Understanding Society User Support

Hi. I am researching the mental health of self employed people and I note that in wave 12 of the survey there is a very interesting self completed section on sex and gender . However, there does not appear to be a follow up (or proceeding) equivalent set of questions.

I am just checking that this is the case and that aside from wave 12 there is no way of determining of the individual assigns themselves as a different gender to that they were born with?

Thank you,

Damien.
