EPQ-to what extent does a persons epigenetics contribute to their addiction disorder?

I was wondering if this would be a good enough biology (BTW i take bio for a level so does anyone know if this topic would cross over with the course because otherwise i don't think i could do it) /psychology EPQ question because i find it really interesting but i'm not sure if i would find epigenetics too confusing to write about. Obviously I would be writing about the psychology side too.

Any suggestions on how to structure this argument?

Also any tips for doing the literature review because i'm quite confused, our school hasn't helped us at all really.

First of all really good question. I did a science based EPQ and a good questions is often half the story. Be willing to change it to something completely if too complicated. My advice with is is write your EPQ around factors. Please note I havnt read much on epigentics (only 2 books) and havnt studies psycology so dont really know a lot a lot about it. Off the top of my head 1 factor (possibly mini title in your discussion) could be "Epigentics as a cause of addiction" and then another factor "Socio-economic background as a cause" (this is me thinking with a geography brain sorry if it isnt relevant)

Another suggestion is possibly narrow your question down to a type of addiction. E.g alcahol.

My experience of the literature review is it is the key pieces of research you used. You need to talk about the content of the source, limitations, Is the source reliable (credentials of author, is it from a academic journal etc )and usefulness to EPQ.

What year are you in? What board are you doing? When do you need to complete your EPQ by?

I know very little about epigenetics, but I junk that as long as you have a clear structure that you stick to, it should be fine. I did mine on literary and translation theory and had 3 sections each with 2-3 paragraphs which I titled prior to writing. For me, that worked well as I knew what I still had to write. I did change format and titles a little between drafts, but generally the structure was comprehensive for me from the start.

In terms of reviewing sources, you need the title, publication date, edition, author's name and publishers. Just it it all into a table (numbered) and then evaluate whether the source is reliable or not, based in teh known biases of the researcher, publisher, etc, how recent it was, history, change, etc.

thank you so much! can i ask, if yours was on a theory - did you do like an argument sort of thing...? also for your paragraphs were your titles kept for the final draft and were they more like subheadings or questions? sorry if these sound like really dumb questions we literally had 3 sessions at school in which they didn't answer any questions which is great.
