Thirty-four schizophrenic patients in an acute in-patient hospital were compared with 24 in-patients with major affective disorder and 19 non-patient controls on a role-play test of social skills and a test of affect perception. The role-play test consisted of 12 simulated conversations in which the subject was confronted by parents and friends expressing high-EE criticism or non-critical dissatisfaction. Schizophrenic patients lacked assertiveness and social skills in all conditions, but they did not show any differential impairment when presented with high EE. They consistently lied and denied errors rather than responding assertively or apologizing, whether confronted with high-EE or benign criticisms. On the affect perception test, schizophrenic patients consistently underestimated the intensity or negativeness of negative emotions, but they were not deficient in perception of positive emotional displays. The data do not support the hypothesis that schizophrenic patients are poor at dealing with high-EE behaviours, but do indicate that their ability to cope with even mild negative affect is impaired. Possible explanations for this impairment include limited attentional capacity, a neurologically based perceptual deficit, and a self-protective mechanism to reduce or avoid stress.
对34名急性住院的精神分裂症患者、24名患有重度情感障碍的住院患者以及19名非患者对照者进行了社交技能角色扮演测试和情感感知测试。角色扮演测试包括12次模拟对话,在对话中,受试者面对父母和朋友表达的高情感表达(EE)批评或非批评性不满。精神分裂症患者在所有情况下都缺乏自信和社交技能,但在面对高EE时,他们没有表现出任何差异损伤。无论面对高EE还是良性批评,他们总是说谎并否认错误,而不是自信地回应或道歉。在情感感知测试中,精神分裂症患者始终低估负面情绪的强度或消极程度,但他们对积极情绪表现的感知并不缺乏。数据不支持精神分裂症患者在处理高EE行为方面能力较差的假设,但确实表明他们应对即使是轻微负面情绪的能力受损。这种损伤的可能解释包括注意力容量有限、基于神经学的感知缺陷以及减少或避免压力的自我保护机制。
