11. Compassion assertiveness
12. Wrap-up content and reflection

Inclusion criteria (obesity - as determined by body weight index and body weight shame) will be assessed over the phone as self reported measures when participant interest is expressed. Assessment items (pre and post) will be administered online via Qualtrics.

Participants attendance will be reordered via a roll check list at the start of each session by the lead researcher.

Groups will consist of approximately 6 participants as per previous research recommendations (Dutton et al 2014).
