Acquired brain injury (ABI) in childhood are the cause of disabling motor, cognitive and behavioural disorders, with severe consequences on the later development of autonomy and learning, with long-term repercussions on independence for activities of daily living, and social and professional integration.

Among cognitive disorders, executive function (EF) deficits are among the most frequent and disabling, with major consequences on the development of autonomy and the course of schooling and learning.

The Cognitive Orientation to daily Occupational Performance (CO-OP) could be an interesting approach for the rehabilitation of these consequences. CO-OP is a performance-based treatment approach for children and adults who experience difficulties performing the skills they want to, need to or are expected to perform. CO-OP is a specifically tailored, active client-centered approach that engages the individual at the meta-cognitive level to solve performance problems. Focused on enabling success, the CO-OP approach employs collaborative goal setting, dynamic performance analysis, cognitive strategy use, guided discovery, and enabling principles.

It has been shown to be effective in a variety of populations, but has been little explored in children with ABI. The hypothesis that CO-OP is effective in improving the occupational performance and executive functioning of these children on a daily basis is emerging, but needs to be confirmed. This study falls within this framework.

Primary objective:

1. To measure the distance maintenance of the knowledge acquired through rehabilitation, as well as the generalization and transfer into everyday life.

   1. Maintenance of acquired knowledge
   2. Generalization and transfer
   3. Impact of a consolidation session on generalization and transfer

   Secondary objectives:

2. Gather the experience of family members/caregivers in accompanying their child in the CO-OP process outside of rehabilitation sessions.

3. Establish the parental educational style and identify whether there is a link between the parental educational style and the commitment of the family members/caregivers.

Twelve participants will be included (aged 8 to 21 years old). Participants will have different assessment times, before, during and after the CO-OP intervention (immediate post-intervention, 2, 4 and 6-months post-intervention). Parents will be asked to answer questionnaires and interview and to participate in certain CO-OP sessions, if they can.

They will choose four objectives (problematic everyday life activities they want to improve). Three will be worked on in CO-OP sessions, the fourth will be the control objective.

The duration of the baseline, as well as the order of introduction of the objectives and the starting point of the objectives, are randomized.

Participants will have 14 sessions of rehabilitation with the CO-OP approach (2 sessions per week for 7 weeks).

Inclusion Criteria:

1. Child/adolescent/young adult aged between 8 and 21 years old, hospitalized in the Acquired Neurological Pathologies Service of the Saint-Maurice Hospitals or in the Medical and Pedagogical Centre for Adolescents of Neufmoutiers-en-Brie, and possibly schooled in this service.
2. Diagnosis of acquired brain injury, for at least 6 months.
3. Child/adolescent/young adult presenting executive function deficits as determined by the neuropsychological assessment (standardized tests and/or questionnaire).
4. Vision and hearing normal or sufficient to communicate effectively (with appropriate correction if necessary).
5. Having sufficient speaking and comprehension skills to communicate effectively and accurately.
6. Enrollment in a Medicare plan or eligible beneficiary.
7. Agreement of the child/young person and informed consent expressed by the holders of parental authority. Consent of the young adult (18-21 years of age).

Exclusion Criteria:

1. Non-Francophone child/teenager/young adult and/or non-Francophone parents.
2. With an intellectual disability (total IQ <70), or severe impairment in comprehension, memory or attention, not compatible with understanding the goals of the rehabilitation and participation in 45-minute sessions.
3. Neurological, psychiatric, genetic or learning disorder diagnosed prior to the occurrence of the acquired brain injury.
4. Severe anxiety and/or depressive disorder diagnosed that is not compatible with participation in the study.
5. Inability to commit until the end of the CO-OP rehabilitation phase (e.g., planned relocation, planned hospital discharge before the end of the 14 CO-OP sessions, i.e., 10 weeks including baseline and CO-OP rehabilitation).
6. Major subject under guardianship or curatorship.

We think it would be interesting to share the IPD with other researchers (especially Canadian researchers), but we have not yet defined the terms of this sharing.
