Are Daily Living Activities Becoming Challenging for You?

A very challenging aspect of growing old is the prospect of losing the ability to perform everyday tasks with comfort and confidence. This is particularly true for those with dementia or Alzheimer’s disease. As a result, many patients require assistance and support in order to complete their everyday tasks. There are two types of daily routines for every senior out there. These are: (i) Activities of Daily Living (ADLs) and (ii) Instrumental Activities for Daily Living (IADLs).

What’s the difference between ADLs and IADLs? Why do they matter in a patient’s care after a life-altering disease or injury? Throughout this article, we will find out the key dissimilarities between the two.

It’s important to remember that both are required for an individual to function comfortably on a daily basis. Individuals who require assistance with ADLs and IADLs can find many in-home care services that cater to their specific needs and preferences. It’s critical to grasp the differences between the two concepts if you have an aging loved one who requires care and help.

What Are ADLs?

ADLs are personal care activities that we perform every day. These include eating, bathing, dressing, toileting, and more. They are essential for maintaining a deeper level of independence. The reason is that the ability to perform ADLs indicates how much external aid a person may need.

ADLs are activities that are crucial for living in a community. For instance, actions you perform when you wake up in the morning, like freshening up and eating breakfast. These are very basic functions of life, and the inability to perform them will mean the senior will need a caregiver. A family member or a live-in caregiver will need to assist the senior with ADLs in such a case.

What Are the 7 ADLs?

The 7 basic ADLs include eating, bathing, grooming, toileting, continence, ambulating, and functional mobility.

- Eating: Feeding yourself and getting all essential nutrients and vitamins

- Bathing: The ability to use the shower and clean your body

- Dressing and grooming: The ability to dress and maintain personal hygiene

- Toileting: Recognizing the need to use and ability to use the toilet

- Continence: Control of bowel and bladder, and related actions

- Walking (or otherwise known as ambulating): Moving around with ease

- Functional mobility: Changing body position

Another example of ADL is the use of personal care devices. These are items like hearing aids, glasses, prosthetics, and such. Even if you aren’t able to carry out some of these activities, you don’t necessarily have an ADL disability.

Certain activities do serve as strong indicators. For example, losing the ability to eat can be a sign of extreme functional disability.

What Are the IADLs?

Instrumental Activities of Daily Living (IADLs) are more complex than ADLs. Examples include shopping, managing finances, housekeeping, and others. The ability to perform IADLs is a stronger sign of independence. Even so, seniors who cannot perform certain IADLs may still be considered independent.

- Shopping: Taking care of all your shopping needs, like grocerie

- Managing finances: Managing financial matters, like budgeting and bills

- Managing transportation: Traveling on public transport or driving your car

- Meal preparation: The ability to plan, prepare, and serve adequate meals

- Home maintenance: Tidying up after yourself (dishwashing, bed-making, etc.

- Managing communication: Operating the telephone

- Responsibility for own Medications: Intake in proper dosages at the right time

- Religious and spiritual activities: Carrying out religious practices and rituals

Other examples of IADLs include taking care of pets and abiding by safety procedures.

IADLs vs ADLs: The Key Differences

ADLs are everyday necessities related to personal care. IADLs may not be required daily. IADLs add value to your daily life and supplement ADLs. However, they may not directly affect your everyday routine. ADLs include eating, bathing, grooming, and toileting. IADLS includes shopping, cooking, laundry, and housework.

Brushing your teeth and eating breakfast- examples of ADLs that we need to perform every day. They aid in ensuring we are healthy and fit. However, we don’t need to do IADLs like grocery shopping or calculating bills every day. To an extent, you may not even need to take medication daily.

ADLs	IADLs
Basic everyday tasks	Supplemental tasks to live independently
Simple tasks	More complex tasks
Does not require much planning and time	May require some planning and time
Examples: Eating, bathing, walking, grooming, etc.	Examples: Money management, grocery shopping, transportation, cooking, etc.

ADL and IADL Assessment Tools: How to Measure the Loss of ADLs and IADLs?

Determining the extent of loss of an ADL or IADL is important to help ensure appropriate care and support. For this, various entities have developed several checklists. The questions in these checklists are similar, but how they’re asked makes a big difference.

ADL (Activities of Daily Living) and IADL (Instrumental Activities of Daily Living) assessment tools are widely used in healthcare and social services to evaluate an individual’s functional independence and ability to perform various daily tasks.

