Lawton Instrumental Activities Form PDF Details

In an era where the aging population is rapidly increasing, the necessity of assessing the functional status of older adults cannot be overstated. Changes associated with aging, acute or worsening chronic illnesses, and the impacts of hospitalization significantly contribute to declines in the ability to independently perform daily tasks, making assessments like the Lawton Instrumental Activities of Daily Living (IADL) Scale critical. Developed as a tool to evaluate more complex life skills beyond basic self-care, the Lawton IADL Scale delves into eight domains of function, offering insights into an individual's capacity for independent living within the community. This instrument originally differentiated between gender in scoring, but has evolved to equally assess all domains regardless of gender, ensuring a more inclusive approach. Validity and reliability assessments have underscored its usefulness in both research and clinical settings, though it's best suited for community-dwelling adults rather than those in institutional settings. Administered through self or surrogate reports, the Lawton IADL Scale identifies specific deficits, guides rehabilitation or in-home service planning, and supports safe discharge planning from hospitals. Despite its limitations, including potential biases in self-reporting and sensitivity to minor functional changes, this tool remains instrumental in evolving the care provided to older adults, highlighting the urgent need for tailored interventions and resources to maintain and enhance their quality of life.

The Lawton Instrumental Activities of Daily Living (IADL) Scale

By: Carla Graf, PhD(c), MS, RN, GCNS-BC, University of California, San Francisco

WHY: The assessment of functional status is critical when caring for older adults. Normal aging changes, acute illness, worsening chronic illness, and hospitalization can contribute to a decline in the ability to perform tasks necessary to live independently in the community. The information from a functional assessment can provide objective data to assist with targeting individualized rehabilitation needs or to plan for specific in home services such as meal preparation, nursing and personal care, home-maker services, financial and medication management, and/or continuous supervision. A functional assessment can also guide the clinician to focus on the person’s baseline capabilities, facilitating early recognition of changes that may signify a need either for additional resources or for a medical work-up (Gallo & Paveza, 2006).

BEST TOOL: The Lawton Instrumental Activities of Daily Living Scale (IADL) is an appropriate instrument to assess independent living skills (Lawton &

Brody, 1969). These skills are considered more complex than the basic activities of daily living as measured by the Katz Index of ADLs (See Try this: Katz Index of ADLs). The instrument is most useful for identifying how a person is functioning at the present time and for identifying improvement or deterioration over time. There are 8 domains of function measured with the Lawton IADL scale. Historically, women were scored on all 8 areas of function; men were not scored in the domains of food preparation, housekeeping, laundering. However, current recommendations are to assess all domains for both genders (Lawton, Moss, Fulcomer, & Kleban, 2003). Persons are scored according to their highest level of functioning in that category. A summary score ranges from 0 (low function, dependent) to 8 (high function, independent).

TARGET POPULATION: This instrument is intended to be used among older adults, and may be used in community, clinic, or hospital settings. The instrument is not useful for institutionalized older adults. It may be used as a baseline assessment tool and to compare baseline function to periodic assessments.

VALIDITY AND RELIABILITY: Few studies have been performed to test the Lawton IADL scale psychometric properties. The Lawton IADL Scale was originally tested concurrently with the Physical Self-Maintenance Scale (PSMS). Reliability was established with twelve subjects interviewed by one interviewer with the second rater present but not participating in the interview process. Inter-rater reliability was established at 0.85. The validity of the Lawton IADL was tested by determining the correlation of the Lawton IADL with four scales that measured domains of functional status, the Physical Classification (6-point rating of physical health), Mental Status Questionnaire (10-point test of orientation and memory), Behavior and Adjustment rating scales (4-6-point measure of intellectual, person, behavioral and social adjustment), and the PSMS (6-item ADLs). A total of 180 research subjects participated in the study, however, few received all five evaluations. All correlations were significant at the 0.01 or 0.05 level. To avoid potential gender bias at the time the instrument was developed, specific items were omitted for men. This assessment instrument is widely used both in research and clinical practice.

STRENGTHS AND LIMITATIONS: The Lawton IADL is an easy to administer assessment instrument that provides self-reported information about functional skills necessary to live in the community. Administration time is 10-15 minutes. Specific deficits identified can assist nurses and other disciplines in planning for safe hospital discharge.

A limitation of the instrument includes the self-report or surrogate report method of administration rather than a demonstration of the functional task. This may lead either to over-estimation or under-estimation of ability. In addition, the instrument may not be sensitive to small, incremental changes in function.

FOLLOW-UP: The identification of new disabilities in these functional domains warrants intervention and further assessment to prevent ongoing decline and to promote safe living conditions for older adults. If using the Lawton IADL tool with an acute hospitalization, nurses should communicate any deficits to the physicians and social workers/case managers for appropriate discharge planning.
