Using a quasi-experimental design, changes in the numbers of mental health facilities between 1964 and 1974 were examined for a sample of 50 nonmetropolitan catchment areas that established a Community Mental Health Center (CMHC) before January 1973 and a sample that did not. Compared to non-CMHC areas, CMHC areas had a slightly greater number of general hospital psychiatric units in 1974. Nevertheless, the rate of increase in such units over the 10-year period was not significantly different between the two types of areas. Other findings supported the conclusion that the number of outpatient and day/night facilities continued to increase in areas not participating in the CMHC program, but that the program produced even greater numbers of such facilities in areas that did participate. This growth, though, occurred both through introducing additional facilities and supplanting existing ones.
采用准实验设计，对1964年至1974年间50个非大都市集水区样本的心理健康设施数量变化进行了研究。这些样本包括1973年1月前设立社区心理健康中心（CMHC）的地区和未设立的地区。与非CMHC地区相比，1974年CMHC地区的综合医院精神科病房数量略多。然而，在这10年期间，两类地区此类病房的增长速度并无显著差异。其他研究结果支持了以下结论：未参与CMHC项目的地区，门诊和日间/夜间设施数量持续增加，但该项目在参与地区产生了更多此类设施。不过，这种增长既通过引入额外设施，也通过取代现有设施实现。
