 Behavioural assessments will take place at baseline, after the intervention, and 16 weeks after the end of the intervention. Because we believe that mindfulness-based training has the potential to affect a number of areas of life we will also look at changes in other areas of psycho-affective symptoms, social functioning, awareness, well being and quality of life, sleep quality, and cognition, after the intervention and 16 weeks after the end of the intervention. Validated neuropsychological tests and behavioural questionnaires were selected for their sensitivity to the domains listed above. These measures will be completed alone by the participant or in the presence of a psychometrist. Questionnaires will also be completed by partners at the three time points to coincide with assessments of participants.
