Abstract

This Doctor of Nursing Practice staff education project aimed to improve staff knowledge and enhance the consistency in administering and interpreting the Patient Health Questionnaire-9 (PHQ-9) within a mental health clinical setting. The practice problem was significant because variability in PHQ-9 use resulted in unreliable depression screening data, potentially leading to missed detection of depression or suicidal ideation, which undermines patient safety and quality of care. The guiding practice-focused question was: Among healthcare staff administering the PHQ-9, what effect does an educational program have on their knowledge related to the administration, documentation, and interpretation of depression screening? The purpose of the project was to implement an evidence-based education program to enhance staff knowledge and standardize depression screening practices, thereby improving reliability of depression detection and subsequent interventions. Analytical strategies included administering pretests and posttests to measure knowledge gains, along with a program evaluation survey to assess participants’ confidence and intent to change practice. Findings indicated that participants demonstrated increased knowledge and confidence, reported satisfaction with the program, and expressed clear intent to apply best practices. Recommendations include expanding the education program across all staff, integrating PHQ-9 reminders into the electronic health record, and providing mentorship in suicide risk management. Implications for nursing practice include equipping clinicians to provide consistent, evidence-based care. Broader social change impacts include promoting equity, reducing untreated depression, and advancing diversity and inclusion in mental health outcomes.
