Our thoughts can fall into habits
Our thoughts feel like simple facts, but they are not always accurate. When we are stressed, low or anxious, our thinking can slip into biased habits that paint a darker or more extreme picture than the situation deserves. These patterns are known as cognitive distortions (sometimes called unhelpful thinking styles). Everyone does this, it is part of being human. Learning to spot these habits is one of the core skills in CBT, because once you notice a thought is just a habit, you no longer have to take it at face value.
Styles that twist the bigger picture
All-or-nothing thinking sees things in black and white, with no middle ground: one slip means I have failed completely. Catastrophising jumps to the worst possible outcome: this headache must be something serious. Overgeneralisation takes one event as a never-ending pattern: I got that wrong, I always mess things up. Magnification and minimisation blows up the bad and shrinks the good: my mistake was huge, but that compliment meant nothing.
Styles that filter what we notice
Mental filter zooms in on one negative detail and ignores everything else: the day was fine, but I cannot stop thinking about that one awkward moment. Disqualifying the positive brushes off good things so they do not count: they only said well done to be nice. Mind-reading assumes we know what others think, usually the worst: she did not reply, she must be annoyed with me. Fortune-telling predicts the future as if it were certain: there is no point trying, it will go wrong.
Styles about ourselves and the rules we set
Emotional reasoning takes a feeling as proof of fact: I feel useless, so I must be useless. Labelling sticks a harsh global label on yourself or others from one event: I am a failure rather than I made a mistake. Should statements set rigid rules that leave you guilty or frustrated: I should always cope, I must never let anyone down. Personalisation and self-blame takes responsibility for things that are not your fault: it is my fault he is in a bad mood.
Which do you recognise in yourself?
These styles are common and completely human. Tick any that you notice yourself slipping into. There are no right or wrong answers.

When to use ‘Unhelpful Thinking Styles’
‘Unhelpful Thinking Styles’ is an interactive cognitive behavioural therapy (CBT) worksheet. As a core CBT skill it is used right across the model, with presentations including depression, anxiety, OCD, trauma and low self-esteem, rather than being tied to a single diagnosis.
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.

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, ‘Unhelpful Thinking Styles’ 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.
