Final Answer:
Alice most likely suffers from Obsessive-Compulsive Disorder (OCD).
Step-by-step explanation:
Obsessive-Compulsive Disorder (OCD) is characterized by persistent, intrusive thoughts (obsessions) that lead to repetitive behaviors or mental acts (compulsions). In Alice's case, her irrational fear of germs (obsession) compels her to engage in the repetitive behavior of washing her hands excessively (compulsion). The key features here are the irrationality of the fear, the inability to control the behavior, and the significant distress it causes, which align with the diagnostic criteria for OCD.
The compulsive handwashing in an attempt to alleviate anxiety is a classic manifestation of OCD. The repetitive nature of her behavior and its interference with her daily life suggest a marked impairment, as individuals with OCD often find their rituals time-consuming and distressing. The connection between the compulsive behavior and anxiety reduction is another hallmark of OCD. This disorder typically emerges in early adulthood, and its chronic nature can significantly impact an individual's overall quality of life.
It's crucial for Alice to seek professional help, as cognitive-behavioral therapy (CBT) and, in some cases, medication can be effective in managing the symptoms of OCD. Early intervention and appropriate treatment can greatly improve Alice's ability to cope with her obsessive thoughts and compulsive behaviors, allowing her to lead a more fulfilling life.
