There is a widespread phenomenon in current society where children are exposed to the internet at an early age and use electronic screens frequently. However, the academic community has not yet established a complete and clear operational definition of screen dependency behavior in preschoolers or developed effective behavioral identification tools. To address this issue, this study developed the Preschool Screen Dependency Behavior Scale for children aged 3–6 years. The study first recruited 21 parents of preschoolers to complete semi-structured interviews. Subsequently, a questionnaire survey was conducted, and the collected 633 valid parent responses were randomly divided into two groups: one group (n=333) for exploratory factor analysis and the other group (n=300) for confirmatory factor analysis and validity testing. The results showed that the Chinese Preschool Screen Dependency Behavior Scale (CPSD) consists of 9 items, comprising three factors: negative emotional resistance, physical function deterioration, and withdrawal difficulties. The confirmatory factor analysis model demonstrated fit indices (χ²/df= 3.02, RMSEA=0.077, CFI=0.875, TLI=0.922), with Cronbach’s α=0.903, indicating an acceptable reliability and validity of the questionnaire for measuring the degree of screen dependency behavior in 3–6-year-old preschoolers.

当前社会普遍存在儿童过早接触网络及高频使用电子屏幕的现象, 而学术界尚未建立完整且明确的幼儿屏幕依赖行为的操作性定义及有效的行为识别工具。针对这一情况, 编制学龄前幼儿(3~6岁)屏幕依赖行为量表。首先招募21名幼儿家长, 完成半结构化访谈; 随后采用问卷调查法, 将收集的633份有效家长问卷随机分成两组, 一组(n=333)用于探索性因素分析, 另一组(n=300)用于验证性因素分析和效度检验。最终编制的中国幼儿屏幕依赖行为量表(CPSD)有9个条目, 包含消极情绪对抗、身体机能弱化和使用退出障碍3个因子。验证性因素分析模型的拟合程度良好(χ²/df=3.02, RMSEA=0.077, CFI=0.875, TLI=0.922), Cronbach’s α=0.903, 说明问卷的信效度良好, 可用于测量3~6岁幼儿屏幕依赖行为程度。
