PHQ-9 Depression Scale Questionnaire

The PHQ-9 is a measurement tool providers can use to ensure measurement-based treatment to target within Collaborative Care. This concise nine-item health questionnaire can function as a screening tool, aids in diagnosis, and measures treatment response.

Advantages of the PHQ-9

Patient filling out PHQ-9

  • It is shorter than other depression rating scales
  • Multiple administration options (in person by a clinician, by telephone, or self-administered by the patient)
  • Facilitates diagnosis of major depression
  • Assesses symptom severity
  • Well-validated and documented in a variety of populations
  • Directly based on the nine diagnostic criteria for major depressive disorder in the DSM-5
  • Valid for use in adolescents as young as 12 years of age

How to Use the PHQ-9

At the initial visit, the PHQ-9 aids in the diagnosis and identification of potential depressive symptoms. At follow-up visits, it measures treatment response. The Questionnaire can be clinician or self-administered.

Scoring the PHQ-9

The PHQ-9 is a tool to assist clinicians in identifying and diagnosing major depression. It has a maximum score of 27. Elevated scores strongly correlate with a major depression diagnosis. However, it’s essential to remember that not everyone with a high PHQ-9 score will have major depression. Trained clinicians must make the final diagnosis.

Patient Health Questionnaire 2 (PHQ-2)

The Patient Health Questionnaire 2 (PHQ-2) effectively screens large groups for depression. It consists of the first two questions on the PHQ-9. If the patient responds affirmatively to either question on the PHQ-2, the PHQ-9 should be administered. No permission is required to reproduce, translate, display, or distribute the PHQ-2.

PHQ-9 Questionnaire and Translations

The PHQ-9, translations of the measure, and an instruction manual are available at www.phqscreeners.com. No permission is required to reproduce, translate, display, or distribute the PHQ-9.

Protocols for Suicide Prevention

The PHQ-9 asks about suicidal ideation, and clinics should have a plan in place for when a patient scores positive on this question. The Protocols for Suicide Prevention in Primary Care assists clinics in refining existing protocol(s) for responding to patients who present with suicidality or violent behavior.

Introducing the PHQ-9

To increase staff comfort in discussing the PHQ-9 with patients, the AIMS Center provides the Helping Clinic Staff Talk about the PHQ-9 tool. This resource equips clinic staff to administer the PHQ-9 by addressing commonly asked patient questions.

Help Clinic Staff Talk with Patients About the PHQ-9

This tool is designed to help clinic support staff with answers to frequent questions they may hear from patients about the PHQ-9.

It’s best for support staff to have the opportunity to role play and practice before using the PHQ-9 with patients. It can also be helpful for support staff to keep this someplace where they can refer to it, as needed, when they get questions from patients.

Developing Protocols for Suicide Prevention in Primary Care

Introduction

Primary care clinics have a responsibility to provide effective and efficient suicide safe care that is accessible to all patients and staff. Developing a thoughtful and clear protocol and workflow for responding to suicidality in your primary care setting will empower staff to know how to act as well as help keep patients and staff safe.

The resource below contains information about screening and identification, conducting risk assessments, response and follow-up to suicide risk, as well as several additional resources. This information is intended to guide primary care clinics to refine existing protocol(s) for responding to patients presenting with suicidality or violent behavior in a primary care clinic.

Developing Protocols for Suicide Prevention in Primary Care

Primary care clinics have a responsibility to provide effective and efficient suicide safe care that is accessible to all patients and staff. Developing a thoughtful and clear protocol and workflow for responding to suicidality in your primary care setting will empower staff to know how to help keep patients safe. This information is intended to guide primary care clinics to refine existing protocol(s) for responding to patients presenting with suicidality in a primary care clinic.

