Family caregivers

"Caregivers"[Mesh] OR caregiver*[tiab] OR carer[tiab] OR carers[tiab]
AND
"Family"[Mesh] OR family[tiab] OR familial[tiab] OR informal[tiab] OR unpaid[tiab]

Of course, it works better with adjacency:

exp Caregivers/ and (exp Family/ or (family or familial or informal or unpaid).ti,ab.)
or
((family or familial or informal or unpaid) adj3 (caregiver* or carer*)).ti,ab.


EMBASE:
exp caregiver/ and (exp family/ or (family or familial or informal or unpaid).ti,ab.)
or
((family or familial or informal or unpaid) adj3 (caregiver* or carer*)).ti,ab.

But in PsycInfo, it gets a little crazy:
