Activities of Daily Living (ADL) Score Calculator

The Katz Index of Independence in Activities of Daily Living (ADL) assesses functional status by measuring a patient's ability to perform six basic activities independently. It is widely used to identify functional decline in older adults and to plan care needs.

Bathing

Independent – Bathes self completely or needs help only for one body part Dependent – Needs help with more than one body part or cannot bathe self

Dressing

Independent – Gets clothes, dresses/undresses without help (except tying shoes) Dependent – Needs help dressing or is completely unable to dress self

Toileting

Independent – Goes to toilet, cleans self, arranges clothes without help Dependent – Needs help transferring to toilet or with cleaning/arranging clothes

Transferring

Independent – Moves in/out of bed or chair without help (may use assistive device) Dependent – Needs help moving from bed to chair or is completely immobile

Continence

Independent – Exercises complete self-control over urination and defecation Dependent – Is partially or totally incontinent of bowel or bladder

Feeding

Independent – Gets food from plate into mouth without help (cutting/preparing food excluded) Dependent – Needs partial or total help with feeding, or requires parenteral feeding

Calculate ADL Score

function actCalc() { var errorEl = document.getElementById('act-error'); var resultEl = document.getElementById('act-result'); errorEl.style.display = 'none'; resultEl.style.display = 'none';

var fields = ['act-bathing','act-dressing','act-toileting','act-transferring','act-continence','act-feeding']; var labels = ['Bathing','Dressing','Toileting','Transferring','Continence','Feeding']; var scores = [];

for (var i = 0; i = 4) { interpretation = 'Score ' + total + ' – Moderate Independence: Patient is independent in most ADL functions but requires some assistance. Mild functional impairment; consider monitoring and preventive support.'; interpretClass = 'calc-result-warning'; } else if (total >= 2) { interpretation = 'Score ' + total + ' – Moderate Dependence: Patient requires significant assistance with multiple ADL functions. Moderate functional impairment; formal care planning and support services are recommended.'; interpretClass = 'calc-result-warning'; } else { interpretation = 'Score ' + total + ' – Severe Dependence: Patient is dependent in most or all ADL functions. Severe functional impairment; comprehensive care support or placement evaluation is strongly recommended.'; interpretClass = 'calc-result-abnormal'; }

// Build individual item summary var itemSummary = ''; itemSummary += 'ActivityScoreStatus'; for (var k = 0; k Independent' : 'Dependent'; var bg = k % 2 === 0 ? '#fff' : '#f9f9f9'; itemSummary += '' + labels[k] + '' + s + '' + status + ''; } itemSummary += 'Total ADL Score' + total + ' / 6'; itemSummary += '';

var scoreDisplay = document.getElementById('act-score-display'); var interpDisplay = document.getElementById('act-interpretation');

scoreDisplay.innerHTML = '### Katz ADL Score: ' + total + ' / 6 ' + itemSummary; interpDisplay.innerHTML = '' + interpretation + '';

resultEl.style.display = 'block'; }

#### Formula

Katz ADL Score = Bathing + Dressing + Toileting + Transferring + Continence + Feeding

Each of the six activities is scored as:

Total score range: 0–6

ScoreInterpretation 6Full independence in all ADLs 4–5Moderate independence; mild functional impairment 2–3Moderate dependence; significant functional impairment 0–1Severe dependence; comprehensive care required
