TABLE 2.

The comparison of the STAI-state score before and after the video-based MMI or written information in the two groups

	Control group (n=38)	Video-based MMI group (n=36)	p
STAI-S pre-informational	45.4±5.8	45.1±5.3	0.812
STAI-S post-informational	45.2±5.1	41.1±4.9	0.004
p’	0.210	<0.001

Data are given as mean±standard deviation. STAI-S: State-trait anxiety index-state; MMI: Multi-media information. p the p value derived from the comparison of the video and control groups. p’ the p value derived from the comparison of the pre- and post-informational STAI-S scores.
