Informal caregivers are the family members and friends who provide help and support daily to individuals who are temporarily or permanently unable to function independently. They have to engage in a range of activities. They have a long term commitment to the persons they are helping and are usually not paid for their efforts. In certain Asian cultures, there is a peculiar concept that seems to be playing a great role in aiding people to adhere to their responsibility and derive satisfaction from their role of caregiving. This is known as filial piety.
