Which personality disorder is characterized by extreme dependence on others for advice and support?

Dependent Personality Disorder is characterized by a pervasive and excessive need to be taken care of, leading to submissive and clinging behaviors. Individuals with this disorder often rely heavily on others to make decisions for them and seek advice and support to an extent that can hinder their ability to function independently. This dependency can result in difficulty asserting themselves and a fear of separation or abandonment, making them particularly vulnerable in relationships.

This disorder contrasts with Borderline Personality Disorder, which is primarily characterized by unstable interpersonal relationships, self-image issues, and emotional instability. Narcissistic Personality Disorder, on the other hand, is characterized by a grandiose sense of self-importance and a lack of empathy for others, with a need for admiration from others rather than dependence on them. Avoidant Personality Disorder involves extreme shyness, feelings of inadequacy, and hypersensitivity to negative evaluation, but it does not express dependency in the same overt way as Dependent Personality Disorder. Thus, the core feature of extreme dependence in relationships is most accurately represented by Dependent Personality Disorder.
