Neurofeedback ineffective in paediatric brain tumour survivors: Results of a double-blind randomised placebo-controlled trial.

BACKGROUND: Many paediatric brain tumour survivors (PBTS) suffer from neurocognitive impairments. Promising effects of neurofeedback (NF) on neurocognitive functioning have been reported, however research into NF for PBTS has not been conducted. We investigated the effects of NF on neurocognitive functioning in PBTS using a double-blind randomised placebo-controlled trial with a parallel-group design (Pediatric Research on Improving Speed, Memory, and Attention; the PRISMA study). METHODS: Eligible for inclusion were PBTS with neurocognitive complaints, aged 8-18 years, >2 years post-treatment. They were recruited from five medical centres in the Netherlands. A randomisation table assigned participants to 30 sessions (two per week) of either NF or placebo feedback (PF) (ratio 1:1). Participants, parents, trainers, and researchers handling the data were blinded to group assignment. Participants were assessed pre-, post- and 6 months post-training to determine whether NF training would lead to improved functioning as compared with PF training. Primary outcome measures were attention, processing speed, memory, executive functioning, visuomotor integration, and intelligence. Linear mixed models analyses were used to test differences between NF and PF training over time. RESULTS: A total of 82 children were enrolled (mean age 13.9 years, standard deviation = 3.2, 49% males); 80 participants were randomised (NF: n = 40, PF n = 40); 71 participants completed the training (NF: n = 34, PF: n = 37); 68 participants completed training and 6 months post-training assessment (NF: n = 33, PF: n = 35). Similar improvements were found over time for the two treatment groups on the primary outcomes (all p's > 0.15). CONCLUSION: Results indicated no specific treatment-effects of NF on neurocognitive functioning of PBTS.

Evaluation of a psycho-educational group intervention for children treated for cancer: a descriptive pilot study.

OBJECTIVE: The present paper reports about the content and evaluation of a psycho-educational group intervention for children growing up with a history of cancer, Op Koers Oncologie (OK Onco). OK Onco is aimed at empowerment of survivors of childhood cancer by teaching disease-related skills. The purpose of this pilot study is to evaluate whether OK Onco was appropriate for use among paediatric survivors of childhood cancer. METHODS: Eleven participating children and their parents completed questionnaires about the disease-related skills that were taught in the intervention, before the intervention and 0-4 weeks after the intervention. In addition, parents were interviewed in focus groups. RESULTS: Positive outcomes were found on most items concerning disease-related skills. Remarkable improvements were found with respect to the intervention goals 'social competence' and 'positive thinking'. The parents reported that sharing emotions and experiences with other survivors of childhood cancer was an important element of the OK Onco program, which underscores the benefit of a disease-specific program for cancer survivors. CONCLUSIONS: In conclusion, the results of the pilot study indicate that OK Onco is appropriate for paediatric survivors of childhood cancer. Implementation of the intervention is the next challenge.
