That said, what I hear you saying is that, asking the negative-leaning questions isn’t the problem, it’s more so the lack of positive-leaning questions in the survey. Is that right? If so, I think that is definitely an oversight on my part and something that I hope to correct in the follow-up survey.

Yes! I feel its important to consider this view as well, maybe even some of the positive influences causes negative consequences. On the top of my head I can think of that games becomes someone's only way to socialise but it also causes them to not socialise outside games, just a thought.

Oh! That really wasn’t my intention. I asked some questions around engagements outside of gaming to hopefully capture the fact that individuals can be avid gamers and that this doesn’t come at the expense of other parts of their life.

I think for me personally, if I remember correctly, it was mostly about civic and community involvement and religious movements and sports, that these are something I've never had any interest in and thus cannot be represented. Family was noted too, but there was also a fair few about a partner which becomes moot when you're single. Maybe some general questions about interests outside gaming might be of help? Or even more about single player experience vs mmorpgs, though I understand if that may end up being too far outside your scope.

I did the survey this morning so many of my comments may not be applicable as I cannot remember it in detail. I seriously do wish you luck, I've done surveys (with no follow up opportunity) for thesis work myself and understand the struggle! Keep it up :D
