The literature posits that narcissism may theoretically influence online shopping addiction, with materialism being regarded as a consequence of narcissistic tendencies that subsequently exacerbate shopping addiction. Additionally, it is stated in the literature that age and gender are also associated with online shopping addiction. So, the present study aims to examine the effect of narcissism, age, and gender on online shopping addiction using the exhaustive CHAID analysis. In the research, which was designed as a survey and correlational study, data were collected from 1010 adults using the online shopping addiction scale and narcissism scale. The data obtained were analyzed with descriptive statistics and the exhaustive CHAID method. According to the analysis results, the participant group’s level of online shopping addiction was low, and their level of narcissism was moderate. In line with the results of the exhaustive CHAID analysis, the variables that most related to online shopping addiction were age, gender, and narcissism level. According to the analysis results, online shopping addiction decreases with advancing age. Women in younger age groups are more addicted to online shopping than men. Moreover, the increase in the level of narcissism is a condition that elevates the online shopping addiction of women in younger groups. It is reported in the literature that narcissism is more common in men and younger individuals. However, one of the most important study results is that, in this study, individuals with online shopping addiction are mostly relatively young female participants with high levels of narcissism.

文献认为，自恋在理论上可能会影响网上购物成瘾，物质主义被认为是自恋倾向的结果，随后加剧了购物成瘾。此外，文献中指出，年龄和性别也与网购成瘾有关。因此，本研究旨在利用详尽的 CHAID 分析来检验自恋、年龄和性别对网购成瘾的影响。这项研究是一项调查和相关研究，使用网购成瘾量表和自恋量表收集了 1010 名成年人的数据。使用描述性统计和详尽的 CHAID 方法对获得的数据进行分析。分析结果显示，参与群体的网购成瘾程度较低，自恋程度中等。与详尽的 CHAID 分析结果一致，与网购成瘾最相关的变量是年龄、性别和自恋水平。分析结果显示，网购成瘾随着年龄的增长而降低。年轻群体中的女性比男性更沉迷于网上购物。此外，自恋程度的增加也是导致年轻群体女性网购成瘾的一个因素。据文献报道，自恋在男性和年轻人中更为常见。然而，最重要的研究结果之一是，在这项研究中，网购成瘾者大多是相对年轻、自恋程度较高的女性参与者。
