Results suggested the possibility that WF-CBGT may be a feasible and promising intervention for Japanese workers on leave due to depression regardless of cross-cultural differences, but that additional research examining effectiveness using controlled designs and other samples is needed. Future research should examine the efficacy of this programme more systematically to provide relevant data to aid in the continued development of an evidence-based intervention.

The use of mindfulness as a tool to improve mental health has received increased attention. Schools provide ideal environments for short-term prevention and skill development for mental health. Further, teachers can promote and reinforce students’ daily use of mindfulness. This study explored the effects of a short-term group mindfulness-based intervention on the mental health of adolescents who have experienced trauma. A total of 49 high school students received a mindfulness-based intervention session followed by homework and teacher reinforcement. The results suggest that a short-term group intervention for mindfulness can potentially improve mindfulness attention awareness and reduce depression and anxiety symptoms in adolescents. As there was no control group, additional research examining the effectiveness of the intervention is essential.

Recently, the effects of mindfulness-based interventions for posttraumatic stress disorder (PTSD) have been studied. However, we lack knowledge of the processes or mechanisms through which mindfulness influences resilience or promotes recovery following exposure to trauma. In this study, we examine the process by which mindfulness and cognitive-behavioral factors such as posttraumatic negative cognition and avoidance behaviors are associated with reduced PTSD-like symptoms. A questionnaire survey was conducted with 885 university students, using the Trauma Experience Questionnaire, Mindful Attention Awareness Scale, Cognitive Fusion Questionnaire, Post-Traumatic Stress Disorder Checklist, revised Ways of Coping Checklist, and a brief version of the Posttraumatic Cognitions Inventory. Data from 254 participants who experienced trauma with PTSD-like symptoms were analyzed. The final model using SEM indicated no direct association of mindful attention awareness on PTSD-like symptoms, a small direct association of cognitive defusion on PTSD-like symptoms, and a large indirect association mediated by posttraumatic negative cognitions and avoidance coping. Owing to the study’s cross-sectional design, strong conclusions cannot be drawn regarding the causal relationship of mindfulness and cognitive-behavioral factors or generalizations. However, our findings suggest that it would be worthwhile to continue to clarify the mechanism of mindfulness and to investigate its use in the treatment of PTSD. In the future, a highly accurate study design will hopefully be used to examine the mechanisms of several different factors associated with improvement in posttraumatic stress symptoms, preferably including them in the same model.
