这项研究通过阳性和阴性症状量表(PANSS[Schizopr.胡说八道。13(1987)26 1])在诊断为精神分裂症的三个民族样本中。我们假设，在PANSS的阳性症状和一般症状中，种族差异将比阴性和一般症状更明显。在社区精神卫生诊所接受服务的351人的样本来自精神分裂症护理和评估计划(SCAP)圣地亚哥站点的初始阶段，该计划是一项关于精神分裂症治疗过程的纵向自然主义研究。参与者包括88名非洲裔美国人，198名欧洲裔美国人和65名拉美裔美国人。基线PANSS量表得分和个别项目采用多元协方差分析程序，在控制收入、教育程度和年龄的情况下，按种族和生活状况检查症状。在量表得分上没有显著的种族差异。在条目分析水平上，在幻觉行为、猜疑、兴奋和躯体担忧方面发现显著的种族差异。讨论了每种症状行为的种族差异的文化含义，以及从人种学角度对症状表达进行进一步研究的必要性。(C)2002 Elsevier Science B.V.保留所有权利。
This study examined differences in symptom expression as measured by the Positive and Negative Syndrome Scale (PANSS [Schizophr. Bull. 13 (1987) 26 1]) in a tri-ethnic sample of persons diagnosed with schizophrenia. We hypothesized that ethnic differences would be more apparent in Positive Scale symptoms than in Negative and General Scale symptoms of the PANSS. The sample of 351 persons receiving services in community-based mental health clinics came from the initial phase of the San Diego site of the Schizophrenia Care and Assessment Program (SCAP), a longitudinal naturalistic study on the course of schizophrenia treatment. Participants were 88 African-Americans, 198 Euro-Americans, and 65 Latinos. Baseline PANSS scale scores and individual items were analyzed using Multivariate Analysis of Covariance procedures to examine symptoms by ethnic group and living situation while controlling for income, education, and age. There were no significant ethnic differences on the scale scores. At the item level of analysis, significant ethnic group differences were found in Hallucinatory Behavior, Suspiciousness, Excitement, and for Somatic Concerns. The cultural implications for the ethnic differences in each symptom behavior and the need for further research on symptom expression from an ethnographic perspective are discussed.
