This is a table of the different risk factors mentioned in the 'Complete Companion' textbook. Basically put into note form, highlighted and with relevant AO1 and AO2 detail. In my actual exam there was a question about risk factors and so I would have talked about some of these. I think these were stress, social learning theory and social identity theory.
It's important that you can identify the risk factors in a scenario, talk about them and then evaluate them with AO2 points, as the questions in the exam are often structured this way.
