How Are Cluster C Personality Disorders Diagnosed?

There isn’t necessarily a specific cluster C personality disorders test that can be used to make a diagnosis. Personality disorders can also be more difficult to diagnose than other mental health disorders like depression because everyone’s personality is unique.

While there isn’t a standardized cluster C personality disorders test, questions a doctor may ask relate to the following:

  • How do you perceive yourself, other people and situations and events?
  • How do you respond emotionally to certain situations, and are your responses appropriate to the situation at hand?
  • How do you manage relationships and deal with others?
  • What is your impulse control like?

Some health care providers may ask you questions verbally, or they may have a written questionnaire where you add your responses.

In some cases, a doctor or mental healthcare provider might ask to speak with people you’re close to or who know you well, such as a family member.

When testing for cluster C personality disorders, sometimes speaking to the people who know you best is the most effective way to make a diagnosis since someone with a personality disorder may be unaware of the effects it has on others and even themselves.
