Katz Index of Independence in Activities of Daily Living

The Katz ADL index rates six basic self-care activities as independent or dependent: bathing, dressing, toileting, transferring, continence, and feeding. The total, from 0 to 6, shows how much hands-on help an older person needs. See how to rate each activity, what each total means, and record the result with the free template.

Who holds it

Developed by Dr. Sidney Katz and colleagues, first published in JAMA in 1963. The Try This version, issue 2 of the General Assessment Series, is published by the Hartford Institute for Geriatric Nursing at NYU Rory Meyers College of Nursing, with a scoring sheet slightly adapted from Katz and colleagues’ 1970 paper in The Gerontologist.

How you may use it

The Hartford Institute lets anyone download, reproduce, and share the Try This issue whole, without asking, for not-for-profit education, as long as the Institute is credited as the source. Commercial use and republishing need permission, so this page names the activities and sends you to the official sheet instead of copying it.

  • Annual check-ups

What the score means. 0 to 6, activities done independently.

0 to 2: Severe functional impairment

Dependent in four or more basic activities. The person needs hands-on help every day: plan who gives it, what equipment helps, and where care is best given.

3 to 4: Moderate impairment

Dependent in two or three activities, most often bathing and dressing first. Arrange regular help with personal care, and look for causes that can be treated.

5: Dependent in one activity

Not full function: one activity, usually bathing, needs help. Find out why, arrange help or equipment for it, and rescore after any illness.

6: Full function

Independent in all six basic activities. Record it as the baseline, and ask about instrumental activities, where decline usually shows first.
  • Give one point for each activity the person does with no supervision, direction, or personal help, and 0 when any of these is needed. The total runs from 0, very dependent, to 6, independent.
  • The source reads the total this way: 6 is full function, 4 is moderate impairment, and 2 or less is severe functional impairment. It doesn’t name 3 or 5; this page groups 3 with moderate impairment and shows 5 as dependent in one activity, because one lost activity already means someone has to help.
  • Rate what the person actually does, not what they could do. Someone who is able but doesn’t do an activity, or refuses to, scores 0 for it.
  • The official sheet defines independence for each activity, and some definitions allow equipment or a limited amount of help. Score against those definitions, and say which sheet you used, since services have adapted the index over the years.
  • The index is most useful as a baseline taken when the person is well, compared with later scores. A fall of even one point is a real change in the help a person needs.
  • It has a ceiling: many older adults living at home score 6, so it misses early decline. Pair it with the Lawton IADL, which covers shopping, cooking, medicines, money, and similar tasks. It also moves in big steps, so it shows small gains in rehabilitation poorly.
  • Losses tend to follow an order, with bathing first and feeding last, and recovery usually runs the other way. A pattern that breaks the order, such as new incontinence with bathing intact, points to a specific cause worth looking for.
  • The 1963 original graded people with letters from A, independent in all six, to G, dependent in all six, instead of a number. Older records may use the letters.

How to give it, score it, and read it.

Rating what the person does

The Katz index rates actual performance in the six activities, not ability. Base each rating on what you see, what the person tells you, and what the people who help them every day report.

  • Watch an activity when you can: getting out of a chair, walking to the toilet, putting on a cardigan
  • Ask the person how each activity went over the past few days
  • Check with a spouse, family member, carer, or the nursing notes, especially when memory or insight is poor
  • Write down where each rating came from

Avoid: Scoring what the person says they could do. “I could shower on my own if I had to” isn’t independence if their daughter helps every time.

Scoring each activity

Each activity scores 1 when it’s done with no supervision, direction, or personal help, and 0 when any of these is needed. Add them for a total from 0 to 6.

  • Read each activity’s definition on the official sheet before you score it; some allow equipment or limited help
  • Count someone standing by for safety as supervision: 0
  • Count reminders or step-by-step prompting as direction: 0
  • Record the detail behind each 0: what help, who gives it, and how often

Avoid: Rounding up a borderline activity because the person mostly manages. If a person has to be there, the activity scores 0.

Reading the total

The source reads 6 as full function, 4 as moderate impairment, and 2 or less as severe functional impairment. Which activities were lost matters as much as the count.

  • Name the dependent activities in the result, not only the number
  • Expect bathing and dressing to go first and feeding last
  • Look harder at a pattern out of order, such as new incontinence or a feeding problem with the other activities intact
  • Read the total with cognition, mood, pain, and the home in mind

Avoid: Treating two totals of 4 as the same need. Help with bathing and dressing is a different care plan from help with transfers and continence.

Baseline and change

The index earns its place over time: a baseline when the person is well, then scores on admission, at discharge, and at home afterwards.

  • Record the usual state before an illness as well as today’s score
  • Compare with the baseline and name the activities gained or lost
  • Rescore after a hospital stay, a fall, a new diagnosis, or a change in living situation
  • Use a more detailed measure, such as the Barthel Index, to track small gains in rehabilitation

Avoid: Calling a score of 6 “no problems.” The index has a ceiling, so add instrumental activities and mobility to catch early decline.

Turning the score into care

Each dependent activity is a care need. The result should say who meets it, how often, and with what equipment.

