Cognitive Diary CBT Self-Help

Cognitive Diary CBT Self-Help aims to help users identify and change problematic thinking that can occur with a variety of mental illnesses. In the ‘Cognitive Diary’ section of the app, users record bothersome or problematic events and rate the level of distress the event caused. They list the thoughts that occurred during the event, the percentage of thoughts they believe, and the irrational beliefs they had. Users then identify the positive thoughts they had (e.g. “I handled that well”) and write some positive feedback or outcomes from the event, before rating their distress again. There is also an ‘Articles’ section which provides some information on the principles of Cognitive Behavioral Therapy (CBT) as a helpful tool for overcoming mental illness.
