Psychometric evaluation of the study interest questionnaire-short form among Chinese nursing students based on classical test theory and item response theory.
Article in BMC nursing, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
backgroundThere is currently no dedicated measurement for assessing nursing students' study interest in China. Considering the good reliability, validity, and widespread applicability of the Study Interest Questionnaire-Short Form (SIQ-SF), the objective of this study was to validate its usage among Chinese nursing students.
methodsThe translation and cross-cultural adaptation rigorously followed the modified Brislin model. A cross-sectional survey was conducted using the Chinese version of the SIQ-SF and convenience sampling was employed to select nursing students. The Psychometric evaluation of the Chinese version of the SIQ-SF was conducted based on Classical Test Theory and Item Response Theory.
resultsA total of 1158 participants were included in the analysis. The item-level content validity index (CVI) ranged from 0.9 to 1.0, and the scale-level CVI was 0.98. In the Exploratory factor analysis, three factors with eigenvalues above 1 were identified, accounting for 62.554% of the cumulative variance. In the confirmatory factor analysis, the CMIN\DF was 5.639, the GFI was 0.953, the CFI was 0.902, and the IFI was 0.904. The Cronbach's α coefficient of the Chinese version of the SIQ-SF was 0.70. Thirty-one participants were invited to sign the scale after two weeks. The intraclass correlation coefficient was 0.784, and that of items ranged from 0.70 to 0.819. The infit MnSQ values ranged between 0.76 and 1.51, and the outfit MnSQ values ranged between 0.72 and 1.76. The point-measure correlation value ranged between 0.30 and 0.68. The item difficulty measures ranged from - 0.66 to 1.44 logit and the individual learning interest estimations ranged from - 4.22 to 4.97 logit. DIF contrast ranged from 0.00 to 0.33 logits, with all p values greater than 0.05.
conclusionsThe Chinese version of the SIQ-SF demonstrated acceptable reliability and validity among Chinese nursing students and could be used to assess nursing students' study interest in China. With the aid of this scale, teachers can gain a better understanding of nursing students' study interests, thereby maximizing their learning effects through appropriate content and methods.
