Psychometric Evaluation of the Revised Iowa Pain Thermometer-Czech for Patients with Stroke.

Background And Purpose: Pain is a frequent yet underdiagnosed problem in patients with stroke due to stroke-related cognitive limitations that may hamper effective usage of pain tools. The Revised Iowa Pain Thermometer-Czech (IPT-R-CZ) is a linguistically validated translation of an English-language self-report pain instrument; however, the psychometric properties of the Czech version are unknown. This study aimed to psychometrically evaluate the IPT-R-CZ in cognitively intact and impaired Czech-speaking patients with stroke.

Methods: Fifty-four patients rated their pain intensity using the IPT-R-CZ, the Faces Pain Scale-Revised, and the Numerical Rating Scale, ranking them in terms of usability.

Results: Correlations among pain scores across the tools were very strong. The IPTR-CZ ranked first in terms of usability.

Conclusion: Convergent validity, test-retest reliability, and usability of the IPT-R-CZ in Czech-speaking cooperative patients with stroke were acceptable.
