Okay... Now I'm fairly sure:

1) Residual Type is when someone presents with both positive symptoms (delusions, hallucinations, formal thought disorder etc) and negative symptoms (withdrawal, a-volition etc) AND the positive symptoms have been successfully treated and the continued presence of negative symptoms is classified 'Residual Type'.

2) In Remission is then the symptoms of the previous disorder haven't been observed for the last... 2 years, I'm thinking. I'm fairly sure about that, though it might be less than 2 years if medication kicked in...

So: In order to meet criteria for that one you would need to firstly, have a diagnosis of schizophrenia, secondly have a diagnosis of residual type, and then you could get that diagnosis.

You have never been diagnosed with schizophrenia (much less residual type) and hence there is no way you could meet criteria for residual type in remission.

It has to be a mistake.
