This study examined whether the sociocultural context moderates the relationship between families' expressed emotion (EE) and clinical outcomes in schizophrenia. In a sample of 60 Mexican American caregivers and their ill relatives, we first assessed whether EE and its indices (criticism, emotional overinvolvement [EOI], and warmth) related to relapse. Second, we extended the analysis of EE and its indices to a longitudinal assessment of symptomatology. Last, we tested whether bidimensional acculturation moderated the relationship between EE (and its indices) and both relapse and symptom trajectory over time. Results indicated that EOI was associated with increased relapse and that criticism was associated with increased symptomatology. Additionally, as patients' Mexican enculturation (Spanish language and media involvement) decreased, EE was increasingly related to relapse. For symptomatology, as patients' U.S. acculturation (English language and media involvement) increased, EE was associated with increased symptoms longitudinally. Our results replicate and extend past research on how culture might shape the way family factors relate to the course of schizophrenia.
本研究考察了社会文化背景是否调节了家庭表达情感（EE）与精神分裂症临床结果之间的关系。在 60 名墨西哥裔美国照顾者及其患病亲属的样本中，我们首先评估了 EE 及其指标（批评、情感过度卷入[EOI]和温暖）是否与复发有关。其次，我们将 EE 及其指标的分析扩展到对症状进行纵向评估。最后，我们测试了双维度文化适应是否调节 EE（及其指标）与复发和症状轨迹随时间变化的关系。结果表明，EOI 与复发增加有关，批评与症状增加有关。此外，随着患者的墨西哥文化适应（西班牙语和媒体参与）的降低，EE 与复发的关系越来越密切。对于症状，随着患者的美国文化适应（英语和媒体参与）的增加，EE 与症状的纵向增加有关。我们的研究结果复制和扩展了过去关于文化如何影响家庭因素与精神分裂症病程关系的研究。
