The World Health Organization Quality of Life Assessment Instrument (WHOQOL-100): Validation Study with the Dutch Version

Abstract
In this study, we examine the reliability and validity of a new quality-of-life (QoL) instrument, the Field Trial Version of the World Health Organization Quality of Life assessment instrument (WHOQOL-100). Two-hundred-and-twenty persons, 147 healthy individuals, and 73 chronic fatigue syndrome (CFS) patients completed the WHOQOL-100 and a test battery of related measures. The WHOOQL-100 has a fairly good internal consistency and a good validity.
