What does a depression score of 14 mean?

A depression score of 14 on a commonly used depression screening tool like the Patient Health Questionnaire-9 (PHQ-9) indicates moderately severe depression. The PHQ-9 is a 9-item self-report questionnaire that screens for the presence and severity of depression symptoms over the past 2 weeks. Each item is scored from 0 (not at all) to 3 (nearly every day), with total scores ranging from 0 to 27. A score of 14 falls within the range of 10-19, which is interpreted as moderately severe depression according to the PHQ-9 scoring interpretation.

PHQ-9 Scoring Interpretation

Here is an overview of the PHQ-9 score interpretations:

PHQ-9 Score Depression Severity
0-4 None
5-9 Mild
10-14 Moderate
15-19 Moderately severe
20-27 Severe

As shown in the table, a PHQ-9 score of 14 falls in the moderately severe range of depression severity. This level of depression is associated with functional impairment and typically requires active treatment with psychotherapy, medications, or both.

Symptoms of Moderately Severe Depression

A person with a depression score of 14 is likely experiencing multiple symptoms of depression most days, with at least several symptoms being present nearly every day. Here are some of the key symptoms that may be present in moderately severe depression:

  • Feeling down, depressed, or hopeless nearly every day
  • Markedly diminished interest or pleasure in activities
  • Significant weight loss or gain when not dieting
  • Insomnia or sleeping too much
  • Agitation or psychomotor retardation noticed by others
  • Fatigue or loss of energy
  • Excessive or inappropriate feelings of guilt or worthlessness
  • Diminished ability to think, concentrate, or make decisions
  • Recurrent thoughts of death, suicidal ideation, or attempt

A person with several of these symptoms is likely struggling to function in their daily life. Work, school, relationships, self-care, and other areas may be significantly impaired by the depression symptoms.

Treatment Implications

A PHQ-9 score of 14 has important implications for treatment. Specifically:

  • Active treatment is recommended, as moderately severe depression is unlikely to resolve on its own.
  • Treatment may include psychotherapy, antidepressant medication, or both.
  • The person should be monitored closely during treatment given the severity of symptoms.
  • Hospitalization may need to be considered if there is a significant suicide risk or inability to care for oneself.
  • Treatment should continue until symptoms have resolved sufficiently, with the goal of achieving remission of the depressive episode.

Some key considerations for treating moderately severe depression include:

Psychotherapy

Types of psychotherapy known to be effective for depression include:

  • Cognitive behavioral therapy (CBT)
  • Interpersonal therapy (IPT)
  • Behavioral activation
  • Problem-solving treatment

Psychotherapy helps people understand their depression and make positive changes in thinking, behavior, and communication to manage symptoms. Ongoing support and skills building help prevent relapse.

Medications

First-line antidepressant medications include:

  • Selective serotonin reuptake inhibitors (SSRIs)
  • Serotonin-norepinephrine reuptake inhibitors (SNRIs)
  • Bupropion
  • Mirtazapine

Medications help correct chemical imbalances implicated in depression. They can take 4-6 weeks to become fully effective. Side effects may occur but often improve with time.

Complementary Approaches

Other approaches that may help when added to psychotherapy and/or medication include:

  • Exercise
  • Stress management
  • Mindfulness meditation
  • Light therapy for seasonal affective disorder
  • Omega-3 fatty acid supplements
  • SAMe supplements

Lifestyle adjustments to regulate sleep, diet, and social engagement can also relieve depressive symptoms.

Monitoring

Given the severity of moderately severe depression, ongoing monitoring is important. Follow-up PHQ-9 scores can track changes in symptom severity. Frequency of contact, such as weekly psychotherapy or medication management sessions, may be needed to ensure safety and treatment adherence.

Functioning Impacts

A depression score of 14 typically equates to moderate-to-severe impairment in functioning and quality of life. Common areas of impairment include:

  • Work – Reduced productivity, increased errors, absenteeism, conflict with co-workers
  • School – Declining grades, difficulty concentrating, skipped classes
  • Relationships – Withdrawal from friends/family, loneliness, marital conflict, neglect of children
  • Self-care – Poor hygiene, irregular meals, weight changes
  • Mood – Persistent sadness, irritability, worthlessness
  • Thoughts – Suicidal ideation, pessimism, self-criticism

Targeted treatment focusing on the person’s impaired areas of functioning is recommended to help restore wellbeing and daily stability.

Criteria for Diagnosis

While the PHQ-9 measures depression symptom severity, a clinical diagnosis of major depressive disorder requires meeting formal diagnostic criteria. These criteria in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) include:

  • Depressed mood and/or loss of interest or pleasure for at least 2 weeks
  • At least 5 of the following additional symptoms:
    • Significant weight loss or gain or appetite changes
    • Insomnia or sleeping too much
    • Agitation or psychomotor retardation
    • Fatigue
    • Excessive guilt or worthlessness
    • Difficulty concentrating or making decisions
    • Suicidal ideation
  • The symptoms cause significant impairment in functioning
  • The symptoms are not attributable to effects of a substance or medical condition

A full clinical interview and assessment is needed to apply these diagnostic criteria. But a PHQ-9 score of 14 suggests many of the criteria are likely met in a moderately severe presentation of major depression.

Duration

Major depressive episodes by definition last at least 2 weeks, but can persist for several months to years if left untreated. On average, an untreated episode may last 4-5 months, but with huge variability. Treatment can help shorten episode duration by helping the person manage and reduce symptoms.

It’s important to continue treatment even after mood starts improving, as full remission may take weeks. Stopping treatment too soon increases relapse risk.

Causes

There are multiple potential causes of moderately severe depression with a PHQ-9 score of 14, including:

  • Biological factors – Genetics, brain chemistry imbalances, hormonal changes
  • Stress – Trauma, loss, chronic stressors
  • Personality – Pessimism, low self-esteem, perfectionism
  • Medical conditions – Chronic illness, pain, medications
  • Substance use – Alcohol, drugs, withdrawal

Often depression arises from a combination of biological vulnerabilities and environmental stressors or triggers. A comprehensive evaluation can help identify relevant factors to address through treatment.

Risk Factors

Factors that increase risk for developing moderately severe depression include:

  • Family history of depression
  • Chronic medical condition
  • Pain syndrome
  • Trauma or prolonged stress
  • Social isolation
  • Rumination and pessimistic thinking style
  • Poor coping skills
  • Low self-esteem
  • Childhood adversity or neglect
  • Substance abuse
  • Unemployment
  • Major life changes

Identifying and modifying relevant risk factors can help prevent severe depressive episodes in the future. For example, building social connections, adopting active coping strategies, and pursuing meaning and purpose can strengthen resilience.

Conclusion

In summary, a depression score of 14 on the PHQ-9 indicates moderately severe major depression. It signifies functional impairment from a cluster of depressive symptoms occurring most days for at least 2 weeks. Active treatment with psychotherapy and/or antidepressant medication is recommended, along with monitoring for suicidal ideation. Restoring functioning in work, school, self-care, relationships, and mood management are treatment goals. With appropriate care matched to the needs of the individual, recovery is very possible.
