Can I say, with very good intentions, that you are not focussing at all?

You have an interesting population, but you will need a control group. When you evaluate them, you will have to compare them with the expected performance of children from a similar setting whose parent(s) are not prisoners.

Second, you need a particular question, not a basketful of measures. What is know on this topic already? Which measures would point the way to specific intervention programmes, and which would be useful to programmes that are already in place?

Choose a particular outcome, be it behavioural, developmental, academic, social etc. Get up to speed in the literature on that area. Evaluate the usefulness of the currently-used measures (given that you will probably have to translate and field-test the measure you use).

Then start designing your study.

If I can add something- now we have a lot of  methods to measure many of your variables.  But which will be siuted to your research is depend on idea of research (perspective, theory, plan). 

If have contact to the same group - the society to help children from prosoners family - check The open Journal of  Criminology Napadło
