The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) list ten standalone personality disorders and based on similar characteristics, each personality disorder is grouped into one of three categories (cluster A, cluster B, and cluster C). The Oxford English Dictionary defines a personality disorder as “a deeply ingrained pattern of behavior of a specified kind that deviates markedly from the norms of generally accepted behavior, typically apparent by the time of adolescence, and causing long-term difficulties in personal relationships or in functioning in society.” To tell if your partner has a personality disorder it is helpful to have a general understanding of the different types.
Cluster A Personality Disorders
Cluster A personality disorders, as defined by the Mayo Clinic are characterized by eccentric, odd thinking and/ or behavior. Cluster A personality disorders include:
- Paranoid personality disorder: characterized by a pervasive distrust of others. Individuals with paranoid personality disorder are highly suspicious of other’s motives and have a consistent, erroneous fear that others intend to inflict harm.
- Schizoid personality disorder: characterized by a lack of interest in social relationships and difficulty displaying emotion (e.g., emotional coldness, apathy, detachment, etc.).
- Schizotypal personality disorder: characterized by a pattern of intense discomfort with close relationships, social anxiety, and distrust of others.
Though each is a separate condition, they all involve symptoms of exhibiting unusual or eccentric behaviors to others, which can lead to interpersonal and/ or social difficulties.
Cluster B Personality Disorders
Cluster B personality disorders, as defined by the Mayo Clinic, are characterized by patterns of overly emotional, unpredictable, dramatic thinking and/ or behaviors. Cluster B personality disorders include:
- Antisocial personality disorder: characterized by a complete disregard for other individuals.
- Borderline personality disorder: characterized by pervasive instability in moods, self-image, and interpersonal relationships.
- Histrionic personality disorder: characterized by constant attention-seeking, seductive, and provocative behaviors.
- Narcissistic personality disorder: characterized by a pattern of grandiosity, an intense need for admiration and a lack of empathy.
Individuals diagnosed with a cluster B personality disorder are typically faced with difficulty regulating emotions and will likely have issues maintaining relationships.
Cluster C Personality Disorders
Cluster C personality disorders, as defined by the Mayo Clinic, are characterized by anxious, fearful thinking or behavior. Cluster C personality disorders include:
- Avoidant personality disorder: characterized by the avoidance of social situations or interactions that involve risk of rejection, criticism, or humiliation.
- Dependent personality disorder: characterized by a pervasive, excessive need to be taken care of, leading to submissiveness and clinging behaviors.
- Obsessive-compulsive personality disorder: characterized by a pervasive preoccupation with orderliness, perfectionism, and control (with no room for flexibility) that ultimately slows or interferes with completing a task.
While is helpful to be on the lookout for warning signs, to conclusively know if your partner has a personality disorder a professional evaluation is required.
