There has been an increasing amount of research examining problematic shopping behavior (PSB), often referred to in the psychological literature as "compulsive buying" or "shopping addiction." A popular scale for assessing the risk of PSB is the seven-item Bergen Shopping Addiction Scale (BSAS). To expand our knowledge of the psychometric properties of this instrument, the present study employed Item Response Theory (IRT) and differential item functioning analyses (DIF) while concurrently attempting to determine a preliminary cut-off point. A relatively large community sample completed the BSAS online ( = 968, = 29.5 years, = 9.36, 32.5% women). IRT analyses showed differences regarding the BSAS items' discrimination, difficulty, and precision, with a raw score exceeding 23 (out of 28) indicating a higher risk of shopping addiction. Finally, while most BSAS items operated equally among males and females, Item 2 () required a higher level of shopping addiction behaviors to be endorsed by males. The BSAS functions as a reliable assessment of the risk of shopping addiction, particularly between average and high levels of the trait. Clinical implications are discussed in light of these findings.
对问题购物行为（PSB）的研究越来越多，在心理学文献中，这种行为通常被称为“强迫性购买”或“购物成瘾”。一种评估PSB风险的常用量表是七项的卑尔根购物成瘾量表（BSAS）。为了扩展我们对该工具心理测量特性的了解，本研究采用了项目反应理论（IRT）和项目功能差异分析（DIF），同时试图确定一个初步的临界点。一个相对较大的社区样本在线完成了BSAS（n = 968，M = 29.5岁，SD = 9.36，32.5%为女性）。IRT分析显示，BSAS项目在区分度、难度和精度方面存在差异，原始分数超过23分（满分28分）表明购物成瘾风险较高。最后，虽然大多数BSAS项目在男性和女性中的作用相同，但第2项（）需要男性认可更高水平的购物成瘾行为。BSAS可作为购物成瘾风险的可靠评估工具，尤其是在该特质的平均水平和高水平之间。根据这些发现讨论了临床意义。
