多重人格症状（Multiple Personality Disorder）是一种心理疾病，现已更名为分离性身份障碍（Dissociative Identity Disorder，DID）。这种疾病常常表现为一个人拥有两个或更多不同的身份或人格状态，每种人格状态都有其独特的思维、行为和情感模式。
多重人格障碍（Multiple Personality Disorder，MPD）现在更常用的术语是解离性身份障碍（Dissociative Identity Disorder，DID），它是一种严重的心理障碍，个体在意识、记忆、身份和情感等方面经历多个分离的身份状态。以下是一些与多重人格障碍相关的文献：
