Psychometrische eigenschappen van en overlap tussen de OQ-45, BDI en WHOQoL-Bref bij uitkomstonderzoek

Abstract

Due to several developments in the (mental) health care, outcome monitoring has been seen as more and more important. For this purpose disorder specific instruments (BDI), symptom based generic instruments, instruments measuring daily functioning (both OQ-45), and instruments measuring quality of life (WHOQoL-Bref) are widely used. This study investigated whether these instruments overlap and whether they actually measure something else. Also was examined if the psychometric properties found in previous research could be replicated, which proved to be the case. Significant overlap between the instruments was found. The use of a disorder specific instrument (BDI) in addition to the two other instruments does not seem to lead to additional information and therefore doesn't seem to be necessary.
