A study was carried out to compare the sensitivity as well as cost of three different methods of psychiatric case detection. It was found that the simplest method, which involved interviewing about 3% of the adult population, with a questionnaire taking only five minutes to complete, picked up as many adult epileptics and nearly as many psychotics as the inquiry with all the adults in the population using a sophisticated structured interview schedule. A method of medium complexity, in which the short five-minute questionnaire was given to one adult member of each family, detected in addition to all adult epileptics and psychotics, and many juvenile epileptics and mentally retarded. The cost of the simplest method was one-ninth and that of the method of medium complexity, one-fifth of the cost of the most sophisticated method. The method of medium complexity is recommended for use in the rural psychiatry programme of the developing countries.
开展了一项研究，以比较三种不同精神病病例检测方法的敏感性和成本。结果发现，最简单的方法是对约3%的成年人口进行访谈，使用只需五分钟就能完成的问卷，该方法发现的成年癫痫患者数量与使用复杂结构化访谈时间表对全体成年人进行调查时发现的一样多，发现的精神病患者数量也几乎相同。中等复杂程度的方法是向每个家庭的一名成年成员发放简短的五分钟问卷，除了所有成年癫痫患者和精神病患者外，还发现了许多青少年癫痫患者和智力迟钝者。最简单方法的成本是最复杂方法的九分之一，中等复杂程度方法的成本是最复杂方法的五分之一。建议在发展中国家的农村精神病学项目中使用中等复杂程度的方法。