Principles

All clinic staff are informed and supported

One-page workflows for responding to suicidal ideation should be easily accessible to all staff (not just the behavioral health staff or the clinic manager). These workflows should clearly outline when and how to respond, who to engage, and list internal and external resources. The 988 Suicide and Crisis Lifeline or other relevant emergency/crisis numbers are easily available. And staff are informed on how to contact the crisis response teams if available in your setting.

Collaboratively develop safety plans

A safety plan provides guidance and resources for the patient to reduce their risk of suicidal behavior. This is a collaborative document that includes holistic assessment paired with individualized intervention, as opposed to a safety contract, which is an agreement not to self-harm. There is no evidence that contracting for safety with a patient is effective at reducing suicides. In addition, contracts have no legal meaning and may give a false sense of security to a provider.

Take risk seriously

Primary care clinics should be screening patients to identify those at risk of suicide. Appropriate risk assessment and intervention should be completed for every patient identified with risk of suicide, every time.

Suicide Prevention Protocol Elements

The below sections provide descriptions of the key suicide prevention protocol elements, as follows:

  1. Screening and identification of suicide risk
  2. Asking about and assessing suicide risk level
  3. Responding to suicide risk level
  4. Follow up & next steps in care

1. Screening and identification of patients at risk of suicide

Any patient presenting for mental health or substance use treatment should be screened for thoughts of suicide with a validated screening tool. The PHQ9 question #9 is one example. It reads, “Have you been having thoughts that you would be better off dead or thoughts of hurting yourself in some way?”. When a patient scores positive for suicide risk, further information should be gathered.

2. Ask about and assess suicide risk level to determine next steps

To determine suicide risk level, a trained staff person should administer a validated screening tool like the Columbia-Suicide Severity Rating Scale (C-SSRS), Ask Suicide-Screening Questions (ASQ) and/or the Suicide Assessment Five-Step Evaluation and Triage (Safe-T). Providers should be trained to communicate with patients who are suicidal in a calm, curious, and caring manner. Validated tools when combined with clinical judgement can help determine levels of risk and aid in making clinical decisions about care.

In general, suicide risk level can be grouped into two categories:

Non-Acute Risk           

Imminent risk of completing suicide is not identified; indicates the patient can safely continue treatment in primary care with appropriate intervention.

Acute Risk

Imminent risk of completing suicide is identified; indicates patient should be under safe observation until a crisis response team completes an evaluation or patient is taken to an Emergency Department for potential hospitalization.

Levels of risk can be classified differently depending on the validated tool used. Some tools, like the C-SSRS or SAFE-T assign “high”, “moderate” or “low” values influenced by modifiable risk factors and protective factors. Classifications like these support interventions that are responsive to patient risk level.

3. Responding to suicide risk level

Non-Acute Risk Interventions: If risk is non-acute, the next step is to develop a collaborative safety plan. This is an important clinical component of treating a patient in an outpatient setting. Even when a patient is experiencing passive suicidal ideation, a safety plan should be done because suicide risk is not fixed and can change over time. Safety planning should address risk factors that can be modified, including limiting access to lethal means.

Acute Risk Interventions: If risk is acute, the provider should have a direct conversation about next steps for maintaining the patient’s safety. A clinic staff member should remain with the patient until the patient is evaluated by a crisis response team or in safe transport to an Emergency Department. Clinic staff should be trained on how to coordinate and provide relevant chart notes for the referral. A plan should be in place for appropriate action if a patient refuses care or leaves the clinic against medical advice (AMA). This may include contacting a crisis response team or the police.

4. Follow up & next steps in care

The clinic should have a clear process to follow up with patients who have presented with suicidal risk. This includes clear guidelines on how to regularly track, follow up on and review safety plans with patients. Staff should be trained in where to find completed plans in the EHR.

For patients who receive further evaluation by a crisis response team or Emergency Department, the primary care clinic should have a plan for coordinating care, including who is responsible for documenting and communicating evaluation outcomes and patient care plan with the team.

The clinic should offer support and follow up to staff who may be impacted by a patient treated for suicide risk or who dies by suicide.