These assessments help determine an individual’s level of independence in these fundamental daily tasks. Common ADL assessment tools include the Katz Index of Independence in Activities of Daily Living and the Barthel Index.

IADL assessment tools, on the other hand, evaluate an individual’s ability to perform more complex, community-based activities, such as:

IADL assessments provide insights into an individual’s cognitive and functional capacity to live independently in the community. Some widely used IADL assessment tools are the Lawton Instrumental Activities of Daily Living Scale and the Functional Independence Measure (FIM).

The three common ADL and IADL assessment tools are explained below:

1. Katz Index

The Katz Index of Independence in Activities of Daily Living, or Katz ADL, is the most ideal method for assessing functional status of a senior’s capacity to do activities of daily living independently.
Doctors often use the instrument to discover issues with daily living tasks and to schedule their care plans. There are 6 functional indexes to measure the ability of seniors to perform daily activities. They are:

Bathing
Dressing
Toileting
Feeding
Continence
Transferring

Full function is indicated by a score of 6, moderate impairment by a score of 4, and severe impairment by a score of 2 or less

2. Functional Independence Measure (FIM)

The Functional Independence Measure (FIM) is a comprehensive assessment tool used to evaluate an individual’s level of disability and functional status. It includes 18 items across domains such as self-care, sphincter control, transfers, locomotion, communication, and social cognition.

The FIM uses a 7-level ordinal scale to determine the level of assistance required, ranging from total independence to total assistance. This tool is widely used to assess changes in a patient’s functional status during rehabilitation or medical interventions.

3. Lawton’s Instrumental Activities of Daily Living Scale

Lawton’s Instrumental Activities of Daily Living (Lawton IADL) is a widely used assessment tool that evaluates an individual’s ability to perform more complex, community-based activities necessary for independent living.

The Lawton IADL scale assesses the following 8 domains:

Ability to use the telephone
Shopping
Food preparation
Housekeeping
Laundry
Mode of transportation
Responsibility for own medications
Ability to handle finances

Each domain is scored on a scale of 0 to 1 or 0 to 3, depending on the specific item, with higher scores indicating greater independence. The total score ranges from 0 (low function, dependent) to 8 (high function, independent) for women, and 0 to 5 for men, as some items are considered gender-specific.

The Lawton IADL assessment is particularly useful for evaluating an individual’s ability to live independently in the community. It provides valuable information about an individual’s cognitive and functional skills, which are crucial for tasks such as managing finances, using transportation, and maintaining a household.

These assessment tools are commonly used in various settings, such as hospitals, rehabilitation centers, long-term care facilities, and community-based programs. They help healthcare professionals and social workers develop personalized care plans, monitor changes in functional status over time, and determine the appropriate level of support or intervention required for an individual.

How Significant Are These IADL and ADL?

Understanding IADL vs. ADL will help older adults to determine their physical and mental health. You may consider it a simple task of ticking through a checklist of activities. However, that isn’t the case. You should always consult with a doctor. A doctor will provide the proper diagnosis and identify factors that you might miss out. Even if you use the checklists mentioned above for a self-diagnosis, please show them to a doctor.

A doctor can also determine whether patients will need further rehabilitation or support.
It’s also crucial to recognize the impact of a loss of ADL on the patient. It will affect the cost of arranging Senior Living options such as assisted living or home care services and insurance policies for disabilities and long-term care.

Conclusion

IADL vs ADL – it’s an important topic of discussion among many doctors. Proper diagnosis of these activities aids in providing better treatment.

IADL and ADLs are quite distinct from each other and have separate checklists. However, studies have been conducted to see whether they can be combined into a single scale to measure functional disability. Here is one such study on combining ADLs and IADLs. Here is a study on disability trends in older adults.

As we’ve learned, ADL and IADL consist of several basic and complex activities. They are essential for maintaining an independent lifestyle. They work as useful indicators to determine the early stages of certain diseases. It’s because they act as a measure of one’s ability to care for oneself.

FAQs

How do ADLs differ from IADLs?

There are key differences between IADLs and ADLs. IADLs are more complex and involve more coordination than ADLs. Also, IADLs are often associated with higher levels of independence than ADLs.

How does cognitive ability relate to ADL and IADL?

Cognitive ability is related to ADL and IADL in that those with more cognitive ability are better able to perform activities of daily living and instrumental activities of daily living. This is likely due to the fact that those with more cognitive ability are better able to problem solve, remember instructions, and make decisions.
