Am I Depressed? The NHS Depression Test

It's not uncommon to experience periods of sadness As we navigate through life. However, when these emotions persist and begin to interfere with daily functioning, it may be a sign of depression.

There are many self-assessment depression tests available online. These must be used cautiously. They should never be used to self-diagnose depression.

The NHS depression test is one of the more reputable assessment tools for identifying depressive symptoms. This test can alert someone to a need for further assessment from a qualified health professional.

Depression is a common mental health disorder that affects millions of people worldwide. The diagnostic criteria for depression include:

  • Persistent sad or irritable mood

  • Loss of interest or pleasure in activities

  • Significant weight loss or gain

  • Insomnia or hypersomnia (excessive sleeping)

  • Physical agitation/restlessness or slow/effortful physical movements (i.e., feeling 'slowed down')

  • Fatigue or loss of energy

  • Feelings of worthlessness or guilt

  • Diminished ability to think or concentrate

  • Recurrent thoughts of death or suicide.

The NHS depression test is also referred to as the PHQ-9. It is a self-assessment questionnaire. This questionnaire helps to determine the severity of depressive symptoms. It consists of nine questions that cover common depression symptoms.

Only a qualified mental health professional should assess and diagnose mental health conditions such as depression. A questionnaire should never be used in isolation to assess a person's difficulties.

Seek help from a qualified health professional or service if you or anyone else is in physical danger. If necessary, call the emergency services in your local area to obtain help.
