What Happens During a Depression Evaluation?

Depression is one of the most common mental health conditions, but many people hesitate to seek help because they are unsure what the evaluation process involves. If you are considering scheduling a psychiatry appointment or speaking with an online psychiatrist, understanding how depression is evaluated can make the experience feel much less intimidating.

A depression evaluation is a structured assessment performed by a psychiatric provider to understand symptoms, determine whether they meet criteria for a depressive disorder, and identify safe treatment options. Instead of focusing on just one symptom, the evaluation looks at a person’s overall mental health, including mood, sleep, medical history, medications, and daily functioning. The goal is to understand what someone is experiencing and determine whether depression treatment or further medical evaluation may be helpful.

Depression evaluations are designed to be collaborative conversations rather than tests someone can “pass” or “fail.” A psychiatric provider gathers information about symptoms, how long they have been present, and how they affect everyday life. This helps determine whether symptoms represent temporary stress or a condition that may benefit from professional care.

Understanding the Core Symptoms of Depression

A central part of a depression evaluation involves reviewing the symptoms associated with major depressive disorder. Clinical diagnostic guidelines describe nine key symptoms used to identify depression. 

These include:

• Persistent depressed mood
• Loss of interest or pleasure in activities (often called anhedonia)
• Changes in appetite or weight
• Sleep disturbances
• Psychomotor agitation or slowing
• Fatigue
• Feelings of worthlessness or excessive guilt
• Difficulty concentrating
• Thoughts of death or suicide. [2]

For a diagnosis of major depression, at least five of these symptoms must occur most of the day, nearly every day, for at least two weeks. At least one of the symptoms must be either depressed mood or loss of interest in activities. [2]

During an evaluation, a psychiatric provider will ask detailed questions about these symptoms to understand their severity and impact. For example, they may ask when symptoms began, whether they occur every day, and how they affect work, relationships, or daily responsibilities. This conversation helps determine whether symptoms meet criteria for depression and whether treatment may help.

Screening Tools Used During an Evaluation

Many depression evaluations include standardized screening questionnaires. One of the most widely used tools is the Patient Health Questionnaire-9 (PHQ-9).

The PHQ-9 asks patients to rate how often they have experienced common depressive symptoms during the past two weeks. The total score provides a quick estimate of symptom severity and can help track changes over time.

Research shows that the PHQ-9 is highly effective at identifying major depression. A score of 10 or greater has about 85 percent sensitivity and specificity for detecting the condition. [1] While this type of screening tool is useful, it is only one part of the evaluation. A psychiatric provider also relies on conversation, clinical judgment, and medical history to fully understand a patient’s symptoms.

Reviewing Safety and Psychiatric History

Safety is an important part of every depression evaluation. Psychiatric providers routinely ask about suicidal thoughts, past suicide attempts, or thoughts about harming others. These questions may feel uncomfortable, but they are essential for identifying safety risks and ensuring patients receive appropriate support. [3]

The evaluation also includes a psychiatric history. Patients may be asked about previous mental health diagnoses, past treatment experiences, and any medications they have taken for depression or anxiety. Understanding what has or has not helped in the past can guide treatment planning.

Family history can also be relevant. Depression and other mood disorders sometimes run in families, and learning about family experiences with mental illness can help provide additional clinical context.

Another important part of the psychiatric history is screening for bipolar disorder. Some individuals initially seek care for depressive symptoms but also have a history of periods with unusually high energy, reduced need for sleep, racing thoughts, or impulsive behavior. These symptoms can suggest bipolar disorder rather than major depression, which requires a different treatment approach. [5]

Looking at Medical Causes of Depression

Depressive symptoms are not always caused by a primary mental health disorder. Certain medical conditions can produce symptoms that look very similar to depression. Because of this, psychiatric providers often recommend basic laboratory testing as part of the evaluation.

Common tests may include a complete blood count, metabolic panel, thyroid-stimulating hormone level, and vitamin B12 or folate testing. These tests help identify potential medical contributors to depressive symptoms. [6]

Several medical conditions can mimic depression. Hypothyroidism, for example, can cause fatigue, low mood, and slowed thinking. Anemia may lead to low energy and poor concentration. Certain neurological disorders, infections, and vitamin deficiencies can also affect mood and cognitive functioning. [6]

Identifying medical contributors is important because treating the underlying condition may improve depressive symptoms without the need for psychiatric medications.

Reviewing Medications and Substance Use

Another important part of the evaluation involves reviewing medications and substances that may affect mood. Some prescription medications are associated with depressive symptoms in certain individuals. Examples include beta-blockers, glucocorticoids, hormones, statins, opioids, and some antibiotics. [6]

A psychiatric provider will usually review all prescription medications, over-the-counter drugs, and supplements a patient is taking. Alcohol use and recreational drug use are also discussed, since these substances can influence mood or create withdrawal symptoms that resemble depression.

Understanding these factors helps ensure that treatment plans address the root causes of symptoms whenever possible.

Assessing Daily Functioning

Depression affects more than mood. It often interferes with everyday life, including work performance, social relationships, and daily routines.

During an evaluation, a psychiatric provider may ask about productivity, motivation, sleep patterns, and energy levels. Patients may describe difficulty focusing at work, losing interest in hobbies, or withdrawing from social activities.

These discussions help determine the level of functional impairment caused by symptoms. In older adults, providers may also perform cognitive screening because depression can affect memory and concentration in this population. [4]

What a Telepsychiatry Evaluation Looks Like

Today, many depression evaluations take place through telepsychiatry, allowing patients to connect with a psychiatric provider through secure video visits. Virtual care has become a common way to access mental health services, particularly for individuals who want flexible scheduling or prefer speaking with an online psychiatrist from home.

A typical telepsychiatry evaluation includes discussion of symptoms, review of medical and psychiatric history, screening questionnaires such as the PHQ-9, and a safety assessment. The visit may also include discussion of treatment options and next steps.

Early Evaluation

Everyone experiences stress, sadness, or periods of low energy at times. However, certain symptoms may indicate that it would be helpful to speak with a psychiatric provider.

Depression is highly treatable, and many people improve with the right care. Seeking an evaluation early can help identify symptoms and connect individuals with appropriate depression treatment and support.
