Part of the requirements for diagnosing personality traits as a disorder are that it must be pervasive and chronic in the person's life...affecting more than one area of life, i.e. work, relationships, self-concept, self-care etc. There is usually evidence that these traits were present from at teenage years. The patterns of behavior related to the personality traits must cause distress or dysfunction.

So there is a broad range from someone possessing certain traits and having a clinically defined personality disorder.
