Self-esteem is a common factor in many mental health problems, including anxiety and depression. A cognitive behavioural therapy (CBT)-based protocol called ‘Overcoming Low Self-Esteem’ is available; the use of this protocol in a group format has been associated with improvements in self-esteem. However, it is unclear whether improvements persist after the end of a group-based version of this programme.

We aimed to assess whether changes in self-esteem, anxiety and depression persist 3 months after the end of a group version of the Overcoming Low Self-Esteem programme.

Using data from the National Health Service in Fife, Scotland, we analysed whether there were improvements on self-report measures of self-esteem, anxiety and depression from the beginning of the group to the end of the group and at a follow-up session 3 months later.

Significant improvements in self-esteem, anxiety and depression are maintained at 3 months follow-up.

The Overcoming Low Self-Esteem group seems to be associated with improved self-esteem, anxiety and depression. However, further research from randomised controlled trials is needed to establish a causal link between the programme and improved psychological outcomes.
