The Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) is a caregiver-administered pain assessment checklist using direct observation and familiar caregiver information for the assessment of pain in elders with limited ability to communicate.

There are four subscales with a total of 60 items.
1) Facial expressions (13 items)
2) Activity/body movements (20 items)
3) Social/personality/mood (12 items)
4) Physiological indicators/eating and sleeping changes/vocal behaviors (15 items).

Each item is scored on a dichotomous scale by checking off those pain behaviors that are observed. The number of checks on each subscale are added together and recorded, then these sums are added together for a total score.

See reference for more information.
