Given the volume of work which now exists on this, it is striking how extroversion/introversion plays no real part in either ICD–10 or DSM–IV. These are well-used and well-understood terms which are easily measured using the Myers–Briggs Type Indicator. With the development of ICD–11 and DSM–V, is it now time for this to be reviewed and perhaps included in a more substantial way?
There is also a wider issue here apart from diagnosis. Should introverts have different treatment approaches from extroverts? Are different types of drugs likely to be more successful? How does being an introvert compared with an extrovert change the way an individual perceives and deals with mental illness?
