Evaluation of a Video-based Internet Intervention as Preparation for Inpatient Psychosomatic Rehabilitation

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the effect of an internet-based preparation on the outcome expectancy and treatment credibility of rehabilitants concerning inpatient psychosomatic rehabilitation. Both study groups receive the usual written information for preparation (TAU). The patients of the experimental group have access to various videos on the study website until their inpatient rehabilitation begins, the patients of the placebo group receive no special treatment. The investigators hypothesize that the experimental group gains more positive outcome expectancy and treatment credibility compared to the control group.
