Original Title: e proximité en santé mentale pour la clientèle adolescente : Modalités et approches dans un contexte de rareté des ressources

Authors' objectives: This ETMISSS project was conducted to answer the following question: What are innovative outreach modalities and approaches are there for treating adolescents with mental health symptoms or disorders?

Authors' results and conclusions: Of the 2 566 potentially eligible documents, 23 studies with 22 interventions were selected for the review. Overall, face-to-face interventions were found to improve depression and/or anxiety. There were also positive effects on global functioning and psychosocial problems. The impact of digital interventions or programs appears to be more heterogeneous. Programs based on or including cognitive behavioral therapy (CBT) showed that a greater reduction in depressive or anxiety symptoms correlated with participants attending more sessions. Two hybrid interventions, carried out both face-to-face and digitally, demonstrated a reduction in depressive symptoms. Twenty-two interventions and innovative programs, delivered in different modalities, could be offered to adolescent clients in community mental health services. Face-to-face interventions delivered by various professionals seem to be the most effective at reducing symptoms of depression and anxiety in young people. However, digital interventions are an interesting avenue to explore. Further research is needed to confirm the effectiveness of these interventions.

Authors' recommendations: • Digital and hybrid face-to-face interventions in clinical, school, and community settings have been identified as effective methods for delivering mental health outreach services to adolescents; • Many community mental health interventions are based on CBT to treat adolescents; • The duration of these interventions varies from three to 12 weeks; • The professionals most often involved are psychologists, general practitioners, and psychiatrists; • Parents or relatives may be involved in certain interventions. They may participate as service providers or support their child during treatment; • Face-to-face interventions appear to be the most effective way to reduce depression and anxiety, regardless of the setting; • Various forms of CBT can help reduce symptoms of depression and anxiety; • Interventions based on approaches other than CBT can improve mental health symptoms in adolescents; • Numerical approaches show some efficacy in reducing anxiety, and their effectiveness varies according to how many sessions young people attend; • Hybrid interventions, which combine at least two types of interventions, are no more effective than face-to-face or digital interventions; • No study has specifically addressed the safety of interventions; • Measures to ensure the confidentiality and safety of young people during face-to-face interventions have been reported; • Digital studies address the issue of securing access to digital platforms.

Authors' methods: A systematic review of the scientific literature was carried out using the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) method to formulate finding. Literature search strategies were employed to query the CINHAL (EBSCO), Medline (OVID), Embase (OVID), and PsychINFO (OVID) bibliographic databases. Documents identified during the literature search were selected based on inclusion and exclusion criteria determined using the PICOTS tool. Relevant data were extracted using a structured grid. The interventions identified in the literature were grouped according to their delivery modality: face-to-face, digital, or hybrid (more than one approach simultaneously).
