Activity Measure for Post Acute Care (AMPAC)/ Participation Measure for Post Acute Care.

Haley, S.
Project title: 
Rehabilitation Research and Training Center on Measuring Rehabilitation Outcomes: Develop and Evaluate Activity Measures of Therapeutic Interventions across Rehabilitation Outcomes.
Project Number: 
Tool type: 
Tool class: 
Nonengineering tool
Disability targeted: 
All disabilities
Study target: 
People receiving medical rehabilitation services
Study purpose or goal: 
To learn how many activities can a person do and how many they recover once they return to community. Same with participation: how many people go back to important life roles after rehabilitation.
Who administers this tool?: 
Providers of medical rehabilitation services. It can also be self-reported.
Ease of use: 
Very easy
Time to complete: 
Equipment required: 
Sensitive issues: 
While there are no sensitive issues, per se, it does ask how many friends the subject has and collects income data to gauge socioeconomic status.
Are any approvals required?: 
The assessments received IRB approval.
How is it administered?: 
These measures are applied by medical rehabilitation professionals utilizing multiple venues: interview, computer-based forms, and self-reporting. Confidentiality is maintained by eliminating names during data processing. Researchers are developing a manual which will include scoring instructions.
What is the scope or what areas does it cover?: 
The Activity Measure covers three major components: physical function (navigating the environment), applied cognitive (communicating, write/read, scheduling day), and personal and instrumental care (dishes, laundry, etc). The Participation Measure, while still in development, covers two major areas: daily living activities at home (organizing home and finances, managing repairs) and community-based activities outside of home (visits with friends and social contacts, travel, voting, community events, volunteers, work). There will be multiple iterations of these measures: the short form will include no more than ten items. The computerized version will include six or seven items with questions chosen based on previous responses.
Development background: 
Development of these two assessment tools included extensive literature review in outcomes and measures design, as well as rehabilitation outcomes.
Development methodology: 
Questions and methodology were selected based on consumer input and tools existing in the field. The scales were field tested and questions were omitted or edited as necessary.
Outside consultation: 
Consultations were made with researchers within and outside the institution.
Consumer input: 
Consumer input was gathered through focus groups, including an focus group within the RRTC and disability-specific support groups in the community at large.
Can this tool be used for other purposes/populations?: 
The assessment is specific to the purpose: for rehabilitation providers to monitor quality of care by understanding which people recover and which do not. The development process evaluates facets of life during the rehabilitation process.
Sample type: 
The original sample included a broad spectrum of participants.
Data analysis: 
Is in process
While there are no limitations to the tool itself, the researchers were limited in their original sample size
Publication of results is pending in 2004.
These instruments will allow rehabilitation providers to collect data more easily across the rehabilitation setting and make quality improvements in care.
Research methods: 
Multiple data analysis techniques were utilized with item response theory predominating.
