Resumen

Aim: To evaluate the reliability and validity of an instrument that allows to measure the visual ability to identify and classify Incontinence Associated Dermatitis (IAD), Pressure Ulcers (PU) and mixed lesions, by nursing professionals. Material and method: A self-administered instrument consisting of 14 photographs was applied to a convenience sample of 28 nurses. A set of 14 photographs were shown in which they were asked to identify and then classify the state of the lesion. In an exploratory manner, the nested reliability was calculated with Cronbach’s Alpha and the validity with Principal Component Analysis (PCA). Results: The initial reliability of the 14 photographs was low (Cronbach Alpha = 0.174), after removing 7 photographs the reliability became acceptable (Cronbach Alpha = 0.709). The presence of two dimensions was established: on the one hand the ability to diagnose IAD, which explains 35% of the variance, and secondly, the ability to diagnose PU, which explains 22% of the variance, whether they are separated or together in the same patient. IAD is better diagnosed than mixed lesions. Conclusion: The study provided 6 reliable and valid photos that can be used in future work to build a more robust instrument that can be used in Chile for training in the area. The studied sample shows strengths when diagnosing IAD and difficulties when diagnosing mixed lesions.
