Background
People with chronic diseases are often limited in their workability. Evaluating and enabling workability is central in rehabilitation. The aim of this study was to evaluate validity and utility of workability assessments in German for persons with chronic diseases.
Methods
The study is a systematic review. First, we systematically searched for literature in the databases Medline, CINAHL, PsycInfo, Cochrane HTA Database, DARE, CCMed, Sowiport, and BASE using following keywords: evaluation tool, chronic disease, workability, validity, and utility. Then, we evaluated the content and the quality of the studies based on criteria and decided if they were included.
Results
In total, validity and utility of eight workability assessments are described based on 74 studies. The assessments are: Productivity Costs Questionnaire (iPCQ), Work Instability Scale for Rheumatoid Arthritis (RA-WIS), Screening-Instrument Arbeit und Beruf (SIBAR), Screening-Instrument zur Feststellung des Bedarfs an medizinisch-beruflich orientierten Maßnahmen in der medizinischen Rehabilitation (SIMBO), Valuation of Lost Productivity Questionnaire (VOLP), Work Ability Index (WAI/ABI), Work Limitations Questionnaire (WLQ), and Work Productivity and Activity Impairment Questionnaire (WPAI).
Conclusion
The results revealed the availability of eight workability assessments for persons with chronic diseases in German language. They have strengths and weaknesses in relation to the construct, purpose, application, and evidence base. These could be the base for choice of an assessment. Overall, we suggest using workability assessment in order to meet the legal requirements for the use of standardized assessments and the increasing demand to establish evidence of the effectiveness of interventions.
