Table 2: Efficacy measurements with rating scales baseline vs. week 12 in study group.

Variable	Baseline (N = 28)	Week 12 (N = 28)	t/z	p
HAMD 7	14.5 (8)	3 (9)	-4.54^z	0.005^*
HAMD 17	24.64 (6.19)	6.27 (6.71)	13.76^t	0.005^*
HAMD 21	26.5 (13)	5.5 (14)	-4.62^z	0.005^*
HAMA	21 (14)	4 (8)	-4.51^z	0.005^*
BDI	23 (15)	2.5 (13)	-4.43^z	0.005^*
BAI	19 (17)	5 (8)	-3.87^z	0.005^*
PSS14	48.83 (7.79)	34.74 (9.46)	5.17^t	0.005^*

For continuous variables, mean (standard deviation) or median (interquartile range) is given according to the test applied and t scores are obtained for paired t test, z scores are obtained for two related samples test.
Note: *p ˂ 0.05. BL: Baseline; HAMD: Hamilton Rating Scale for Depression; HAMA: Hamilton Rating Scale for Anxiety; BDI: Beck Depression Inventory; BAI: Beck Anxiety Inventory; PSS: Perceived Stress Scale.
