Evaluating Problematic Smartphone Use Among Chinese Primary School Students Using SABAS: An IRT and Network Analysis.
Article in International journal of methods in psychiatric research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study assessed the psychometric properties of the Smartphone Application-Based Addiction Scale (SABAS) among Chinese primary school students, focusing on validity, reliability, and factor structure using Item Response Theory (IRT) and Network Analysis (NA).
methodsData were collected from 1108 primary school students in China (52.98% female; ages 7-14 years; M = 10.58, SD = 0.99). SABAS was assessed using Item Response Theory (IRT) for factor structure, item parameters, cut-off scores, and reliability, while Differential Item Functioning (DIF) detected gender biases. Network Analysis (NA) examined the interrelationships among SABAS items.
resultsConfirmatory factor analysis supported SABAS's unidimensional structure (RMSEA = 0.055, CFI = 0.984, TLI = 0.973, SRMR = 0.025). IRT indicated high item discrimination (α = 1.47-2.47) and identified a cut-off score of 27, classifying 1.7% of students as high-risk for problematic smartphone use. Gender DIF was noted in item 6, with boys showing higher relapse tendencies (p < 0.05). NA highlighted the centrality of tolerance and withdrawal items.
conclusionsSABAS is a reliable tool for assessing problematic smartphone use in Chinese primary school students, particularly those at moderate to high risk.
