Final answer:
The desire for admiration is commonly the underlying need associated with delusions of grandeur. These psychological motives can be explored in group therapy where individuals can address the needs for achievement and affiliation in a supportive environment. The correct option is A.
Step-by-step explanation:
The treatment for mania, particularly when considering the underlying need with delusions of grandeur, involves addressing the psychological motives behind such delusions. These grandiose delusions often stem from a deep-seated psychological need, and among the options provided, the desire for admiration is a common motivating factor.
While low self-esteem and a fear of failure may also be contributing factors, delusions of grandeur are typically characterized by an excessive desire for admiration and recognition.
In the context of various theories of motivation, like Maslow's Hierarchy of Needs or Bandura's concept of self-efficacy, it's evident that delusions of grandeur could be a way for individuals to psychologically cope with or compensate for feelings of inadequacy or a lack of affirmation in their lives.
The need for achievement, driven by the ambition domain, or the need for affiliation and intimacy can be fundamentally related to the formation of such grandiose delusions. In therapy, such as group therapy, these needs can be addressed, and individuals can find support in a safe and structured environment.
