Hey, I am studying psychology. The data is not to be used in I am trying to create a questionnaire looking at online gambling behaviours amongst the adult population to test the validity of this questionnaire against other questionnaires and whether it is a good method to use.
I am also looking at the gaming population aswel considering these issues.The left handed and right handed is just to see if this effects results in any way and to make sure that we know alot about our sample and it is representative of the general population.
Also my lecturer actually works with online gambling websites and gambling companies, bookies etc to find ways to help prevent problem gambling, I'm not sure if they conducted their research through questionnaires but have gathered information on through case studies and interviews.
But obviously you don't have to fill out the questionnaire at all if you dont like any aspect of it.
