Hello Sia

I thought that this would be studied, but could not find very much. These do not really answer your question but might be of interest. I have not accessed the full text of the first:

Lautenschlager, N. T., Kurz, A. F., Loi, S., & Cramer, B. (2013). Personality of mental health caregivers. Current opinion in psychiatry, 26(1), 97-101.

This is the full text and following, is the RG link:

https://www.researchgate.net/publication/308377110_Correlation_between_anxiety_and_personality_in_caregivers_for_patients_with_schizophrenia

Although these may touch on the subject, I have not found anything very relevant to your question. Perhaps the authors of papers on RG may be able to help you.

Very best wishes,
