AI Insight
Researchers developed a 43-item scale to measure ideological-political literacy among Chinese university students across five dimensions: political identification, patriotic sentiment, moral cultivation, rule-of-law awareness, and cultural confidence. Using multidimensional item response theory with data from 3,716 students across 28 universities in 12 provinces, the final model demonstrated strong statistical fit and reliability scores ranging from 0.82 to 0.91. The scale showed measurement invariance across gender, grade level, and academic disciplines, though eight items displayed differential functioning across urban-rural and party-membership groups.
Why it matters
This instrument provides a standardized tool for assessing dimensions of civic and political attitudes among Chinese university students, which may inform educational policy and curriculum development. The rigorous psychometric validation offers a foundation for future research on ideological development in higher education contexts, though the authors caution that further independent validation is needed before operational use.
Understand the Science
IntroductionExisting measures of ideological-political literacy among Chinese university students have limited dimensional clarity and cross-group comparability. This study developed and evaluated a five-dimensional scale covering political identification, patriotic sentiment, moral cultivation, rule-of-law awareness, and cultural confidence using multidimensional item response theory.MethodsFramework-based qualitative coding, two-round Delphi consultation, content-validity screening, and pilot testing yielded 47 candidate items. A stratified cluster sample of 3,716 undergraduates from 28 universities across 12 provinces provided calibration data. A compensatory multidimensional graded response model (C-MGRM) was estimated by marginal maximum likelihood, with Metropolis-Hastings Robbins-Monro estimation as a same-sample robustness check. Competing dimensional specifications, reliability, measurement invariance, and differential item functioning (DIF) were examined.ResultsThe 47-item oblique model yielded RMSEA = 0.043, CFI = 0.957, and TLI = 0.951. After four items were removed, the final 43-item model yielded RMSEA = 0.039, CFI = 0.964, and TLI = 0.958; marginal reliabilities ranged from 0.82 to 0.91. Although bifactor models showed slightly better approximate fit, their indices did not support a substantive general-factor interpretation. Scalar invariance was reported across gender, grade, and disciplinary clusters. Eight items showed DIF across urban-rural or party-membership comparisons, leading to proposed wording revisions or interpretive caveats.DiscussionThe scale provides dimension-specific scores and a basis for further measurement development. Same-sample model selection, incomplete external-validity evidence, and unadjusted clustering in the MIRT and DIF analyses limit interpretation. Independent validation is needed, and the findings do not establish readiness for an operational computerized adaptive test.
