About this study

Official title: DEVELOPMENT AND EVALUATION OF A MULTIFACETED SCHOOL-BASED INTERVENTION TO PROTECT MENTAL HEALTH AND PREVENT SUICIDAL BEHAVIOR AMONG ADOLESCENTS IN SPAIN

What is this study about? This study aims to find out if a school-based program can help improve mental health and prevent suicidal thoughts and behaviors in teenagers in Spain. Suicide is one of the leading causes of death among young people. Many teens who think about or attempt suicide are also struggling with mental health problems like depression. Schools offer a unique opportunity to help because almost all adolescents attend school regularly.

What will happen in the study?

Read more

The study will include about 2,280 students aged 12 to 16 years from 38 secondary schools in the Balearic Islands, Spain. Schools will be randomly assigned to one of two groups:

Intervention group: Students will participate in four weekly classroom sessions led by trained psychologists. These sessions will help students learn about mental health, manage their emotions, recognize signs of distress in themselves or others, and ask for help when needed. At the same time, parents and teachers will follow a digital training program with videos and resources to help them support students' mental health and recognize warning signs.

Control group: Students will receive a minimal intervention, which includes educational posters displayed in classrooms.

What is the purpose of this program? The main goal is to reduce suicidal thoughts and behaviors. The program also aims to improve students' overall mental well-being, reduce depression symptoms, and encourage help-seeking behaviors. It also helps parents and teachers feel more confident in supporting teens who may be at risk.

How will the study be evaluated? Students will complete questionnaires at the start of the study and again after six months. These surveys will ask about mental health, suicidal thoughts, emotional well-being, self-harm, substance use, and experiences with bullying. Parents and teachers will also complete surveys about their knowledge and confidence in supporting students.

Why is this study important? There is an urgent need to find effective ways to prevent suicide and support young people's mental health. This program involves students, families, and schools in working together to create a safe and supportive environment. If the program works, it could be used in schools throughout Spain and possibly in other countries too.

Who is funding this study? The study is funded by Fundación Mutua Madrileña.

Read the detailed description

Background Adolescent suicide is a critical public health concern and one of the leading causes of death among youth globally. In Spain, suicide has been the primary external cause of death since 2008. Rates are especially concerning among adolescents and young adults. Depression and other mental health disorders are major risk factors associated with suicidal thoughts and behaviors in this population.

Schools provide a strategic setting for suicide prevention and mental health promotion, as they offer direct and repeated access to adolescents during a critical stage of emotional development. The involvement of teachers and families is also crucial, as they play a key role in identifying and supporting students at risk.

This study is a two-arm, cluster-randomised controlled trial designed to evaluate the effectiveness of a multifaceted school-based intervention to reduce suicidal ideation and behavior and promote mental health in adolescents aged 12 to 16 years. A total of 38 secondary schools in the Balearic Islands, Spain, will be randomly allocated in a 1:1 ratio to either the intervention or control group, with 2,280 students expected to participate.

Intervention Description

The intervention comprises two components:

  1. Student-focused psychoeducational program: Delivered by trained psychologists in four weekly classroom sessions (90 minutes each), this component is based on a comprehensive model of suicide prevention and mental health promotion. The sessions include:
  • Mental health literacy and stigma reduction
  • Emotional regulation and coping strategies
  • Recognition of warning signs and crisis response
  • Promotion of help-seeking behavior and strengthening of social support networks Sessions incorporate dynamic group activities to enhance engagement and learning. The program is designed to foster a safe environment for sharing and reflection.
  1. Digital co-intervention for parents and teachers: Delivered through a custom-built digital platform, this component includes four knowledge modules with videos, podcasts, and additional educational resources. The content aligns with the student sessions and aims to improve suicide-related knowledge, reduce stigma, increase self-efficacy, and support identification and referral of at-risk students. Access to the platform is monitored through user self-reports and automated engagement tracking.

The control group will receive a minimal intervention in the form of educational posters on mental health and suicide prevention placed in classrooms.

Outcomes and Data Collection Primary and secondary outcomes will be assessed using validated instruments at baseline and six-month follow-up. Primary outcomes include suicidal ideation and behavior. Secondary outcomes include symptoms of depression, psychological well-being, self-harm, substance use, internet addiction, bullying, and help-seeking behaviors. Teachers and parents will report on suicide-related knowledge, self-efficacy, and student referrals.

Process evaluation will be conducted through qualitative interviews with a subsample of students, parents, and teachers to assess the implementation, acceptability, and perceived impact of the intervention.

Data will be analyzed using generalized linear mixed models to account for the clustering of students within schools. Multiple imputation will be used to address missing data. The primary analysis will follow an intention-to-treat approach.

Significance This study addresses a critical gap in the evidence base for suicide prevention programs in Spain. It aims to provide robust data on the effectiveness of a scalable, cost-effective, and digitally enhanced intervention. If successful, the intervention may support wider implementation in schools and contribute to improved mental health outcomes and suicide prevention strategies at the national level.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Severity of Suicidal Ideation

    Change in the severity of suicidal ideation as assessed by the Spanish version of the Suicidal Paykel Scale. This 5-item scale evaluates the presence and intensity of suicidal thoughts over the previous year. Responses are dichotomous (Yes/No) and produce a score ranging from 0 (no ideation) to 5 (high severity). A higher total score indicates greater suicidal ideation severity.

    Measured: Baseline and 6-month follow-up

Secondary outcomes (8)
  1. Suicide Attempts

    Proportion of students reporting a suicide attempt in the past year, assessed through item 5 of the Suicidal Paykel Scale ("Have you ever tried to end your life?").

    Measured: Baseline and 6-month follow-up

  2. Depressive Symptoms

    Severity of depressive symptoms measured using the Spanish version of the Beck Depression Inventory-II (BDI-II), a 21-item questionnaire. Scores range from 0 to 63, with higher scores indicating greater symptom severity.

    Measured: Baseline and 6-month follow-up

  3. Well-being

    Subjective well-being measured using the Spanish version of the WHO-5 Well-Being Index, a 5-item scale with scores ranging from 0 (worst) to 25 (best).

    Measured: Baseline and 6-month follow-up

  4. Self-Harm

    Incidence and characteristics of self-injury behaviors assessed using the 15-item Spanish version of the Self-Harm Questionnaire (DSHI). Includes method, frequency, motivation, and context of self-harm.

    Measured: Baseline and 6-month follow-up

  5. Internet Addiction

    Problematic internet use assessed using the Spanish version of the Internet Addiction Test (IAT), a 20-item measure with scores from 20 to 100.

    Measured: Baseline and 6-month follow-up

  6. Substance Use

    Risk of substance use disorder measured using the Spanish version of the CRAFFT Screening Test. Scores range from 0 to 6; scores ≥2 indicate high risk.

    Measured: Baseline and 6-month follow-up

  7. Bullying Involvement

    Bullying experiences assessed via the Bull-S Test, which includes peer and teacher nominations to identify victims and aggressors within the classroom.

    Measured: Baseline and 6-month follow-up

  8. Help-Seeking Behaviors

    Student-reported intentions and behaviors related to seeking help for mental health issues, collected through study-specific questionnaires.

    Measured: Baseline and 6-month follow-up
