Which of the following is a common behavior in clients with avoidant personality disorder?

The presence of an excessive need for approval is a defining characteristic of avoidant personality disorder. Individuals with this disorder often exhibit a heightened sensitivity to criticism or rejection and tend to see themselves as socially inept or unworthy. This perception drives their behavior, leading them to seek reassurance and approval from others to alleviate their fears of inadequacy and to avoid situations where they may face judgment or disapproval.

In contrast to the other choices, which depict behaviors not typically associated with avoidant personality disorder, the need for approval aligns closely with the core symptoms of this condition. Clients often experience social anxiety and loneliness, as their fear of negative evaluation can hinder their ability to engage with others, resulting in avoidance of social situations.
