Factor analysis of subjectively reported sleep habits, and the nature of insomnia

  • M. W. Johns (a1)
Synopsis

Factor analysis was performed on variables used to describe subjectively the sleep habits of three groups of subjects—male patients, female patients, and medical students. Similarities in the six factors from each analysis indicate the existence of dimensions of variation which are common to normal sleep habits and insomnia.
