Development and preliminary psychometric evaluation of an oral health questionnaire for chronic kidney disease (CKD-OHQ).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOral health problems are common among patients with chronic kidney disease. Chronic kidney disease is associated with a broad range of oral manifestations, while poor oral health may accelerate chronic kidney disease progression, increase the risk of complications, and contribute to the overall disease burden. Despite their clinical importance, oral health problems often receive limited attention in routine nephrology care. This study aimed to develop and conduct a preliminary psychometric evaluation of the Chronic Kidney Disease Oral Health Questionnaire to assess nephrology healthcare professionals' knowledge, attitudes, and self-reported practices regarding oral health management in patients with chronic kidney disease.
methodsThe initial questionnaire was developed using a knowledge-attitude-practice framework, a literature review, and two rounds of expert consultation. In October 2025, the preliminary questionnaire was administered online to nephrology healthcare professionals in Hubei, Anhui, and Jiangsu provinces, China. Content and face validity, internal consistency, and test-retest reliability were evaluated. Exploratory factor analysis was conducted to examine the construct validity of the attitude and practice dimensions.
resultsThe questionnaire comprised 25 items across three dimensions. A total of 169 valid responses were included. The scale-level content validity index was 0.95. Cronbach's α coefficients were 0.97 for the attitude dimension and 0.98 for the practice dimension, whereas the Kuder-Richardson Formula 20 coefficient for the knowledge dimension was 0.46. The intraclass correlation coefficient for the total questionnaire was 0.95. Exploratory factor analysis of the attitude and practice items identified two factors that explained 83.34% of the total variance.
conclusionsThe questionnaire offers a preliminary structured approach to assessing nephrology healthcare professionals' knowledge, attitudes, and self-reported practices regarding oral health management in patients with chronic kidney disease. The findings provide initial evidence of its measurement properties while indicating the need for further refinement and validation in larger, more diverse, and independently recruited samples before wider application.
