A two-step methodology was used to estimate the prevalence of dual diagnosis among persons participating in community-based day programs in the Chicago metropolitan area. In Step 1, a dual diagnosis screening test was administered to a random sample of 205 people with mental retardation. In Step 2, 59 subjects were evaluated by clinical psychologists who did not know the results of the screening test. The results consistently suggested very high rates, with the best data suggesting an overall rate of about 39%. The rates were high primarily because personality disorders were very common. The fact that only 11.7% of the subjects had a psychiatric diagnosis in their case files suggests that dual diagnosis was underdiagnosed for this sample.
采用两步法来估计参与芝加哥大都市地区社区日间项目的人群中双重诊断的患病率。第一步，对205名智力障碍者的随机样本进行双重诊断筛查测试。第二步，由不知道筛查测试结果的临床心理学家对59名受试者进行评估。结果始终显示出非常高的比例，最佳数据表明总体比例约为39%。比例高主要是因为人格障碍非常普遍。病例档案中只有11.7%的受试者有精神科诊断这一事实表明，该样本的双重诊断存在诊断不足的情况。
