Objective: to translate, evaluate the reliability and cross-culturally adapt the Skin Management Needs Assessment Checklist, a questionnaire evaluating the knowledge on pressure ulcer prevention measures in persons with spinal cord injury. Study design: Cross-cultural adaptation and reliability study. Subjects: 138 persons with spinal cord injury, mean age 45.9 years, mean time since injury 94 months. Material and method: The study was carried out in 2 stages. First, the questionnaire went through a forward-backward translation process and was cross-culturally adapted, according to a validated methodology for self-reported measures. Then, the test-retest reliability was evaluated on a population of persons with spinal cord injury Results: The standardized back-translation and cross-cultural adaptation led to the revised Smack grid, with the addition of 7 items representing an update of pressure ulcer prevention measures. The reliability was excellent (intraclass correlation coefficient: 0.899). Conclusion: The revised SMnac is an adaptation of the SMnac, including therapeutic education frameworks and the latest pressure ulcer prevention practices. It appears to be a reliable tool for assessing the knowledge and benefits of pressure ulcer prevention in persons with spinal cord injury. Further studies are needed to explore its validity and responsiveness to change. Keywords: knowledge, education, prevention, spinal cord injury, weight pressure relief, behaviors
