Single-Session Interventions for Adolescent Mental Health
Summary
Single-session interventions (SSIs) represent a streamlined approach to delivering psychological support in one concentrated encounter. Originating in response to widespread service gaps and barriers to care, SSIs aim to provide immediate, evidence-based strategies for adolescents experiencing distress. They encompass diverse modalities, including self-guided digital platforms, problem-solving exercises led by brief professional contact and immersive virtual reality experiences. SSIs have been deployed in schools, community settings and online, offering low-intensity yet potent tools to address symptoms of depression, anxiety and related psychosocial difficulties. By focusing on core therapeutic elements—such as cognitive reappraisal, skill building and empowerment—SSIs seek to bridge the transition to more intensive treatments or to serve as stand-alone supports. Early findings highlight consistent reductions in hopelessness, self-criticism and behavioural activation deficits, alongside improvements in perceived control and agency. Key challenges for broader uptake include ensuring cultural relevance, maintaining engagement in self-guided formats and embedding SSIs within stepped care systems to optimise long-term outcomes. The global significance of SSIs lies in their potential to extend reach, reduce waiting lists and engage marginalised youth who might otherwise forgo conventional therapy.

Technical terms
Single-session intervention (SSI): A therapeutic approach designed to deliver a complete, stand-alone session of psychological support.
Self-guided intervention: A format in which participants independently complete therapeutic activities without real-time professional guidance.
Stepped care model: A hierarchical system of service delivery that matches intervention intensity to individual need, progressing from low-intensity to specialist treatments.
