“…The newly added mindfulness program modules (e.g., focused attention, deep breathing, cultivating a kind attitude toward self and others, setting positive intentions) draw on youthspecific adaptations of mindfulness-based interventions (such as the 8-week curriculum of mindfulness-based cognitive therapy, MBCT), but will be relatively brief compared to other formal mindfulness interventions, and will be designed to reflect age-related developmental needs and characteristics of youth 10-14 years old (e.g., with regard to attention span, cognitive capacities, language, physicality, relevant content, time involved in the intervention, and home practice in a situation with competing time demands). The selection of age-appropriate mindfulness modules for our targeted population builds on the current knowledge base of mindfulness training in non-clinical youth populations, which mainly derives from established school-based approaches [71], such as the "Learning to Breathe" manual [72,73] and other programs [74,75].…”
