The factors influencing the development of expressed emotion (EE) are still unclear. Understanding the carer and patient appraisals operating during the initial adaptation to psychosis may help to clarify the early ontogenesis of EE.
Fifty patients and key carers were followed-up over 9 months and their appraisals of loss and burden were measured in relation to the evolution of high emotional overinvolvement (EOI) and critical (CC) relationships.
The appraisal of loss was linked to high EOI but not high CC relationships at baseline. Loss reduced by 9-month follow-up in those changing from high EOI to high CC or low EE. Subjective burden of carers was linked to loss but not to EE status. Patients' and relatives' appraisals of loss were strongly correlated, particularly in high EOI relationships. Longer duration of untreated psychosis was associated with high CC.
The results are consistent with Bowlby's attachment theory, where EOI and coercive criticism may be understood as adaptive reactions to perceived loss. Implications for family intervention in first-episode psychosis and the prevention of high EE are discussed.
影响情感表达(EE)发展的因素仍不明确。了解在首次适应精神病过程中照顾者和患者的评估,可能有助于阐明EE的早期发生机制。
对50名患者及其主要照顾者进行了9个月的随访,并根据高情感过度卷入(EOI)和批评(CC)关系的演变,测量了他们对丧失和负担的评估。
在基线时,对丧失的评估与高EOI相关,但与高CC关系无关。在那些从高EOI转变为高CC或低EE的患者中,到9个月随访时丧失感减轻。照顾者的主观负担与丧失有关,但与EE状态无关。患者和亲属对丧失的评估高度相关,尤其是在高EOI关系中。未治疗精神病的持续时间较长与高CC相关。
结果与鲍尔比的依恋理论一致,其中EOI和强制性批评可被理解为对感知到的丧失的适应性反应。讨论了对首发精神病家庭干预及预防高EE的意义。
