Core Belief Worksheet

When to use the Core Belief Worksheet

The Core Belief Worksheet is an interactive cognitive behavioural therapy (CBT) worksheet, most often used in CBT for depression and low mood.

It is designed to be used within therapy rather than as a standalone self-help tool: a therapist introduces it, works through it collaboratively, and helps make sense of what it surfaces. You can preview the full worksheet above, then assign it digitally for clients to complete between sessions on any device — or download it as a print-ready PDF.

How it works

Most people work through it in around 15 minutes. It moves through three short steps:

1. The Core Belief
2. Examining the Evidence
3. More Balanced Belief

Completed on the Formulate platform, your client's answers are saved automatically and shared straight back to you, so you can review them before the next session rather than waiting for a paper copy to come back.

The CBT approach behind it

In common with other CBT methods, the Core Belief Worksheet works by noticing and re-evaluating unhelpful automatic thoughts (cognitive restructuring). The aim is not positive thinking but a clearer, shared understanding of what keeps a difficulty going — and practical, testable ways to change it.

Because it is a CBT tool it stays focused on the here-and-now links between thoughts, feelings, the body and behaviour, and it works best as one part of a wider course of therapy rather than as advice or a diagnosis.
