Sessions comprise of studying course material, group discussions, experiential contemplation/meditation, calm-abiding meditation and gentle movement-based exercises. Facilitators will promote participant Reflective Functioning through explicit mentalising as theoretically taken from Mentalising Based Therapy.

6- Self vs person Participants explore sense of self as a construct. Highlighting the psychological benefits of experiencing themselves as a ‘whole person’
7-Cause and effect In-depth exploration of causes and conditions that maintain ED

9- Path to recovery Participants discuss application of skills learned in the course. Participants are guided to understand how to apply these skills in systematic, sustainable manner to work towards recovery
10- Compassion Participants are guided on how to utilise an ‘other regarding’ attitude skilfully. Support and guidance is further given for applying the ‘path’ to recovery

Participants will be given activities to complete between therapy sessions. Activities given to participants to undertake between sessions include meditation, gentle movement based activities, self-soothing activities (when distressed), and mindfulness to become aware of psychological functioning in relation eating disordered pathology.
Participant adherence to the intervention will be monitored via an attendance checklist and a self-report record book of daily usage/ practicing of skills taught in the intervention. The facilitating psychologist adherence will be monitored through all therapy sessions being audio recorded and 20% of sessions being reviewed by an independent party for fidelity to the manual.
The intervention will be conducted by a registered psychologist with expertise in eating disorder treatment. The psychologist is a registered member of Australian Psychological Society and Australian Health Practitioner Regulation Agency.
Experiential Awareness Therapy is a 10 session manualised group therapy, ran over ten weeks. Each session runs for 2 hours.
Sessions will be delivered in person to groups of approximately 10 participants. Sessions will be delivered within a private therapy space.

Statistical methods / analysis
T-tests will be conducted on pre and post measures and between measures. For an assumption of power .80, P<.05 for a sample n=30, effective size of d=.55 must be found in outcome measures. Effects sizes d=.55 are commonly reported in ED trials.
The amount of time practicing skills will be turned in categorical data. An ANOVA will be conducted to determine if there are difference in outcomes based on level of practice. A post-hoc test, Tukey’s honestly significant difference test, will be conducted if any significant differences occur.
