There is some controversy about whether expressed emotion (EE) tends to remain stable or fluctuates in time and there are very few studies on EE evolution and its subscales once a family intervention has been performed. Better knowledge about its behavior in time would have important theoretical and clinical implications.
We have studied changes in EE and its subscales that are produced in a cohort of 37 relatives of schizophrenic patients to whom a familiar intervention orientated to reducing environmental stress was performed. Changes were analyzed according to three cross-sectional moments of evaluation: one moment previous to intervention, another one when it was finished and finally, one at five years of finishing it.
In this work, the EE levels tend to vary in time. These changes are mainly produced in the period when the family intervention is carried out, at the expense of decreasing the levels of emotional overinvolvement. Between the end of therapy and the analysis carried out five years later, levels remain stable. The few changes that take place in this period, if any, are associated to variables of clinical severity and social adjustment.
Family intervention appears as the determining factor for reducing EE levels, whereas productive clinical severity and the patient's social adjustment condition increases in their levels.
关于情感表达（EE）是倾向于保持稳定还是随时间波动存在一些争议，并且在进行家庭干预后，关于EE演变及其分量表的研究非常少。更好地了解其随时间的变化情况将具有重要的理论和临床意义。
我们研究了37名精神分裂症患者亲属组成的队列中EE及其分量表的变化情况，这些亲属接受了旨在减轻环境压力的家庭干预。根据三个横断面评估时刻分析变化：干预前的一个时刻、干预结束时的另一个时刻以及最后干预结束五年后的一个时刻。
在这项研究中，EE水平随时间变化。这些变化主要发生在家庭干预实施期间，以情感过度卷入水平降低为代价。在治疗结束到五年后的分析期间，水平保持稳定。在此期间发生的少量变化（如果有的话）与临床严重程度和社会适应变量相关。
家庭干预似乎是降低EE水平的决定性因素，而临床严重程度和患者社会适应状况的有效水平有所增加。
