Social Network Site Use Motives Scale (SUMS) was developed under the assumption that it consists of six factors, but only four factors were extracted as a result of Exploratory Factor Analysis. The goal of the present study was to investigate whether SUMS consists of four or six factors using Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM) approach.
A Korean college student sample (n=600; mean age, 21 years; 58% female) filled out the SUMS and the Social Network Site Addiction Proneness Scale. CFA and ESEM were used to assess the factor structure of the SUMS.
Results indicated that a four-factor solution to the SUMS had inadequate fit in the sample examined using both CFA and ESEM and a six-factor solution to the SUMS had insufficient fit using CFA, whereas fit was optimal using ESEM for the six-factor model. In addition, the scale showed adequate convergent validity and reliability.
These findings support the six-factor model of SNS use motives and suggest that ESEM is a more appropriate method than CFA for examining the factor structure of the SUMS. The results displayed the usefulness of the ESEM framework in the investigation of use motives.
社交网站使用动机量表（SUMS）是在假设它由六个因素组成的情况下编制的，但探索性因素分析的结果仅提取出四个因素。本研究的目的是使用验证性因素分析（CFA）和探索性结构方程模型（ESEM）方法来调查SUMS是由四个还是六个因素组成。
一个韩国大学生样本（n = 600；平均年龄21岁；58%为女性）填写了SUMS和社交网站成瘾倾向量表。使用CFA和ESEM来评估SUMS的因素结构。
结果表明，SUMS的四因素模型在所检查的样本中使用CFA和ESEM时拟合度不足，SUMS的六因素模型使用CFA时拟合度不足，而使用ESEM时六因素模型的拟合度最佳。此外，该量表显示出足够的收敛效度和信度。
这些发现支持社交网络服务使用动机的六因素模型，并表明对于检查SUMS的因素结构，ESEM是比CFA更合适的方法。结果显示了ESEM框架在使用动机调查中的有用性。
