Effectiveness of the Internet-Based, Job-Related Aftercare GSA-Online Following Inpatient Psychosomatic Rehabilitation: Results of a Randomized Controlled Trial

Abstract

In order to sustain the treatment results of medical rehabilitation in the long term and to support the transfer of learned strategies into everyday life, outpatient aftercare is often indicated. This is especially true for psychosomatic rehabilitation patients with occupational stress, for whom reintegration into working life is a particular challenge. Since access to care services close to home is limited, internet-based aftercare interventions offer the possibility of timely and flexible aftercare tailored to the patient's needs. In a randomized controlled trial, the internet-based job-related aftercare GSA-Online proved to be effective across indications with regard to job-related and health-related outcome criteria. The aim of the present study is to examine these outcome criteria in a subsample of patients undergoing inpatient psychosomatic rehabilitation. Occupationally stressed rehabilitation inpatients were assigned to the intervention (IG) or control group (CG) by means of cluster randomization after meeting the inclusion criteria and participating an inpatient vocational stress management training. After discharge from rehabilitation, patients in the IG were given access to GSA-Online for twelve weeks. In the intervention, maladaptive social interactions in the workplace were identified with the help of self-written blog posts and addressed with the help of therapeutic comments. The active CG received access to selected online information on health-promoting behaviors. Target measures included subjective prognosis of gainful employment (SPE), depressiveness (PHQ-9), and anxiety (GAD-7). Self-report measures were assessed at the end of aftercare and at follow-up (twelve months after the end of rehabilitation). Missing values were replaced using multiple imputation. Ninety-one percent of the IG (N=89) and 70% of the CG (N=106) logged on to the website at least once. There were no group differences in the subjective prognosis of gainful employment at the end of aftercare but a trend toward more optimistic scores in the IG at follow-up. Significantly lower psychological distress was observed in the IG, especially with regard to anxiety (at both measuring points) but also with regard to depressive symptoms (follow-up) and experience of stress (end of intervention). In the subsample of psychosomatic rehabilitation, the internet-based, job-related aftercare GSA-Online led to a significant reduction in psychological symptoms. Regarding the subjective prognosis of gainful employment, there was at least a trend in favor of IG. A larger sample is needed to more closely examine the results of this exploratory evaluation. Additionally measures to increase adherence in the IG should be explored.
