Pressure injury prevention in older people: construction and validation of an instrument for caregivers.

OBJECTIVES

to construct and validate an instrument to assess the knowledge, attitudes, and practices related to pressure injury prevention among caregivers of institutionalized older people.

METHODS

this is a three-stage methodological study that consisted of instrument construction, analysis by experts, and semantic and appearance analysis, with 78 participants, observing the validation process steps for psychometric instruments in the criteria of clarity and relevance.

RESULTS

in the Delphi I round, the validity index of the general content in the clarity criterion was 0.66, in relevance 0.85, and the Kappa value was >0.76. In Delphi II, clarity was 0.95, relevance 1.00, and the Kappa value was >0.97.

CONCLUSIONS

this is a valid instrument in terms of content and appearance, which allows further analysis of its reliability for the measurement of the constructs for which it is intended. Therefore, it can be considered a tool for care management in pressure injury prevention.
