PurposePain assessment at the end of life remains a problem for patients who are unable to self-report their pain when transitioning across care settings. This study therefore tested the internal consistency and discriminant, concurrent, and convergent validity of the Critical-Care Pain Observational Tool (French version) when used with end-of-life patients in a palliative care setting.DesignThis was a descriptive correlational study that used a repeated-measures within-subjects prospective design.MethodsThe pain of 13 patients was assessed when at rest and during turning.ResultsThe internal consistency reliability coefficient alphas were .64 at rest and .70 during turning. Discriminant validity was shown by a decrease in the total Critical-Care Pain Observation Tool score. Concurrent validity was demonstrated by the association between the patients' self-report of pain and the Critical-Care Pain Observation Tool score at rest (0.65, p < .016) and during turning (0.77, p = .002). Finally, the convergent validity between the Critical-Care Pain Observation Tool score and the Algoplus scale score was demonstrated with a Spearman's correlation coefficient of 0.76 at rest and 0.84 during turning.ConclusionsThe results suggest that the Critical-Care Pain Observation Tool can be used with end-of-life patients in French-speaking countries.Copyright © 2020 American Society for Pain Management Nursing.
