Translation, Cross-Cultural Adaptation and Content Validity Assessment of the Spanish Diabetes Management Knowledge...

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.

Methodological study of translation, cross-cultural adaptation and content validation.

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.

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.

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.
