Table 3. Actigraphy Parameters --Individual vs. Group Comparison.

	Individual		Group		p-value¹
Sleep Parameter	Baseline (mean, SD)	Treatment (mean, SD)	Baseline (mean, SD)	Treatment (mean, SD)
Sleep Latency (min)	59.8 (31.6)	39.5 (21.6)	56.0 (25.2)	39.7 (21.5)	0.63
Sleep Efficiency, %	76.2 (6.2)	78.7 (5.1)	76.4 (8.0)	79.8 (6.0)	0.56
WASO (min)	63.8 (28.4)	59.3 (27.3)	60.4 (22.1)	58.3 (23.7)	0.37
Total Sleep Time (min)	486.9 (48)	481.1 (49.5)	482.4 (56.7)	488.3 (50.3)	0.37

SD = standard deviation; min = minutes, WASO = wake time after sleep onset

Comparison of individual vs. group education. The change in each actigraphy parameter from baseline to treatment was compared between groups (independent samples t-test).
