Abstract:

Objective To systematically evaluate the measurement properties and methodological quality of relevant studies of the Chinese version of the assessment tool for cognitive behavior of diet and nutrition among hemodialysis patients. Methods Databases were systematically searched，including CNKI，Wanfang，VIP，SinoMed，PubMed，Web of Science，Cochrane Library，Embase，and CINAHL. Time limit was set from the inception of the database to June 17，2024. After that，two researchers independently screened the literature and extracted data. The measurement properties and methodological quality of the included assessment tools were evaluated using the Consensus-based Standards for the Selection of Health Measurement Instruments（COSMIN），and final recommendations were formed. Results A total of 10 studies were included，involving 10 different assessment tools for cognitive behavior of diet and nutrition among hemodialysis patients. None of the tools has evaluated their hypothesis testing，cross-cultural validity，measurement error，or responsiveness. Due to high-quality evidence demonstrating that the content validity and internal consistency，the Nutritional Knowledge，Attitude，and Behaviour Questionnaire for Maintenance Hemodialysis Patients were rated as “adequate” which was recommended as Grade A. The other nine assessment tools were recommended as Grade B. Conclusion There are a number of Chinese versions of assessment tools for cognitive behavior of diet and nutrition among hemodialysis patients，with varying overall quality. Among them，the Nutritional Knowledge，Attitude，and Behaviour Questionnaire for Maintenance Hemodialysis Patients can be tentatively recommended for use，while the remaining tools require further validation in multiple measurement properties.
