The Turkish Version of the Haemodialysis Self-Management Instrument: A Study of Validity and Reliability

This study aims to adapt the 'Hemodialysis Self-Management Instrument (HDSMI-18)' to Turkish culture, and evaluate its psychometric properties.

Self-management plays a critical role in improving patients' adherence to treatment and quality of life; however, self-management assessment tools specific to haemodialysis patients are limited.

The research employed a methodological design.

The data were collected with a total of 200 haemodialysis patients receiving haemodialysis treatment between 15 July and 15 August 2024. Content Validity Index, Exploratory and Confirmatory Factor Analyses, Cronbach's alpha, Test-retest reliability and item-total score correlation were used in data analysis.

The original HDSMI-18 consists of 18 items and four subdimensions (partnership, self-care, problem-solving, emotional management). However, the Turkish version of HDSMI-18 (HDSMI) comprises 17 items and introduces an additional fifth subdimension, 'self-control', alongside the four original subdimensions. The five-factor structure of the HDSMI demonstrated acceptable internal consistency and reliability. The scale's overall Cronbach's α coefficient was determined to be 0.77, with subscale coefficients ranging from 0.63 to 0.83.

The HDSMI is a valid and reliable tool for assessing self-management behaviours among haemodialysis patients in the Turkish population.
