青少年智能手机使用动机的初步编制（英文）

Development of a Motivation for Smartphone Use Scale for Adolescents

本研究旨在编制智能手机使用动机量表,并对其信效度进行检验。将847名被试分为两组,第一组进行探索性因素分析,评估问卷信度,第二组进行验证性因素分析,评估问卷结构效度。根据探索性因素分析获得六个因子:娱乐,辅助生活,自我表达,人际交往,辅助学习和打发时间。总量表以及各分量表的α系数为0.76~0.94。根据验证性因素分析,对模型进行修改,允许条目16和条目17的误差相关,修改后除TLI和CFI值,其他指标值较满意,因此该量表可以用来测量青少年手机使用动机情况。

The aim of this study was to develop a motivation for smartphone use scale（MSUS） and evaluate the reliability and construct validity of the scale. There were two sample groups that consisted of 847 adolescents in the research. The first sample group was used to conduct EFA and estimate the reliability of the questionnaire, and the second sample group was used to confirm the factor structure of the scale through CFA. The model fit indices of EFA indicated that the six-factor structure was acceptable： entertainment, assisting live, self-expression, interpersonal communication, assisting study and pastime. The internal consistency of the overall scale and subscales was assessed using cronbach＇ s alpha, and the values ranged from 0.76 to 0.94. The results of CFA indicated the structure of the scale should be amended through allowing the correlation between error values of item 16 and item 17. Though TLI and CFI values were not perfect, but other indexes were satisfactory. Therefore, with limited exception, the MSUS was reliable and valid in the context of adolescents.
