A sample of adolescents ( n = 40, Mage 16.7) was randomly assigned to experimental and control groups. There were 10 participants in each four groups. The embedded design with a convergent approach was used. The quantitive data were obtained using the Solomon four group design while the qualitative data were obtained with phenomenological approach. The mindfulness-based intervention consisting of eight sessions and seven workshops was applied online to the experimental groups. The findings revealed that the attentional control and mindfulness levels of the adolescents in the experimental groups were significantly higher compared to the adolescents in the control groups.
