Persistent Depressive Disorder Quality Control & Assurance 2

Question 1

Which validated tool is most commonly used to monitor treatment response and symptom severity over time in patients with Persistent Depressive Disorder?

Accepted Answer

Patient Health Questionnaire-9 (PHQ-9)

Answer

The PHQ-9 is widely used in clinical settings to track depressive symptom severity and treatment response in PDD.

Question 2

A quality assurance audit finds that clinicians are not documenting functional impairment in PDD cases. Why is this a critical gap?

Accepted Answer

DSM-5 requires clinically significant distress or functional impairment as a diagnostic criterion

Answer

DSM-5 requires that PDD symptoms cause clinically significant distress or functional impairment, making its documentation essential for diagnostic validity.

Question 3

What is the minimum symptom duration that must be documented to meet quality standards for a valid PDD diagnosis in adults?

Accepted Answer

2 years

Answer

PDD requires depressed mood for at least 2 years in adults, and failure to document this duration is a quality error.

Question 4

A clinic implements measurement-based care (MBC) for PDD patients. What is the primary quality benefit of this approach?

Accepted Answer

It allows treatment adjustments based on objective, tracked symptom data

Answer

MBC uses standardized assessments at each visit to inform data-driven treatment decisions and improve outcomes in PDD.

Question 5

According to quality standards, how long should a clinician wait before evaluating the adequacy of an antidepressant trial for PDD?

Accepted Answer

4–8 weeks at therapeutic dose

Answer

An adequate antidepressant trial typically requires 4–8 weeks at therapeutic dose before efficacy can be assessed.
