This randomized controlled trial aims to evaluate the efficacy of a universal intervention based on Natural Psychotherapy in reducing anxiety and depressive symptoms among primary and middle school students. To evaluate both the clinical outcomes and the potential underlying mechanisms of change, data will be collected at four distinct time points: baseline (pre-intervention), post-intervention, 3-month follow-up, and 6-month follow-up.
Objective 1: Evaluate the Efficacy of Natural Psychotherapy on Primary Outcomes (Anxiety Symptoms and Rumination) To evaluate the short-term and sustained efficacy of the Natural Psychotherapy program in reducing anxiety symptoms and maladaptive rumination among primary and middle school students compared to standard schooling.
Objective 2: Assess the Impact on Secondary Outcomes (Psychological Well-being, Emotional Regulation, Stress, Sleep, Self-Esteem, Depression, Life Satisfaction, and Social Support) To assess the effects of the Natural Psychotherapy program on secondary psychological outcomes, including mindfulness, perceived stress, resilience, insomnia severity, self-esteem, depressive symptoms, life satisfaction, eudaimonic well-being, and perceived social support, and to examine whether improvements in these domains mediate the primary outcomes.
Objective 3: Explore the Mechanisms of Change and Predictors of Treatment Response To explore the underlying psychological mechanisms through which Natural Psychotherapy produces its therapeutic effects on primary outcomes (anxiety and rumination) and to identify baseline predictors and moderators of treatment response.

Start is estimated for Sep 2026; primary completion for Jul 2027, 10 months later.
Of 3,836 non-industry interventional studies with no phase under Anxiety Disorders, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 28. This study's planned 10 months is below that.
Counting every sponsor, half of 3,938 studies reached it within 12 months; a quarter within 5 and three quarters within 28.
