Imagine visiting your older people grandmother. She can brush her teeth, dress herself, and eat without help, but she struggles to pay bills, cook meals, or manage her medications. In healthcare and social work, these abilities are categorized as ADL (Activities of Daily Living) and IADL (Instrumental Activities of Daily Living).
Understanding the difference between ADL and IADL is crucial for caregivers, medical professionals, and family members.
While ADLs focus on basic self-care tasks, IADLs involve more complex activities that allow an individual to live independently in a community.
Many learners and experts often confuse these two terms, but knowing their distinction can significantly improve care planning and quality of life assessments.
Pronunciation:
