A 19-year-old man presents to the PMHNP for a psychiatric evaluation with a chief complaint of intrusive thoughts and compulsive behaviors. Of the following, which is considered the gold standard assessment tool for obsessive-compulsive disorder (OCD) severity?
Obsessive-Compulsive Inventory (OCI)
Florida Obsessive-Compulsive Inventory (FOCI)
Yale-Brown Obsessive Compulsive Scale (Y-BOCS)
National Institute of Mental Health-Global Obsessive-Compulsive Scale
The Correct Answer is C
Choice A reason: The OCI is a self-report questionnaire and useful for screening, but it is not considered the gold standard for severity assessment.
Choice B reason: The FOCI is a brief assessment tool, helpful in research or clinical settings, but lacks the comprehensive evaluation of Y-BOCS.
Choice C reason: The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is the gold standard clinician-administered measure for assessing OCD symptom severity and monitoring treatment response.
Choice D reason: The NIMH Global OCD scale is less commonly used and lacks the specificity and validation of Y-BOCS for clinical severity assessment.

Correct Answer is C
Explanation
Choice A reason: This question assesses for sleep disorders or narcolepsy, not trauma history.
Choice B reason: This question evaluates dissociation or depersonalization, which may occur secondary to trauma but is not a direct trauma screening question.
Choice C reason: Asking about the worst event in a person’s life directly elicits a trauma history and can uncover exposure to physical, emotional, or sexual abuse, accidents, or other life-threatening experiences. This question is essential for identifying PTSD risk.
Choice D reason: This question screens for phobias or situational anxiety rather than traumatic experiences.
Correct Answer is D
Explanation
Choice A reason: The Beck Anxiety Inventory is a self-report measure mainly used for screening anxiety in the general population, not specifically in clinical assessment settings requiring clinician-administered evaluation.
Choice B reason: The HADS-A is used for screening anxiety and depression in medically ill patients but does not provide detailed gradation of anxiety severity.
Choice C reason: The State-Trait Anxiety Inventory measures both temporary state anxiety and chronic trait anxiety but is primarily used for research and not preferred for clinical diagnostic assessment.
Choice D reason: The Hamilton Anxiety Rating Scale is the most widely used clinician-rated tool to assess the severity of anxiety symptoms in psychiatric settings. It evaluates both somatic and psychological symptoms of anxiety, allowing for accurate assessment of symptom intensity and treatment response in clinical practice.
