Research basis
Perfectionism and procrastination are well-studied patterns that keep distress going; cognitive behavioural approaches to perfectionism have growing evidence. Behavioural experiments test predictions in real life and are an established cognitive therapy method. Cognitive behavioural therapy (CBT) has a strong research base for anxiety, depression and many related problems; this resource uses CBT techniques to support, not replace, a structured treatment plan.
