In the present study, the Turkish version of the Craving for Online Shopping Scale (TCOSS) was developed by modifying items on the Penn Alcohol Craving Scale (PACS). The sample comprised 475 adult volunteers (233 women and 242 men) from three different non-clinical samples recruited online. The structure validity of the TCOSS was examined utilizing exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and criterion validity testing. The EFA showed that the TCOSS had a unidimensional structure that explained 80% of the total variance. The five-item unidimensional structure of the TCOSS then underwent further testing using two different samples. First, the structure of the TCOSS was tested using CFA, which confirmed the unidimensional factor structure. Second, measurement invariance of the TCOSS was conducted through structural invariance, metric invariance, and scalar invariance across different samples. This demonstrated the TCOSS had measurement invariance across different samples (CFA and criterion validity samples). Criterion validity of the TCOSS was tested using the Internet Addiction Test-Short Form, Brief Self-Control Scale, Compulsive Online Shopping Scale, Positive and Negative Affect Schedule, and self-reported personal information. According to the criterion validity results, the TCOSS assessed the structure it targets. Cronbach’s α internal consistency coefficients of the TCOSS were .94 in the EFA sample, .94 in the CFA sample, and .96 in the criterion validity sample. When validity and reliability analysis of the TCOSS are considered as a whole, it is concluded that the TCOSS is a valid and reliable scale for assessing craving for online shopping among online shoppers.

在本研究中，土耳其语版本的网上购物渴望量表（TCOSS）是通过修改Penn酒精渴望量表（PACS）上的项目而开发的。该样本包括来自在线招募的三种不同的非临床样本中的475名成人志愿者（233名女性和242名男性）。使用探索性因子分析（EFA），确认性因子分析（CFA）和标准有效性测试对TCOSS的结构有效性进行了检查。EFA表明，TCOSS具有一维结构，可解释总差异的80％。然后，使用两个不同的样品对TCOSS的五项一维结构进行了进一步测试。首先，使用CFA对TCOSS的结构进行了测试，这证实了一维因子结构。第二，TCOSS的测量不变性是通过不同样本之间的结构不变性，度量不变性和标量不变性进行的。这表明TCOSS在不同样本（CFA和标准有效性样本）之间具有测量不变性。使用互联网成瘾测试简表，简短的自我控制量表，强迫性在线购物量表，正面和负面影响表以及自我报告的个人信息对TCOSS的标准有效性进行了测试。根据标准有效性结果，TCOSS评估了其目标结构。EFA样本中TCOSS的Cronbach'sα内部一致性系数为0.94，CFA样本中为0.94，标准效度样本中为0.96。当从整体上考虑TCOSS的有效性和可靠性分析时，
