The authors explored the family history and psychiatric comorbidity of a group of compulsive buyers who volunteered for medication studies. Compulsive buying is characterized by inappropriate shopping and spending behavior that leads to impairment.
Thirty-three subjects who met the criteria of McElroy and colleagues for compulsive buying, and who scored more than two standard deviations above the mean on the Compulsive Buying Scale, were recruited. Twenty-two comparison subjects were recruited in the course of another study, and the presence of obsessive-compulsive disorder was the only reason for exclusion. Both groups were administered the Structured Clinical Interview for DSM-III-R disorders. The Family History Research Diagnostic Criteria were used to collect information about psychiatric disorders in first-degree relatives.
Compulsive buyers had a mean age of 40 years; two (6%) were men. Comparison subjects had a mean age of 39 years; six (27%) were men. The two groups differed in gender distribution but not in age, marital status, or educational achievement. Compulsive buyers were more likely than comparison subjects to have lifetime mood disorders (especially major depression) and to have more than one psychiatric disorder. First-degree relatives of compulsive buyers were more likely than comparison relatives to suffer from depression, alcoholism, and a drug use disorder and to suffer more psychiatric disorders in general.
These results indicate that persons who report compulsive buying behavior, and their first-degree relatives, are more likely to have a higher prevalence of psychiatric disorder than are comparison subjects.
作者探究了一组自愿参加药物研究的强迫性购买者的家族史和精神疾病共病情况。强迫性购买的特征是不适当的购物和消费行为，会导致功能损害。
招募了33名符合麦克尔罗伊及其同事制定的强迫性购买标准、且在强迫性购买量表上得分高于平均值两个标准差以上的受试者。在另一项研究过程中招募了22名对照受试者，排除标准仅为患有强迫症。两组均接受了针对DSM-III-R障碍的结构化临床访谈。使用家族史研究诊断标准收集一级亲属精神疾病的信息。
强迫性购买者的平均年龄为40岁；两名（6%）为男性。对照受试者的平均年龄为39岁；六名（27%）为男性。两组在性别分布上存在差异，但在年龄、婚姻状况或教育程度方面无差异。与对照受试者相比，强迫性购买者一生中更易患情绪障碍（尤其是重度抑郁症），且患有不止一种精神疾病。强迫性购买者的一级亲属比对照受试者的亲属更易患抑郁症、酒精中毒和药物使用障碍，总体上患精神疾病的情况更多。
这些结果表明，报告有强迫性购买行为的人及其一级亲属比对照受试者更易患精神疾病。
