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

TL;DR

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.

Key Findings

All 16 items of the Indonesian-adapted instrument demonstrated satisfactory content validity as evaluated by expert reviewers.

  • Content validity was evaluated using the Item Content Validity Index (I-CVI) and Scale Content Validity Index (S-CVI)
  • All 16 items met the threshold for satisfactory content validity
  • The cross-cultural adaptation process followed internationally recognised guidelines
  • Expert panel review was used to assess relevance and appropriateness of each item

The data were confirmed as suitable for factor analysis based on the Kaiser-Meyer-Olkin measure and Bartlett's test of sphericity.

  • Kaiser-Meyer-Olkin (KMO) value was 0.815, indicating sampling adequacy
  • Bartlett's test of sphericity was statistically significant (p < 0.001)
  • Both values confirmed the appropriateness of the dataset for Exploratory Factor Analysis (EFA)
  • The study included 160 patients undergoing haemodialysis with an arteriovenous fistula

Exploratory Factor Analysis identified a two-factor structure for the 16-item Indonesian instrument.

  • The two-factor solution explained 55.04% of the total variance
  • Factor 1 represented 'management of signs and symptoms'
  • Factor 2 represented 'prevention of complications'
  • The factor structure emerged from analysis of 160 haemodialysis patients

The Indonesian version of the scale demonstrated excellent internal consistency reliability overall and for each subscale.

  • Overall scale Cronbach's α = 0.902, indicating excellent internal consistency
  • Factor 1 (management of signs and symptoms) Cronbach's α = 0.902
  • Factor 2 (prevention of complications) Cronbach's α = 0.833
  • All reliability values exceeded the commonly accepted threshold of 0.70

The study was conducted in a cross-sectional design among haemodialysis patients in Indonesia using an arteriovenous fistula as vascular access.

  • Sample size was 160 patients undergoing haemodialysis with an arteriovenous fistula
  • Cross-sectional validation study design was employed
  • Arteriovenous fistula is described as a vascular access commonly used for long-term haemodialysis 'because of its durability and lower complication rate'
  • Indonesia previously lacked a validated instrument to measure specific self-care behaviours for this population

What This Means

This research describes the translation and validation of a self-care assessment tool for people in Indonesia who undergo haemodialysis (kidney dialysis) using an arteriovenous fistula — a surgically created connection between an artery and vein used as a long-term access point for dialysis. Previously, no validated Indonesian-language instrument existed to measure how well these patients care for their fistula, which is important because poor self-care can lead to serious problems such as blood clots, infections, and early access failure. The researchers adapted an existing instrument into Indonesian following internationally recognised guidelines and tested it with 160 haemodialysis patients. The study found that all 16 items in the adapted tool had satisfactory content validity (meaning experts agreed the questions accurately measured what they were supposed to measure), and statistical testing confirmed the data were suitable for further analysis. Factor analysis revealed that the 16 questions grouped into two meaningful categories: managing signs and symptoms, and preventing complications. Together, these two factors explained about 55% of the variation in patient responses. The tool also showed excellent reliability, with Cronbach's alpha values of 0.902 for the overall scale and both subscales scoring above 0.83, well above accepted standards. This research suggests that the Indonesian version of this self-care instrument is both valid and reliable for use with haemodialysis patients in Indonesia. Having a culturally and linguistically appropriate tool means that healthcare providers and researchers in Indonesia can now systematically assess and monitor self-care behaviours in this patient population, potentially helping to identify patients who need more education or support in caring for their arteriovenous fistula and preventing complications.
