Effectiveness of Group Cognitive Behavioral Therapy for Psychological Sub-health

Mental health has become an increasing concern, especially since the beginning of the COVID-19 pandemic. However, not all individuals in mental suboptimal states require pharmacological treatment. Cognitive Behavioral Therapy（CBT） can achieve its therapeutic effect by improving activation patterns of the brain's internal networks to promote self-regulation. The study was designed as a randomized clinical trial with two groups, the GCBT group and the Waiting group, in a state of mental subluxation. the GCBT group received both self-help therapy and on-site guidance, while the Waiting group received the GCBT intervention after treatment in the GCBT group. Data collection was conducted by trained, certified and qualified personnel. The study was designed to use assessment wearable devices (WD) and mobile apps (MA) for behavioral data and EMA collection during treatment, and the extracted behavioral characteristics were used as objective indicators for long-term and short-term efficacy assessment of GCBT, further understand the possible biological mechanism underlying the efficacy of GCBT by analyzing digital biomarkers.
