Comparison of cognitive load using the Cognitive Load Component (CLC) questionnaire
| Outcomes | 360° virtual reality video group (n = 32) | Two-dimensional virtual reality video group (n = 32) | Mean Difference (95% confidence interval) | P-value |
|---|---|---|---|---|
| CLC-total | 20.1 (2.0) | 18.9 (2.5) | 0.5 (0.03–1.0) | .04 |
| Intrinsic cognitive load | 4.7 (1.6) | 3.7 (1.4) | 0.7 (0.2–1.2) | .01 |
| CLC-1: How difficult did you find the simulation session? | 2.4 (1.0) | 1.8 (0.8) | 0.7 (0.2–1.2) | .04 |
| CLC-2: How complex was the content covered in the simulation session? | 2.3 (0.8) | 1.9 (0.7) | 0.4 (−0.001–0.8) | .05 |
| Extraneous cognitive load | 7.5 (1.1) | 7.5 (1.1) | −0.3 (−0.5–0.03) | .82 |
| CLC-3: How clear did you find the instructions for the simulation session? | 3.8 (0.6) | 4.0 (0.5) | 0.1 (−0.5–0.03) | .08 |
| CLC-4: How relevant did you find the simulation session for your current practice? | 3.7 (0.8) | 3.5 (1.0) | 0.2 (−0.3–0.6) | .40 |
| Germane cognitive load | 7.8 (0.8) | 7.7 (1.4) | 0.09 (−0.40–0.58) | .67 |
| CLC-5: How focused were you during the simulation session? | 3.9 (0.7) | 3.7 (0.9) | 0.2 (−0.2–0.6) | .36 |
| CLC-6: How much did you learn from the simulation session? | 3.9 (0.5) | 4.0 (0.8) | −0.1 (−0.4–0.3) | .71 |
| Data are expressed as mean (standard deviation). The CLC-total (range = 6–30) is defined by the sum of six items, using a five-point rating scale and the score of each type of cognitive load is calculated as the sum of the two specific scales (range = 2–10) | ||||
