Final answer:
Pete was diagnosed with Dependent Personality Disorder, which involves a pattern of submissive and clinging behavior because of an excessive need to be taken care of, according to the DSM criteria for this condition.
Step-by-step explanation:
Pete was diagnosed with Dependent Personality Disorder based on specific symptoms criteria as outlined by the Diagnostic and Statistical Manual of Mental Disorders (DSM). The symptoms that led to his diagnosis include:
- A pattern of submissive and clinging behavior related to an excessive need to be taken care of.
This is in line with the DSM, which characterizes Dependent Personality Disorder with a pervasive and excessive need to be taken care of, leading to submissive and clinging behavior and fears of separation. Unlike other personality disorders such as Borderline Personality Disorder, which may present with emotional instability, or Narcissistic Personality Disorder, with grandiosity and attention seeking, Dependent Personality Disorder's core issues revolve around the need for reassurance, advice, and support from others.
