there isn't a specific psychological definition for a "doll collector" in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) or other standard psychological references. Being a doll collector, in itself, is not considered a mental disorder or psychological condition.
"Doll collector" is a term used to describe individuals who have a hobby or interest in collecting dolls. Collecting items, including dolls, can be a normal and enjoyable hobby for many people. People may collect dolls for various reasons, such as aesthetic appreciation, historical interest, sentimental value, or the thrill of the hunt for rare items.
Psychologically, collecting objects can be seen as a form of hobby, interest, or passion that provides individuals with enjoyment, relaxation, and a sense of fulfillment. It can also serve as a means of self-expression or a way to connect with a specific culture or historical period.
However, if doll collecting or any other type of collecting becomes excessive, interferes with daily functioning, causes distress, or negatively impacts an individual's well-being, it could be a symptom of a more significant psychological issue. For instance, hoarding disorder is a recognized psychological condition characterized by excessive collecting and difficulty discarding possessions, leading to clutter and significant distress or impairment in daily life.
It's crucial to remember that hobbies, including collecting, are diverse and can vary greatly from person to person. If you or someone you know is concerned about collecting behavior or any other mental health-related issue, it's advisable to consult a mental health professional for a comprehensive evaluation and appropriate guidance. They can help determine whether the behavior is within the range of a healthy hobby or if it might be indicative of an underlying psychological concern.
