An experimental study with three groups is planned over a time period of 18 months. The computerized expert system (Intervention Group, IG) will be evaluated in comparison to a well established program (Active Control Group (ACG)) and a questionnaire-only group.
Patients in the intervention group receive an interactive, computerized expert system, whereas patients in the Active Control Group (ACG) get an interactive computerized standard program. The standard program has already been proven to be effective but does not tailor treatment components to the individual needs of the patients. Patients in the Passive Control Group (PCG) are asked to answer the questionnaires only.
Rehabilitation patients (N = 1000) will be recruited in three rehabilitation clinics and followed up over six measurement points: at t1 and t2 the computer interventions will take place in the beginning and at the end of their rehabilitation stay; t3 and t4 are booster-sessions via telephone (6 weeks and 6 months after discharge from rehabilitation). Furthermore, patients will receive a questionnaire per mail at t5 (12 months after discharge) and at t6 (18 months after discharge).
