A method used and taught by clinical psychologist and researcher Arnold Lazarus, he referred to as the step-up technique that was often used as a decatastrophisation methodology. He’d gradually step-up the level of challenge in the client’s mental imagery but they’d be coping with it adequately – it may not always have been pleasant to experience, but the client knows and understands that if such a scenario were to occur, they’d be able to cope with it. It is a great process to help those who spend a lot of time imagining the word-case scenario and it causing anxiety.
