Emotional disorders (e.g., anxiety disorders, depression), is the most common psychological disorders across different countries, while the global clinical professional capacity is relatively weak. In order to treat
these disorders and sub-health state more efficiently,
Mindfulness Intervention for Emotional Distress (MIED) was developed, based on Mindfulness-based Stress Reduction (MBSR) and Unified Protocol for transdiagnostic treatment of emotional disorders (UP). Compared to other mindfulness-based interventions or UP, the MIED includes transdiagnostic Psychopathological
Diamond Model and the corresponding four core intervention strategies. A series of studies indicated that both the eight-week MIED intervention led by professionals and/or the online digital self-help intervention program iMIED (Internet Mindfulness Intervention for Emotional Distress) with only limited professional support have effectively alleviated the symptoms of patients with anxiety and depressive disorders or individual participants in subhealth. Moreover, mindfulness, experiential avoidance, distress tolerance, and decentering are potential mechanisms of action, which initially support the Psychopathological Diamond Model of MIED.
