Research procedure. Subjects interested in participation receive online screening questionnaires. Eligible subjects then are asked to sign informed consent, fill in the baseline questionnaires and take part in a diagnostic interview via telephone.

Subjects of the control group get access to the intervention (self-help) following the last assessment.
