"The Göteborg quality of life instrument" - A psychometric evaluation of assessments of symptoms and well-being among women in a general population
Sammanfattning
The objective of this study was to examine with psychometric analysis techniques the potentials for constructing valid composite variables of "The Göteborg quality of life instrument". Use of a few, distinct scales instead of a number of single questions should increase statistical power because the number of comparisons is greatly reduced and problems of chance findings are thus minimized.
