Project Details


The proposed research seeks to apply human factors research techniques from
a successful pilot project to accomplish a person capability - environment
demand analysis of older adult functioning for a select set of activities
of daily living (ADLs) involving instrumental behavior. The overall
objectives of the proposed research aim at: (1) empirically specifying
parameters for environment designs and technologies for daily living which
reduce demands for specific instrumental capabilities; and (2) estimating
their potential for extending functional abilities of older adults via
development and test of a task-based protocol for assessment of
instrumental capabilities having demonstrated relevance to ADL task demands
with samples of older adults reflecting a range of ADL performance
capabilities. The long term goal of this research is to demonstrate the
power of human factors research techniques in the study of functional
abilities in advancing age and design of competency enhancing environments
for older persons. Three major phases of activity over a three-year
project period. An activity survey of 250 adults over age 60 years serves
as a basis for selecting a subsample (90 cases) for videotape recording of
actual or simulated activity performance in each of eight activity areas
involving instrumental behaviors (e.g., shopping, cooking, getting in/out
of a bathtub). Videotape records form the basis for task analysis of
activities using a developed methodology which (a) specifies transactions
between the older adult and the environment involved in each of the eight
activity clusters; and (b) resolves transactions in terms of comparable
person and environment components and specific characteristics of both
which are relevant to task performance (e.g., pedestrian mobility and
postural change under conditions of transport load and barrier negotiation,
and manual dexterity and force application as a function of specific task
and objects, tools, or devices in the environment. Age comparable samples
are drawn from various levels of community care and ambulatory
institutional care to compare sample capabilities with levels of
environment demand associated with task areas in which they experience
problems and/or receive support.