  • Match each dependent activity to a helper and a schedule
  • Ask the carer what they can safely keep doing, and how they’re coping
  • Look for treatable causes: pain, breathlessness, delirium, low mood, medicines, and continence problems
  • Refer for home care, occupational or physical therapy, equipment, or a geriatric assessment as needed

Avoid: Recording the score and stopping there. A total without a plan for the help it shows doesn’t change anything for the person.

Katz ADL result: 3 after a heart failure admission, home care arranged

Home visit by a community nurse, 3 days after a 10-day hospital stay

Rating

Watched him rise from his armchair, walk to the bathroom with his walker, and use the toilet. Bathing, dressing, and continence from him and his wife, who gives all his care, over the 3 days since discharge.

The six activities

86-year-old man. Bathing: dependent; can’t stand long enough to shower, and his wife helps him over the tub edge and washes his legs and feet. Dressing: dependent; she puts on his compression stockings, socks, and trousers over his swollen legs. Toileting: independent with the walker. Transferring: independent from bed and armchair, pushing up on the arms. Continence: dependent; urge incontinence since his furosemide was doubled, wets his pad most mornings. Feeding: independent; his wife cooks.

Score and change

Total 3, moderate impairment. Baseline 6 before the admission in October, from his wife. Lost bathing, dressing, and continence. Likely cause: deconditioning after the admission, leg swelling, and the higher diuretic dose.

Help needed

His wife, 83, does everything now. She has spinal stenosis and says lifting his legs into the tub hurts her back. Their daughter lives 2 hours away. He nearly fell climbing out of the tub on Sunday. Equipment: walker only; no grab bars or shower seat.

Plan

Home care referral sent: a home care worker for showering and dressing 5 mornings a week, starting Thursday. Occupational therapy home visit for a tub transfer bench, grab bars, and a raised toilet seat. Home physical therapy for strength and walking. Asked his family doctor to review the diuretic timing and the new incontinence; pads supplied for now. Lawton IADL done the same visit. Carer support information given to his wife. Rescore in 4 weeks, or sooner after a fall or readmission.

Common mistakes, and how to avoid them.

Rating ability instead of performance

The index asks what the person does. If their spouse dresses them every morning, dressing is dependent, even if they say they could manage.

Scoring standby help as independent

Supervision and prompting both score 0. A person who showers only when someone waits outside the door isn’t independent in bathing.

Recording only the total

A bare “Katz 4” doesn’t say which activities need help or who gives it. List each activity, its rating, and the detail behind it.

Taking a 6 as the whole picture

Most older adults living at home score 6. Ask about shopping, cooking, medicines, and money too, and watch them walk, to catch decline early.

Calling a sick-day score the baseline

A score taken during delirium or an acute illness shows today’s needs. Record the usual state before the illness as well, and say where it came from.

Frequently asked questions.

How do you score the Katz ADL?

Rate each of the six activities as independent or dependent. An activity scores 1 when the person does it with no supervision, direction, or personal help, and 0 when any of these is needed. Add them for a total from 0 to 6, where 6 is fully independent and 0 is very dependent. Score against the definitions on the official sheet.

What does a Katz ADL score mean?

The Hartford Institute’s guide reads 6 as full function, 4 as moderate impairment, and 2 or less as severe functional impairment. It doesn’t name 3 or 5: a 5 means one activity, usually bathing, needs help, and a 3 is usually read with moderate impairment. Always say which activities were lost, since the same total can mean different care needs.

What are the six activities in the Katz index?

Bathing, dressing, toileting, transferring, continence, and feeding. They’re the basic self-care activities a person needs to live without hands-on help. The official sheet sets out what counts as independent for each one.

What is the difference between the Katz ADL and the Lawton IADL?

The Katz index covers basic self-care, the activities lost late in decline. The Lawton IADL covers instrumental activities needed to live alone: using the telephone, shopping, preparing food, housekeeping, laundry, transportation, managing medicines, and handling money. Those usually go first, so the two are often given together.

How is the Katz index different from the Barthel Index?

The Barthel Index rates 10 activities, adding grooming, walking, and stairs, and splits bowel and bladder, for a score from 0 to 100. Its finer steps show small gains better, which is why rehabilitation teams prefer it. The Katz index is quicker and gives a plain picture of how much hands-on help someone needs.

Who can give the Katz ADL?

Nurses use it most, but any clinician who knows the definitions can rate it: physicians, occupational and physical therapists, social workers, and trained care staff. It takes a few minutes when you can watch the person or ask someone who helps them every day.

What do the Katz letter grades A to G mean?

The 1963 original graded people with letters instead of a number: A for independent in all six activities, G for dependent in all six, and the letters between for losses in the usual order, starting with bathing. Most services now use the 0 to 6 total, but older records may show the letters.

Is the Katz ADL free, and where do I get it?

It’s free to download from the Hartford Institute for Geriatric Nursing as issue 2 of its Try This series, with a short guide. The Institute allows the whole issue to be reproduced and shared for not-for-profit education when it’s credited as the source; commercial use needs permission. The recording template on this page is free to copy or download.
