The Short Version
The evidence does not support this claim. While India has studies on adolescent emotional regulation broadly (e.g., school-based life skills programs), these do not measure suicide risk as an outcome. The only India-linked suicide/self-harm intervention identified (ATMAN) is a mixed-method case series, not an RCT or quasi-experimental study, and its authors explicitly call for future RCT evaluation. WHO India, targeted PubMed searches, and peer-reviewed LMIC syntheses all confirm a scarcity of qualifying trials meeting the claim's specific criteria.
