Internet-Based Cognitive Behavioral Therapy With Treatment as Usual for Generalized Anxiety Disorder and Major Depressive Disorder in Taiwan (ICBT-TW)

An 8-week Internet-based Cognitive Behavioral Therapy (ICBT) program delivered via the National Health Research Institutes (NHRI) secure online platform. The program consists of 12 sequential modules released every 5 days, covering core CBT techniques such as cognitive restructuring, emotion regulation, behavioral activation, mindfulness, and self-compassion. Participants receive automated email notifications for new modules and supplementary review materials. Progress is monitored through the platform, and participants complete standardized self-report assessments at baseline, mid-intervention (week 5), post-intervention (week 9), and 3-month follow-up.

Routine clinical care provided by a psychiatrist, which may include pharmacological treatment, psychoeducation, and regular follow-up visits according to clinical judgment. No ICBT intervention is provided during the study period. Participants follow the same assessment schedule as the experimental group. After the 3-month follow-up, participants in this group may request access to the ICBT program.
