We evaluated the 5-item Psychosis Screening Questionnaire (PSQ) against a diagnostic gold standard in South Africa. 1885 adults at primary and tertiary health facilities were screened with the PSQ and diagnosed using the Mini International Neuropsychiatric Interview-V. Minor adaptations were required of both instruments to distinguish between psychiatric symptoms and normative cultural beliefs. We assessed internal consistency, criterion validity and sensitivities and specificities for identifying current or lifetime hypomanic or manic episode and/or psychotic disorders. The PSQ only yielded acceptable criterion validity for lifetime hypomanic or manic episode. A positive PSQ screen yielded sensitivities of 74.36%, 55.00%, and 64.68% for lifetime hypomanic or manic episode, psychotic disorder, and any SMD, respectively. Given the overlap between symptoms and normative cultural beliefs, preemptive framing was required to improve the cultural understanding and relevance. With these adaptations, the translated PSQ functioned adequately for hypomanic or manic episode, but not for psychotic disorder.
我们在南非对照诊断金标准对5项精神病筛查问卷（PSQ）进行了评估。对1885名在初级和三级卫生机构的成年人使用PSQ进行筛查，并采用迷你国际神经精神病学访谈-V进行诊断。两种工具都需要进行轻微调整，以区分精神症状和规范性文化信仰。我们评估了内部一致性、标准效度以及识别当前或终生轻躁狂或躁狂发作和/或精神障碍的敏感性和特异性。PSQ仅对终生轻躁狂或躁狂发作产生了可接受的标准效度。PSQ筛查呈阳性时，对终生轻躁狂或躁狂发作、精神障碍和任何严重精神疾病的敏感性分别为74.36%、55.00%和64.68%。鉴于症状与规范性文化信仰之间存在重叠，需要进行预先设定框架以增进文化理解和相关性。经过这些调整后，翻译后的PSQ在轻躁狂或躁狂发作方面功能良好，但在精神障碍方面则不然。
