Adults attending general health facilities in Guiné-Bissau were screened for the presence of mental disorder; minimum estimate of definite mentally ill cases was found to be 12%. The proportion correctly identified by general health workers was low: only one of every three patients with a mental disorder was recognised and of every 100 non-cases 12 patients were wrongly diagnosed by the health worker as suffering from psychiatric illness. On the basis of these results health workers are now being taught how to detect mental illness.
在几内亚比绍，对前往普通医疗机构就诊的成年人进行了精神障碍筛查；发现确诊为精神疾病的病例最低估计比例为12%。普通卫生工作者正确识别出的比例较低：每三名患有精神障碍的患者中只有一人被识别出来，而在每100名非病例中，有12名患者被卫生工作者错误地诊断为患有精神疾病。基于这些结果，现在正在教导卫生工作者如何检测精神疾病。
