title: [Intra-sleep awakenings in poor sleepers, 20 to 30 years of age. Correlation with anxiety level and personality (author's transl)].
abstract: Recordings were made from 43 poor sleepers between the ages of 20 and 30 for at least 4 consecutive nights. Three subject groups were formed on the basis of the awakenings occurring up to the sixth hour of sleep. The first group, with an average of 61 min wakefulness, is characterized by the abundance of long-lasting waking periods. The second group, with 18 min average wakefulness, showed the highest absolute number of awakenings, almost all of which were very brief. The third group, with 6 min average wakefulness, showed a slightly lower number of awakenings, but these were almost exclusively micro-waking periods. The temporal distribution of the waking periods was also different in the first group, in which the longest waking periods occur during the first hour of sleep and remain elevated until the fifth hour of sleep. The latency for falling asleep is particularly high for this group. A correlation exists between the amount of time awake up until the sixth hour of the night and the subject's anxiety level and the neuroticism index. 65% of the subjects obtained pathological scores on one or more MMPI scales. According to the order of frequency these were scales Sc, Pd and Pt. No preferential profile was found.
