Final answer:
Sally's ritualistic and repetitive cleaning behaviors, which she feels compelled to perform multiple times a day, are symptomatic of Obsessive-Compulsive Disorder (OCD).
Step-by-step explanation:
The student's question is attempting to identify the mental health disorder that Sally's cleaning behaviors most closely resemble. Sally is engaged in ritualistic cleaning, especially with an emphasis on ensuring the fringe on her rugs is straight, and she repeats this cycle many times throughout the day.
This behavior is indicative of Obsessive-Compulsive Disorder (OCD). OCD is characterized by the presence of obsessions (intrusive thoughts, impulses, or images) and compulsions (repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession).
The fact that Sally cleans for 3 to 4 hours per day and feels the need to continually straighten the fringe on her rugs suggests that she may be experiencing compulsions aimed at reducing distress associated with obsessive concerns around cleanliness or symmetry.
