Table 4 Decision conflict scale scores and proportion of patients with high decision conflict (decision conflict scale score ≥ 37.5)

PVIC¹ group	T1 after video aids, (n = 30)	T2 after in-person IC, (n = 30)	P value
DCS score, mean (95%CI)	19.0 (14.3-23.7)	13.5 (8.5-18.6)	0.002⁴
DCS score ≥ 37.5², n (%)	2 (6.7)	0 (0)	0.150
SIC³ group	T1 after in-person IC, (n = 30)	T2 after video aids, (n = 30)	P value
DCS score, mean (95%CI)	20.5 (15.4-25.6)	12.4 (8.0-16.9)	< 0.001⁴
DCS score ≥ 37.5², n (%)	6 (20)	2 (6.7)	0.129

¹The pre-consultation video informed consent group consists of patients who viewed the video before the in-person informed consent consultation.

²A decision conflict scale score ≥ 37.5 was defined as patients with high decision conflict.

³The standard informed consent group consists of patients who first underwent an in-person informed consent consultation, followed by supplementary video viewing.

⁴Statistically significant.

PVIC: Pre-consultation video informed consent; IC: Informed consent; DCS: Decision conflict scale; CI: Confidence interval; SIC: Standard informed consent.
