Primary and secondary gain
（重定向自Primary gain）
Primary gain or secondary gain are used in medicine to describe the significant psychological motivators patients may have in reporting symptoms.
Primary gain produces positive internal motivations. For example, a patient might feel guilty about being unable to perform some task. If he has a medical condition justifying his inability, he might not feel so bad. Primary gain can be a component of any disease, but is most dramatically demonstrated in conversion disorder (a psychiatric disorder in which stressors manifest themselves as physical symptoms without organic causes, such as a person who becomes blindly inactive after seeing a murder). The "gain" may not be particularly evident to an outside observer.
