Background: Dementia, a global health concern affecting over 55 million people, demands increased awareness and education, particularly among diverse caregivers. The 27-item Dementia Knowledge Assessment Scale (DKAS) is a reliable tool, developed in 2015, validated for assessing dementia knowledge. Subsequent confirmatory factor analysis solidified its applicability in diverse populations. The DKAS goes beyond biological aspects, exploring psychosocial dimensions of dementia. The 20-item Dementia Attitudes Scale (DAS), established in 2010, exhibits a two-factor structure and is validated for research purposes. This protocol will guide a systematic review that aims to explore the extent and variety of adapted DKAS and DAS versions in existing literature.Methods: A three-step systematic literature search will be conducted on medical databases including PubMed, Medline, PyschINFO, Cochrane Library, and CINAHL. The keywords will include search terms such as Dementia; Alzheimer; Knowledge; Attitudes; DKAS; DAS. Two reviewers will independently assess studies based on the eligibility criteria, extracting information on characteristics of the studies, along with details about the procedures of translation of the DKAS and the DAS, the sample and administration, ethical approval, and statistical analysis. The results will be synthesised qualitatively in a narrative format. Results: This research highlights the importance of understanding adapted versions of the DKAS and DAS. Anticipated challenges in this systematic literature review include dealing with the heterogeneity of adaptations and potential language barriers, which may impact the synthesis of findings and generalizability.Conclusion: Investigating the psychometric properties of these adaptations is crucial for enhancing credibility, allowing for cross-cultural comparisons and targeted strategies to improve dementia knowledge and attitudes among specific groups.
