文摘
- •
We applied a bi-factor model to the analysis of somatic symptom reports.
- •
The structure was invariant, allowing longitudinal comparisons of symptom scores.
- •
Introduction of a new power line affected separate symptom domains differently.
- •
As effects vary across domains, ignoring the structure may lead to false conclusions.
