purpose of a Problem List

Creating a problem list gives therapy focus and direction. Shared agreement about which problems to address strengthens the therapeutic alliance and predicts better outcomes. A problem list also helps prioritize which issues to treat directly and which to address indirectly (for example, resolving financial stress can reduce anxiety and improve functioning).

🔍 What Counts as a Problem?

A problem can be defined as a discrepancy between a perceived state and a desired state. Problems appear in several forms: symptoms (subjective experiences like hearing voices or panic sensations), signs (observable reactions such as blushing, stiffening, or behavioral leakage), and broader problems in living (social isolation, poor self-care, inability to keep employment).

🧩 Core Domains for Organizing Problems

A comprehensive problem list should cover multiple domains so nothing important is missed. The framework presented is hierarchical, cross-theoretical, and parsimonious. Key domains include:

• Red flags: immediate/high-risk issues such as suicidality, homicidality, severe substance dependence, domestic violence, and neglect. These should be prioritized even if the client minimizes them.

• Self-functioning: subdivided into behavior, cognition, affect/mood, biological, and existential.

  • Behavior: excesses (addiction, impulsivity, avoidance) or deficits (poor assertiveness, withdrawal).
  • Cognition: absences of awareness, distortions (e.g., jumping to conclusions, all-or-nothing thinking), identity confusion.
  • Affect/mood: excessive fear, chronic shame, blunted affect, or instability and lability.
  • Biological: medical or physiological contributors (e.g., hypothyroidism, diabetes) that may cause or worsen psychiatric symptoms.
  • Existential: concerns about meaning, responsibility, mortality, or fundamental loneliness.

• Social/interpersonal functioning: relationship instability, deficits in interpersonal skills, isolation, problematic family or provider relationships, and socioethnic/cultural stressors (e.g., acculturative stress, language barriers).

• Societal functioning: structural problems such as poverty, inadequate housing, transportation barriers, noisy or unsafe environments, limited educational or employment opportunities, and food insecurity.

✅ Why Cast a Wide Net?

Problems often overlap categories and may be distal or proximal. Reviewing past problems clarifies current presentations. Some issues (medical, housing) may not be directly treatable in psychotherapy but strongly influence outcome and must be considered in the plan.

🧠 From Problem List to Diagnosis

Diagnosis has practical roles: it provides a shared vocabulary, helps retrieve relevant knowledge, suggests treatment options, and may determine access to services. However, diagnosis is not an explanation; it is a label that groups experiences.

Key cautions:

• Diagnostic reliability in practice is limited; research shows variable inter-rater agreement for many DSM categories.
• Diagnostic categories are constructs—not discrete biological entities—and were developed partly by expert consensus.
• Diagnosis can relieve some clients but can also stigmatize others.

⚖️ What Is a Mental Disorder?

The DSM defines a mental disorder as a disturbance in psychological, biological, or developmental processes associated with distress or impairment. The definition excludes expectable cultural responses (e.g., normal grief) but can be broad and sometimes blurs boundary conditions. Clinicians should consider whether problems arise primarily from individual dysfunction or from transactional/contextual factors (e.g., family roles producing a depressive presentation).

✍️ Practical Suggestions for Problem Formulation

• Explicitly identify and prioritize problems with the client. Agreement on targets and goals improves collaboration.
• Be theoretical but descriptive: describe problems in neutral, observable terms ("inability to form intimate relationships") rather than theory-laden labels ("unresolved Oedipal conflict").
• Stay curious and avoid unwarranted assumptions. Use a “beginner’s mind” to probe beneath surface presentations.
• Be alert for avoidance-driven talk where a seemingly central problem masks a more painful, avoidant core issue.
• Reassess diagnosis if treatment does not proceed as expected; the problem list can guide which domains to re-evaluate.

🧾 Diagnostic Considerations in Case Formulation

• Use multiple information sources (interview, collateral reports, records, brief measures) and cast the diagnostic net broadly to capture problems clients may not volunteer.
• Apply diagnostic criteria carefully to improve reliability, but remember criteria are guides, not full explanations.
• Consider medical contributors to psychiatric symptoms (e.g., diabetes, hypothyroidism) and address them when relevant.

🧩 Example Applications (Brief)

• A client reporting panic symptoms may actually have primary financial stress and internalized family messages; diagnosing panic without exploring context risks missing the real problems.
• Addressing a client’s unaddressed debt and building savings reduced existential helplessness and catastrophizing, which in turn reduced panic and facilitated a job search.
• In a complex case ("Rochelle"), multiple diagnoses (MDD, GAD) capture symptom clusters but may miss relational dynamics, medical contributors (uncontrolled diabetes), or strengths and functioning variability.

🔚 Conclusion

A comprehensive, systematically developed problem list is the foundation of case formulation. Use broad domains to ensure coverage, prioritize red flags, consider medical and contextual contributors, and pair a careful diagnostic process with ongoing collaboration and reassessment. This approach yields clearer explanations, more targeted interventions, and better alignment between therapist and client.
