Virtual mind-body treatment for adolescents with neurofibromatosis: Study protocol for a single-blind randomized...

Neurofibromatoses (NF) are a group of genetically distinct disorders of the nervous system unified by the predisposition to nerve sheath tumors. Although adolescents with NF types 1 and 2 (NF1 and NF2) report poor quality of life and high psychosocial burden, there are no evidence-based interventions to address these needs. This paper presents the study design and protocol for the first randomized controlled trial (RCT) of a mind-body intervention for adolescents with NF, Resilient Youth with NF (RY-NF), versus an educational control group, Health Education for NF (HE-NF), both delivered in groups via secure live video.

This is an ongoing, single-blind efficacy RCT. Recruitment began in November 2019 and will continue until March 2022. We will enroll 200 English-speaking, geographically diverse adolescents (ages 12-17) with NF1 and NF2 who report significant distress or difficulty coping with their NF symptoms. We will use a shared-baseline, linear mixed model to compare the effect of RY-NF versus HE-NF on changes in quality of life (QoL) and psychosocial outcomes from baseline to post-intervention, and 6- and 12-month follow-ups. We will also develop NF-specific minimal clinically important difference (MCID) for QoL variables, and conduct mediation and moderation analyses to understand mechanisms of improvement.

This study has important clinical and public health implications for the psychosocial functioning of adolescents with NF. It provides a model for efficient delivery of virtual psychosocial care for adolescents with rare diseases. Plans for dissemination and implementation of the RY-NF should efficacy be ascertained are also discussed.
