This study has demonstrated that among low-income, relatively unacculturated Mexican-American households, a high level of expressed emotion on the part of key relatives significantly increases the risk of relapse for remitted schizophrenics who return home to live with their families after hospital discharge. This cross-cultural replication of earlier research findings in London and southern California suggests that critical, hostile, or emotionally overinvolved attitudes and behaviors may be general major stressors that adversely influence the fragile adaptation of schizophrenic individuals in diverse cultural settings. The finding of a lower prevalence of high levels of expressed emotion among Mexican-American compared to Anglo-American and British households lends support to the hypothesis that intrafamilial behaviors may account for different schizophrenic outcomes in different cultures.
本研究表明，在低收入、相对未被同化的墨西哥裔美国家庭中，主要亲属表现出的高情感表达显著增加了出院后回家与家人同住的缓解期精神分裂症患者复发的风险。这一对伦敦和南加州早期研究结果的跨文化复制表明，批评、敌意或情感过度卷入的态度和行为可能是普遍的主要压力源，会对不同文化背景下精神分裂症患者脆弱的适应产生不利影响。与英裔美国家庭和英国家庭相比，墨西哥裔美国家庭中高情感表达的患病率较低，这一发现支持了以下假设：家庭内部行为可能是不同文化中精神分裂症不同预后的原因。
