Although expressed emotion (EE) has been demonstrated to be associated with the course of schizophrenia, the nature of this relationship is unclear. This study proposes that testing for curvilinear relationships can identify the specific nature of the relationships between EE indices and relapse. The utility of curvilinear models was explored through a reanalysis of data from a prior study of EE among Mexican-Americans (Karno et al., 1987). The results suggest that the relationship between the EE index of emotional overinvolvement (EOI) and relapse is curvilinear and that high levels of EOI may exert a toxic effect on course of illness whereas medium levels of EOI may be protective. The relationship between the EE index of warmth and relapse is also curvilinear and high levels of warmth appear to exert a protective effect on the course of illness. The role of culture is explored in explaining the specific manner in which EE relates to relapse among Mexican-Americans.
尽管已证明情感表达(EE)与精神分裂症的病程有关,但这种关系的本质尚不清楚。本研究提出,对曲线关系进行检验可以确定EE指标与复发之间关系的具体性质。通过对先前一项关于墨西哥裔美国人EE的研究(卡尔诺等人,1987年)的数据进行重新分析,探讨了曲线模型的效用。结果表明,情感过度卷入(EOI)的EE指标与复发之间的关系是曲线关系,高水平的EOI可能对疾病病程产生毒性作用,而中等水平的EOI可能具有保护作用。温暖的EE指标与复发之间的关系也是曲线关系,高水平的温暖似乎对疾病病程具有保护作用。本研究探讨了文化在解释EE与墨西哥裔美国人复发之间具体关系方式中的作用。
