“…One GOALS assessment included all eight procedural phase-based video clips from one MIE procedure. To obtain a 95% confidence interval to be ± 1 point on the grading scale, at least 30 crowd workers per video clip assessment were deemed necessary based on previous research [ 17 , 18 , 29 , 30 ]. In addition, two MIE experts were randomly appointed per GOALS assessment.…”

Background Video-based assessment by experts may structurally measure surgical performance using procedure-specific competency assessment tools (CATs). A CAT for minimally invasive esophagectomy (MIE-CAT) was developed and validated previously. However, surgeon’s time is scarce and video assessment is time-consuming and labor intensive. This study investigated non-procedure-specific assessment of MIE video clips by MIE experts and crowdsourcing, collective surgical performance evaluation by anonymous and untrained laypeople, to assist procedure-specific expert review. Methods Two surgical performance scoring frameworks were used to assess eight MIE videos. First, global performance was assessed with the non-procedure-specific Global Operative Assessment of Laparoscopic Skills (GOALS) of 64 procedural phase-based video clips < 10 min. Each clip was assessed by two MIE experts and > 30 crowd workers. Second, the same experts assessed procedure-specific performance with the MIE-CAT of the corresponding full-length video. Reliability and convergent validity of GOALS for MIE were investigated using hypothesis testing with correlations (experience, blood loss, operative time, and MIE-CAT). Results Less than 75% of hypothesized correlations between GOALS scores and experience of the surgical team (r < 0.3), blood loss (r = − 0.82 to 0.02), operative time (r = − 0.42 to 0.07), and the MIE-CAT scores (r = − 0.04 to 0.76) were met for both crowd workers and experts. Interestingly, experts’ GOALS and MIE-CAT scores correlated strongly (r = 0.40 to 0.79), while crowd workers’ GOALS and experts’ MIE-CAT scores correlations were weak (r = − 0.04 to 0.49). Expert and crowd worker GOALS scores correlated poorly (ICC ≤ 0.42). Conclusion GOALS assessments by crowd workers lacked convergent validity and showed poor reliability. It is likely that MIE is technically too difficult to assess for laypeople. Convergent validity of GOALS assessments by experts could also not be established. GOALS might not be comprehensive enough to assess detailed MIE performance. However, expert’s GOALS and MIE-CAT scores strongly correlated indicating video clip (instead of full-length video) assessments could be useful to shorten assessment time. Graphical abstract

“…In video advertising, marketers have used fast playback speed video or audio for instrumental reasons, such as saving advertisement costs [10] and creating a fast-paced atmosphere [5]. In addition to commercials, sped-up video is also studied in sports [11,12], education [13][14][15][16], and clinical research [17]. More recently, fast playback speed videos have become popular on social media and live streaming platforms, partly because fast-playback options are accessible and built-in functions on most video apps (e.g., TikTok, YouTube, and iQIYI); this allows users to choose playback speed that is faster than the original video over a wider range (e.g., ×1.25, ×1.5, ×1.75, ×2).…”

Urgency perception plays a vital role in addressing the issue of climate change. However, little is known about how to promote the perceived urgency of climate change and its potential influence on proenvironmental intention and behavior. This research focuses on a potentially significant but less studied factor in video communication: video playback speed. The current research explores the effectiveness of video playback speed as a subtle behavioral nudge to influence urgency perception and proenvironmental response in the context of climate change. We conducted two survey-embedded experiments in which participants watched a climate change video playing at either normal or fast speed and then completed measurements. Data were collected first in an undergraduate sample (n = 75) and then in a general population sample (n = 300) and analyzed using Mann–Whitney U tests, chi-squared tests, and moderation analysis in SPSS. The results reveal that a fast playback speed of climate change video decreases the perceived urgency of climate change for younger consumers, not for older consumers. However, video playback speed does not influence proenvironmental intention and behavior. These findings enhance understanding of when video playback speed affects urgency perception and proenvironmental tendency, and provide valuable insights for climate change communication.
