You will want to use the likert scale as much as possible. Repeat key questions phrased differently. There is a whole.. well maybe science is too strong a word but their is good practice for making a good survey, lots of info available on it.
I would ask questions something like the following but psychology is not my area and these are just a small set of the top of my head and don’t cover all the aspects you are trying to record. :)
E.g Strongly Disagree to Strongly Agree for all:
Most games I play portray extensive physical violence:
I would like a more active non game related social life.
I find the level of violence portrayed in mature content repugnant.
Were I not playing games I would have much greater time for a non game related social life.
I prefer to play alone.
Time spent playing games is not a major influence on the time I could devote to my social life.
I have formed casual relationships through games.
I would choose to play cooperatively over adversarialy.
I cannot connect emotionally with characters in games.
My personality becomes more aggressive while playing a game.
I have formed lasting personal relationships through games.
Violence portrayed in games does not affect me.
I am an empathic person.
Online relationships are as valid as in person relationships
I am a competitive person
Violence scenes on the news can disturb me
I am particularly competitive while playing games
I am less open in conversion to players than people in general life.
I feel my circle of friends is smaller than most.
I get depressed when not achieving as I would wish in a game
I would like to spend less time playing games.
I prioritise playing or finishing a game over most other activities
