Table 3. Comparison of mean change scores for the Arousal Scale during each visit (n = 20) .

Visit	Mean Score			Mean Change Score
	Pre	Mid	Post	Pre-to-Mid	Mid-to-Post	Pre-to-Post P value	Pre-to-Post % Change
1	2.60	2.95	2.70	0.35	0.25	*0.10	3.85
2	2.60	2.65	2.60	0.05	0.05	0	0
3	2.70	2.90	3.05	0.20	0.15	0.35	12.96
4	2.40	3.25	3.25	*0.85	0	*0.85	35.42
5	2.50	3.10	3.15	*0.60	0.05	*0.65	26.00
6	2.50	3.05	3.00	*0.50	0.05	*0.45	20.00
7	2.60	3.25	3.40	*0.65	0.15	*0.8	30.77
8	2.20	3.00	2.95	*0.80	0.05	*0.75	34.09

One-Way Repeated Measures ANOVA for mean change scores between each visit pre-to-mid Arousal Scale was statistically significant along a linear trend (P = 0.009) and within-subjects (sphericity assumed-P = 0.02). That is, the trend from 0.35 (visit 1) to 0.8 (visit 8) was statistically significant (P = 0.009).

One-Way Repeated Measures ANOVA for mean change scores between each visit pre-to-post Arousal Scale was statistically significant along a linear trend (P = 0.05). That is, the trend from 0.1 (visit 1) to 0.75 (visit 8) was statistically significant (P = 0.05).

* Statistical significance (P < 0.05).
