Health-related quality of life as an outcome variable in Parkinson’s disease
Therapeutic Advances in Neurological Disorders, 04/03/2012
Martinez–Martin P et al. – The methodology section offers an overview of generic, disease specific, and recommended health–related quality of life (HRQoL) scales in Parkinson’s disease and the most important psychometric attributes a scale should meet. The interpretation of HRQoL outcomes is complex and not intuitive. Thus, appropriate reporting of data is crucial in order to calculate relative change, a result that facilitates understanding to what extent an intervention is beneficial.
