Validation and Reliability Assessment of the Indonesian Version of the Self-Care Behaviour Instrument for Haemodialysis With Arteriovenous Fistula.

BACKGROUND: Arteriovenous fistula is a vascular access commonly used for long-term haemodialysis because of its durability and lower complication rate. Adequate self-care is essential, as poor self-care may lead to thrombosis, infection, and early access failure. Currently, Indonesia lacks a validated instrument to measure specific self-care behaviours. OBJECTIVE: This study aims to adapt and translate the Assessment of Self-Care Behaviours with Arteriovenous Fistula instrument into Indonesian and to evaluate its psychometric properties among patients receiving haemodialysis in Indonesia. DESIGN: Cross-sectional validation study. PARTICIPANTS: This study included 160 patients undergoing haemodialysis using an arteriovenous fistula. MEASUREMENT: The cross-cultural adaptation process followed internationally recognised guidelines. Content validity was evaluated by experts using the Item Content Validity Index and Scale Content Validity Index. Construct validity was examined using Exploratory Factor Analysis. Reliability testing was conducted using Cronbach's α coefficient. RESULTS: All 16 items demonstrated satisfactory content validity. The Kaiser-Meyer-Olkin value was 0.815, and Bartlett's test was significant (p < 0.001), confirming data suitability for factor analysis. Exploratory factor analysis identified a two-factor structure explaining 55.04% of the total variance, representing management of signs and symptoms and prevention of complications. The overall scale showed excellent internal consistency (α = 0.902), with α values of 0.902 and 0.833 for Factors 1 and 2, respectively. CONCLUSIONS: The Indonesian version of the Assessment of Self-Care Behaviours with Arteriovenous Fistula scale is valid and reliable in assessing self-care behaviours among patients receiving haemodialysis with arteriovenous fistula in Indonesia.
