title: Sleep duration and self-reported Type A behavior: a replication.
abstract: Scores on the Jenkins Activity Survey (Form T)(Glass, 1977) were compared for 58 and 70 university students who reported, respectively, a regular sleep pattern of less or more than 8 hr per night. Replicating a previous report (Hicks et al., 1979), subjects who slept fewer hours scored higher on Type A behavior questions than those who slept more hours. However, for subjects with a less stable sleeping pattern, Type A scores for the two groups (ns = 72, 23) did not differ.
