The DISCERN tool was used to evaluate the reliability of the videos.
 Results: Of the 77 videos analyzed according to GQS, 36 (46.8%) were high quality, 31 (40.2%) were intermediate quality and 10 (13.0%) were low quality.

Significant differences were only found between the groups in respect of the DISCERN scores (p
