Strengthening Emotional Regulation: a Group Intervention With Adolescents

The goal of this clinical trial is to determine the initial efficacy of an emotional regulation skills training (ERST) intervention program in a group of adolescents presenting mild symptoms affecting their ability to regulate emotions. For this purpose, a sample of 1st and 2nd-year high school students (ages 14-16) will be recruited, and the intervention will be conducted on the educational institution\'s premises during school hours. The main questions it aims to answer are: Does the ERST intervention reduce symptom levels in adolescents with mild emotional dysregulation? Does the ERST intervention improve emotional regulation skills in adolescents? Researchers will compare pre-intervention (T1) and post-intervention (T2) outcomes, as well as follow-up assessments at 3 months, to evaluate changes in symptom levels and emotional dysregulation. Additionally, a blinded teacher assessment will be conducted at T1 and T2 to evaluate symptom levels. Participants will: Attend the ERST intervention sessions during school hours. Complete self-report assessments at four time points (T1, T2, and 3-month follow-up). Be evaluated by a blinded teacher at T1 and T2.
