项目摘要

DESCRIPTION (provided by applicant): Mood disorders are among the most common and debilitating conditions affecting humanity. Correctly identifying and treating mood disorders is critical in order to address this serious public health problem. However, African-Americans with mood disorders are significantly more likely than white patients to be misdiagnosed with schizophrenia. Consequently, African-Americans are at increased risk for receiving inadequate treatment. Failure to correctly identify African-Americans with these conditions contributes to disparities in medical care delivery between ethnic minority and majority patients. However, it is not known why African-Americans with mood disorders are more likely than whites to be misdiagnosed with schizophrenia. Previous investigators suggested that misdiagnoses of schizophrenic disorders appeared to occur because clinicians failed to elicit affective symptoms from African-Americans with mood disorders. Moreover, when mood and psychotic symptoms were both identified, clinicians appeared to minimize the affective symptoms in African-American men. These findings suggest the hypothesis that African-Americans with severe mood disorders are more likely than whites to be misdiagnosed with schizophrenia because clinicians over-emphasize psychotic symptoms at the expense of mood symptoms in the former. Consistent with this hypothesis, African- Americans are more likely to receive excess antipsychotics. Previous studies typically contrasted only African- American and white patients, so it is unknown whether this problem of misdiagnosis is unique to African-Americans or also occurs in other U.S. minorities. Although some studies reported that mood disorders were also commonly misdiagnosed as schizophrenia in Latinos, other work disagreed. Because there are few studies of these issues in Latinos, it is difficult to identify associations among diagnosis, treatment and ethnicity in this patient group. With these considerations in mind, we propose a large, regionally diverse, six-site collaborative R01 study to examine the effects of ethnicity on clinical diagnosis and treatment assignment in African-American, Latino and white patients with mood disorders. The primary objective is to test the hypothesis that clinicians over-emphasize psychotic symptoms at the expense of affective symptoms in African-Americans, leading to an excess of clinical diagnoses of schizophrenia relative to other ethnic groups. A second objective is to test the hypothesis that over-emphasis of psychotic symptoms also contributes to increased antipsychotic use in African-Americans. The final objective is to determine whether Latinos are at risk for similar problems in diagnostic assessments and treatment assignment.

描述（由申请人提供）：情绪障碍是影响人类的最常见和最衰弱的疾病之一。正确识别和治疗情绪障碍对于解决这一严重的公共卫生问题至关重要。然而，患有情绪障碍的非裔美国人被误诊为精神分裂症的可能性明显高于白色患者。因此，非洲裔美国人接受治疗不足的风险增加。未能正确识别患有这些疾病的非洲裔美国人导致少数民族和多数民族患者之间的医疗服务差异。然而，目前尚不清楚为什么患有情绪障碍的非洲裔美国人比白人更容易被误诊为精神分裂症。以前的研究者认为，精神分裂症的误诊似乎是因为临床医生未能从患有情绪障碍的非裔美国人身上引出情感症状。此外，当情绪和精神病症状都被确定时，临床医生似乎最大限度地减少了非裔美国人的情感症状。这些发现表明，患有严重情绪障碍的非洲裔美国人比白人更容易被误诊为精神分裂症，因为临床医生过度强调精神病症状，而牺牲了前者的情绪症状。与这一假设相一致的是，非裔美国人更有可能接受过量的抗精神病药物。以前的研究通常只对比非洲裔美国人和白色患者，因此尚不清楚这种误诊问题是非洲裔美国人独有的，还是也发生在其他美国少数民族中。虽然一些研究报告说，情绪障碍也经常被误诊为精神分裂症的拉丁美洲人，其他工作不同意。由于在拉丁美洲人中对这些问题的研究很少，因此很难确定该患者群体的诊断，治疗和种族之间的关联。考虑到这些因素，我们提出了一个大型的，区域多样性，六个网站的合作R01研究，以检查种族对临床诊断和治疗分配的影响，在非洲裔美国人，拉丁美洲人和白色患者的情绪障碍。主要目的是检验一个假设，即临床医生过分强调精神病性症状，而牺牲了非裔美国人的情感症状，导致相对于其他种族群体精神分裂症的临床诊断过多。第二个目的是检验这一假设，即过度强调精神病症状也有助于增加抗精神病药物的使用在非洲裔美国人。最后的目标是确定拉丁美洲人是否有风险在诊断评估和治疗分配类似的问题。
