Burnout Prevention and Sustainable Performance for Vietnamese Adolescents Under High-Stakes-Exam Pressure: Structural Drivers, Evidence-Based Prevention Practices, and

The Layer I guidance series targets Vietnamese adolescents 14–19 in a population where school burnout, sleep deprivation, and academic-pressure-related distress are non-trivial and concentrated in the kỳ thi tốt nghiệp THPT preparation cycle. Paper i5.1 supplied the prevalence grounding and the selfhelp-versus-clinical scope-of-help boundary. This paper takes the construct of student burnout in the Schaufeli-Salanova / Salmela-Aro / Maslach-Leiter sense and builds the preventionand-recovery pedagogy that sits inside that boundary. Three questions are addressed. (a) What does the student-burnout and sustainable-performance literature say about prevention and recovery, distinct from clinical depression treatment? Burnout is a syndrome of emotional exhaustion, cynicism toward schoolwork, and reduced sense of academic efficacy that arises from sustained mismatch between demands and resources [1], [2], [3]; prevention operates upstream on demands and resources; recovery operates on detachment, sleep, and resource replenishment [4], [5]. (b) What are the structural drivers in Vietnamese exam culture that prevention must address? The kỳ thi tốt nghiệp THPT preparation cycle, chuyên-school workload, parental and teacher pressure cascade, peer hierarchy in selective tracks, and the cumulative displacement of sleep, exercise, and relationships are the load-bearing drivers; sleep deprivation in particular is documented as a mediating mechanism with strong effect-size [6], [7]. (c) What is the operational prevention curriculum, teachable in a textbook chapter? The substantive operational artefact is the Practice × Evidence × Deployability table (§V) which ranks eleven prevention practices. Sleep, exercise, studyload regulation, and recovery-detachment carry the strongest evidence and best deployability; self-compassion [8], [9], [10], social support, mastery-vs-performance goal reorientation, and time management are second-tier; mindfulness and gratitude practices are third-tier with explicitly bounded effect-sizes. Mindfulness is presented as one bounded tool, not the keystone — the Goyal 2014 JAMA Internal Medicine meta-analysis reports modest effect-sizes for mindfulness on stress in adults (d ≈ 0.30 versus active control) [11], and the adolescent-school-setting meta-evidence [12], [13], [14] shows weaker, less robust effects than the popular literature claims. Productive struggle (Bjork desirable difficulty) is distinguished from chronic burnout; the paper does not pathologise effort. The deliverable is operational prevention curriculum content for an adolescent reader — not
