Excessive acquisition refers to the compulsive need to obtain and keep items, often resulting in the accumulation of possessions that interfere with daily functioning and living spaces. This behavior is commonly seen in specific disorders where individuals struggle to manage their belongings, leading to distress and impairment in social, occupational, or other areas of functioning. Excessive acquisition is characterized by a lack of insight into the negative consequences of hoarding behaviors and is often tied to underlying psychological issues related to self-image and emotional regulation.
