Sibling Group for Children and Teenagers Living With a Sibling Who Suffers From Anorexia Nervosa: a Pilot Acceptability Study

AN has a significant impact on nuclear family (parents and siblings). An emerging literature highlights the need for a particular attention to siblings. Despite this evidence, research and clinical applications still lack in this area. Indeed, most of health services in AN offer support for patients, family, parents, but only few specific support for siblings, although positive outcomes of sibling group interventions were reported in other somatic and psychic disabilities.

Noting the gap between the need and the lack of specific support, the study hypothesis is that the poor diffusion of these interventions in AN might result from a low acceptability. The study propose to explore acceptability to adapt and improve group intervention for siblings of children and teenagers receiving care for anorexia nervosa.

The study is a mixed-method pilot study assessing the acceptability of a group intervention by including a maximum of 24 siblings of children suffering from AN, aged from 8 to 18, across three group sessions, each consisting of 4 meetings. All participants will be invited to fulfill two different auto-questionnaires about their quality of life (before and after group session) and the intervention's acceptability (after group session).

Quantitative data will be complemented with qualitative data, collected from individual semi-structured interviews with a targeted sampling among group participants.
