Internet-based Self-help for Negative Life Events

The intervention provided is based on the principles of cognitive behavioral therapy (CBT) (Bachem \& Maercker, 2013). The manual integrates a variety of approaches validated as treatments for PTSD, anxiety disorders, or depression; the selection focuses on exercises which are intended to target the main symptoms of AjD, namely preoccupations (e.g. constant rumination, excessive worry about the stressor) and failure to adapt (e.g. sleep disturbance, difficulties concentrating, loss of interest in previously enjoyable activities).
