METHODS: A structured methodological process will be employed to guide the instrument's development and subsequent validation. The instrument aims to encompass comprehensible questions with a simple scoring and interpretation mechanism to foster its daily use. The study will consist of two phases. Phase 1 focuses on the development of the Malaysian instrument. This phase encompasses a literature review, item development tailored to the Malaysian context, content validity through expert panel evaluations, translations, pre-tests and a follow-up stakeholder engagement to ensure the instrument meets their requirements. Incorporating perspectives from experts and comprehensibility by local patients ensures the instrument's relevance to the local context. Phase 2 involves instrument validation through a cross-sectional study. This phase entails a pilot test and field test of the instrument among diabetic patients for validation. Cut-off ranges and their interpretations will also be established in this phase. The study sites encompass a mix of urban and rural public health clinics across Peninsular as well as East Malaysia.
DISCUSSION: By developing a standard validated instrument to assess diabetic foot self-care practices, services provision gaps can be identified, and targeted interventions to improve these gaps in practices can be implemented. Individually tailored diabetes foot care education is crucial in preventing foot ulcers. This instrument can also facilitate the monitoring of improvements in patients' foot self-care practices longitudinally.
