费力

The WHO neurosis screening schedule is the best in both sensitivity and specificity of validity, but its practice is time-consuming and laborious, which limits its application. SCL-90 and CMI are imperfect in sensitivity of validity, and they cannot screen out the mental disorder in more than a half of the subjects. In a group test, they can hardly serve as a screening tool. UPI can screen out most of the mental disorder, and its sensitivity of validity reaches 83.1%. Additionally, the UPI questionnaire contains fake-test items, which could retest those who were missed due to untruly or not conscientiously answer the questionnaires. An acceptable way to obtain a true screening test is to give the individuals a propaganda of mental health and explain the questionnaires for 30 minutes before the test, which helps the examinee to understand the procedure and accept the questionnaires, so that the results of the test could be more reliable. In conclusion, UPI is a valuable screening tool to be recommended.

WHO神经症筛选表的灵敏度特异度都是最好的，但其操作费时费力，故适用性受限；以SCL-90和CMI二者的灵敏度很不理想，约一半以上的患者被筛漏，难以用团体测验方式作为筛选工具；UPI的灵敏度达83.1%，绝大多数病患可被发现，量表有测伪项目，可将不真实、不认真填写而遗漏的病患进行重测补救，且测前有30min时间进行心理卫生宣传和介绍防治人员服务内容、联系方法，使存在问题的人主动应询，从而可避免遗漏，是值得推荐的筛选工具。
