原发性精神病性障碍的阴性症状

定义

原发性精神病性障碍的阴性症状包括情感受限、迟钝或平淡，失语或言语贫乏，意志缺乏（普遍缺乏动力、缺乏追求有意义目标的动机），社交贫乏（与他人的接触及社交兴趣减少或缺失）以及快感缺失（不能从通常令人愉悦的活动中体验到愉悦）。阴性精神病性症状不应全部归因于抗精神病药物治疗的效果、抑郁障碍、刺激不足的环境，也不是阳性症状（例如被害妄想导致患者因恐惧被伤害而社交隔离）的直接结果。评价应基于过去1周内阴性症状的严重程度。

Negative symptoms in primary psychotic disorders include constricted, blunted, or flat affect, alogia or paucity of speech, avolition (general lack of drive, or lack of motivation to pursue meaningful goals), asociality (reduced or absent engagement with others and interest in social interaction) and anhedonia (inability to experience pleasure from normally pleasurable activities). To be considered negative psychotic symptoms, relevant symptoms should not be entirely attributable to antipsychotic drug treatment, a depressive disorder, or an under-stimulating environment, and should not be a direct consequence of a positive symptom (e.g., persecutory delusions causing a person to become socially isolated due to fear of harm). The rating should be made based on the severity of negative symptoms during the past week.

这一描述可与精神分裂症和其他原发性精神病的诊断一起使用，以表明负性精神病症状是当前临床表现的一个重要组成部分。负性症状包括情感受限、迟钝或平淡、失语或少言、回避（普遍缺乏动力，或缺乏追求有意义目标的动机）、社交不能（与他人接触减少或缺乏以及对社会交往的兴趣）和快感缺失（无法从正常愉悦的活动中体验到快乐）。相关症状不应完全归因于抗精神病药物治疗、抑郁或刺激不足的环境，否则将被视为负性精神病症状。
