University of Iowa, Iowa City, Iowa, United States  \nPain assessment in people with dementia is challenging and can result in inadequate treatment. Most pain assessment tools require subjective quantification of pain/discomfort. PainChek® is a new assessment tool that harnesses a) artificial intelligence to provide objective pain ratings of facial expression and b) dichotomous ratings of observable non-facial pain indicators. This study aimed to validate PainChek® by examining the agreement, reliability, and predictive validity between PainChek® and the Abbey Pain Scale (APS), a more subjective pain scale commonly used in Australia. Participants (N = 103) were US nursing home residents with moderate-to-severe cognitive impairment. Participants were assessed for pain during rest and post-movement by two blinded raters, each administering one pain assessment tool. Agreement between raters was 92.7%(no pain), 69.1%(mild), 75%(moderate), and 83.3%(severe), suggesting high levels of agreement between PainChek® and APS assessments. Agreement rates, except in the mild condition, exceeded a priori hypotheses and were similar across rest/post-movement conditions. Intraclass correlations show that PainChek® ( .73, 95% CI: .62-.81) outperformed APS (.59, 95% CI: .44-.71) on test-retest reliability. Bootstrapping methods yielded predictive values that were 75.5%, 89%, 82.8%, and 38.3% for no pain, mild, moderate, and severe. Low predictive value for severe pain was likely due to few occurrences of severe pain assessments. Results suggest that PainChek® performs on par with the APS, while providing a more objective format that enables greater accessibility for a variety of staff to administer reliably. Decreasing subjectivity from the pain assessment process may facilitate accuracy and lead to more appropriate treatment.","cbCaiu2BPeYtJ2TI","https://ap.wps.com/l/cbCaiu2BPeYtJ2TI","pdf",772312,"English","# Study Purpose\n## PainChek® Assessment Approach\n# Methods\n## Participants and Assessment Conditions\n## Blinded Raters and Tools\n# Results\n## Inter-Rater Agreement\n## Reliability and Predictive Validity\n# Conclusions\n## Objectivity and Clinical Implications","[{\"question\":\"Why is pain assessment difficult in people with dementia?\",\"answer\":\"Pain assessment in dementia is challenging and can result in inadequate treatment.
