The aim of this pilot study was to compare a German (Bavaria) and an American (North Dakota) sample of women suffering from compulsive buying.
Thirty-eight German and 39 American female compulsive buyers were screened with the Compulsive Buying Scale (CBS), and the Yale-Brown Obsessive Compulsive Scale-Shopping Version (Y-BOCS-SV) prior to entering a group treatment study. Psychiatric co-morbidity was assessed with the Structured Clinical Interview for DSM-IV Axis I disorders (SCID).
There were no statistically significant differences between the German sample and the American sample with regard to age (mean 43.7 and 45 years, respectively), and with regard to the scores on the CBS and the Y-BOCS-SV. A high lifetime co-morbidity rate with Axis I disorders, especially mood disorders, anxiety disorders, substance use disorders, OCD, and binge eating disorder was detected in both samples. Almost all participants met criteria for at least one lifetime Axis I disorder. However, German compulsive buyers showed significantly higher current prevalence rates of any affective disorder, and higher current and lifetime prevalence rates of any anxiety disorder and somatoform disorder. In addition, German compulsive buyers were significantly more likely to have more than one Axis I disorder.
The groups did not differ with regard to age and with regard to the severity of compulsive buying and showed a high co-morbidity with Axis I disorders. However, the German compulsive buying sample presented with significantly more psychiatric co-morbidity compared to the American sample. Further research is needed to provide a better understanding of this disorder in general and cross-culturally.
本试点研究旨在比较德国（巴伐利亚州）和美国（北达科他州）患有强迫性购买行为的女性样本。
38名德国和39名美国女性强迫性购买者在进入团体治疗研究之前，接受了强迫性购买量表（CBS）和耶鲁-布朗强迫量表购物版（Y-BOCS-SV）的筛查。使用《精神疾病诊断与统计手册》第四版轴I障碍结构化临床访谈（SCID）评估精神共病情况。
德国样本和美国样本在年龄（分别为平均43.7岁和45岁）以及CBS和Y-BOCS-SV得分方面没有统计学上的显著差异。在两个样本中均检测到与轴I障碍的高终生共病率，尤其是情绪障碍、焦虑障碍、物质使用障碍、强迫症和暴饮暴食障碍。几乎所有参与者都符合至少一种终生轴I障碍的标准。然而，德国强迫性购买者显示出任何情感障碍的当前患病率显著更高，以及任何焦虑障碍和躯体形式障碍的当前和终生患病率更高。此外，德国强迫性购买者更有可能患有不止一种轴I障碍。
两组在年龄以及强迫性购买行为的严重程度方面没有差异，并且与轴I障碍有较高的共病率。然而，与美国样本相比，德国强迫性购买样本的精神共病情况明显更多。需要进一步研究以更好地从总体上和跨文化角度理解这种障碍。
