How is a personality disorder diagnosed?

Understanding or diagnosing personality disorders is a complex process that involve examining various factors including behavior, emotions, and interpersonal dynamics. Personality disorders are unique compared to other mental health issues as they pose unique challenges due to the complex overlap and combination between their personality, long-standing behavioral patterns, and problematic symptoms.

Within the field of mental health care, Diagnostic and Statistical Manual of Mental Disorders (DSM) is used as a manual used to guide mental health diagnosis. It’s like a universal language for mental health professionals—a standardized set of criteria and descriptions that help identify and diagnose different mental health issues, including personality disorders. This manual provides a shared framework, ensuring that when professionals discuss and diagnose personality disorders, they’re all working from the same page.

In the DSM, Personality disorders are categorized into three main clusters (A, B, C), each covers distinct types. In simple terms, Cluster A includes odd or eccentric disorders, Cluster B for dramatic or erratic disorders, and Cluster C for anxious or fearful disorders.

There are various methods mental health professionals use to observe and evaluate whether or not someone potentially has a personality disorder such as:

  • Clinical Interviews: Mental health professionals initiate the diagnostic process through comprehensive clinical interviews. These conversations dive into personal history, relationships, and behaviors, providing valuable insights into the individual’s mental background and their subjective experience.
  • Psychological Assessments: Various standardized tests and assessments may be employed to evaluate cognitive and emotional functioning. These tools allow a more holistic understanding of the individual’s psychological profile.

When dealing with personality disorders, there are two main aspects to look out for in the person’s thoughts, behaviors, and emotions:

  • Pervasive Patterns: Personality disorders are characterized by enduring and consistent patterns of behaviors, thoughts, and inner experience in the person’s life. Personality disorders are often marked by behaviors and thoughts that persist over a long period of time instead of contained in short-lived sporadic events. These patterns also usually significantly deviate from cultural norms and cause distress or impairment.
  • Specific Criteria for Each Disorder: Each personality disorder has its unique set of criteria. For example, Borderline Personality Disorder involves instability in relationships, distorted self-image, or self-damaging behavior. In contrast, Narcissistic Personality Disorder centers around an inflated sense of self-importance or low empathy.

Accurately diagnosing personality disorders comes with its own set of difficulties. Distinguishing one personality disorder from the other isn’t always straightforward. Additional factors often muddy the waters. For instance, personality disorders are complex because the individual might refuse acknowledging the fact that they have an issue at all due to the nature of personality disorders that are embedded deeply in their personality. The process of identifying and comprehending personality disorders are usually comparatively more difficult than other mental health issues. Below are a few examples why accurate diagnosis can be tricky:

  • Co-occurring Conditions: Personality disorders often coexist with other mental health conditions, making diagnostic process more difficult. For instance, someone grappling with depression might show withdrawn and apathetic tendencies, mirroring characteristics of a schizoid personality disorder. Another example is someone with emotional instability, impulsivity, and unsteady relationships—a potential mix of characteristics present in both borderline personality disorder (BPD) and bipolar disorder. Mental health professionals must carefully discern whether a particular behavior stems from a specific personality disorder or is a manifestation of another mental health issue.
  • Subjectivity and Stigma: The subjectivity inherent in the diagnostic process and the stigma associated with personality disorders also make it difficult to make absolute diagnosis. Unlike physical medical conditions with visible physical symptoms, personality disorders rely on observable patterns and qualitative assessments based on the affected person’s self-report. Unfortunately, it’s easy for affected individuals to be biased when discussing their experiences or behaviors. They may be resistant to acknowledging potential issues due to fear of judgment. Likewise, mental health practitioners, while equipped with extensive training and experience, can unknowingly bring their unique understanding to the diagnostic table. This subjective viewpoint can influence how they interpret behaviors, making each case a unique and personalized process.

While information is readily available, attempting to self-diagnose personality disorders can be misleading and risky. The complexity of these conditions require the expertise of trained professionals who can avoid misinterpretations and misinterpretations. Self-diagnoses may lead to unnecessary distress, misunderstanding, and misidentification of symptoms. Just like other health concerns, when in doubt, it’s best to seek the guidance of a professional for accurate assessments.
