IMpact of Mind-body Therapies (HYpnosis and Relaxation) on Anxiety in Children, Adolescents and Young Adults Who Had Been Treated in ONcology. Multicenter Study.

Established according to the reference scale SCARED-51 (screen for child anxiety related disorders). On this scale, each item is rated from 0 (rarely) to 2 (often), assessing the intensity of the symptom over the previous 3 months. The total score, ranging from 0 to 102 for the SCARED-R-51, is calculated by adding up the scores for all items. The higher the score, the more severe the anxiety symptoms.

Established according to the Hospital Anxiety and Depression Scale (HADS). This scale comprises 14 items: 7 items relate to anxiety and 7 others to depression, allowing two separate scores to be obtained. Each response is rated from 0 to 3 on a scale that semi-quantitatively assesses the intensity of the symptom over the past week. The score for each part (anxiety/depression) is calculated by adding the values of the responses to the 7 corresponding items. Threshold scores for the two HAD subscales have been determined with the following values: 7 or less: no case, 8 to 10: doubtful case, and 11 and above: definite case.

Established according to the reference scale CDI (child anxiety related disorders). The CDI scale comprises 27 items, each of which is scored from 0 (absent or normal behavior for age) to 2 (severe), assessing the intensity of the symptom during the previous two weeks. The total score, ranging from 0 to 54, is calculated by adding up the scores for all items. The higher the score, the more pronounced the depressive symptoms.

Established according to the Pediatric Quality of Life Inventory (PesQL). The Peds-QL measures the quality of life associated with the health status of children/adolescents in four areas: physical (8 questions), emotional (5 questions), social (5 questions), and academic (5 questions). For each question, there are 5 possible answers rated from 0 to 4 (0=never to 4=almost always) on a 5-point Likert scale or, in the version for children aged 5 to 7, 3 possible answers (0=never, 2=sometimes, and 4=almost always) on a 3-point Likert scale using smiley faces. The closer the total score, calculated as the average of all 23 questions, is to 100, the better the child/adolescent's quality of life.

Established according to the reference scale KidCOPE (Coping Orientation to Problems Experienced). It is a self-administered questionnaire that has been developed in two versions, one consisting of 15 items for children aged 7 to 12, and the other consisting of 10 items for adolescents aged 13 to 18. In both cases, two dimensions are measured: frequency and effectiveness. Frequency is measured on a 4-point Likert scale. Effectiveness is measured using a 4-point Likert scale for the version for younger children (7-12 years old) and a 5-point scale for the version for older children (13-18 years old), ranging from "not helpful" to "very helpful." The results consist of a percentage of the number of subjects using each of the different coping strategies.

Established according to the reference scale BriefCOPE (Coping Orientation to Problems Experienced). This is a self-administered questionnaire consisting of 28 items, comprising 14 scales. The 14 scales of the inventory all contain two items rated from 1 to 4 (1=not at all, 2=occasionally, 3=often, and 4=always), and the score for each scale is always between 2 and 8. The results are presented as the average score for each scale of the inventory for all subjects; there is no overall score.

The proportion of subjects aged 7 to 25 who refuse a course of treatment including psychological care will be determined by the number of refusals to participate in the study.

Non-adherence to the psychological care program proposed in this study will be determined by the termination of sessions, at the initiative of the patient or the psychologist, before reaching the minimum number of sessions required, i.e., 5 psychotherapy sessions in group 1 (arm "Usual psychological care") or 5 psychotherapy sessions combined with 5 mind-body therapy sessions in group 2 ("Usual psychological care + mind-body therapy" arm).
