The predictive validity of the Psychiatric Rework Readiness Scale (PRRS) for work continuation in the case of typical individuals who return to work after sick leave has previously been reported. The present study expanded on previous studies examining the predictive validity of the PRRS with participants in the Re-Work program, which aims to increase the resilience of patients returning to work with mental illness. In addition, sociodemographic factors and clinical factors that influence work continuation were considered.
Of the 76 patients enrolled in the Re-Work program at NTT Medical Center Tokyo between January 2014 and September 2016 who returned to work before the survey date of May 31st, 2017, 56 consented to participate in this study. The average duration of work continuation, as estimated by the Kaplan-Meier method, was 715 days (95% confidence interval:547-884 days). The total PRRS score before return-to-work significantly predicted work continuation, with lower scores predicting a shorter duration of work continuation. Individual scores on the PRRS subscales of "basic daily life rhythm," "symptom impact," "relationship with the workplace,"and "health management" also significantly predicted work continuation, with lower subscale scores predicting shorter work continuation. Among the sociodemographic factors examined, female gender predicted shorter work continuation. For clinical factors, earlier age of onset and longer total duration of sick leave in the past predicted shorter work continuation.
This study confirmed the predictive validity of the PRRS for work continuation for Re-Work program participants, consistent with previous results demonstrating its validity for typical individuals who returned to work without participating in the program. This scale may thus be used as an objective assessment tool in the context of decisions related to return-to-work. The influence on work continuation of the total past duration of sick leave has previously been reported, and should be explained to individuals considering participation in the Re-Work program as a factor that may limit the effects of the treatment. However, this impact has also been observed for non-program participants who returned to work, and therefore may not necessarily be a contraindication for participation in the Re-Work program.
