Participatory Rehab Goals Online: Participatory rehabilitation goals: Goal processing during rehabilitation preparation, rehabilitation stay, and rehabilitation aftercare - PREZO

= 222 patients undergoing treatment at an orthopaedic rehabilitation clinic took part in the PREZO study. N = 162 (=73% of all 222 participants included at t0) completed all 4 online surveys. The data from these individuals were included in the final analysis. Multivariate analyses were calculated for all target variables using the general linear model with the repeated measures factor time (4) and the group factor (2). The critical interaction of the two factors was significant for the scales depression, perceived impairment of health and impairment of ability to work due to pain. The effect sizes for the respective catamnesis time points were calculated for all target variables surveyed (Cohen's d). While both groups improved equally at the early catamnesis time point 1 month after discharge, the intervention group showed greater effect sizes for almost all outcome measures at the later catamnesis time points than the control group, which deteriorated again 3 and 6 months after discharge.
