A JAMA study finds the 988 Suicide & Crisis Lifeline reduced suicide deaths among U.S. teens and young adults versus modeled expectations after launch, adding measurable support to a federal investment that faces long-term funding questions. Researchers compared observed suicide mortality for ages 15 to 23 from July 2022 through December 2024 with modeled estimates had 988 not launched, reporting an 11% reduction—equivalent to roughly 4,400 fewer deaths than projected. Lead author Dr. Vishal Patel (Harvard Medical School) said the $1.5 billion cumulative federal investment appears to have translated into measurable reductions. The study cannot prove 988 caused the full decline, but it reports “gut check” comparisons and notes that states with the largest post-launch call volume increases also showed larger gaps between expected and actual deaths. While U.S. overall suicide rates have also declined, the findings still strengthen the case for keeping crisis staffing and technology support in place as states and institutions confront rising student mental health needs.
