Theory based patient-education, acceptance and commitment Therapy (ACT), designed for people with type 1 diabetes

INTERVENTION: The treatment is scheduled to run over a period of (twelve months). Participants in the treatment condition will learn mindfulness and acceptance strategies to cope with diabetes related distress. The treatment will focus on living according to one’s values and on behavioural activation. As the treatment is targeted towards a population with poorly controlled diabetes, the intervention will also include one week of measurement with a hidden CGMS device facilitating for the patient to see how their behaviour influence their blood sugar levels. All sessions will be led by a psychologist with specialisation in cognitive behaviour therapy and training in ACT and a nurse specialized in diabetes. Each session will have an ACT specific theme about how to promote psychological flexibility. The topics include the acceptance of thoughts and feelings, and mindfulness. Exercise in mindfulness based in concrete practice, both during the course sessions and as homework. Acceptance practiced through experiential exercises, writing exercises and discussion. As a homework assignment to one of the visits, each patient will have to wear a hidden CGMS for a week while accurately record activity, emotion and mood. During the visit, the group participants see their blood sugar curves and linking this with their self‐registration. This is a means to gain more knowledge about the many different aspects that affect blood glucose level. At the last conversation focus will be on maintaining and continuing practice of the course content. Each patient will choose a commitment to what is important for that person to continue to focus on the next follow‐up visit Participant and recruitment Inclusion criteria for the study are that the participants are between 18 to 55 years old and have an HbA1c level >70 mmol/mol at the time of inclusion.
