F61 — Mixed and other personality disorders: facilitator sheet

Teaching objective

F61 exists to prevent a learner from forcing a genuinely mixed or atypical personality disturbance into whichever single F60 type it most resembles. The test is the same general personality-disorder threshold as F60; what differs is that no single named pattern dominates clearly enough to justify a specific F60 code.

Worked example

Show scenario

A 40-year-old has, since adolescence, shown a pervasive pattern combining marked suspiciousness of others' motives, a strong need for orderliness and control, and periodic emotional instability in close relationships, causing significant difficulty at work and at home. No single one of these three patterns clearly predominates over the others; each is present to a similar, clinically significant degree.

(or reveal one step at a time below)
  1. Reveal step 1

    Step 1 — Confirm the general threshold: pervasive since adolescence, causing real difficulty across contexts.

  2. Reveal step 2

    Step 2 — Check whether one F60 type's pattern predominates: paranoid, anankastic, and emotionally unstable features are all present to a similar degree, with none clearly dominant.

  3. Reveal step 3

    Conclusion — F61.0, Mixed personality disorders — the general threshold is met, but no single named type is the clearly better fit.

Comparison points

F61 requires the same general personality-disorder threshold as F60, applied when no single named type's pattern clearly predominates — it is a different fit, not a lower bar.

Discussion prompts

(or reveal one at a time below)
  1. Prompt 1

    Explain what distinguishes F61 from any specific F60 type.

  2. Prompt 2

    State why F61 is not a lower diagnostic threshold than F60.

  3. Prompt 3

    Explain the check that should be made before applying F61 rather than a specific F60 code.

Summary

F61 applies the same personality-disorder threshold as F60, used when no single named type's pattern clearly predominates.
