尽管对精神病临床高危状态的认识迅速增长,但绝大多数病例对照研究都依赖于健康志愿者作为参考点来推断精神病的高危状态。研究人员早就认识到,从这种设计产生的结果是有限的显着的解释问题,但很少有人注意到这些问题如何影响不断增长的领域的可持续发展的研究。我们认为,过度依赖于健康对照组的研究威胁的有效性推断有关组的差异,阻碍了进步,了解精神病的发展,并限制了临床进展。我们建议结合使用健康和寻求帮助(即,精神病学)控制是下一代研究的必要步骤。然后,我们评估方法寻求帮助的对照研究,确定可用的研究,使用这种设计,讨论选择在这方面的研究结果,并提供建议的研究。
Despite rapidly growing knowledge of the clinical high-risk (CHR) state for psychosis, the vast majority of case-control studies have relied on healthy volunteers as a reference point for drawing inferences about the CHR construct. Researchers have long recognized that results generated from this design are limited by significant interpretive concerns, yet little attention has been given to how these concerns affect the growing field of CHR research. We argue that overreliance on healthy controls in CHR research threatens the validity of inferences concerning group differences, hinders advances in understanding the development of psychosis, and limits clinical progress. We suggest that the combined use of healthy and help-seeking (i.e., psychiatric) controls is a necessary step for the next generation of CHR research. We then evaluate methods for help-seeking control studies, identify the available CHR studies that have used such designs, discuss select findings in this literature, and offer recommendations for research.
