Table 1 Sleep and behavioral functioning across conditions

From: Preliminary fMRI findings in experimentally sleep-restricted adolescents engaged in a working memory task

  Baseline Sleep restriction (SR) Healthy duration (HD)
Actigraphy data    
   Duration (hr)*** 7.7 ± 1.1 6.3 ± 0.5 8.7 ± 0.4
   Efficiency* 89% ± 8 92% ± 6 85% ± 8
Sleep diary data    
   Duration (hr)*** 7.6 ± 1.0 6.4 ± 0.2 9.1 ± 0.3
   Latency (min)** 12.6 ± 6.3 7.2 ± 6.4 32.5 ± 12.4
   Difficulty waking scale* 5.2 ± 3.3 7.0 ± 2.8 2.4 ± 2.1
Behavioral data per parent    
   Attention problems (raw) 3.7 ± 2.5 5.7 ± 2.0 3.0 ± 1.9
   Daytime sleepiness (raw)* 2.3 ± 1.5 4.3 ± 2.3 1.5 ± 1.6
  1. p < .10; *p < .05; **p < .005, ***p < .001 comparing the SR vs. HD sleep conditions. These findings are comparable to those shown in the full sample of the parent study. See Beebe et al. [3] for a full description of the parent study, including sleep and behavioral measures.
