the World Health Organization (WHO) does not consider introversion to be a mental disorder. Introversion is a personality trait characterized by a preference for solitude and a reduced need for social interaction. It is considered a normal variation of human personality and behavior.
The WHO's classification system for mental disorders is known as the International Classification of Diseases (ICD). The most recent version at that time was the ICD-10, and it did not include introversion as a mental disorder. Instead, mental disorders are typically defined based on specific criteria related to symptoms, impairments, and distress that significantly affect a person's functioning and well-being.
The distinction between "normal" and "abnormal" behaviors or traits in the context of mental health is often based on the concept of psychopathology. Psychopathology refers to the study of mental disorders and abnormal behaviors. Mental health professionals and organizations like the WHO assess whether certain traits or behaviors cause significant distress or impair a person's ability to function effectively in their daily life. If a trait or behavior significantly deviates from societal norms and causes impairment, distress, or dysfunction, it may be considered "abnormal" in the context of mental health.
However, it is crucial to emphasize that labeling traits as "normal" or "abnormal" is a complex and value-laden process influenced by cultural, social, and individual factors. It is important to avoid stigmatizing individuals based on personality traits or introversion, as long as it does not lead to significant distress or impairment in their functioning. The understanding and recognition of introversion as a normal and valid aspect of human personality have been increasing in recent years, promoting a more inclusive perspective on mental health.
