Correction to: Mapping PedsQL™ scores onto CHU9D utility scores: estimation, validation and a comparison of alternative instrument versions (Quality of Life Research, (2020), 29, 3, (639-652), 10.1007/s11136-019-02357-9)

Abstract

In the original publication of the article, the equation CHU9DPredicted = exp(BETAPredicted)/(1 + exp(BETA Predicted)) was formatted incorrectly under Model 2. The correct version is provided below: Model 2—assuming a 15-year-old female with a score of 50 in each functioning dimension: The original article has been corrected. BETAPredicted = 1.611745 − 4.724501 * (Physical Functioning) + 2.447472 * (Emotional Functioning) + 0.9967647 * (School Functioning) + 4.144465 * (Physical Functioning)2 + 0.1686639 * (Male) − 0.1198546 * (Age) CHU9DPredicted = exp(BETAPredicted)∕(1 + exp(BETAPredicted)) → BETAPredicted = 1.611745 − 4.724501 * (50∕100) + 2.447472 * (50∕100) + 0.9967647 * (50∕100) + 4.14..
