In the face of barriers such as long waits to access evidence\u2010based treatment, perceived stigma, and a desire to tackle challenges independently, self\u2010administered single\u2010session interventions (SSIs) have arisen as one potential solution. The aim of this systematic review and meta\u2010analysis is to synthesise evidence of the efficacy of self\u2010administered SSIs for youth mental health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This random\u2010effects meta\u2010analytic review was preregistered on PROSPERO (CRD42023457030).
