DISCERN score by video category. DISCERN score items (rows) are shown for single videos (columns, n = 85). The categorial DISCERN item scoring ranges between 1 (not addressed, blue), 2 (partially adressed, white), 3 (partially addressed, light pink), 4 (partially addressed, dark pink), and 5 (fully addressed, red). The item 2 “aims achieved” was not assessable (NA, black), when item 1 “explicit aims” was scored with 1, i.e. criterion not met. The sum of the DISCERN score ranges between min. 16 and max. 80. The videos are grouped by video category
