Screening and Monitoring of Mental Health in Educational Settings: Programme for Detection, Psychoeducation and Self-help

Adolescence is a critical developmental stage during which many mental health problems first emerge. However, a large proportion of these issues go undetected and untreated. Globally, approximately one in seven adolescents experiences mental health difficulties, with increasing trends observed in recent years. Schools offer an important setting for early detection and intervention, yet existing programmes often lack structure or scalability. The MENTOR programme (MENtal Health Tracking, Outreach and Referral) was designed to identify adolescents under psychological distress in educational settings and offer tiered support including psychoeducation, self-help tools, and referral to mental health services when needed. This is a prospective, longitudinal, multicentre study that will be implemented in eight educational centres in Spain, including secondary schools, sixth-form colleges, and vocational training centres. Adolescents and young adults will be invited to participate voluntarily. At baseline and at each trimester, participants will complete validated mental health screening tools assessing common conditions such as anxiety, depression, and emotional dysregulation. Based on results, participants will be assigned to one of several support pathways: access to digital self-help materials, small-group interventions, or referral to school-based or external mental health professionals. Follow-up assessments will measure changes in symptomatology, engagement with self-care tools, and help-seeking behaviour. Quantitative data will be analysed to assess feasibility, adherence, and effectiveness of the intervention over time, and conduct a cost-effectiveness analysis This protocol aims to improve adolescent mental health through a school-based, digitally delivered screening and intervention programme. By evaluating feasibility and acceptance across eight educational centres, the study seeks to generate real-time data on prevalent mental health issues, promote awareness and self-care, and facilitate early professional intervention. If effective, the programme could support scalable, tiered prevention strategies in educational settings, contributing to reduced rates of anxiety, depression, suicidal ideation, eating disorders, and addictions. Its implementation may also improve resource allocation, reduce wait times, and inform future health policies for longitudinal mental health monitoring from childhood. Findings will contribute to the development of accessible, evidence-based models for adolescent mental health promotion and early intervention.
