Summary
The Activity Management Inventory for Pain (AMI-P) is a new, reliable, and valid measure for chronic pain patients. It assesses activity management behaviors and goals, aiding research consistency.
Area of Science:
- Psychology
- Rehabilitation Medicine
- Pain Management
Background:
- Activity management is crucial for chronic pain programs, but existing measures have limitations.
- These limitations lead to inconsistencies in research findings on activity management in chronic pain.
Purpose of the Study:
- To develop and validate a new instrument, the Activity Management Inventory for Pain (AMI-P).
- To address the shortcomings of existing measures for assessing activity management in chronic pain.
Main Methods:
- The Activity Management Inventory for Pain (AMI-P) was developed by international experts in chronic pain and activity management.
- Initial evaluation involved two studies conducted in Canadian tertiary pain care centers.
Main Results:
- The 20-item AMI-P includes 3 behavior scales (Rest, Alternating Activity, Planned Activity) and 4 goal scales.
- Behavior scales showed good reliability and validity, correlating with existing measures and patient outcomes (pain interference, social satisfaction, depressive symptoms).
- The Alternating Activity scale improved significantly from pre- to post-treatment, and goal scales related to behavior scales.
Conclusions:
- The AMI-P scales demonstrate reliability and validity for assessing activity management in chronic pain.
- The findings underscore the complex, multidimensional nature of activity management in chronic pain populations.
