Processprofiling and Processmonitoring


Controlling instrument for vocational rehabilitation

In vocational rehabilitation, process control becomes increasingly important. Therefore, new validated instruments are required (Riedel et al., 2009). Such a control instrument has to focus on reintegration, support individual way of rehabilitation and be able to ensure self-determination of insurants during rehabilitation process.

Based on the new rehabilitation model, RWTH Aachen and 19 vocational promotion centers developed a process-based profiling and monitoring instrument, abbreviated PP/PM.

PP measures key competencies, health competencies and specific vocational competencies to record the initial situation of insurants. The assessment can be repeatedly used to monitor - PM - and control the whole rehabilitation process and get constant feedback about competencies and development.

In this project, PP/PM will be evaluated to ensure a high-quality and user-friendly instrument after a three-year developmental period.

In six studies PP/PM will be tested regarding statistical quality criteria - objectivity, reliability, validity - and satisfaction.

To ensure an objective valuation basis for PP/PM, characteristic definitions and an user guide will be developed. To ensure objectivity, interrater reliability was measured. The results show high correlations between different raters from 65 to 100%.

The empirical analysis for reliability was done with help of retest-reliability between .64 and .86, interrater-reliability beteween .65 and .96 and an internal consistency between .68 to .95. Furthermore content, criteria and construct validity was tested.

To measure content validity, experts and employers were contacted. Results show that employers advice space for further work related key competencies.

To measure criteria validity, 700 rehabilitation patients in 14 BFW’s were testes with PP/PM. The results reveal that there are differences between patients who finish their rehabilitation measure and patients who don’t finish their training. Competencies of successful patients are always evaluated in a more positive way. Further analyses reveal that unsuccessful patients can be determined with help of the first competence assessment. Soft facts, such as psychological condition or trustworthiness are important for reintegration success. With help of the tool, deficits can be determined and promoted at an early stage.

To measure construct validity correlations between self and external assessment were reported. To evaluate economy, the process time were measured. Process time ranges from 5 to 15 minutes. To provide a final feedback, 15 minutes are needed. To ensure acceptance, the user were included in the development process. In Sum, all parties are positive about PP/PM.

Results reveal that PP/PM is a sufficiently objective, reliable and valid method. Furthermore, PP/PM is widely accepted by users. In summary, PP/PM should be implemented in vocational promotion centers.
