Distortion according to interpretation (10)

I believe the answer is:

perversion

'distortion' is the definition.
(thesaurus)

'according to interpretation' is the wordplay.
'according to' becomes 'per' (I've seen this before).
'interpretation' becomes 'version' (synonyms).
'per'+'version'='PERVERSION'

I've seen this clue in The Telegraph.
