As an aside I'd be concerned with the number of open ends contained in your survey. Might be an idea to change some to locked in with an option for comment after.
Especially when you consider that most questions are either yes/no, or have a short list of options contained in the question. The questions are "closed" but the answers are "open".
It would be a nightmare to post-process.
Also the question:
Do you think homophobic behavior affects one's mental health?
Could concern the victim or the perpetrator. Obviously he means the victim, but the wording is far from clear.
And final question: "Do you have any further comments or comments?". Anyone sees a problem with it?
For a final year thesis, you may want to spend a bit more time polishing your questionnaire. (Brutal honest feedback...)
