Translation, Cross‐Cultural Adaptation and Content Validity Assessment of the Spanish Diabetes Management Knowledge Assessment Tool‐14 for Nursing Home Nurses

AIM: The aim of this study is to describe the initial phase of the psychometric validation process, specifically focusing on the translation, cross-cultural adaptation and content validation of the Diabetes Management Knowledge Assessment Tool-17 (DMKAT-17) for Spanish nursing home settings. DESIGN: Methodological study of translation, cross-cultural adaptation and content validation. METHOD: The translation and cultural adaptation process followed the ten steps recommended by Wild et al. Content validity was assessed using expert judgement and the modified Lawshe model proposed by Tristán-López. An expert panel evaluated the relevance of the items, and the content validity ratio and content validity index were calculated. RESULTS: The DMKAT-17 was reviewed by 13 experts. Based on expert ratings and qualitative feedback, items 1, 2 and 6 were removed, and wording changes were made to improve clarity and contextual appropriateness. This process resulted in a 14-item Spanish version (DMKAT-14). The scale-level content validity index was 0.841, indicating acceptable content validity based on expert judgement. PUBLIC CONTRIBUTION: This study provides a preliminary adapted Spanish version of the DMKAT-14 for the nursing home context and offers an initial basis for future psychometric evaluation.
