Levels of adjustment, depression and attitudes toward death among good and poor sleepers.

Administered the MMPI, Self Rating Depression Scale, and a survey of attitudes toward death to 20 males and 16 females designated as good sleepers and 24 males and 25 females designated as poor sleepers. Compared with good sleepers, poor sleepers scored in a more pathological direction on 11 of the 13 MMPI scales and on the Self Rating Depression Scale. Poor sleepers also reveal a significantly greater preoccupation with death although, paradoxically, they do not admit to fear of their own death. Results confirm previously reported personality differences between good and poor sleepers. No association was found between sex and quality of sleep.
