The purpose of this study is to assess the validity and reliability of general job satisfaction (JS) in the Korean Labor and Income Panel Study (KLIPS).
We used the data from the 17th wave (2014) of the nationwide KLIPS, which selected a representative panel sample of Korean households and individuals aged 15 or older residing in urban areas. We included in this study 7679 employed subjects (4529 males and 3150 females). The general JS instrument consisted of five items rated on a scale from 1 (strongly disagree) to 5 (strongly agree). The general JS reliability was assessed using the corrected item-total correlation and Cronbach's alpha coefficient. The validity of general JS was assessed using confirmatory factor analysis (CFA) and Pearson's correlation.
The corrected item-total correlations ranged from 0.736 to 0.837. Therefore, no items were removed. Cronbach's alpha for general JS was 0.925, indicating excellent internal consistency. The CFA of the general JS model showed a good fit. Pearson's correlation coefficients for convergent validity showed moderate or strong correlations.
The results obtained in our study confirm the validity and reliability of general JS.
本研究旨在评估韩国劳动与收入面板调查（KLIPS）中总体工作满意度（JS）的有效性和可靠性。
我们使用了全国性KLIPS第17轮（2014年）的数据，该调查选取了居住在城市地区、年龄在15岁及以上的韩国家庭和个人的代表性面板样本。本研究纳入了7679名就业受试者（4529名男性和3150名女性）。总体工作满意度量表由五个项目组成，评分范围为1（强烈不同意）至5（强烈同意）。使用校正后的项目与总分相关性和克朗巴哈α系数评估总体工作满意度的可靠性。使用验证性因素分析（CFA）和皮尔逊相关性评估总体工作满意度的有效性。
校正后的项目与总分相关性范围为0.736至0.837。因此，没有项目被剔除。总体工作满意度的克朗巴哈α系数为0.925，表明内部一致性极佳。总体工作满意度模型的CFA显示拟合良好。收敛效度的皮尔逊相关系数显示出中度或强相关性。
我们研究中获得的结果证实了总体工作满意度的有效性和可靠性。
