Using Generalized Estimating Equation Analysis in a Study of Relaxation Training in Patients With Insomnia.

Background: The purpose of this study was to examine the improvement in insomnia patients using Relaxation Training, and to use the Generalized Estimating Equation model (GEE-I) to analyze the results of repeated measurements and observe the difference between the subjective perception and the objective measurement of sleep duration. Methods: There were 24 subjects diagnosed as insomnia who completed the treatment course and 5 times evaluation. Of the 24 subjects, 7 accepted the sleep electroencephalogram (EEG). Relaxation training shortened the duration of sleep onset time and decreased the frequency of night awakening.
