Step-by-step explanation:
People with Paranoid Personality Disorder deeply distrust other people and are suspicious of the motives of others. This condition is characterized by a long-standing pattern of pervasive distrust and suspiciousness of others. A person with paranoid personality disorder will almost always believe that other people's motives are suspect or even malevolent.
Individuals with this disorder are often cold and distant in their relationships and might become controlling and jealous. They may not be able to recognize their own negative feelings towards others and often blame others for personal failures (Schizoid Personality Disorder, Avoidant Personality Disorder, and Dependent Personality Disorder have different primary features).
Secure Attachment Style is the one where the child uses the parent as a base from which to explore their world. Children with secure attachment feel protected by their caregivers, and they know that they can depend on them to return after brief departures.
