ABSTRACT

Objective

To validate the Pain Assessment Checklist for Seniors with Limited Ability to Communicate – Portuguese in demented elderly and to analyze its measurement properties.

Methods

We evaluated 50 elderly with dementia, residing in a nursing home and with limited communication ability, when exposed to potentially painful situations. The tool was applied at two different moments. First, two interviewers applied it simultaneously, and the intensity of pain was asked based on the caregiver’s opinion. After 14 days, with no analgesic intervention, one of the interviewers applied it again.

Results

The sample comprised more females, aged over 80 years, with dementia due to Alzheimer, presenting musculoskeletal pain of moderate to severe intensity. The psychometric properties of the tool demonstrated appropriate internal consistency (Cronbach’s alpha coefficient of 0.827). The scale had excellent reproducibility, according to the intraclass correlation coefficient, and the tool has been duly validated.

Conclusion

The Pain Assessment Checklist for Seniors with Limited Ability to Communicate – Portuguese had adequate measuring properties for use with elderly presenting limited communication.
