an elder sitter, also known as an elder companion, is someone that visits with elders in an attempt to keep them company and entertained

Elders' companion and housekeeper needed must be Filipino with outgoing personality caregiving for an elder couple in good shape

She stayed with friends or worked as a live-in child- or elder-minder while continuing high school and part-time work.

Many health aides are grouped with babysitters in U.S. labor laws, and so those who hire them are exempt from paying them any greater wages than you would a babysitter.
Despite their differences, the category these occupations share is called “companionship worker.” This category assumes that home health aides spend at least 80% of their workweek solely keeping a patient company. Consider the inaccuracy and insulting nature of the following quote: What they do is static, there’s not a lot of effort.” ...

I think in these cases you just have to give the nearest equivalent, without being too obscure and then if it is important, put a brief explanation in brackets or footnote, with a reference to a book explaining the whole thing, if available.
Mind you levels A and B really are weird, except for the babysitter for children. Level C is a personal care assistant.

That is a bit like, talk to the dear old fellow and keep him company, but if he drops his handkerchief, then whatever you do, don't pick it up. I think it is a care assistant, which doesn't do nursing (a nurse) and doesn't do shopping and housework (a home help in the UK) i.e. a "care assistant"?
This would seem to me to be a "carer" (volunteer) but the context gives "dipendente". I think much of our translation work is trying to fit Italian square pegs into English round holes.
It sounds a bit weird you saying they only provide company for the "autosufficienti". Personally as long as I can manage to wipe my own proverbial .... I'll also be quite able to make sure I get to the nearest bar and find my own company.

I found an ugly-sounding "companionship worker" (US sites) but there must be a better way of saying it
