The Care Dependency Scale consists of 15 items (e.g., food and drink, continence, mobility). The sum score ranges from 15 to 75 points [34, 35] and can be categorized into five categories: Completely dependent on care from others, to a great extent dependent, partially dependent, to a great extent independent and care independent [36, 37]
