Depression is a debilitating and damaging mental health condition that goes far beyond simply feeling down or sad, and is a physiological change in the body that can persist for months or even years. It can lead to loss of appetite, apathy, sexual disinterest, thoughts of suicide and lead to severe consequences in work, relationships and family life.

Depression is immensely challenging to understand and work with, and varies hugely from person to person. Understanding the complexities underlying the depressed feelings, often from childhood and relational contexts can begin to help bring understand and context to how one is feeling and provide a platform for development and healing.

Assessment for clinical depression is never easy as subjectivity plays a huge part in determining how an individual will respond to questions and assessment. The NHS uses a Patient Health Questionairre in order to ascertain levels of depression and determine appropriate treatment and assess progress. A sample of the form is below:


How often you have felt each of these statements over the last two weeks ?
Little interest or pleasure in doing things
Feeling down, depressed, or hopeless
Trouble falling or staying asleep, or sleeping too much
Feeling tired or having little energy
Poor appetite or overeating
Feeling bad about yourself — or that you are a failure or
have let yourself or your family down
Trouble concentrating on things, such as reading the
newspaper or watching television
Moving or speaking so slowly that other people could have
noticed? Or the opposite — being so fidgety or restless
that you have been moving around a lot more than usual
Thoughts that you would be better off dead or of hurting
yourself in some way
