FWIW, in the DSM-5, that was changed to age 12.
- dragonwriter 8y agoThis study straddles the time when the DSM-5 was published and came into general use, and in any case it didn't follow kids past age 6-8 depending on birth year, so that part of the change in criteria probably isn't relevant to the results.
