Here is the design of a clinical trial:

Official Title: ICT-enabled Social-emotional Learning: Development of Responsibility and Well-being in the Educational Environment

Included conditions:
- Adolescent - Emotional Problem

Study Armgroups:
- {'label': 'Intervention group', 'type': 'EXPERIMENTAL', 'description': 'During the tutoring time, the intervention program is carried out in the experimental group, through emoTIC. EmoTIC is an emotional education program focused on the development of social-emotional competences through an application that can be used in mobile devices and tablets.', 'interventionNames': ['Other: ICT-enabled Social-emotional Learning']}
- {'label': 'Control group', 'type': 'NO_INTERVENTION', 'description': 'During the period in which the intervention program is conducted in the experimental group, the control group will remain in the waitlist (will not participate in the intervention), and will carry out the program once the study is finished.'}

Interventions:
- {'type': 'OTHER', 'name': 'ICT-enabled Social-emotional Learning', 'description': 'ICT-enabled Social-emotional Learning', 'armGroupLabels': ['Intervention group']}

Primary Outcomes:
- {'measure': 'Emotional Intelligence', 'description': 'Trait Meta-Mood Scale (TMMS-24)', 'timeFrame': 'Time 1 (first month)'}
- {'measure': 'Emotional Intelligence', 'description': 'Trait Meta-Mood Scale (TMMS-24)', 'timeFrame': 'Time 2 (4th month)'}
- {'measure': 'Emotional Intelligence', 'description': 'Trait Meta-Mood Scale (TMMS-24)', 'timeFrame': 'Time 3 (up to 1 year)'}
- {'measure': 'Subjective Well-Being', 'description': 'Life satisfaction and positive and negative affects', 'timeFrame': 'Time 1 (first month)'}
- {'measure': 'Subjective Well-Being', 'description': 'Life satisfaction and positive and negative affects', 'timeFrame': 'Time 2 (4th month)'}
- {'measure': 'Subjective Well-Being', 'description': 'Life satisfaction and positive and negative affects', 'timeFrame': 'Time 3 (up to 1 year)'}
- {'measure': 'Emotional Competence', 'description': 'Emotional Skills and Competence Questionnaire', 'timeFrame': 'Time 1 (first month)'}

Please estimate the sample size based on the assumption: 
95% confidence level, 5% margin of error.
Sample size
        According to the National Statistics Institute,36 the population of adolescents (10â19âyears) in Spain is 4â912â519. By choosing a 95% confidence level and a 5% margin of error, the representative sample size would be 385 participants. Participants will be randomly assigned to the control group and the experimental group using a computer-generated random numbers. The allocation sequence will be computer generated using a purpose-built application.
