If you notice any behavioural changes that last for more than two weeks in family members or friends, then it is worth asking if the person may be depressed.

Common behaviour associated with depression includes:

• moodiness that is out of character
• increased irritability and frustration
• finding it hard to take minor personal criticisms
• spending less time with friends and family
• loss of interest in food, sex, exercise or other pleasurable activities
• being awake throughout the night
• increased alcohol and drug use
• staying home from work or school
• increased physical health complaints like fatigue or pain
• being reckless or taking unnecessary risks (e.g. driving fast or dangerously)
• slowing down of thoughts and actions.

Checklists to Identify Depression

Below are links to some simple checklists that are quick, easy and confidential. These questions are designed to help you reflect on your situation or that of someone close to you. They will not provide a diagnosis - for that you need to see a professional. However, they will tell you if you have symptoms that are common in people with depression. If you think that you or someone you know has depression, please consult a doctor.
