Avoidant Personality Disorder

Excerpt

Avoidant personality disorder (AVPD) is characterized by a persistent pattern of social anxiety, heightened sensitivity to rejection, and pervasive feelings of inadequacy, coupled with a deep-rooted longing for meaningful connections with others. Swiss psychiatrist Eugen Bleuler first described an avoidant personality type in his 1911 work Dementia Praecox: Or the Group of Schizophrenias. German psychiatrist Ernst Kretschmer clarified the distinction between schizoid personality types and avoidant personality types in 1921. In 1980, the Diagnostic and Statistical Manual of Mental Disorders (DSM), 3rd edition, formally included avoidant personality disorder. Historically, there has been some controversy regarding AVPD and social anxiety disorder similarities.

The DSM-5-TR divides personality disorders into Cluster A, Cluster B, and Cluster C. Each cluster encompasses a distinct set of personality disorders with commonalities regarding symptoms, behaviors, and underlying psychological patterns.

Cluster A refers to personality disorders with odd or eccentric characteristics. These include paranoid personality disorder, schizoid personality disorder, and schizotypal personality disorder. Individuals within this cluster often exhibit social withdrawal, peculiar or paranoid beliefs, and difficulties forming close relationships.

Cluster B comprises personality disorders with dramatic, emotional, or erratic behaviors. This cluster includes antisocial personality disorder, borderline personality disorder, histrionic personality disorder, and narcissistic personality disorder. Individuals within this cluster often display impulsive actions, emotional instability, and challenges in maintaining stable relationships.

Cluster C involves personality disorders with anxious and fearful characteristics. These include avoidant personality disorder, dependent personality disorder, and obsessive-compulsive personality disorder. Individuals within this cluster tend to experience significant anxiety, fear of abandonment, and an excessive need for control or perfectionism.

Despite the historical context of using the "cluster" system, there are limitations when approaching personality disorders in this manner, and it is not consistently validated in the literature.
