Details of the Quality of Life in Motion (QLIM) psychosocial intervention.

Psychosocial training modules	Includes 6 child sessions and 2 parent sessions.
Session 1 (1 h)	In the first module the focus is on increasing self-awareness and belief in one's own competency. During an exercise, the patient is stimulated and supported to express positive things about him/herself.
Session 2 (1 h)	The second module focuses on feelings, thoughts, and behaviour. The central themes are the four basic feelings of a human being: fear, anger, happiness and sadness.
Session 3 (1 h)	In the third module coping with (non) disease-related difficult situations is the main topic. Also, training in relaxation exercises is given.
Session 4 (1 h)	The fourth module focuses on social contacts with peers. Does the disease influence their social relationships? For the older age group, sexuality and relationships are also addressed.
Session 5 (1 h)	The fifth module focuses on possible changes in the family after the diagnosis of cancer, i.e. changes in relations with siblings and parents, and separation-individuation problems.
Session 6 (1 h)	The sixth session deals with the future and how to incorporate physical exercise in daily life from now onwards.
Parent session 1 (1 h)	The first parent session focuses on the principles of the program to increase parental support, in order to improve compliance and endurance.
Parent session 2 (1 h)	The second and last parent session focuses on evaluation of the total program. Parents and therapists describe the achieved goals and the changes observed during the program.
