The topic I have selected for my practice change scholarly project is the implementation of measurement-based care (MBC) using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) screening tools to enhance treatment outcomes for adults with depression and anxiety in an outpatient psychiatric setting. Depression and anxiety are among the most prevalent mental health conditions encountered in outpatient mental health clinics, significantly affecting emotional well-being and daily functioning. Standard clinical assessment often relies on subjective clinical judgment without consistent use of validated tools, which can lead to variability in symptom monitoring and delays in treatment adjustments (Forand et al., 2025; Azhar et al., 2025). Measurement-based care offers a structured approach where clinicians regularly assess symptom severity, document treatment response quantitatively, and use data to guide clinical decision-making.

The population I will research includes adult patients aged 18 years and older who present to outpatient psychiatric services with symptoms of depression and/or anxiety. These patients commonly experience depressive and anxiety disorders, and they benefit from systematic symptom tracking to inform personalized care plans. The possible intervention will be the routine application of PHQ-9 and GAD-7 as standardized screening tools at each clinical visit, combined with clear workflows for follow-up actions based on score changes. These workflows will include documentation in the electronic health record, scheduled follow-up assessments, and timely adjustments to treatment plans such as medication optimization or referral to psychotherapy when clinically indicated. The PHQ-9 and GAD-7 are validated, brief symptom measures that reliably detect changes in depression and anxiety severity, making them ideal for repeated use in outpatient settings (Faro et al., 2025; Siniscalchi et al., 2020).

The present situation of the problem is that many outpatient psychiatric practices lack a consistent measurement framework, relying instead on traditional clinical interviews and subjective impressions that may miss significant symptom fluctuations over time. Inconsistent symptom monitoring can contribute to delayed identification of treatment nonresponse or emerging safety concerns, which undermines overall care quality. Measurement-based care has been demonstrated to improve clinician documentation behaviors and patient outcomes when systematically adopted; for example, implementation of PHQ-9 and GAD-7 as part of MBC was associated with significant improvements in combined symptom scores and enhanced clinician engagement with outcome data (Forand et al., 2025). Moreover, standardized use of these tools facilitates more objective tracking of treatment progress and supports early identification of symptom exacerbation, which can improve timely care adjustments.

The desired outcome of this project is to enhance the consistency of symptom assessment, improve patient outcomes as reflected in reduced PHQ-9 and GAD-7 scores, and increase clinician responsiveness to changes in clinical status. Outcome measures will include changes in depression and anxiety scores across visits, frequency of documented follow-up plans tailored to symptom severity, and evidence of timely treatment modifications. The time planned for the intervention is eight weeks, which allows for integration of the measurement protocol into routine practice, collection of baseline and follow-up data, and preliminary evaluation of symptom trends and treatment responses.

Implementing this evidence-based measurement protocol is expected to enhance clinical care quality by providing systematic symptom data that can guide personalized treatment decisions, improve patient engagement, and ultimately support better mental health outcomes.
