This 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).
Data 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.
Confirmatory 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.
SABAS is a reliable tool for assessing problematic smartphone use in Chinese primary school students, particularly those at moderate to high risk.
本研究评估了基于智能手机应用的成瘾量表（SABAS）在中国小学生中的心理测量特性，重点使用项目反应理论（IRT）和网络分析（NA）来检验效度、信度和因子结构。
收集了来自中国1108名小学生的数据（女生占52.98%；年龄7 - 14岁；M = 10.58，SD = 0.99）。使用项目反应理论（IRT）评估SABAS的因子结构、项目参数、临界分数和信度，同时用差异项目功能（DIF）检测性别偏差。网络分析（NA）研究SABAS项目之间的相互关系。
验证性因子分析支持SABAS的单维结构（RMSEA = 0.055，CFI = 0.984，TLI = 0.973，SRMR = 0.025）。IRT表明项目具有较高的区分度（α = 1.47 - 2.47），并确定临界分数为27，将1.7%的学生归类为智能手机使用问题的高风险人群。在第6项中发现了性别差异项目功能，男孩表现出更高的复发倾向（p < 0.05）。NA突出了耐受性和戒断项目的中心性。
SABAS是评估中国小学生智能手机使用问题的可靠工具，尤其适用于中高风险学生。
