^(a)An item was said to be endorsed if it was answered at the level of Often or Very Often.

^(b)Due to the binary wording of this question (“have you ever tried to limit”), this scale question was converted into the response types listed to appropriately capture the conditional nature of the question; the resulting three categories (could limit, can’t limit, never limit) were used in analysis. Of the original first part of that question, 4,054 participants (52.3%) answered that they had tried to limit gaming, and 798 participants (10.3%) answered at Often or Very Often.
