Effectiveness of an educational video in older adults’ perception about falling risks: a randomized clinical trial

Abstract

Objective: to assess the effectiveness of using an educational video in comparison with verbal nursing guidelines in increasing older adults’ perception of falling risks. Method: this is a randomized clinical trial in a cluster, with 138 community older adults, randomized into an intervention group, which watched an educational video, and a control group, which received verbal instructions. The perception of falling risks was assessed by FRAQ-Brazil in the pre-test and after a 30-day follow-up. Student’s t-test was used for dependent samples to compare intragroup means and for independent samples to compare intergroup means. The effect size was determined by Cohen’s d. Results: in the intragroup analysis, intervention and control groups had an increase in perception, with a statistically significant difference between pre-and post-tests. In the intergroup analysis, the control group showed a greater increase in the perception of falling risks in relation to the intervention group (p = 0.013), with Cohen’s d of small effect. Conclusion: the use of an educational video and verbal instructions increased older adults’ perception of falling risks, with better results in the control group. However, the effect size was small.

Some considerations on the principles of the Cognitive Theory of Multimedia Learning for instructional video design for the elderly

“…In spite of no paper in Table 4 satisfy inclusion criterium (iv)empirical results comparing video designs, the studies from Sá et al (2020) and Sá et al (2022) are related, not only each paper has six authors, from which five authors are the same, the second paper is the continuation of the first, that is, it is based on the instructional video produced in the first. The combination of the two papers would be a study that satisfies inclusion criteria (i), (ii), and (iii) (except criteria iv), and it would not be included in any exclusion criteria.…”

“…This local scenario from Brazil suggests that first most local publications regarding instructional videos are about constructing and validating videos. Almost all papers present the construction and validation of instructional video, except Sá et al (2022), that is, 12 in 13. However, if the work of Sá et al (2020) and Sá et al (2022) is considered as one, as previously suggested, then, in fact, all papers would be related to constructing and validating educational videos (12 in 12).…”

A possible reason for this situation is that the avalilability of educational videos in Portuguese may be still insufficient for conducting studies that compare instructional video design techniques.…”

“…They provided a table of the script with 3 columns (scene, image and text, and audio), a figure with the storyboard, and tables with the descriptive statistics of their study, but they did not provide a link to the video, a website, or any reference to it. Sá et al (2022) developed an educational video to assess the effectiveness of using an educational video in comparison with verbal nursing guidelines in increasing older adults' perception of falling risks, and as they described it was a randomized clinical trial in a cluster, with 138 community older adults, randomized into an intervention group, which watched an educational video, and a control group, which received verbal instructions. They assessed the perception of falling risk by FRAQ-Brazil (Lopes & Trelha, 2013) in the pre-test and after a 30-day follow-up.…”
