Improving executive, behavioural and socio-emotional competences in very preterm young adolescents through a mindfulness-based intervention: Study protocol and feasibility
“…This study uses data collected as part of the ‘Mindful preterm teens’ study 21 , 22 . One hundred and sixty-five VPT young adolescents, i.e., born before 32 gestational weeks, were invited to participate in the study.…”

This figure shows the number of young adolescents who were enrolled into the MBI study, and of these, the number who had usable scans at both pre- and post-MBI time points and were thus included in the current analysis 21 , 22 .

“…The current study is part of a larger randomised controlled trial conducted in VPT young adolescents to evaluate the effect of an MBI on executive, behavioural and socio-emotional functioning 21 , 22 . The current study used a pre-post intervention design without a control condition due to limitations of acquiring neuroimaging in VPT young adolescents 22 ; and baseline neurobehavioural assessment was conducted in full-term young adolescents, see Fig. 2 for an illustration.…”

“…We recently reported a randomised controlled trial showing significant benefits of MBI on executive, behavioural and socio-emotional functioning in VPT young adolescents 21 , 22 . The current study aims to assess the association between the benefits of MBI on neurobehavioral functioning and changes in microstructural brain properties.…”

Very preterm (VPT) young adolescents are at high risk of executive, behavioural and socio-emotional difficulties. Previous research has shown significant evidence of the benefits of mindfulness-based intervention (MBI) on these abilities. This study aims to assess the association between the effects of MBI on neurobehavioral functioning and changes in white-matter microstructure in VPT young adolescents who completed an 8-week MBI program. Neurobehavioural assessments (i.e., neuropsychological testing, parents- and self-reported questionnaires) and multi-shell diffusion MRI were performed before and after MBI in 32 VPT young adolescents. Combined diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) measures were extracted on well-defined white matter tracts (TractSeg). A multivariate data-driven approach (partial least squares correlation) was used to explore associations between MBI-related changes on neurobehavioural measures and microstructural changes. The results showed an enhancement of global executive functioning using parent-reported questionnaire after MBI that was associated with a general pattern of increase in fractional anisotropy (FA) and decrease in axonal dispersion (ODI) in white-matter tracts involved in executive processes. Young VPT adolescents with lower gestational age at birth showed the greatest gain in white-matter microstructural changes after MBI.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
