The manipulative person can not trust himself, he could not trust other people as well the manipulator tries to control himself by controlling other because he can't control himself. The most common manipulative behaviors include: intimidates, deceive, self- harm, demands, flatters, ingratiation and so on. The worst part of such behavior is that it will split the health professionals in some way. It also causes conflicts between nursing staff and disturbs the emotional status of them. To avoid these situations, all nursing staff should help patients with consistent attitude. In addition, nurses should master behavior of manipulators to reduce the chance of being manipulated. Helping patients to solve their problems may help build up the sense of trust and security and promote self-control. They will beable to increase recognition of behaviors, mature interpersonal relationship and gain self control.

操控者不会信任自己，更不能信任他人，他无法控制自己，所以由控制他人来控制自己，他们最常表现的操控行为，包括：威胁、欺骗、自我伤害、要求特权、谄媚、迎合他人等，比较严重的是他们会分化整个医疗团队的成员，造成成员之间的冲突及情绪上的困扰，为了避免这些状况产生，所有的成员应该要达成共识，用一致性的态度来帮助病人；另外，护理人员要熟知操控者的行为表现，减少被操控的机会，同时灵活运用问题解决方法，来协助病人对他人产生信任感、安全感及增加对自己的控制感，以达到增加行为的认知，学会成熟人际关系，达到自我控制的目的等预期结果。
