Teachers' emotional competence predicts teachers' mental health and the teacher-student relationship. Therefore, training pre-service teachers' emotional competence seems important. In the present study, we evaluated a training of emotional competence comprising elements of emotion knowledge, emotion awareness, and emotion regulation training. We report on data of 186 participants and compared 71 trained subjects to two comparison groups. We found some effects of the training on both self-estimated and objectively measured emotion regulation ability. These effects remained stable over time. Further-more, we found that the in-situation emotion insecurity decreased only in the training group. Future implications of these results are discussed.(c) 2022 Elsevier Ltd. All rights reserved.
