PHQ-9 GAD-7 Depression and Anxiety Screener
The PHQ-9 and GAD-7 are self-administered questionnaires designed to screen for common mental health conditions. These tools provide a quantitative measure of symptom severity, aiding healthcare professionals in initial assessments. They are not diagnostic instruments but serve as valuable indicators for further clinical discussion and evaluation.
The PHQ-9 (Patient Health Questionnaire-9) assesses depression severity based on nine criteria over the past two weeks. The GAD-7 (Generalized Anxiety Disorder 7-item scale) evaluates anxiety severity using seven criteria over the same period. Both are widely used screening tools in primary care to identify potential mental health conditions and guide further clinical evaluation.
A Depression Anxiety Screener is a tool that uses standardized questionnaires, such as the PHQ-9 and GAD-7, to evaluate the presence and severity of depressive and anxiety symptoms
The PHQ-9 and GAD-7 are self-administered questionnaires designed to screen for common mental health conditions. These tools provide a quantitative measure of symptom severity, aiding healthcare professionals in initial assessments. They are not diagnostic instruments but serve as valuable indicators for further clinical discussion and evaluation.
Variables: Item scores range from 0 (not at all) to 3 (nearly every day). A score of 0 indicates no symptoms. A score of 1 indicates several days. A score of 2 indicates more than half the days. A score of 3 indicates nearly every day.
Worked Example: A user scores 2, 1, 0, 3, 2, 1, 0, 2, 1 on the nine PHQ-9 items, then their PHQ-9 total score is 12. A user scores 1, 2, 0, 1, 2, 0, 1 on the seven GAD-7 items, then their GAD-7 total score is 7.
This screener utilizes the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Both instruments are evidence-based and widely validated screening tools recognized by organizations such as the American Psychiatric Association and the World Health Organization for assessing symptom severity.

Clinical Psychology Methodology - How We Calculate Mental Health Screening Results
Our Depression Anxiety Screener uses clinically validated instruments and APA/NICE guidelines to provide accurate mental health screening. Here's the complete clinical methodology:
PHQ-9 (Patient Health Questionnaire-9)
Gold-standard depression screening instrument:
Scoring: 0 = Not at all, 1 = Several days, 2 = More than half days, 3 = Nearly every day
Clinical Cutoffs: 0-4 None, 5-9 Mild, 10-14 Moderate, 15-19 Moderately Severe, 20-27 Severe
Validated against structured clinical interviews with 88% sensitivity/specificity.
GAD-7 (Generalized Anxiety Disorder-7)
Gold-standard anxiety screening instrument:
Scoring: Same 0-3 scale as PHQ-9
Clinical Cutoffs: 0-4 Minimal, 5-9 Mild, 10-14 Moderate, 15-21 Severe
Sensitivity 89%, Specificity 82% for GAD diagnosis
Also screens for panic, social anxiety, PTSD symptoms.
Functional Impairment Assessment
Item 10 of PHQ-9 assesses impact on daily life:
0 = Not difficult at all
1 = Somewhat difficult
2 = Very difficult
3 = Extremely difficult
Even with low symptom scores, high impairment warrants attention
Critical for determining need for intervention.
Suicide Risk Screening
PHQ-9 item 9 specifically assesses suicidal ideation:
Any positive response (1, 2, or 3) triggers enhanced safety assessment
Score of 2 or 3 = Immediate crisis resource provision
Clinical protocol: Positive response requires safety assessment
Standard of care in depression screening.
Clinical Recommendation Algorithms
Evidence-based treatment recommendations:
Mild (5-9): Watchful waiting, self-help resources, consider brief intervention
Moderate (10-14): Professional evaluation, psychotherapy consideration
Severe (15+): Immediate professional evaluation, consider medication + therapy
With suicide risk: Immediate crisis intervention
Based on APA Practice Guidelines and NICE guidelines.
Dual Diagnosis Considerations
Comorbidity patterns and integrated treatment:
Combined Score Interpretation:
β’ Both scores <10: Minimal symptoms
β’ One score β₯10: Primary disorder focus
β’ Both scores β₯10: Integrated treatment approach
β’ Differential treatment planning based on predominant symptoms
Integrated treatment often most effective for comorbid conditions.

Mental Health Screening Frequently Asked Questions
It calculates scores for depression (PHQ-9) and anxiety (GAD-7) based on your reported symptoms. These scores indicate the severity of potential mental health concerns, helping to identify if further evaluation is needed.
It uses the summation method for both the PHQ-9 and GAD-7. Each question is scored from 0 to 3, and these individual scores are added up to produce a total score for each scale.
A PHQ-9 score of 5-9 suggests mild depression, while 10-14 indicates moderate. For GAD-7, 5-9 suggests moderate anxiety. For example, a score of 8 on both scales points to mild-moderate symptoms.
This screener is a preliminary tool, not a diagnostic one. A clinical diagnosis involves a comprehensive evaluation by a mental health professional, considering various factors beyond questionnaire scores. It serves as a starting point for discussion.
A common mistake is self-diagnosing based solely on the scores. These tools are for screening and should always be followed by consultation with a healthcare provider for accurate diagnosis and treatment planning.
Regularly checking in with your mental health, even when feeling well, can help identify early signs of distress. Early intervention often leads to better outcomes and can prevent more severe issues, promoting overall well-being.
