Attitude Towards Pressure Ulcers Instrument: validação e adaptação transcultural para a população portuguesa de enfermeiros

Background and aim: Research and practice have shown the importance of nurses’s atitudes towards pressure ulcers prevention and the need for developing measurement instruments, valid and reliable for its evaluation. Responding to this need, have been performed a cross-cultural validation of the Attitude Towards Pressure Ulcers Instrument (APU) for the portuguese population. Methods: It was conducted a methodological study in a non-probabilistic sample of nursing students (n = 147) and nurses (n = 155). It was applyed the same methodology used in the original validation study. Results: The translation-back translation with the participation of a panel of experts ensured the conceptual and semantic equivalence. A fator analysis determined that 22 items are organized into five factors (importance, responsibility, obstacles / barriers, confidence in the effectiveness and personal skills), explaining 53.6% of the total variance. There was obtained a discriminating power of the scale in some of the groups compared. The overall a Cronbach coefficient= 0.847 assured scale's internal consistency and test-retest reliability revealed correlation coefficients r= 0.883, proving its temporal stability. Nurses and students showed a positive attitude towards the items of the scale, with no statistically significant difference between them (t = 0.567, p> 0.05). Conclusion: The APu-PT scale demonstrated to be reliable and valid for practice, teaching and research.
