The Role Checklist: Development and Empirical Assessment of Reliability:

This article describes the development and reliability testing of the Role Checklist, a two-part written inventory designed to identify past, present, and future roles and the degree to which individuals value each role. Roles included provide expectations and/or opportunities for occupational behavior, such as student, worker, volunteer, care giver, home maintainer, friend, family member, religious participant, hobbyist/amateur, and participant in organizations. To assess reliability, we administered the checklist twice to a group of 124 normal volunteers ranging in age from 18 to 79. Values obtained for kappa and weighted kappa, measures of agreement that correct for chance agreement, suggested moderate or better agreement for Parts 1 and 2 of the checklist. We concluded, therefore, that the checklist has satisfactory test/retest reliability.

Assessment of Motor and Process Skills as a Measure of IADL Functioning in Pharmacologic Studies of People With Alzheimer's Disease: A Pilot Study

The purpose of this pilot study was to evaluate the usefulness of the Assessment of Motor and Process Skills (AMPS) as an outcome measure of instrumental activities of daily living (IADL) in pharmacologic studies of people with Alzheimers disease. The AMPS simultaneously measures motor and process skills and their effect on the ability of the person to perform familiar IADL tasks. We administered the AMPS to 11 Alzheimer inpatients in a 3 1/2-month, double-blind, placebo-controlled, crossover study of fluoxetine and selegiline administered as single agents and in combination with physostigmine. Results indicated that there was a significant difference in IADL ability among study conditions for process skills, but not for motor skills, thereby suggesting that the AMPS is useful as a sensitive outcome measure of IADL ability in drug trials with this population.

Differences in Activities of Daily Living Process Skills of Persons with and without Alzheimer's Disease

The purpose of this study was to determine if persons with dementia of the Alzheimer type (DAT) differed from nondisabled older controls in the actual, experienced difficulty of specific process skills that affect performance of activities of daily living (ADL). A two-group comparison was performed and all participants were evaluated in either clinical or home environments to which they had been familiarized. Participants (341 persons with DAT and 287 controls) were selected from the standardization sample of the Assessment of Motor and Process Skills (AMPS) computer-scoring software. The demographic characteristics of the two groups were comparable. The AMPS was used to evaluate the effort, efficiency, safety, and independence of 20 ADL process skills that are compiled to enact performance of familiar ADL tasks. The raw data for each sample was subjected to many-faceted Rasch analysis to determine item difficulty calibrations of the ADL process skill items for each group. Actual item difficulty calibrations of 19 ADL process skills differed meaningfully between the two groups. The results indicated that it is possible to identify specific ADL process skills that are actually easier or more difficult for each group. In addition, the results supported earlier research that has demonstrated that the underlying cognitive and physical impairments demonstrated by persons with DAT do manifest as ADL disability, negatively impacting their ability to perform ADL tasks.
