Comparison of mean state and trait anxiety scores before and 4 weeks after intervention between counselling and control groups

Variable	Counselling group	Control group
	Mean (SD) (n = 38)	Mean (SD) (n = 38)	Mean difference (95% confidence interval)	p-value
State anxiety
Pre intervention	44.8 (10.4)	43.2 (10.6)	1.6 (−3.2 to 6.4)	0.507
Post intervention	35.1 (8.0)	47.1 (10.2)	−12.0 (−14.4 to −9.6)	<0.001
Trait anxiety
Pre intervention	44.9 (9.9)	41.7 (8.8)	3.2 (−1.0 to 7.5)	0.136
Post intervention	37.0 (8.2)	45.6 (9.1)	−10.9 (−12.7 to −9.1)	<0.001

For comparison of groups before intervention Independent t-test and after intervention, ANCOVA test with controlled baseline values was used

The range of state and trait anxiety scores is 20–80
