缺乏研究探讨个人层面和系统性的种族主义如何导致美国黑人偏执狂的诊断和症状率升高。本研究采用项目反应理论的方法，调查了388名黑人和450名白色参与者的分裂型人格问卷（SPQ）中的项目和子量表水平功能。非精神病对照，患有精神分裂症、情感性精神障碍或典型人格障碍的个体）。据预测，（1）黑人参与者在SPQ的可疑和偏执意念子量表上的得分将显著高于白人，同时控制总SPQ严重程度和相关人口统计学，以及（2）黑人参与者将在较低的潜在严重程度水平（即，总SPQ评分）与白人相比。广义线性模型显示，黑人参与者在抽样偏执狂的子量表上获得了更高的分数（例如，怀疑和偏执意念），而白色参与者在混乱/阳性精神病学子量表（例如，古怪或古怪的行为）。IRT分析表明，黑人个体也赞同在较低的潜在严重程度水平的可疑和偏执意念分量表中的项目，导致膨胀的分量表分数相比，他们的白色同行。结果表明，突出的种族影响自我报告的偏执狂评估的SPQ。这项研究提供了基础数据，以解析什么可能是偏执狂与临床风险指标在美国黑人的规范背书。妄想症的研究和评估的影响和建议进行了讨论。
There is a dearth of research examining how individual-level and systemic racism may lead to elevated diagnostic and symptom rates of paranoia in Black Americans. The present study employed item response theory methods to investigate item- and subscale-level functioning in the Schizotypal Personality Questionnaire (SPQ) in 388 Black and 450 White participants across the schizophrenia-spectrum (i.e., non-psychiatric controls, individuals with schizophrenia, schizoaffective disorder, or schizotypal personality disorder). It was predicted that (1) Black participants would score significantly higher than Whites on the Suspiciousness and Paranoid Ideation subscale of the SPQ, while controlling for total SPQ severity and relevant demographics and (2) Black participants would endorse these subscale items at a lower latent severity level (i.e., total SPQ score) compared to Whites. Generalized linear modeling showed that Black participants endorsed higher scores on subscales sampling paranoia (e.g., Suspiciousness and Paranoid Ideation), while White participants endorsed higher rates within disorganized/positive symptomatology subscales (e.g., Odd or Eccentric Behavior). IRT analyses showed that Black individuals also endorse items within the Suspiciousness and Paranoid Ideation subscale at lower latent severity levels, leading to inflated subscale scores when compared to their White counterparts. Results indicate prominent race effects on self-reported paranoia as assessed by the SPQ. This study provides foundational data to parse what could be normative endorsements of paranoia versus indicators of clinical risk in Black Americans. Implications and recommendations for paranoia research and assessment are discussed.
