What is a characteristic behavior of Cluster A personality disorders?

Cluster A personality disorders are primarily characterized by eccentric or strange behaviors, and this is where suspicious behavior particularly fits in. Individuals with these disorders, which include paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder, often display unusual thought patterns, social awkwardness, and a tendency to be mistrustful or suspicious of others.

The emphasis on eccentricity includes behaviors that can be seen as odd or unconventional, which aligns with the characteristics of individuals within this cluster. For instance, someone with paranoid personality disorder may exhibit pervasive distrust and suspiciousness of others, leading them to interpret benign remarks as threatening.

In contrast, the other options include features that are not typical of Cluster A disorders. Overly dramatic behavior is more associated with Cluster B personality disorders, which center around emotional and erratic traits. Excessive anxiety and worry relate more to anxiety disorders and some features of Cluster C personality disorders, while fear of rejection and abandonment aligns with disorders like borderline personality disorder, which also belongs to Cluster B. Thus, recognizing the unique traits of Cluster A helps distinguish it clearly from other clusters in personality disorders.
