Psychometrician Board Licensure Practice Exam

Ravi's behavior of brushing his teeth excessively—18 times a day with 83 strokes—suggests a pattern that goes beyond typical dental hygiene practices. This level of repetition and frequency can be indicative of obsessive-compulsive disorder (OCD), which is characterized by unwanted, intrusive thoughts (obsessions) that lead to repetitive behaviors (compulsions). In the case of OCD related to hygiene, individuals often feel compelled to engage in specific routines or rituals to alleviate anxiety associated with their fears about cleanliness or dental health.

This behavior does not simply reflect a strict hygiene regimen or a healthy concern for dental health, both of which would typically be more moderate and in accordance with general recommendations from dental professionals. Furthermore, attempting to impress others doesn't directly align with the nature of obsessions and compulsions present in OCD. Instead, Ravi's actions seem to stem from an internal struggle with anxiety, compelling him to brush obsessively to cope with his worries, which aligns most closely with the symptoms of OCD.
