Treating a single difficult or unusual trait as a personality disorder
-
1. The tempting shortcut
"This person's way of relating to others is unusual and causes friction, so this must be a personality disorder."

2. Stop and think
Before you read on: what is wrong with this reasoning? Try to answer in your own words, then reveal the explanation below.

3. Reveal — why it fails
F60 requires a pervasive, inflexible pattern affecting several areas of personal functioning (cognition, affectivity, impulse control, interpersonal relating), present since childhood, adolescence, or early adulthood, and associated with considerable personal or social disruption — not a single trait, however striking, in an otherwise well-functioning person. Most people have some traits that could be described as difficult or unusual without meeting this threshold.

4. Reveal — the better reasoning rule
- Does the pattern affect several areas of personality (cognition, affect, impulse control, interpersonal functioning), or is it limited to one specific trait or situation?
- Has the pattern been present, essentially unchanged, since adolescence or early adulthood, or could this instead be a later, definite change from a previously different baseline (which would point to F62 instead)?
- Is there evidence of considerable personal or social disruption directly attributable to the pattern, rather than simply a trait others find unusual or that causes occasional friction?
Corrective example: In the F60 anchor category, a lifelong, pervasive pattern of disregard for social obligations and others' rights across work, relationships, and the law, present since adolescence, supports a dissocial personality disorder classification — a single unusual preference or occasional friction with a colleague does not.
