Print or share the information sheet during a counselling session, GP appointment, mental health lesson or at home to help explain why depression can develop through a mix of biological and psychological factors.
What causes depression can be difficult to explain because low mood often develops from a combination of biology, stress, loss and unhelpful thinking patterns. This printable information sheet offers a clear, one-page overview for adults, older teenagers, carers, students and professionals who need a straightforward way to discuss depressive illness without suggesting there is always one single cause.
It outlines biological factors such as genetic vulnerability, hormones, brain chemicals and neurotransmitters, alongside psychological and life factors such as negative thoughts, bereavement, failure, pressure and stressful events. The wording is designed to support gentle psychoeducation, helping people see how different influences may interact over time and why experiences of depression can vary from person to person.
- Use it in counselling, CBT, wellbeing check-ins or mental health lessons to open a calm conversation about possible triggers and maintaining factors.
- Share it with clients, pupils or family members as a take-home handout after discussing symptoms, support options or next steps.
- Print it for folders, classroom packs, staff reference materials or home learning activities where a concise depression guide is useful.
The sheet can be viewed on screen, downloaded or printed for practical use. It is best used alongside a supportive conversation, giving the reader a simple starting point for understanding depression and noticing which factors may be relevant to their own situation.
